Answer:

B (By preserving the habitat)

Explanation:

Option B refers to preserving the habitat, which is an action that someone could take to increase the cheetah population because it would lead to cheetahs having more places to live, grow, and breed. The other options all produce negative outcomes for cheetahs.

Where could the instructions be held to create a protein?
FromTheMoon [43]

Answer:

The correct answer is - in DNA molecules.

Explanation:

The instructions or the information for the creation of the protein is held in the DNA molecule inside the nucleus in eukaryotic organisms while present in the cytoplasm in prokaryotes.

The DNA molecule has coded all the information for the particular protein by the two processes transcription and translation. Transcription is the first step which makes a copy of the DNA is complementary in the form of mRNA, The second step involves the decoding mRNA into an amino acid chain with the help of ribosomes.

Amino acid catabolism involves the breakdown of 20 amino acids all of which contain nitrogen but have different carbon skeletons
Alex Ar [27]

Answer:

The overall strategy employed in the catabolism of the carbon skeletons of the 20 amino acids is conversion to citric acid intermediates such as acetyl-CoA

Explanation:

The breakdown of the  different carbon skeletons of the 20 amino acids is strategically channelled  towards the citric acid cycle. Six major products are obtained in the catabolism of the carbon chain of amino acids and these products all enter the citrc acid cycle. The six major products are acetyl-CoA, α-ketoglutarate, succinyl-CoA, fumarate, oxaloacetate and pyruvate.

The amino acids that are broken down completely into acetoacetyl-CoA and/or acetyl-CoA are said to be ketogenic since they yield ketone bodies in the liver.

The amino acids that are broken down into α-ketoglutarate, succinyl-CoA, fumarate, oxaloacetate and pyruvate can be converted to glucose and glycogen and are said to be glucogenic. Pyruvate can further be converted to either acetyl-CoA or oxaloacetate. Some amino acids though are both ketogenic and glucogenic, e.g. tryptophan, threonine.

Fill in the blank with the appropriate term. 1.The___________ is often considered to be the cell's control center. 2.The________
ValentinkaMS [17]
 1.The nucleus is often considered to be the cell's control center.
(because it contains the DNA)

2.The cytoplasm consists of everything inside the plasma membrane of the cell.
(actually it excludes the nucleus)

 3.The plasma membrane forms a boundary between the inside and outside of the cell. - it controls what can enter and what can't!


4.The cytoskeleton is essentially a "skeleton" inside the cell..
it maintains the form of the cell

5.The rough endoplasmic reticulum is covered with
Ribosomes -they make the proteins!


6.Lysosomes use enzymes to break down foreign matter and dead cells.

 7.plant cells cells specifically have a cell wall, a large central vacuole, and chloroplasts.-choloplasts are only found in plants!

The distance versus time graph for Object A and Object B are shown.
Ksivusya [100]

Answer:

The correct answer is - Both move with constant speed.

Explanation:

If an object moves in a particular way that it covers the same distance at the same times the speed considered as constant suppose if two objects a and b both travel 10 m and 20 m respectively and the time they take in travel are 2 and 4 seconds respectively than we can say they both have a constant speed.

The relation between the variables x,t, and v is

x=v.t

If V is constant which is the speed we get a straight line x-t in the graph.

By the given information we can say that both objects A and B are traveling at a constant speed.
