The image, in which A represents a gene, shows a harmless mutation that has occurred in a species' genome. Which is the most
plausible way that this mutation may eventually benefit the species?
A)
Multiple copies of genes increase gene expression and protein synthesis,
improving fitness
B) One copy of the gene may mutate further and begin to function differently
from the original.
C) Individuals with different copy numbers of the gene will not be able to
mate, resulting in speciation.
D) Individuals with the mutation are not able to produce offspring and will be removed from the gene pool.
Answers
Answer:B
Explanation: I took this test
One copy of the gene may mutate further and begin to function differently from the original is the most plausible way that this mutation may eventually benefit the species.
What is Mutation?A mutation is a change to an organism's Genetic sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Our cells constantly undergo mutations, yet surprisingly few of these have an adverse impact on our health. A mutation is never so advantageous in real life.
Therefore, One copy of the gene may mutate further and begin to function differently from the original is the most plausible way that this mutation may eventually benefit the species.

Explain the relationships and trade-offs among amounts of skin pigmentation, Vitamin D production, and protection from UV radiation.
Answers
Answer:
Ultraviolet radiation leads to DNA mutations in the melanocytes, which are skin cells that contain melanin. Melanin level is inversely associated with the ability of skin cells to produce vitamin D
Explanation:
Ultraviolet (UV) radiation is a well-known environmental factor that causes mutations in the DNA of melanocytes, which are skin cells that produce melanin. Moreover, melanin is a protective pigment whose main function is to block UV radiation, thereby protecting the body from DNA damage and, consequently, from cancer (skin cancer). Abundant melanin levels can decrease the ability of the body to synthesize vitamin D, the only vitamin that can be synthesized with sunlight. In consequence, darker skin is associated with a higher risk of having vitamin D deficiency.

A- Fossil evidence showing that prokaryotic cells required an environment free of oxygen.
B- Genetic comparisons revealing that living and extinct organisms share commonalities.
C- Geological dating techniques supporting theories regarding Earth's age.
D- Geological studies proving that volcanic gases resemble those from early Earth.
Answers
Answer:
A - Fossil Evidence showing that prokaryotic cells required an environment free of oxygen.
Explanation:
Thanks OP for answering your own question!
The data that provides the strongest evidence (that is, the most valid evidence) that early Earth conditions provided what was necessary for life is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.
What are genetic comparisons in evolution?Genetic comparisons are the most direct and reliable source of evidence supporting the theory of common ancestry and the origin of life on Earth. All living organisms share a common set of genetic building blocks, such as DNA and RNA, and use the same genetic code to translate this information into the proteins that make up living organisms. Genetic comparisons reveal similarities between living organisms and extinct organisms, such as ancient bacteria and archaea, which provides further evidence for the common ancestry of all life on Earth.
Hence, it is revealed by genetic comparisons, which reveal that living and extinct organisms share commonalities. This is option B.

[v] He found that in F2 progeny there were tall as well as short plants.
[vi] The three quarter plants were tall and one quarter was short.

➜ Speciation is the formation of new species from the pre-existing population.
Factors responsible for speciation:
Genetic drift. Natural selection.Geographical isolation. Mutation.Geographical isolation cannot be a major factor in the speciation of a self-pollinating plant species because physical barrier cannot be created in self-pollinating plants.
Speciation is how a new kind of plant or animal species is created. Speciation occurs when a group within a species separates from other members of its species and develops its own unique characteristics.
