RrXtXt×RrXTY is representing the cross between the white eyed female and red eyed male.
Option D
<h3><u>Explanation:</u></h3>
The genes that are discussed here both are completely dominant over their recessive alleles. In the autosome, the dominant R gene is responsible for red eye and recessive r gene is responsible for sepia eye. But in allosome, the dominant T gene allows the eye colour to be expressed and the recessive t gene doesn't allow eye colour to be expressed and makes it white.
As the female do have 2 X chromosomes and the female is white eyed, then both the chromosomes of female have t gene.
As the male is red eyed and have one X chromosome, so the male must have atleast one R gene in autosome to make the eye colour red and must have T gene in his X chromosome to make it appear in phenotype.
So the most possible cross that is given here is RrXtXt×RrXTY.
Photosynthesis takes place in the chloroplast of the plant cell.
Deforestation encourages flooding by allowing water to run off into streams
<u>Explanation</u>:
Deforestation plays vital roles in the flooding. The roots of the Trees prevent sediment runoffs and forests hold more water than farms or grasslands.Firstly the leaves in the trees will capture some amounts of water which will be eventually evaporated. Secondly, some quantity of water is absorbed by the tree's roots. Also,Tree roots hold the soil in place, reducing the movement of sediment that can shrink river channels downstream..
The process of deforestation will lead to dislodging of the topsoil. this makes the topsoil unstable and reduces its capacity to hold down the water
A polypeptide is a chain of amino acids. The completed polypeptide chains come together to form proteins, so be careful not to get them mixed up!
Hope this helps!
