An intact length of dna consists of 320 total nucleotides (160 nucleotides/strands). a total of 95 cytosine nitrogen bases are f

Answer:

65

Explanation:

The DNA segment has a total 95 cytosine bases. Since cytosine makes hydrogen bonds with guanine base, this means that the DNA segment has a total 95 guanine bases.

Total guanine + cytosine bases in the segment= 95 + 95 = 190

So, a total of adenine and thymine bases in the DNA segment= 320-190 = 130

Since the number of adenine and thymine bases are equal in a double-stranded DNA molecule, the number of adenine bases in the given segment would be= 130/2= 65

1) B
    (I'm not so sure of this one) All of the other options have a steady impact on population regardless of the density of organisms except competition

2) D
    Increased carbon dioxide levels would not hinder plant growth, and tsunamis aren't really linked to carbon dioxide levels. Increased carbon dioxide is unlikely to lower the air temperature so only D is left.

3) A

4) Three properties of water that allow it to sustain life are that it is adhesive, it is a good solvent, and cohesion. Adhesion is important in situations such as water travelling up xylem tubes in plants so that the water is not pulled down by gravity and can reach parts of the plant that need water. Cohesion allows the water being pulled up the xylem to stay together and for water molecules to be pulled when a neighbouring one is moved. Water being a good solvent allows inorganic minerals to be taken with water through vascular tissue, such as in the previous example.

The masses of all the substances either used up or formed during photosynthesis are shown below: A = 192 grams, B = 108 grams, C
qwelly [4]

Answer:

B.) The total mass of B and C, which are water and carbon dioxide, is equal to the total mass of A and D, which are oxygen and glucose.

Explanation:

The following statements that support the conclusion that photosynthesis follows the law of conservation would be B.) The total mass of B and C, which are water and carbon dioxide, is equal to the total mass of A and D, which are oxygen and glucose. We can conclude this because the law of conservation states that for any transfer of mass, it will always stay the same, meaning that you cannot add to it nor remove from it. Option A would not be correct because the question asked about photosynthesis, and A is describing cellular respiration. Options C and D would also not be correct because when you add up the values in the way that they are listed, it does not sum up to the statement. Here are all of the letter combinations added together, based on the letter choices:

B and C ➡ 372

A and D ➡ 372

A and B ➡ 300

C and D ➡ 444

A and C ➡ 456

B and D ➡ 288

Notice how the first two listed add up to 372. And because this matches option B, that will be your answer.
