<h2>Option (B) is Right Answer</h2>

Explanation:

 (b) Oxidize pyruvate to acetyl-CoA.

  • <em>The oxidative decarboxylation of Pyruvate to form Acetyl-CoA</em> is the connection among <em>Glycolysis and the Citric acid cycle</em>
  • It is an irreversible oxidation process in which the <em>carboxyl group</em> is expelled from pyruvate as an atom of CO2 and the <em>two residual carbons become the acetyl group of Acetyl-CoA </em>
  • Pyruvate can be changed over into sugars by means of <em>gluconeogenesis, </em>to unsaturated fats or energy through <em>acetyl-CoA, to the amino acid alanine, and to ethanol</em>

If DNA can’t leave the nucleus, how do you think the DNA instructions get to the ribosomes in the cytoplasm?
koban [17]

Instructions in the DNA are first transcribed to RNA and the RNA is transported to the ribosome in the cytoplasm.

<h3>Transcription</h3>

Transcription is a process whereby the genetic instructions in the DNA of organisms are transcribed to RNA in the nucleus.

After transcription, the RNA which now carries the genetic codes is transported to the cytoplasm where it gets attached to the ribosome before the genetic codes are translated to their respective amino acids.

A horticulturalist wants to produce geraniums with specific characteristics. She knows that the trait of red flowers is governed
likoan [24]
<span>The answer is  A -The red geranium is heterozygous for red flowers (Rr).

We know that the red flower, to be red needs to have at least a dominant allele, so it could be either Rr or RR.
Let's try both scenarios.
If the white</span><span> geranium (rr) is being crossed with RR, all the offspring would be red with genotype: Rr.
On the other hand, if the flower is Rr and it's being crossed with rr, that would result in </span><span>half of the new generation plants having red flowers and the other half white flowers.</span>

Which molecules are needed to cut and copy segments of DNA?
klio [65]
(1) reproductive hormones
(2) carbohydrates
(3) antibodies
(4) biological catalysts


Answer and Explanation:
All of the answer choices are molecules in our body. Let's look at the definition of each choice one at a time. Reproductive hormones such as testosterone and estrogen function to regulate reproductive functions such as menstrual cycle, sperm production etc.
Carbohydrates are molecules from which our bodies derive energy in the form of ATP.
Antibodies protect our bodies from the invasion of foreign particles (pathogens)
Biological catalysts, or enzymes help our body speed up and perform all of the reactions that need to be done such as cutting and copying DNA. Therefore, choice (4) is the correct answer choice.
