What type of mutation occurs when a nucleotide is added to the DNA?
Yanka [14]

Answer:

A frameshift mutation.

Explanation:

A frameshift mutation is when one adds an extra nucleotide to a series of nucleotides. This will mess up the order of the nucleotide, thus when it forms the codons, and eventually, the amino acids; all of the codons are wrong, thus all of the amino acids are wrong.

In this situation, an extra nucleotide is added to a sequence of DNA, this results in all of the other nucleotides getting pushed over by (1). Thus, all of the nucleotides form the wrong codons and the wrong amino acids. Therefore, a frameshift mutation has occured.

A scientist was observing a specimen under a microscope. He obtained the specimen from pond water. He observed that the specimen
NNADVOKAT [17]

There are three ways you can solve this problem:

1.- You can guide yourself through knowledge, and therefore know the answer. There isn´t much to explain here.

2.- You can eliminate obvious options such as sarcodina or apicomplexa. Euglenoid isn´t an extremely obvious removal since it has a flagela, which can be mistook by a hairy-structure. But, if you do things correctly, obtaining your answer wont be a problem.

3.- You can do an etymologic-guess, which works really well in biology. If you guide yourself this way, you´ll bump into the answer quickly --> "cilio" means hair and according to the description the specimen was covered in hairy structures.

Hope it helped,

How do ATP and NAPH connect light dependent and light independent reactions in photosynthesis​
Finger [1]

Answer:

In plants photosynthesis occurs in two steps light-dependent stage and light-independent stage.

ATP is energy carrier and NADPH is electron carrier and both are produced during the first step from the sunlight as they carry the energy and electron to the next step which is light-independent step. In this step both ATP and NADPH are used in the formation of sugars from carbohydrates.

Therefore, these molecules connect the light-dependent and light- independent reactions of photosynthesis.

Which buffer system is closely linked to the respiratory system?A. pyruvateB. bicarbonateC. phosphateD. protein
Alchen [17]

B. Bicarbonate

<em>The blood brings bicarbonate to the lungs, and then it is exhaled as carbon dioxide. The kidneys also help regulate bicarbonate... it is excreted and reabsorbed by the kidneys.</em>

<em>The body's main response is to get rid of more carbonic acid and hold on to as much bicarbonate base in the kidneys as it can.</em>
