Following the rule of "like dissolves like", the hydrophilic head of the phospholipid molecule dissolves readily in water. The long fatty acid chains of a phospholipid are nonpolar, and thus avoid water because of their insolubility
What is atom in a chemical reaction?
Answer:
the atoms are molecules that react with each other, they're called reactants
Explanation:
Modern plant-breeding techniques (artificial selection in action) have reduced genetic variability in many of our most commercially valuable plants. To most people, that would generate a shrug. However, a biology student that has studied evolution understands the problem with this. Briefly explain why there is an issue with this.
Answer:
There is an issue with the artificial selection.
Explanation:
There is an issue with this artificial selection because the genetic variability is reduced when we do again and again the artificial selection. In the artificial selection, the selected genes are combined with the one another and does not allow natural fusion or combination of genes that is responsible for the genetic variability in the organisms so that's why we can say that this artificial selection is an issue that reduce genetic variability.

You are studying nuclear lamins and use recombinant DNA technology to alter the coding sequence of a nuclear lamin gene. The alteration you make creates a situation such that the gene now codes for a nuclear lamin protein that can no longer be phosphorylated when the nuclear envelope is broken down during mitosis. What do you predict would happen if the cell only had the altered nuclear lamin gene (and not the unaltered version)
Answer:
Nuclear lamins will no longer disassemble during mitosis
Explanation:
The nuclear lamina is a fibrillar network inside the nucleus of eukaryotic cells, between the inner nuclear membrane and the peripheral chromatin. Nuclear lamins (also called simply lamin proteins) are intermediate filament-type proteins and represent the major building blocks of the nuclear lamina. During mitosis, the nuclear lamina is disassembled by hyperphosphorylation of nuclear lamins and lamina-associated proteins. The protein responsible for phosphorylating nuclear lamins is p34cdc2, a protein kinase that has a key role in controlling cell cycle progression. In consequence, a mutant form of the nuclear lamin proteins that cannot be phosphorylated will no longer be able to disassemble during mitosis.

Why do cells use fat and starch for long-term energy storage instead of ATP molecules?
O ATP is used for long-term storage, while fat and starch are used for immediate energy.
O ATP is used for short-term energy and to build molecules of starch and fat.
O Fat and starch are unstable and can be stored short-term, while ATP molecules are stable and stored long-term.
O Fat and starch are stable if used as energy immediately, while ATP is used as long-term storage.
Answer:
Cells use fat and starch for long-term energy storage instead of ATP molecules because fat and starch are more efficient energy storage molecules than ATP.ATP is a molecule used for immediate energy, not for long-term energy storage.
Fat and starch are complex carbohydrates that can be broken down to release energy. Fat molecules are primarily composed of carbon and hydrogen, while starch is made of glucose molecules.Both fat and starch can be broken down through cellular respiration to produce ATP molecules that can be used to power various cellular processes.
However, because fat and starch molecules contain more chemical energy than ATP, they can provide a much larger amount of energy over a longer period of time.
Furthermore, ATP molecules are relatively unstable and cannot be stored for long periods of time, while fat and starch can be stored in specialized cellular structures for long-term energy needs.
How many phenotypes are possible from the 3 alleles coding for human blood? A 3 B. 4 C. 5 D. 6
There are 4 phenotypes are possible from the 3 alleles coding for human blood. The correct option is B.
What is phenotype?The set of qualities or characteristics that can be observed in an organism are known as its phenotype in genetics.
The word includes an organism's anatomy, developmental processes, physiological and biochemical characteristics, behaviour, and the outcomes of behaviour.
The genotype of an individual is their own DNA pattern. More specifically, the two alleles a person acquired for a particular gene are referred to by this phrase.
The clinical presentation of a patient is the observable expression of this genotype, or phenotype.
A, B, AB, and O are the four phenotypes of blood that can occur. The gene that determines blood type has three alleles. Six distinct genotypes are possible because there are three different alleles.
Thus, the correct option is B.

Answer:
Gene therapy to correct defective genes that cause diseases.
Explanation:
Gene therapy refers to the procedure that involves the introduction of nucleic acids (DNA or RNA) into the cells of an organism for the purpose of correcting abnormalities, such as a mutations or in other words to treat a genetic disease.Gene therapy entails bringing a normal and functional gene known as a trans-gene into a cell with altered gene. Another method can bring RNA capable of partially regulating or blocking the expression of an altered gene.The nucleic acids are introduced into the patient's cells by means of a viral vector or injected directly into the cells in the form of naked DNA.pls mark brainliest
The consensus is that the coelacanths and lungfishes (Sarcopterygii) represent an evolutionary link between ray-finned fishes and tetrapods. What is the major feature in the Sarcopterygii that supports this hypothesis?
Answer:
Choana, paired fins with a fleshy base over a bony skeleton, persisting notochord, 2 dorsal fins and nares.
Explanation:
Sarcopterygii also known as lobe-finned fishes which usually possess a choana, paired fins with a fleshy base over a bony skeleton, persisting notochord, 2 dorsal fins and nares are present internally. The lungfishes are considered the closest living relatives of tetrapods because of the presence of some common features. The African lungfish has epithelial crypts located at the base of the lamellae of the olfactory epithelium that express markers of the vomeronasal receptors in tetrapods.
Which statement is FALSE?Question 39 options: Water can hold an unlimited amount of oxygen. Water can hold less oxygen than air can. Underwater organisms need oxygen. A small decrease in dissolved oxygen can have an effect on aquatic life. Underwater organisms use oxygen in cellular respiration.
Answer: Water can hold an unlimited amount of oxygen.
Explanation:
Water cannot hold an unlimited amount of oxygen because it would get to a point where it is saturated as it needs to hold Hydrogen as well. Air on the other hand, has significantly more space for oxygen as it contains only 21% and can keep taking more.
Underwater organisms need oxygen for respiration and a small decrease in the oxygen available in water affects aquatic life because they rely on it to survive.
Your service club is offering a prize for the best community educational plan. Not only would you love to win the prize, but you think this is a good opportunity to advocate against ATOD abuse. You know that ATOD abuse can be a big problem in a community, and you want to help people learn about it.
Before you start creating your campaign, it's important to research what is going on with ATOD abuse in your community.
1. Using local news media sources, find five news stories related to ATOD abuse in your community. For each news story, identify a barrier that prevented the person or people involved from making better decisions regarding ATOD use.
1. Hailey Hesch started using dr#gs when she was 12 years old. She experimented with a lot of hardcore dr#gs like h3roin. A barrier that prevented her from stopping her addiction to the feeling she got when she took dr#gs. She said it made her feel amazing and really happy.
2. Jeremy B smoked a lot of w33d, drank, fought people, and chased girls around with his friends frequently. After a while, he started to use and experiment with other dr#gs like h3roin and d0pe. A barrier that prevented him from making healthier choices was due to curiosity.
3. Kristina started her dr#g addiction with painkillers she took for an injury. She took them as they were prescribed at first, but after losing an opportunity to get a scholarship, she started abusing the painkillers. However, the painkillers were not enough, so she started using hardcore dr#gs to try to reach a "High". Nothing worked so then she kept abusing them more and more. She noticed that she was becoming very unstable, so she forced herself to get treatment. A barrier that prevented her from making better decisions was because she was blinded by grief and anger.
4. Adam was a 27 year old who was very athletic and smart. No one would have seen it coming, but he died due to a dr#g overdose. There was no one in his entire family that knew about his addiction, and when they found out, it was too late. A barrier that made him addicted is unknown, but some people suspect that it was because of friends or outside influences.
5. Cassie was a smart and successful woman who was very well-rounded. She went to church, donated to charities, and helped children with activities like tutoring and basketball. However, her parents started noticing unusual behavior from her. She shut herself off, had intense mood swings, and looked physically exhaused. Their suspicions were confirmed when she collapsed in the middle of the day. The doctor's diagnosis stated that she overdosed on m3th and that she was in a permanent coma. Later, the doctor broke the awful news to her parents, Cassie had irreversible brain damage and was a lost cause, so she died after being taken off of life support. A barrier that prevented her from making better choices was that no one took action when her behaviour drastically changed.

Cross-contamination of food occurs when a. perishable foods are kept at room temperature for more than 2 hours b. a utensil contaminated with a microorganism from a previously handled food contacts a second food c. two or more food handlers work on the same food d. two or more microorganisms grow in the same food
ANSWER: B
explanation: from what I learned in culinary arts, this is kind of a trick question. Its not asking how foods can get contaminated, its asking how CROSS CONTAMINATION can occur. Cross contamination occurs in three ways think of it like this: food-to-food, equipment-to-food, and people-to-food. The answer has to be between B and C. But the answer is B, because the utensil is already contaminated and it is coming in contact with another food. The two or more food handlers working on the same food are not bringing anything contaminated into the situation. Unless they are contaminated (by they I mean their hands lol) then it cross contaminates but that's not it lol im 99% sure the answer Is B.
Cross-contamination of food occurs when two or more foods come into contact with each other, transferring microorganisms from one food to another. This can happen in a number of ways, including direct contact, contact with a contaminated surface or utensil, contact with a contaminated food handler, or contact with airborne microorganisms.
What is the most common type of cross-contamination ?The most common type of cross-contamination is direct contact, which can occur when one food touches another. This is especially true of perishable foods, which should not be kept at room temperature for more than two hours.
If they are kept at room temperature longer than this, bacteria and other microorganisms can quickly multiply, potentially leading to cross-contamination.
Another common way for cross-contamination to occur is through contact with a contaminated surface or utensil. If a utensil that has been used to handle a food contaminated with microorganisms comes into contact with a second food, the microorganisms can transfer to the second food and cause cross-contamination.
Similarly, if two or more food handlers work on the same food, their hands can transfer microorganisms from one food to another, leading to cross-contamination. Finally, if two or more microorganisms grow in the same food, they can interact with each other and potentially cause cross-contamination.

You are running a genetics experiment. Which of the following will help you obtain the copies of the gene you need?
A. Ribosome
B. Mesosome
C. Plasmid
D. Nucleus
Answer:
D
Explanation:
i think this is the answer because the nucleus contains threads of DNA called chromosomes.which can help in a genetic experiment.
I hope this helps
In the given context, Nucleus would help in obtaining the copies of the gene.
The nucleus controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information.
What is Nucleus?In cell biology, the nucleus is a membrane-bound organelle found in eukaryotic cells.
The nucleus was discovered by Robert Brown in 1831.
Nuclear DNA is a multiple long linear molecules in a complex with a large variety of proteins, such as histones, to form chromosomes. The genes within these chromosomes are structured in such a way to promote cell function.
The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression and thus control the center of the cell.
The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle.
Nucleus houses an organism’s genetic code, which determines the amino acid sequence of proteins critical for day-to-day function, it primarily serves as the information center of the cell has been found that replication happens in a localized way in the cell nucleus.
What is Ribosomes?A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during protein synthesis or translation. The process of protein synthesis is a primary function, which is performed by all living cells.
Ribosomes are specialized cell organelles and are found in both prokaryotic and eukaryotic cells. Every living cell requires ribosomes for the production of proteins.
This cell organelle also functions by binding to a messenger ribonucleic acid (mRNA) and decoding the information carried by the nucleotide sequence of the mRNA.
They transfer RNAs (tRNAs) comprising amino acids and enter into the ribosome at the acceptor site. Once it gets bound up, it adds amino acid to the growing protein chain on tRNA.
What is Mesosome?Mesosome is formed by an extension of the plasma membrane into the cell wall. These extensions are usually in the form of vesicles, tubules, and lamellae.
The main use of mesosomes are:
- Synthesis of a cell wall.
- DNA replication.
- Distribution of daughter cells, respiration, secretions, etc.
What is Plastid?Plastids are double-membrane organelles which are found in the cells of plants and algae.
Plastids are responsible for manufacturing and storing of food. These often contain pigments used in photosynthesis and different types of pigments that can change the color of the cell.
Different types of plastids with their specialized functions are:
- Chloroplasts
- Chromoplasts
- Gerontoplasts
- Leucoplasts
