IrinaK [193]

Answer:

a gas produced during photosynthesis

Explanation:

during photosynthesis plants use carbon dioxide, water and sunlight to make sugar (glucose) and a waste product, oxygen gas.

the equation of this process can be:

6 CO2 + 6 H2O + light energy  →  C6H12O6 + 6 O2.  

carbon dioxide + water + light  →   glucose + oxygen

Jill is heterozygous for gene A and is going to have a child with Jack, who is homozygous recessive for gene A. Which of the fol
Igoryamba

Answer:

D. Aa

Explanation:

Given:

Jill (mother) is heterozygous for gene A --------- i.e Jill = Aa

Jack (father) who is homozygous recessive for gene A-------- i.e Jack = aa

Now if both cross and fertilization occurs, we have:

         A          a

a        Aa        aa

a        Aa        aa

The offsprings are (Aa, Aa, aa, aa)

Nondsijunction is the inability of homologous chromosomes to seperate properly during cell division. Now, we were told that this fertilization undergone nondisjunction in meiosis 1. Hence, both homologous chromosome move into the same daughter cells instead of different daughter cells because separation of homologous chromosome does not occur properly.

Therefore the result of these fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis yields offspring with genotype Aa of their Mother (Jill).

Antigen presenting cell is a cell phagocytizes an antigen and displays fragments of it on its surface for recognition by other cells of the immune system

<h3>What is Antigen presenting cells?</h3>

An antigen-presenting cell refer to an immune cell that detects, engulfs, and pass a message to the adaptive immune response about an infection. When a pathogen is detected, the antigen presenting cells will engulf the pathogen and digest it to form many different fragments of the antigen.

Therefore, Antigen presenting cell is a cell phagocytizes an antigen and displays fragments of it on its surface for recognition by other cells of the immune system
