how can dna be used to help solve a crime
Answer:
dna can be used because no dna is the same unless there are identical twins. with using dna to solve a crime, you can test the dna to see if there are any similariteis or if they are exact. If there are similarities that means that someone related to that person is the person in charge of the crime. This is why dna evidence is one of the most important parts when looking at a crime scene because it is the most exact and precise way of convicting someone
Explanation:
Answer:
Each person’s DNA is unique.
Scientists use variable regions in DNA to create a DNA profile.
DNA samples can be taken from blood, bone, hair, or other body tissues and
products.
DNA from a crime scene can be compared to DNA from a suspect.
DNA typing can be used to solve old cases.

Why is meiosis important to sexually reproducing organisms?
Answer:
Meiosis is important for organisms that reproduce sexually because it is the cell division that serves to obtain gametes or sex cells.
Explanation:
Meiosis is a reductive cell division, involved in the gametogenesis process, where from a diploid cell haploid cells called gametes are obtained.
The gametes, also called sex cells, are responsible for containing the genetic information that each individual will transfer to their offspring.
In sexual reproduction, the importance of gametes is that the paternal and maternal gametes unite in a process called fertilization, to give rise to a diploid cell called a zygote.

Which causes genetic recombination?
Question 21 options:
alleles
crossing over
genes
hybrid crosses
Answer:
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.
Figure 1 represents a plasma membrane and molecules present on either side.
Part A: Describe the biological need for cells to be surrounded by a membrane that is selectively permeable for different materials.
Part B: Explain how the model shows selective permeability of the membrane to specific ions.
Part C: Describe the characteristics of the phospholipid bilayer that permit small hydrophobic lipid molecules to pass directly
Part D: Based on the model, explain whether the molecules shown crossing the membrane require energy to do so.
Answer:
A. Cell membrane is the outer layer of the cell that plays a role as the barrier between the internal and outer environment of the cell by regulating by allowing particles or substances to enter or exit the cell. It helps in maintaining the internal environment of the cell by allowing certain molecules to enter and stop other molecules.
B. Phospholipids bilayer is the part of the plasma membrane that makes it selective permeable. The plasma membrane does not allow ions with charges on the side of the molecules directly sodium, potassium, and many other ions are examples of this. Ions can enter or exit the cell with the help of the transporters or complexes.
C. There is hydrophilic-head and hydrophobic-tail present in the phospholipid bilayer in the structure of the cell membrane which makes it selectively permeable.
D. For active transport of molecules, the movement of molecules is always against the gradient which means movement from lower concentration to a region of higher concentration that requires energy (ATP).

When a plant cell, such as one from a peony stem, is submerged in a very hypotonic solution, what is likely to occur? A. The cell will burst. B. Plasmolysis will shrink the interior. C. The cell will become flaccid. D. The cell membrane will lyse. E. The cell will become turgid.
Answer:
The answer is "Option E".
Explanation:
The turgid relates to cells or tissues swelling from its transport of moisture. Some types of cells would become turgid because of moisture absorption in several distinct species. Its vacuole is swelling or pressure created mostly on cell walls, that's why whenever a cell membrane is submerged inside an extremely isotonic solution including a cell of a peony stem, the cell becomes turgid.
An hypotonic solution is a solution when compared to others have a relatively low solute concentration.
So when a cell is placed in a hypotonic solution, the cell will become turgid. (option E).
When this cell is placed in a hypotonic solution, there is the flow of water across the solution and its surrounding environment. In a hypotonic solution, the solute concentration is lower than inside the cell. This flow continues until there is a net flow and equilibrium is achieved. The cell in this process gains volume and becomes entirely turgid swelling up.Learn more about turgidity: https://brainly.com/question/18740086
What would most likely happen to a person who is not getting enough essential amino acids in his or her diet?
A.The body would synthesize the amino acids.
B.Muscle growth and repair would be limited.
C.Stored protein would break down.
D.The formation of proteins would increase.
Answer:
The correct answer I believe would be C
Explanation:
B. There would be reduced muscle growth and healing. The body cannot synthesise essential amino acids on its own; therefore, they must be consumed through diet.
What is the reason for body not using protein ?The body cannot use the protein it consumes for muscle growth and repair when a person's diet is deficient in critical amino acids. In addition to increasing the risk of injury, this can result in a loss of muscle mass and strength.
Additionally, in an effort to obtain the critical amino acids it requires, the body can start to break down protein that has been stored, which would result in a further loss of muscle mass and strength.
Alternatively, the body can create non-essential amino acids, thus whenProtein synthesis won't necessarily increase if a person isn't obtaining enough necessary amino acids. The body will instead concentrate on converting protein that has been stored into the vital amino acids it requires.
Therefore, a reduction in muscle growth and repair is the most likely consequence of consuming insufficient amounts of necessary amino acids.

Mutualistic fungus: lives around the roots of a tree and provide nutrients to the tree. Parasitic fungus: lives within the blood of another organism and cause disease. Saprophytic fungus: living in marsh environment and aids in biodegradation.
Fungus is a type of eukaryotic organism that belongs to the kingdom Fungi. Fungi are distinct from plants, animals, and bacteria, forming their own separate kingdom due to their unique characteristics and evolutionary history.
Mutualistic fungus establishes a symbiotic association with the roots of plants, forming structures called mycorrhizae. A parasitic fungus obtains nutrients from a living host organism, known as the host. They harm or exploit their hosts for their own survival and reproduction. A saprophytic fungus obtains its nutrients by decomposing dead organic matter.

Compare and contrast meiosis and mitosis. Show at least 5 sentences.
Mitosis and meiosis are two different kinds of cell cycle reproduction. They have many things in common together, such as being an asexual form of reproduction. Mitosis produces body cells, identical daughter cells that can grow an organism and replace old/dead cells. Meiosis on the other hand makes gametes; or reproductive cells. When mitosis happens, it goes through stage of the mitotic phase known as PMAT. PMAT stands for: prophase, metaphase, anaphase, and telophase; followed by cytokinesis. Meiosis on the other hand, goes through PMAT twice. After mitosis, the product is 2 identical cells, which are used to replace cells or to grow. After meiosis, 4 NON-identical cells are made, which contain HALF the set of chromosomes; hence being called a haploid cell.
Mitosis has only one round of cell division, while meiosis has two. Mitosis only occurs in body cells, while meiosis occurs in sex cells. Mitosis produces daughter cells, that are identical to the parent cell, while mitosis produces haploid/diploid cells that only have half of the normal number of chromosomes.
