Technically viruses are not living as they do not contain any of the membrane bound organelles (mitochondrion) as well as ribosomes, which are present in cellular life forms; viruses contain nucleic acid (either DNA or RNA). All antibiotics invariably act by interfering with the prokaryotic 70S ribosomes during protein synthesis; but antibiotic has no effect on the eukayotic 80S ribosomes. So during viral infection, when person’s general immunity is low they are prone to infection by prokaryotic organisms (eg Staphylococcus aureus); a course of treatment with antibiotics kills the infecting bacterium, unless it happens to be resistant to that antibiotics – eg Methicillin-resistant Staphylococcus aureus, (MRSA) a common hospital bug.

In a maternity ward, four babies become accidentally mixed up. The ABO blood types of the four babies are known to be. Baby Jane
nydimaria [60]

Answer:

See explanation

Explanation:

We inherit our blood groups from both parents. Our blood type is controlled by a single gene. This gene displays 3 different allelic pairs which must include A, B or O.  A child is expected to receive one of the three possible allelic pairs from each of the both parents. This means that there are six possible genotype and four possible phenotype for the child.

Given that Christopher's parents (Andersons) are AB and O,Christopher can have a B blood group.

Given that John's parents (Browns) are A and O, it explains how John can have blood group A.

Given that The Christiansons are A and AB, they can give birth to Robin whose blood group is AB.

Since the Dietrichs are O and O, the only possible blood group of their child is O, hence they are definitely the parents of Jane.

DIA [1.3K]

Answer:

Null Hypothesis -

The observed frequency is approximately equal to the expected frequency of phenotype.

Explanation:

Pure Breeding Cross - TTww x ttWW

Genotype of offspring in F2 generation - TtWw

Null Hypothesis -

The observed frequency is approximately equal to the expected frequency of phenotype.

The chi square analysis is attached

The degree of freedom for this question is 3

The p value for X^2 estimated through chi square test is 0.5

Hence the null hypothesis is accepted.
