A. They develop from the same embryonic
tissue.
Human
Bird
B. They are the most important sets of
bones.
C. They have no current use.
D. These animals do not share a common
ancestor.
Answers
Answer: its A
Explanation:
They have no current use, because they were passed down from a common ancestor, homologous structures are those that are comparable in related organisms, hence option C is correct.
What is homologous structures?The descendants of these structures may or may not carry out the same purpose. Tetrapods' four limbs are an illustration of homologous features. All four limbs are present in birds, bats, mice, and crocodiles.
Bony fish such as sharks do not. Tetrapods evolved four limbs, and their descendants have carried on this trait.
As a result, the presence of four limbs is a homology. The upper arm of both humans and cats consists of just one bone, which we refer to as the humerus, and two forearm bones, the radius on the more medial side and the ulna on the more lateral side.
Therefore, option C is correct.

A student wanted to see if covering a leaf in foil would stop it from producing starch. Why should the student put the plant in a dark cupboard for 48 hours before returning it to the light and starting the experiment?
1. To make the results reliable
2. So that the plant would photosynthesise faster when returned to the light
3. So that any starch already in the leaf was used up by the plant
4. He did that simply
Answers
Answer:
4.) He did that simply
Explanation:
I'm just guessing it's 1 because the other answers don't seem reasonable
Answer:
Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to the consumption of all stored starch making the leaf starchless. The correct answer is option D.

White tailed deer begin their reproductive cycle in the fall. Rising testosterone levels in
male white tailed deer cause them to start their breeding season around the same
time. Offspring are born the following spring and summer.
What is the most likely explanation for the white-tailed deer having a seasonal
breeding cycle instead of a monthly breeding cycle?
Answers
The explanation for the white-tailed deer having a seasonal breeding cycle should be that deer provide birth in the spring and summer.
What is seasonal breeding?It is considered to be animal species so it should be successfully mated at the time of specific times of the year. It permits the optimization of survival of young because of factors like food, water availability, etc
So, here deer provide birth in the spring and summer for avoiding the pregnancy at the time of hot summer months.

Number 1 is hypo tonic because solute is going into the cell. The cell is getting bigger and expanding. You can think of Hypotonic as getting bigger by using Hypo which can be Hippo. Hippos grow bigger over time.
Number 2 is Isotonic. The water is going in and out at the same rate. Therefore, nothing really changes here.

Which nitrogenous base would pair with adenine during DNA replication?
A
O cytosine
<
B
O guanine
C
Othymine
D
ouracil
Answers
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).
The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.
What are nitrogenous base?
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules and adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G). 18% became cytosine pairs with G. A pairs with T. T and C are not complementary base pairs, but we know that if molecules consists of 32% T, it must have 32%.
The discovery of the structure of DNA was useful because it revealed how mRNA was used to make proteins. There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.
HDL stands for high-density lipoprotein or good cholesterol which absord cholesterol and send it to lever. The lever then flushes it from the body. High-density lipoprotein can lower your risk for heart disease and stroke.
Therefore, The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.
