As plates move past each other, stress builds up. What happens when this stress becomes too much?
aksik [14]

Answer:

The rough edges of the plates get trapped on each other as they pass. This slows the motion on the border as the remaining plates continue to move. Pressure builds up, and when the plates get too much, the hard, fractured lithosphere breaks unexpectedly, possibly resulting in an earthquake.

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.

During which phase do the chromosomes make copies of themselves so that there are two of each one?
SashulF [63]

Answer:

The beginning and majority of the time is known as Interphase. Interphase is 80% of the total cycle and is where the cell does most of the work in replicating organelles, chromosomes, and preparing to undergo Mitosis which is the actual splitting process where one cell becomes two. During Interphase there are 3 major steps, G1, S, and the G2 phase.
