Answer:
Mutations can occur before,during and after mitosis and meiosis if a mutation occurs in cells that will make gametes by meiosis or during meiosis itself it can be passed on to off spring and contribute to genetic variability of the population.
may be this was ur answer of ur question.
Mutations and meiosis are in that they both produce genetic variation
in organisms.
Meiosis is a type of cell division that involves the production of sex cells or in sexual reproduction. They produce unique daughter cells and in situations where there is a mutation in this process, it is usually passed to the offspring which leads to genetic variation.
Mutations are also usually passed to the daughter cells as it occurs in their
cells during reproduction which makes it similar with meiosis in the area of
genetic variation.

When does mRNA editing take place?
Answer:
After transcription, some RNA molecules are altered to contain bases not encoded in the genome. Most often this involves the editing or modification of one base to another, but in some organisms can involve the insertion or deletion of a base. Such editing events alter the coding properties of mRNA.

Red-green colorblindness is an X-
linked recessive trait that
prevents the eye from
differentiating red and green
colors. Look at the pictures. What
problems could a person
experience as a result of
perceiving the colors so similarly?
Answer:
look,Examples of X-linked recessive conditions include red-green color blindness and hemophilia A: Red-green color blindness. Red-green color blindness means that a person cannot distinguish shades of red and green (usually blue-green), but their ability to see is normal.
Red-green colorblindness is an X-linked recessive disorder in humans.
What do you mean by disorder?An illness that disturbs the normal physical or mental functions of any individual.
The allele of colorblindness resides on X-chromosome, which means the male is affected with one mutant allele. while both the alleles are required to be mutant to cause the disorder in females. Another example of X-linked disorder includes Hemophilia. Red-green colorblindness reveals that an individual cannot able to differentiate the shades of red and green but occupy the normal vision.
Therefore, Red-green color blindness is an X-linked recessive disorder in humans.

Consider a habitat with prairie dogs, bison, and red-tailed hawks. Another
species of hawk that eats prairie dogs, the ferruginous hawk, migrates into
the area. What effect will this change most likely have on the prairie dog and
red-tailed hawk populations?
O A. The prairie dog population will decrease, the red-tailed hawk
population will stay the same, and the bison population will
increase.
B. The prairie dog population will decrease, the red-tailed hawk
population will decrease, and the bison population will increase.
C. The prairie dog population will decrease, the red-tailed hawk
population will stay the same, and the bison population will stay
the same
O D. The prairie dog population will decrease, the red-tailed hawk
population will decrease, and the bison population will stay the
same.
Answer:
B. The prairie dog population will decrease, the red-tailed hawk population will decrease, and the bison population will increase.
Explanation:
I'm not given context; however, I am assuming that the prairie dog preys on the bison because the bison is commonly known as a herbivore.
If another predator who preys on the prairie dog is introduced, there is increased competition with the red-tailed hawks. Although this doesn't directly impact the population of red-tailed hawks, it reduces its food supply (of the prairie dog) because it is being shared, so it will have less food to grow at the optimal level.
With the increased consumption of the prairie dog, naturally, that would leave its prey; the bison, to have a lower level of predation, thereby the population increasing.

Which characteristic is most useful in correlating Devonian-age sedimentary bedrock in New York State with Devonian-age sedimentary bedrock in other parts of the world?
Complete question:
Which characteristic is most useful in correlating Devonian-age sedimentary bedrock in New York State with Devonian-age sedimentary bedrock in other parts of the world?
a. Color
b. Index fossils
c. Rock types
d. Particle size
Answer:
b. Index fossils
Explanation:
Fossils are animal and vegetable rests found in different strata of sedimentary rocks. Sedimentary layers deposit chronologically, so they are used to reflect history. They keep in each layer some of the forms of life that inhabited that area in the past. These fossils turn to be very useful while dating ages. The term Index fossils refer to those fossils that only existed in a given era or geological period during evolution.
Index fossils must:
Be easily recognizable and distinguishable from all the other fossilsHave lived in a relatively short geological periodPresent a wide geographic distributionHave lived in different sedimentary basinsAppear in different types of rocksBe abundantIn the exposed example, we are looking for a correlation between the Devonian-age sedimentary rock layers from New York with the Devonian layers of other parts of the world. This comparison is the same period (Devonian) and in places that might be far away from each other, meaning there was a wide geographical distribution of the species.
A quick evolution and extinction contribute to narrow the geological period of their existence, increasing the chronological precision. Widely distributed fossils allow geologists to establish relationships between rocks that are far away from each other.

Answer:
B. Anaphase
Explanation:
The stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.
The phase of mitosis which is shown below in the picture is Anaphase. During this phase, chromosomes break at centromeres.
What do you mean by Mitosis?Mitosis may be defined as a process where a single cell divides into two identical daughter cells.
Anaphase is the phase of mitotic cell division where chromosomes break into chromatids that are separate from each other and are pulled towards the opposite pole with the help of spindle fiber.
Therefore, the phase of mitosis which is shown below in the picture is Anaphase.

can dogs the poison ivy?
Explanation:
Though cases of a dog being affected by poison ivy are rare, if you have a canine companion with sensitive skin, you should keep him away from the plant, just in case. “After being in an area with poison ivy or oak, you should wash your dog,” Nold suggests.
Answer:
Unfortunately, yes, your dog can get poison ivy. Fortunately, dogs getting poison ivy is not as common as it is in humans. It is tougher for poison ivy to make contact with the dog's skin since they are covered in protective fur. If your dog does get poison ivy it is easily treatable.

2. A researcher adds an enzyme to a sample of human DNA to see if the
DNA changes. Which result would best support the conclusion that the
enzyme had no effect on the DNA?
The DNA has uracil bases.
The DNA has unpaired nitrogenous bases.
The DNA has a single strand with nucleotides and a sugar-phosphate backbone.
The DNA has a double helix shape with nucleotide pairs and sugar-phosphate
backbones.
Answer:
has a single strand with nucleotide and a sugar phosphate backbone
Answer:
hi
i'm not really sure but i think its the second option
Explanation:
enzymes when they are active usually hydrolyzes things
so in the second one we read that we can see unpaired nitrogenous bases
these bases are:
adenin timin citosin goanin
those are for DNA . in RNA timin is changed with uracil
so these means the hydrogen bond between them are hydrolyzed by enzyme
so we see the effect of enzyme on DNA
what can exponential growth happen
In exponential growth, a population's per capita (per individual) growth rate stays the same regardless of population size, making the population grow faster and faster as it gets larger. In nature, populations may grow exponentially for some period, but they will ultimately be limited by resource availability.

Each cell of the muscles of a certain bug contains 28 chromosomes.
a. How many chromosomes are in its sperm cells?
Answer:
14 chromosomes
Explanation:
In the gametes of an organism, there are always half of how many chromosomes there are in the somatic cells of the organism. For example, if there are 4 chromosomes in the somatic cells, that means that there are 2 chromosomes in the gametes.
Somatic cells are body cells. They include everything from skin cells to brain cells to stomach cells.
Gametes are reproductive cells. They're the sperm and egg cells.
So if the muscle cells have 28 chromosomes, that means all somatic (or body) cells of that organism have 28 chromosomes.
So the gametes would have half of that amount:
28/2 = 14
So the sperm cells of this organism would have 14 chromosomes.
