Answer: Option A
Explanation:
The heterozygous allele can be defined as the condition in which the organism has two different alleles of the gene.
It is represented as Rr, means a capital letter and a small letter. This hows that the organism has one dominant gene and one recessive gene in it.
This dominant and recessive condition decides the genotype and phenotype of organism.
Answer:
Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane. Organisms that have eukaryotic cells include protozoa, fungi, plants and animals.

A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).

The Equator is halfway in between
During glycolysis, the source of the chemical energy that is captured in ATP:
B. the chemical bonds in glucose
Explanation:
- Glycolysis is also known as Embden-meyerhof pathway.
- It is an oxidative process in which one mole of glucose is partially oxidized into two moles of pyruvate.
- Glycolysis occurs in the cytosol of the cell in both aerobic and anaerobic conditions.
- The breakdown of six-carbon glucose into two molecules the three-carbon pyruvate occurs in ten steps.
- The first five steps of this pathway constitute the preparatory phase.This phase consumes energy during the phosphorylation of glucose.
- The preparatory phase produces two molecules of glyceraldehyde 3-phosphate (G3P).
- The two molecules of G3P are then converted to pyruvate in the next five steps that constitute the payoff phase.
- The energy gain of glycolysis comes in this payoff phase.
- The oxidation of G3P yields a high energy molegule 1,3 -bisphosphoglycerate .
- The high energy phosphate on carbon 1 of this molecule is donated to ADP and ATP is produced.
- This synthesis of ATP is called substrate level phosphorylation because ADP phosphorylation is coupled with exergonic breakdown of a high-energy bond.
