Researchers use all of the following to study the impact of heredity on behavior except __________ studies. a. family b. peer c. adoption d. twin
Answer:peer
Explanation:
Researchers use all of the following to study the impact of heredity on behavior except peer.
Researchers use all of the following to study the impact of heredity on behavior except why?
When looking at studies relating to the heredity of traits we want to see if the child got a trait from the parents and their genes or from the way the child grew up with the parents.
That means that peers are not useful to us in those studies. Family is very useful since we need to look at the family and how it raises a child. Adoption is useful to see if an adopted child has the same traits as a biological child.
And twins are useful if they grew up in different circumstances from one another.
Thus, option "C" is correct.

Drea is comparing three organisms. Two have many of the same characteristics. But they have very few characteristics in common with the third organism. What can Drea infer about the relatedness of these three organisms?
Group of answer choices
The first two are unrelated, but each is related to the third.
Relatedness of the three organisms depends on the characteristics the first two share.
The first two are more closely related to each other than they are to the third.
The first two are equally related to the third.
Answer:
The first two are more closely related to each other than they are to the third.
Explanation:
The question tells us that the first two organisms share many common characteristics with each other, this tells us that the first two are related. We can cross out answer choice a. The question also tells us that the first two have very few characteristics in common with the third organism. With this much info given, the answer choices left are:
Relatedness of the three organisms depends on the characteristics the first two share.The first two are more closely related to each other than they are to the third.The first two are equally related to the third.First choice doesn't make any sense, there is no correlation between the common characteristics of the first two with the 3 organisms as a group.
Second choice makes sense and logical.
Third choice is wrong since the question does not give us enough information to know the first two is equally related to the third.
The first two are more closely related to each other than they are to the third. Is the right answer.

Muscle cells are made up of narrow spindle-shaped cells with a single, centrally located nucleus. Smooth muscle tissue, unlike the striated muscle, contracts slowly and automatically in the body.
At a cellular level, smooth muscle cells can be described as an involuntary, non-striated muscle cell. Smooth muscle cells consist of alternate thick and thin filaments which are not arranged into sarcomeres however it gives a non-striated pattern. On further microscopic examination, it appears homogenous.
