You classified organisms based on anatomical structure and development. Scientists also use DNA to classify organisms. Considering the basic process of evolution, why do you think it’s important to also consider DNA and gene patterns during the classification of organisms?
Answer:
By studying genetics and DNA, we can get the best idea of how species are related to each other, and therefore how to classify them. The genetic code of a species is not fixed, however. It changes over time! This is why we also need to factor in evolution.

¿Porque las vitaminas, las sales minarales y el agua se consideran reguladores?
Answer:
Vitamins and minerals boost the immune system, support normal growth and development, and help cells and organs do their jobs. For example, you've probably heard that carrots are good for your eyes. It's true! Carrots are full of substances called carotenoids (pronounced: kuh-RAH-teh-noydz) that your body converts into vitamin A, which helps prevent eye problems.
Vitamin K helps blood to clot, so cuts and scrapes stop bleeding quickly. You'll find vitamin K in green leafy vegetables, broccoli, and soybeans. And to have strong bones, you need to eat foods such as milk, yogurt, and green leafy vegetables, which are rich in the mineral calcium.

2. Calculate the rate of population increase for the whales and the seals from the data in table 2, trial 1. What does this rate represent?
Hint: From the point of zero change on the graph to the highest population achieved is a change in time of 100 months. (Refer to the science skills practice in the lesson for the correct formula for the rate of population change.)
Answer:
There are no tables but it should be a bell curve. as a population of whales rise the population of seals will decrease, eventually creating a plateau in the whale population. shortly after the plateau in the whale population the whale population will begin to decline ( as food becomes less available) causing the seal population will begin to rise and restabilize. this pattern should continue cyclically creating a wave function on a graph!

What happens when the density of a medium increases?
Gene X always produces the same mRNA (one splice form) and the same protein in all cells in which it is expressed. The same amounts of gene X mRNA and protein are present in brain, kidney, and heart cells. However, the activity associated with the protein is present only in the heart. Which of the following are possible explanations?
a. A splicing factor necessary for removing all of the primary transcript's introns is present only in the heart.
b. A splicing factor necessary for removing all of the primary transcript's introns is present only in the brain and kidney.
c. Protein X is phosphorylated only in the heart.
d. Protein X is phosphorylated only in the brain and kidney.
There are two explanations for this phenomenon: phosphorylation of the protein X in the heart activates its function (Option C) or phosphorylation of the protein X in the kidney and the brain deactivates its function (Option D). Therefore, both Option C and Option D are correct.
Phosphorylation is a posttranslational protein modification that is capable of activating or deactivating protein function.
Phosphorylation alters the three-dimensional structure of a protein, thereby modifying its function (i.e., activate or deactivate the target protein).
Phosphorylation occurs at specific amino acids (e.g., serine and threonine residues) of the target protein.
Moreover, mRNA splicing (RNA processing) occurs before the protein state, it is a transcriptional process. This process consists in removing the non-coding regions or 'introns' from pre-mRNA and subsequent joining protein-coding regions or 'exons' to enable the translation of the mRNA into a protein.
In consequence, in this case, it is possible that 1-phosphorylation of the protein X in the heart activates its function, or 2-phosphorylation of the protein X in the kidney and the brain deactivates its function. Therefore, both Option C and Option D are correct.

How will you evaluate the information that you retrieve from the library, by giving specific examples in one of your subject specialization
Answer:
You might think the answers to the questions “what is a library?” and “what is the Internet?” are pretty obvious. But actually, it is easy to get them confused, and there are a number of research resources that are a bit of both: library materials available over the Internet or Internet resources available in the library.
Understanding the differences between the library and the Internet and knowing where your research comes from is crucial in the process of research writing because research that is available from libraries (either in print of electronic form) is generally considered more reliable and credible than research available only over the Internet. Most of the publications in libraries (particularly in academic libraries) have gone through some sort of review process. They have been read and examined by editors, other writers, critics, experts in the field, and librarians.
In contrast, anyone with appropriate access to the Internet can put up a Web page about almost anything without anyone else being involved in the process: no editors, other writers, critics, experts, or anyone else review the credibility or reliability of the evidence.
However, the line between what counts as library research and what counts as Internet research is becoming blurred. Plenty of reliable and credible Internet-based research resources are available: online academic and popular journals, Web-based versions of online newspapers, the homepages of experts in a particular field, and so forth.
Let’s begin with the basics of understanding the differences between libraries and the Internet.
Libraries are buildings that house and catalog books, magazines, journals, microfilm, maps, government documents, and other resources. It would be surprising if you attended a community college, college, or university that did not have a library, and it would be equally surprising if your school’s library wasn’t a prominent and important building on campus.
As you might expect, libraries at community colleges, colleges, and universities tend to specialize in scholarly materials, while public libraries tend to specialize in non-scholarly materials. You are more likely to find People magazine or the latest best-selling novels in a public library and a journal like College English and scholarly books in a college library.
Many universities have different libraries based on distinctions like who tends to use them (“graduate” or “undergraduate” libraries) or based on specific subject matter collected within that particular library (education, social work, law, or medicine). Almost all college and university libraries also have collections of “special items,” which include items like rare books, maps, and government documents.
Almost all universities, colleges, and community colleges in the United States provide students and faculty with access to the Internet so they can use email and the World Wide Web, or even so they can publish Web pages. Millions of people both in and out of school have access to the Internet through “Internet Service Providers,” which are companies both large and small that provide customers access to the ‘net for a monthly fee.

The data table and the cladogram below provide information about the evolutionary history of several different species of animal. Using this information, which of the following is true of trout?
They are more closely related to salamanders than they are to birds.
They are more evolved than salamanders and lizards.
They evolved into a separate species due to the presence of lungs.
They have jaws and lungs but lack claws or nails, feathers, and mammary glands.
Answer:
They are more closely related to salamanders than they are to birds.
Explanation:
According to the data, trout are more closely related to salamanders than birds.
The first data table shows how the salamander only has one extra trait that the trout does not have (lungs).
On the other hand, birds have three extra traits that the trout doesn't have (claws/nails, feathers, and lungs).
The cladogram further shows how trout are more closely related to salamanders compared to birds.
Trout and the salamander are closer together on the cladogram, while the bird is further away. This means they are more related on the evolutionary timeline.
So, the correct answer is that They are more closely related to salamanders than they are to birds.
The statement which is true about Trout is as follows:
They are more closely related to salamanders than they are to birds.Thus, the correct option is A.
What is Cladogram?A Cladogram may be defined as a type of family tree or classification tree which is based on evolutionary relationships. It is also known as a phylogenetic tree.
Trout and the salamander are positioned closer to one another on the cladogram while the bird is being far away. The presence of lungs is marked from the salamander, so trout do not have lungs.
Trouts evolved from Hagfish but not from salamanders and lizards. Trouts only have jaws but lungs, claws or nails, feathers, and mammary glands.
Therefore, the correct option for this question is A.

A. False, it should read "Muscles only work to produce movement by pushing, they cannot pull."
B. False, it should read "A muscle works to produce movement by pushing and pulling."
C. False, it should read "Muscles only work to produce movement by contracting, they cannot push or pull."
D. True
It should be noted that muscles only work to produce movement through pulling, muscles cannot push. Therefore, the statement is true.
Muscles allow people to move by pulling in the joints. Muscles are required to breathe, exercise and stay healthy.
There are three main form of muscles in the human body and they're:
• Skeletal muscles: The muscles give the body its shape as they help in holding the skeleton together.
• Smooth muscle: They're also called the involuntary muscle. They consist of fibers and are controlled by the nervous system. They help in maintaining blood pressure.
• Cardiac muscle: This is the muscle that's found in the heart. It helps in ensuring that the heart function well.
In conclusion, muscles only work to produce movement by pulling, they cannot push.

On an ECG, what does Ventricular Fibrillation mean?
A. Tachycardia, the heart is beating too fast.
B. There is no coordinated contraction of the heart, death is possible in minutes.
C. A lack of oxygen to the heart.
D. Brachycardia, the heart is beating too slow.
Answer:
A
Explanation:
I believe the answer is A because Ventricular Fibrillation means the heart is beating irregularrly, and too fast. Sometimes up to 500bpm
There is no coordinated contraction of the heart, death is possible in minutes. Therefore option B is correct.
Ventricular fibrillation (VF) is a life-threatening cardiac arrhythmia characterized by chaotic electrical activity in the ventricles, the heart's lower chambers.
During VF, the heart loses its ability to pump blood effectively, leading to a lack of blood flow to vital organs.
Without immediate intervention, such as defibrillation to restore a normal heart rhythm, the condition can rapidly progress to cardiac arrest and cause death within minutes.
Unlike tachycardia (A) or bradycardia (D), which involve abnormal heart rates, VF is a more severe and critical situation with disorganized electrical signals and ineffective pumping, requiring urgent medical attention.
Therefore option B There is no coordinated contraction of the heart, death is possible in minutes. is correct.

The nucleus of the cell is similar to the_______ system of the body.
The nucleus of the cell is similar to the Neurological system of the body.
What is Nucleus?According to the Cell Biology, nucleus may be a membrane found in organism cells.
The nucleus contain all of the cell's ordering except mitochondrial DNA and in plant cell, Plastid DNA.
Nuclear DNA is organized as multiple long linear molecules in a very complex form with a large variety of proteins, like histones, to make chromosomes.
The nucleus maintains the integrity of sequences and controls the activities of the cell by regulation gene expression—the nucleus is, therefore, the control center of the cell
The nucleus contains nearly all of the cell's polymer, enclosed by a network of fibrous intermediate filaments and enveloped in an exceedingly double membrane referred to as the "nuclear envelope".
The nuclear envelope separates the fluid within the nucleus, referred to as the living substance, from the remainder of the cell. The scale of the nucleus depends on the scale of the cell it's contained in, with a nucleus usually occupying 8% of the whole cell volume.
The nucleus is the largest organelle in animal cells.
For example- In mammalian cells, the average diameter of the nucleus is approximately 6 micrometers (µm).
What is Neurological System or Nervous System of the body?The Nervous system could be a extremely advanced a part of associate degree animal that coordinates its actions and sensory data by sending signals to and from completely different components of its body.
In vertebrates it consists of 2 main components, the central system (CNS) and therefore the peripheral system (PNS). The CNS consists of the brain and neural structure.
The function of the system is to send signals from one cell to others, or from one a part of the body to others and to manage the body.
It will this by extracting data from the setting exploitation sensory receptors, causing signals that encrypt this data into the central system, process the data to work out associate degree applicable response, and causing output signals to muscles or glands to activate the response.
