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.
Answer:
Osmosis helps cells maintain homeostasis because a cell needs to maintain a specific water balance so that chemical reactions can take place. Osmosis can also be used to balance out the concentration of other molecules (such as sugar or salt) present on either side of a cell membrane.
Explanation:
Homeostasis is the ability of a system to regulate its internal environment through maintaining a stable, relatively constant set of properties such as temperature and PH. Key Terms homeostasis : The ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium, such as the ability of warm-blooded.

In the absence of competition, P. aurelia grew better than P. caudatum. Every daythere were more P. aurelia than<span>P. caudatum</span>
so what's the question here??
