Run more trials for the experiment to ensure that the small difference is not significant. B
Answer:
A. Where does sugar enter the blood?
After eating food, in the intestine the glucosa is absorbed by an SGLT1 cotransporter who releases it to the bloodstream.
B. How can you tell where sugar enters the blood?
Making an analysis of its high concentration in the epithelial cells of the intestine
C. Where is sugar removed from the blood?
After traveling through the blood flow, the sugar enters the cells of the body that require it, for example, muscle cells. Excess glucose in the blood is removed by the kidney through urine.
D. How can you tell?
The filtration of glucose by the kidneys can be verified by an analysis of their co-concentrations in these renal cells and Medical tests of the urine sample.
The choices are as follows:
a) survive better in aquatic environments b) grow more quickly c) reproduce more quickly d) colonize land<span>.

I think the answer is option D. <span>Cuticle, stomata, and vascular tissue are all key adaptations enabling land plants to colonize land. Hope this answers the question. Have a nice day.</span>
Answer 1: Option C, heterozygous dominant
Explanation: For example the genotypes of these true breeding white and purple flowers is pp and PP, respectively, then the offsprings would be all Pp. This is a heterozygous genotype and it will express dominant trait only.
Answer 2: Option C, homozygous recessive
Explanation: If the trait is recessive, then it will express only when both the alleles of the genotype are recessive alleles. And this would be homozygous state. For example, 'pp' would be the genotype for white flowers.
Answer 3: Option D, white and red
Explanation: If we want that all offsprings should be heterozygous, then parents should be true breeding, which means homozygous. Here, roan is a heterozygous trait [WR]. So both parents should be homozygous, like RR and WW. Then only all offsprings would be heterozygous.
