Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct? a. The two proteins are very likely related evolutionarily. b. The differences in the sequences in many instances represent a conservative change (such as L for I). c. The differences in the sequences in many

Question is incomplete ,complete question is as follows :

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

1) The two proteins are very likely related evolutionarily.

2) The differences in the sequences in many instances represent a conservative change (such L for I).

3) The differences in the sequences in many instances represent a nonconservative change (such as D for A).

4) There is no correlation between the two proteins since they originate from very different species.

Human and sperm whale myoglobin have very similar primary structures. Which of the following statements are correct?

A) Statements 1 and 2 are correct.

B) Statements 1, 2, and 4 are correct.

C) Statements 1, 2, and 3 are correct.

D) All of the listed statements are correct.

A) Statements 1 and 2 are correct.

Explanation:

As the Human and sperm whale myoglobin  are very likely related evolutionarily hence option a is correct.

The differences in the sequences in many instances represent a conservative change (such as L for I) hence option b is also correct.

While all the other options are not correct.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
