The genetic material <span>that children inherit from their parents </span>and the physical similarities of children to their parents are the evidence for evolution. Comparative anatomy is used to show relatedness from generation to generation by having similar DNA sequences or patterns and traits.

Answer:

Homologies and vestigial structures  are two evidences of the evolution of how DNA and comparative anatomy used to show relatedness

Explanation:

Living organisms have characteristics that make them similar to others, which may suggest that at some point in the history of life on Earth, they shared a common ancestor. When we look at the limbs of a crocodile and a rat, for example, we find that, despite their differences in morphology, they are quite similar in anatomy, suggesting that they may be related. In this case, we say that the characteristic is homologous, that is, it has a similar embryonic origin, but it does not always perform the same function.

Trace structures are structures that are atrophied and have no apparent function in an organism. The presence of these organs can be interpreted as evidence of evolution, since the structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.

Basal metabolism is the largest component of total energy expenditure. True or False
irina1246 [14]

Answer: True

Explanation: The basal metabolic rate (BMR) is responsible for about 75% of our calorie expenditure daily. The Basal metabolic rate (BMR) is the energy expenditure rate per unit time by humans or animals at rest. it is the amount of energy per unit of time that we need to keep the body functioning daily even when at rest. Some of these processes that occur even when we are at rest includes blood circulation, brain function, regulation of body temperature, nerve function, cell growth and breathing.

nadya68 [22]
I think most scientists would not respect this researchers claim.
It doesn't seem like the researcher followed the steps of the scientific method.
1.) Making an observation.
2.)Asking questions.
3.)Forming a hypothesis.
4.)Conducting an experiment.
5.)Analyzing Data.
6.)Drawing a conclusion.
7.)Showing work to others.

Publishing his/her work would be the very last step after completing everything else.

Approximately 21% of the human genome is comprised of nucleotides containing C. Given this information, calculate the percentage
azamat

Answer:

(a) 21% of the human genome is comprised of G.

(b) 29% of the human genome is comprised of T.

(c) 29% of the human genome is comprised of A.

Explanation:

According to Chargaff's rule, a DNA molecule has the same amount of pyrimidines (T and C) as purines (A and G), and G pairs with C and A pairs with T.

If 21% of the genome contains C, then 21% also contains G.

Therefore 21% + 21% = 42% of the genome is comprised of G+C.

The other 58% is comprised of A+T, and because they pair with each other, 29% will correspond to A and 29% will correspond to T,
