<span>The feature that would distinguish euglena from cyanobacteria is the
membrane-bound nucleus.</span> Also, cyanobacteria do not have
flagella, while euglena does. Cyanobacteria is a prokaryotic organism and thus, doesn’t have a nucleus, but unlike heterotrophic prokaryotes, cyanobacteria have internal membranes (thylakoids).
<span>Euglena is a eukaryotic organism which contains chloroplast for the photosynthesis.</span>
Answer: Natural selection can act on traits determined by alternative alleles of a single gene ... hope this helps, this is one of many answers for this question!
Fluids, water, You loose salt water and electrolights when you perspire, when you drink water it doesn't have salt or electrolights it just has water so it can only replace your water
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.
