Biology
1 answer:
ladessa [460]3 years ago

Answer:

The structure of each cell type's wall.

Explanation:

The basis of Gram stain is differentiating cells in two different categories depending on the composition of the cell wall. Gram positives fixate a KI and Crystal Violeta complex in their peptidoglycan wall, but otherwise, gram negatives don't have a thick layer of this, and therefore, when the wash process happens it takes away all the pigments leaving the cells blank for the last pigment (pink).

Amiraneli [1.4K]

Probability that the child would be homozygous for the g542x allele 0.00

<h3>why the probability is nil?
</h3>
  • The kid cannot be homozygous for the G542X gene since only the mother has it; the father, on the other hand, has a mutant dF508 allele and so cannot pass on a copy of mutant G542X = never homozygous recessive child.
  • A kid must have the G542X allele from both parents in order to be homozygous for the G542X allele. Because only the mother possesses the G542X gene, the child's chances of being homozygous for the G542X allele are 0.00
<h3>When offspring show a blend of the parents traits one allele is dominant over the other?</h3>
  • At the point when one allele is predominant over another, posterity show a mix of guardians' qualities.
  • The heterozygous aggregate in complete predominance is tracked in the middle of between two homozygous aggregates. A heterozygous individual showcases qualities of the two guardians in the event of codominance.

It is impossible for sperm to be functional (able to fertilize the egg) until after ________. Group of answer choices
lesya692 [45]

Answer:

The answer is "they undergo capacitation"

Explanation:

Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes. For a sperm cell to fertilize an egg, it takes approximately 24 hours. The surface of the egg changes as the sperm penetrates the egg, therefore no sperm is allowed within. The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.
