Options for the question have not been provided. They are as follows:
(1) DNA in muscle cells
(2) base sequences in liver cells
(3) genes in an egg cell
(4) number of chromosomes in a fetal bone cell
Answer:
(3) genes in an egg cell
Explanation:
Evolution is the change in characteristics of a species which it develops over the time. These changes can be a result of natural selection, genetic drift, founder effect etc. They are passed from one generation to another hence the alleles for them get fixed in the population.
For evolution to occur, change should take place in germ cells. Germ cells are the one which fuse to form the organisms of next generation. If there is a change in their genes, it would also appear in next generation, unlike changes in genes of somatic cells. Since egg cell is a germ cell it is the correct answer.
Answer:
This person can be described as an environmentalist.
Explanation:
An environmentalist is a person who has adopted environmentalism as a philosophy that makes this person work and manages to direct their activities towards the preservation of the environment and sustainable development. These people seek to teach others to preserve the environment and seek to defend it through politics, economics and any other social factor that can help to achieve this goal.
The person presented in the question above is an environmentalist, because, as we can see, this person is available to give a lecture on environmental preservation, interacts with environmental activist groups and seeks political support to address issues on climate issues, sustainability and biodiversity .

Carrector pill muscles hair follicles
Explanation:
melanocytes and keratin are present in the epidermis
Answer:
They probably use aerobic respiration.
Explanation:
A travel distance of 11.500 kilometers in 9 days covered by flying surely requires a lot of energy.
- If cells are fermenting, the ATP (energy) they generate only comes from glycolysis, which produces 2 ATP molecules.
- If they are using aerobic respiration, glucose is completely oxidized to CO₂ through glycolysis and the Citric Acid Cycle, and the electrons enter the electron transport chain to finally reduce oxygen into water. In the complete process, up to 36 ATP molecules are produced.
In sum, aerobic respiration is much more efficient to generate energy than fermentation, so it's probably the main metabolism of the flight muscles in bar-tailed godwits.
DNA Fingerprinting is a way to find a specific individual. It is more specific than simply identifying a specie or a particular trait. It is a sort of personal identifier. DNA uses micro satellite to make to make identification much easier. DNA fingerprinting is prevalent in the world of criminal forensic.
