Answer:
A and E
Explanation:
<em>Listeria monocytogenes</em> is a Gram-positive bacterium, mobile by means of flagella. CANNOT form capsules and / or endospores; It is a pathogenic bacterium, normally present in the environment. It is capable of living both in the soil and in the cytosol of a eukaryotic cell.
<em>L. monocytogenes</em> can enter host cells through endocytosis, this phagocytic vacuole is rapidly lysed by the listeriolysin O (LLO) toxin produced by the bacteria. Once free in the cytosol, it expresses the genes to acquire the necessary nutrients for intracellular multiplication and spread between cells and this is precisely what allows it to evade the humoral immune response.
Answer:
Mr. Smith is not justified, Mrs. Smith can not be blamed necessarily for being unfaithful
Explanation:
Widow's peak is a dominant trait which means that it will be expressed both in homozygous and heterozygous condition. If "A" is the dominant allele and "a" is the recessive allele, the trait can be represented as AA or Aa.
Both Mr. Smith and Mrs. smith expressed the trait so they can either have AA or Aa genotype. If even one of them had AA genotype all the offspring would have the trait. But if both of them are heterozygous for it:
A a
A AA Aa
a Aa aa
There is 75 % probability of the child to have the trait (AA or Aa) but there is also 25% probability that the child does not express the trait (aa). Their second child belongs to this category and hence Mrs. Smith can not be blamed for being unfaithful.

Near sightedness is a condition whereby the eyeball is too long or cornea has excess curvature such that light entering the eye is focused in front of the retina rather on the retina itself.
The exact cause of nearsightedness is unknown but there are two factors that may be responsible for its development.
1. Visual stress
2. Heredity
Individuals who spend considerable time reading or working at a computer or engage in other types of intense close visual work may develop nearsightedness.
There is credible evidence that many people inherit nearsightedness or are at least predisposed to the condition, especially if both parents suffer from the condition.
Far sightedness (hyperopia) is a condition where the eye is shorter than normal, the cornea is not curved quite enough or the lens sits further back in the eye than is normal.
This condition can be inherited especially if both parents suffer from it.
The other cause is through diseases like diabetes or glaucoma.
