The essence of meiosis is that a. specialized cell division reduces the chromosome number by half b. gametes are formed that are diploid c. specialized cell division doubles the chromosome number d. gametes are formed that are haploid e. a and d are correct
Answer:
e. a and d are correct
Explanation:
Meiosis produces 4 daughter cells that are haploid. Haploid means they have half of the chromosomes of the parent cell.
The essence of meiosis is that specialized cell division reduces the chromosome number by half and gametes are formed that are haploid.
Therefore option e is the right answer.
What is meiosis?A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material. These cells are our sex cells—eggs in females and sperm in males—and they are produced by a specific form of germ cell division in sexually reproducing species. Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome. The goal is to produce gametes, or sperm and eggs, that contain half of the parent cells' genetic makeup. Meiosis is characterized by DNA replication, two rounds of cell division, and the production of four daughter cells, each of which has half as many chromosomes as the parent cell.To learn more about meiosis, refer

plz give a correct answer for the question how do canine and molar differ
Answer:
Canines are the sharp, pointed teeth that sit next to the incisors and look like fangs. Dentists also call them cuspids or eyeteeth. Canines are the longest of all the teeth, and people use them to tear food
Molars are the flat teeth at the rear of the mouth. Each molar typically has four or five cusps. They are used exclusively for crushing and grinding. Wisdom teeth are also called third molars. They erupt from the age of 18 onwards but are often surgically removed.Their function is similar to that of the premolars, to grind, tear, and crush food. Molars have a large flat biting surface which makes them perfect for this job.

Consider the following geometric solids.
A sphere with a ratio of surface area to volume equal to 0.3 m
A right circular cylinder with a ratio of surface area to volume equal to
2.1 m?
What results would you expect if these two models were compared in a
diffusion test?
A. The rate of diffusion would be slower for the right cylinder,
B. The rate of diffusion would be the same for the two models.
0
C. The rate of diffusion would be faster for the right cylinder.
D. The rate of diffusion would be faster for the sphere.
Answer:
the rate if diffusion will be faster in the right cylinder
Explanation:
The surface area to volume ratio of the cylinder is higher. This means that in the cylinder more reactants are exposed at the surface and the rate at which diffusion takes place increases
Guinea pigs can produce different coat colors, white, brown, and mixed white/brown (agouti). The allele B is codominant with allele W (white coat). Cross an agouti-colored Guinea pig with a brown Guinea pig. What are the odds of the offspring?
Answer:
Brown
Explanation:because the agouti itself is a mixture that remains of a pale brown color and the melanin content in the animals is in the darker colors so it is more likely that the brown color is predominant to the agouti due to the content of melanin that it
The descendants of a cross between an agouti heterozygous (AB) colored Guinea pig and a brown (BB) colored Guinea pig are half heterozygous agouti, half homozygous brown. The correct option is A.
What exactly is codominance?Codominance is a genetic effect that happens whenever the alleles are expressed in heterozygotes.
In this particular instance, allele B co-dominates with allele W, resulting in heterozygous (WB) colored Guinea pigs like one of the parents.
Thus, the correct option is A.

b. Bobcats are another predator of snowshoe hare. If a population of bobcats immigrates to the
area, how is this likely to affect the habitat's carrying capacities for hare and lynx?
Answer:
Decrease population and carrying capacity.
Explanation:
If a population of bobcats immigrates to the area, the population of hare and lynx decreases that also affect the habitat's carrying capacities for hare and lynx because bobcats feed on both hare and lynx. Bobcats are very aggressive in nature, and has an aggressive hunting style. With these characteristics, the bobcats can hunt both hare and lynx which leads to decrease in population and carrying capacity.

Sperm cells are not normally exposed to blood, but if they are, the immune system may produce ____________ against sperm cells' ____________ and render someone sterile.
Answer:
Sperm cells are not normally exposed to blood, but if they are, the immune system may produce __auto-antibodies__ against sperm cells' __auto-antigens_ and render someone sterile.
Explanation:
Auto-antibodies are antibodies that can destroy cells from the same organism. They are mistakenly directed against organs or tissues of the same organisms, causing auto-immune diseases or affections. The autoantibodies action occurs when the organism fails in recognizing its own cells and faces them as strange elements.
Auto-antigen is the molecule produces by the body that fails in being recognized due to a break up in the tolerance mechanisms, triggering an immune response.
In the exposed example, sperm cells do not usually mix with blood. So when they do, blood cells recognize them as strange bodies and act against them. Sterility might be an effect of this auto-immune response.
