Answer:
All of these are correct.
Explanation:
Immune system, reproductive system and nervous system are adversely affected by the contact of highly toxic chemicals because toxic chemicals have materials which is harmful for the cells that the cause of cell death or damaged the structure of the cell due to which the cell can't perform its function efficiently. All the system i.e. Immune system, reproductive system and nervous system are made up of cells so if the cells are damaged by these toxic chemicals the body systems are also negatively affected.

The answer is sunlight, chlorophyll, carbon dioxide and water.
In the photosynthesis plants use sunlight as an energy and convert it into chemical energy stored in carbohydrates. Carbon dioxide and water are used for carbohydrate synthesis. This process occurs in the chloroplasts containing chlorophyll, which is necessary for absorbing energy from sunlight.
Flagella provide motility to a sperm cell, cilia act as sensory "antennae" in many cells and microvilli Increase a cell surface area
<h3>What is flagella, cilia and microvilli?</h3>
Flagella is a hair-like structure used by cells for locomotion or movement. The sperm makes use of flagella for locomotion.
Cilia is a hair-like structure that is found on the surface of organisms which are sensitive to touch.
Microvilli is a hair-like structure that is richly fortified with blood vessels found in areas for absorption. This is because it increases the surface area.

<span>You need to create Punnet square. Since there are four gene sequence from each parent, there are 24 =16 alternatives.
List the various combinations in which the alleles can sort. For the first parent, each p allele can sort with each t allele, so the combinations which involve the P allele are P T1 and P T2 (where the T allele on one chromosome is denoted T1 and the T allele on the other is denoted T2).
The combinations which involve the other p allele are p T1 and pT2. For the second parent, p1 denotes the p allele on one chromosome and p2 denotes the p allele on the second. The possible combinations are p1 T, p1 t, p2 T and p2 t. You line these up on the sides of the grid, do the cross, and look at the frequency at which the different genotypes (and phenotypes) arise to analyze the cross
.If you do a Punnett square based on the gametes of this cross -PT and pT for the first parent and pT and pt for the second parent- the phenotype for this cross would be 2 Purple tall : 2 White tall which means the offsprings would be 50% purple tall and 50% white tall. Two of the offsprings in this cross will have the parental genotypes ,one will be heterozygous for both traits(PpTt) and the fourth offspring will have the genotype ppTT. and so... it is Tt n Pp..</span>
