Rabbits can exhibit a number of colors in their coats: black, white, tan, brown, red, and grey. A disease randomly kills off most of the population and leaves only black and grey rabbits. Future generations are only black or grey. What is the term used to describe this
phenomenon? (1 point)
1. artificial selection
2. genetic drift
3. natural selection
4. genetic modification
please hurry and I will mark brainliest!
Answer:
2. Genetic Drift
Explanation:
Because it's simply by chance not on purpose or because their stronger.
Term used to describe the phenomenone where only black and grey rabbits survive and rest are killed randoml is called Genetic Drift..
What is genetic drift?As a result of a chance or random event, the frequency of an allele in a population drifts over time compared to the frequency of the other alleles. this is termed as genetic drift. Here, the rabbits with other coat colors were randomly killed off due to the disease which increased the frequency of the black and grey coat allele and hence the population drifts from multicolored coats to only black and grey colored rabbit coats.Hence the correct option here will be 2. Genetic Drift
other options are incorrect because:
Artificial selection is inducing the desired traits artifically which is not possible because the disease was a random event and not induced by humans.Natural selection is the survival of the fittest of the alleles and elimination of less fitter alleles. here it is not mentioned whether Black and grey coats were more fitter to survive than other coatsGenetic modification is a human made procedure and did not occur here.learn more about Genetic Drift here:

How is the reproductive rate of marine mammals
related to their status in regards to extinction?
Answer:
The fewer fish the less that can reproduce.
Explanation:
marine mammals with a slower reproductive rate are especially sensitive to disturbance , environmental changes and anthropogenic sources of stress because when populations of these organisms decline, recovery is especially slow . it takes a significant amount of time for these animals to reach reproductive maturity and they are commonly heavily invested in raising only one or two young ones every two to three years on average . therefore , populations of marine mammals with slow reproduction are in imminent danger when multiple sources of envirnmental pressure are acting in tandem over an extended period of time . The fewer fish the less that can reproduce.
More the reproductive rate, lesser the extinction and lesser the reproductive rate, more is the extinction.
What is reproductive rate?
The reproduction rate measures the conditions under which generations are replaced. This calculation can be made taking account of mortality (net reproduction rate) or without mortality (gross reproduction rate).
What is extinction?Extinction is a situation in which something no longer exists.
When the reproductive rate of marine mammals will be less, they will not be able to cover up the loss/death of their species caused by any reason and will ultimately lead to extinction.

Answer:
True
Explanation:
Pollen consists of one or more vegetative cells and a reproductive cell. A pollen grain itself is not the male gamete. In angiosperms and certain gymnosperms, the vegetative cell forms the pollen tube that grows to meet the unfertilized ovules, and the reproductive cell is the source of the sperm.

2. what are the patterns of expression for s3x-linked genes?
7. This pedigree is tracking dimples which are autosomal dominant. If this infomation was not given how could you deduce that this was in fact an autosomal trat, and not an X- linked trait? Provide a specific example from the ped gree:
The pedigree is not found here, but it is possible to track the inheritance of an autosomal/X linked trait by observing its presence in the family tree.
What is a pedigree?A pedigree is a genealogical tree used to track the inheritance pattern of a given trait in a family tree, which can be dominant or recessive.
An autosomal dominant trait is inherited in a dominant fashion and it is located on a pair of homo-logous autosomal chromosomes.
An X-linked trait is inherited on chromosome X and these traits show differential inheritance because males inherit only one X chromosome.

Don't copied from goo-gle
Force
- Force is defined as the act of pushing or pulling of an object. It can influence and alter the motion of an object.
Net Force
- Unlike Force which only defines a push or pull, Net Force is the combination of all forces acting on an object. The Net Force can be computed through Newton's Second Law, F=ma.

Are there any parts of the human body that get oxygen directly from the air and not from the blood? Are there nuclear reactions going on in our bodies?
Answer:
The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.
Nuclear reactions do indeed occur in the human body, but the body does not use them.
