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.
Considering the following;
I. Heat is not readily available to all living cells.
II. Heat at excessive amounts denatures proteins.
III. Heat does not provide the activation energy for their reactions.
IV. When a critical temperature is reached, proteins no longer function
Answer;
I and IV
Explanation;
Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.
Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.
Megasporangium tissue gives rise to the female gametophyte.
<h3>What is the name of the diploid tissue that gives rise to the female gametophyte?</h3>
- Three of the four haploid megaspores worsen into antipodal cells interior the female gametophyte.
- The central cell of the female gametophyte contains two cores that when fertilized gotten to be the endosperm.
- Megasporogenesis alludes to the advancement of megaspores from the megasporocyte, the cell that experiences meiosis.
- Meiosis of the megasporocyte core comes about within the arrangement of four haploid megaspore cores.
- In most taxa, meiosis is taken after by cytokinesis, coming about in four megaspore cells.
- This design is named monosporic megasporogene - sis; since of the four megaspores delivered, as it were one of them contributes to the female gametophyte

Answer:
The chemical components, which are utilized to eradicate or eliminate pathogenic microbes are known as chemical disinfectants. These comprise sodium hypochlorite, chlorine, bromine, hydrogen peroxide, chloramines, and others.
Traditionally, the chemical disinfectants are usually compared with phenol as phenol was the first or the foremost used chemical agent for the purpose.
