Answer:

The correct answer is option 3. "Ab and aB".

Explanation:

Crossing over of two chromosomes, or chromosomal crossover, is the exchange of genetic material between two homologous chromosomes. This genetic process is responsible for the genetic variations that occurs during sexual reproduction. Usually crossing over occurrs between matching genetic sequences, therefore a diploid invidual with an AB allele that crosses over with an invidual with ab allele will exchange each allele in equal parts. The resulting chromosomes will be Ab and aB, one part per allele.

A certain area received a large amount of rain and some of it remained on top of the soil. What happened to the rest of this wat
ValentinkaMS [17]

In the large rainfall is some water remains in the top of the soil the rest of this water is seeped into the ground.

<u>Explanation:</u>

  • Mainly the absorption of water by the ground depends upon the nature and the fertility of the soil.  
  • When the ground receives the water it mainly accounts for the absorption and then there will be a runoff. The absorption helps to raise the level of groundwater for future usage.
  • The amount of water that can get into the soil mainly depends upon the permeability of the soil surface. The water which can't infiltrate in the soil runs off into the water bodies.  
  • The water is an essential requirement for survival and the existence of biological organisms.

What is base ? what is acid and salts? plz explantion this question
Dvinal [7]

Explanation:

In acid – base chemistry, salts are ionic compounds that result from the neutralization reaction of an acid and a base. Basic salts contain the conjugate base of a weak acid, so when they dissolve in water, they react with water to yield a solution with pH greater than 7.0.
