BRAINLIESTTTT ASAP!!!
Irina-Kira [14]
Cellular respiration in algae, as in all organisms, is the process by which food molecules are metabolized to obtain chemical energy for the cell. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.<span>

Prokaryotic DNA is enclosed within a nucleus, while eukaryotic DNA is not.<br>O True<br>O False​
blagie [28]

Answer:

False

Explanation:

Prokaryotes do not have a nucleus.

This means their DNA is not enclosed in a nucleus and instead is in the cytoplasm.

What did the Watson-Crick model suggest about the replication of DNA?
Setler [38]

Answer:

c. If the double helix were unwound, each nucleotide along the two parent strands would form a hydrogen bond with its complementary nucleotide.

Explanation:

According to the Watson-Crick model, two DNA strands are held together by complementary base pairing wherein each nucleotide of one DNA strand forms hydrogen bonds with its complementary nucleotide present in the other strand. During DNA replication, two DNA strands are separated by the action of helicases enzymes.

The separated DNA strands serve as a template for DNA replication. Here, each nucleotide of the template DNA strand binds to its complementary nucleotide by hydrogen bonds. For example, adenine of the template strand forms two hydrogen bonds with thymine while guanine forms three hydrogen bonds with cytosine.
