Answer:

The term complementary means "matching" in base-pairing

Explanation:

What I mean by this is that each base has its complementary (matching) base.

For example, cytosine goes with guanine so the complementary base of cytosine would be guanine.

The complementary base of thymine would be adenine

Answer:

From The School of Biomedical Sciences Wiki. Complementary base pairing is the phenomenon where in DNA guanine always hydrogen bonds to cytosine and adenine always binds to thymine. The bond between guanine and cytosine shares three hydrogen bonds compared to the A-T bond which always shares two hydrogen bonds.

experimental evidence shows that the process of glycolysis is present and virtually identical in organisms from all three domain
puteri [66]

The question is incomplete as it lacks the multiple options. The multiple options are as follows:

a. Across the three domains, all organisms depend solely on the process of anaerobic respiration for ATP production .

b. Glycolysis is a universal energy-releasing process and therefore suggests a common ancestor for all forms of life .

c. The existence of glycolysis as an energy-releasing process in all organisms suggests that convergent evolution occurred .

d. All organisms carry out glycolysis in mitochondria.

Answer:

Option (b).

Explanation:

The three main domains of life are prokarya, eukarya and archaea. The archaea and eukarya are more closely related with each other than the prokarya.

The glycolysis is the process of breakdown of glucose molecule to generate ATP. The glycolysis is the most common process of the generation of the ATP are present in almost all the organisms whether the organisms is ancestral or modern.  

Thus, the correct answer is option (b).

What would happen if your heart valves stopped working?
LiRa [457]

Answer:

In heart valve disease, one or more of the valves in your heart doesn't work properly. Your heart has four valves that keep blood flowing in the correct direction. In some cases, one or more of the valves don't open or close properly. This can cause the blood flow through your heart to your body to be disrupted.
