Answer:
elliptical (nearly circular)
Explanation:
According to Kepler's laws of planetary motion, the planets do not revolve around the Sun in exact circular orbits. The path of the planet or any other body in the solar system is elliptical, with the Sun at one of the foci. Though, the eccentricity is not large, so one can say, the path of the planets and the asteroids around the Sun is nearly circular.
The genotype of the mother must be heterozygous.
<h3>Punnet' square</h3>
In order to obtain a probability of 25% red-eyed males from the offspring, the mother must be heterozygous for the trait. The father can be of any genotype.
Thus, the likely genotype combination that will result in 25% red-eyed males are:
x 
and 
When you cross the first one above, the genotype of the offspring would be
.
The second cross will give offspring with the genotypes 
Both crosses give a 25% chance of producing re-eye males.

<h3>
What is a Phenotype?</h3>
The phenotype is the set of observable characteristics or traits of an organism.
The term phenotype covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.
Phenotype can also refers to an individual's observable traits, such as height, eye color and blood type.
To determine a phenotypic ratio, we look at the alleles of the parent organisms and estimate how often those genes will be exhibited by the offspring. Most times, we know what the alleles will express and how they will look.

Answer:
True
Explanation:
Bacteria generate toxins which can be classified as either exotoxins or endotoxins. Exotoxins are generated and actively secreted; endotoxins remain part of the bacteria. Usually, an endotoxin is part of the bacterial outer membrane, and it is not released until the bacterium is killed by the immune system.Most viral infections eventually result in the death of the host cell. The causes of death include cell lysis, alterations to the cell's surface membrane and various modes of programmed cell death. Some viruses cause no apparent changes to the infected cell.
