_____ is the change of adaptations in a population of organisms over time.

Which method would allow you to study the behavior of a tiger in its native habitat in India?

OLga [1]

The answer is field investigation.

A field investigation includes observation of free-living animals in their natural habitat without affecting them, their behavior, or their habitat. So, observation of tigers' activity in their native habitat is an example of the field investigation. The investigator would simply observe their behavior, not affecting the tigers in any way.

What is an ethical concern regarding genetic engineering? privacy of genetically tested individuals unnatural and potentially da

Lerok [7]

I believe that all the above are ethical concerns regarding genetic engineering. Ethics is the study of moral or socially acceptable behavior. With the advent of genetic engineering and the ability to modify the genome of various organs, many ethical questions arise concerning the various scenarios and possibilities. There are many ethical concerns regarding genetic engineering in plants, animals, and humans. One of the ethical concerns regarding genetically modified plants used for food is whether the nutritional value will be sacrificed in favor of a higher yield or drought resistantancy.

1. What are Chargaff's rules?

kotegsom [21]

1)Chargaff's rules state that DNA from any cell of any organisms should have a 1:1 ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

2)DNA structure

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.

3)A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil). A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons. One or more phosphate groups.

4)DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.

5)The diagram has show in above.

6)complementary base pairing is necessary because the double helix shape would not be the same if not. Doubles would only pair with doubles and the singles to singles.

HOPE THIS HELPS YOU.
