This is a biome.

Biomes really do cover large areas, for example there is one biome stretching from France to central Russia (temperate broadleaf forrest). They are characterized by a similar soil and a shared community of animals and plants.

Some amino acids are both glucogenic and ketogenic. Explain the difference between the two types and why some amino acids can be
vesna_86 [32]

Answer:

From the point of view of the type of molecule that is obtained after the degradation of the hydrocarbon skeleton, amino acids can be classified as: glucogenic and ketogenic. The main difference between glucogenic amino acids and ketogenic amino acids is that glucogenic amino acids can be converted to pyruvate or other glucose precursors, while ketogenic amino acids can be converted to acetyl CoA and acetoacetylCoA.

Explanation:

Glucogenic amino acids are amino acids that break down to pyruvate, alpha-ketoglutarate, succinyl Co-A, fumarate, and oxaloacetate and are so named because the synthesis of glucose from these molecules is feasible. Both pyruvate and the Krebs cycle intermediates noted above can be converted to phosphoenolpyruvate and subsequently glucose through gluconeogenesis.Ketogenic amino acids are the amino acids that generate acetyl-CoA or acetacetyl-CoA and are called by this name because they can cause ketone bodies. Since mammals lack the proper enzyme system, these compounds can never be used as precursors for glucose biosynthesis. Of the twenty universal amino acids, fourteen are purely glucogenic and two are purely ketogenic (leucine and lysine). The remaining four (isoleucine, phenylalanine, tryptophan and tyrosine) are glucogenic and ketogenic simultaneously since a part of the hydrocarbon skeleton originates precursors for the biosynthesis of glucose (pyruvate or Krebs cycle intermediates) and the other part acetyl-CoA or acetacetyl -CoA.

Answer: The two species were Rhesus monkey and Human <span>
Hemoglobin protein is the iron containing protein found in the red blood cells which function by transporting oxygen through the blood stream from from the lungs to the tissues and it is important for survival. However, the  two species that have similar amino acids in the hemoglobin protein were Rhesus monkey and Human because they were not far from others.</span>

Explanation:

AAC GGC AAA CGA TTG ---> ACG GGC AA? CGA TTG

The bolded portion represents where the mutation occured.

As you can see the nitrogenous base adenine was completely removed from the codon

When a nitrogenous base gets removed it is known as a <u>deletion </u><u>mutation</u>
