The correct answer is  (a).

Both L-D and L-IND reactions take place in the chloroplast of the cell but in different parts or locations. L-D reactions take place in the chloroplast thylakoids while L-IND reactions take place in the chloroplast stroma.

Chloroplasts are chlorophyll- filled organelles mostly found in the leaves of green plants.  Chloroplasts are surrounded by a double membrane called the thykaloid membrane that forms long folds within the organelle. In electron micrographs, the thykaloid membranes look like stacked coins. Chlorophyll is located within the thykaloid membranes.

Between the thykaloid  membrane and the chloroplast membrane is a space. This space is what is called the stroma.

What is this an example of:
Karolina [17]

Answer:

A) a cow who's coat color is roan (red and white) : Co- dominance

B) A red flower and a white flower produce a pink flower: Incomplete dominance

C) In rabbits there are 4 different versions of the gene for coat color- Multiple alleles

Explanation:

Co-dominance can be described as a phenomenon in which the two different phenotypes of the parents can be seen in the offspring produced by them. For example, In the option A, the cow had a parent with red coat colour and a parent with a white coat colour. Both these traits were seen in the offspring.

Incomplete dominance is a phenomenon in which parents of two different phenotypes give rise to a new phenotype in the offspring which is not present in both of the parents.

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.

You are less likely to see a total solar eclipse than a total lunar eclipse because
sergejj [24]
Lunar eclipses are more wildly visible because Earth casts a much larger shadow on the moon during a lunar eclipse than the moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar!. ;)

What process must metamorphic rocks undergo to become igneous rocks? (metamorphic rocks + ? = igneous rocks)
