Which principle helps to explain the reason behind why alleles for a single trait separate from each other when gametes are made
Oksanka [162]
<span>Segregation

For a trait to show or express itself in an individual it must have two types of the same allele (for example P and p) showing on the chromosomes. The showing of both alleles on an offspring's chromosomes means that both parents have the same trait and that is why there is a chance for an allele to become dominant in other words to express itself in the offspring. However if only one allele is transferred in the genes of the offspring that means that the trait that the allele is responsible for, will remain unexpressed.</span>

What part of the rotifer is responsible for crushing food?
frozen [14]

Answer:

Rotifers are specialists at living in habitats where water dries up regularly.

The Monogononta, which have males, produce fertilised 'resting eggs' which can resist desiccation (drought) for long periods.[11]

The Bdelloids, who have no males, contract into an inert form and lose almost all body water, a process known as cryptobiosis. Bdelloids can also survive the dry state for long periods: the longest well-documented dormancy is nine years. After they have dried, they may be revived by adding water. In this, and several other ways, they are a unique group of animals.[12]

Explanation:

The front has a ring of cilia circling the mouth. This gave the rotifers their old name of "wheel animalules". There is a protective lorica round its body, and a foot. Inside the lorica are the usual organs in miniturised form: a brain, an eye-spot, jaws, stomach, kidneys, urinary bladder.

Rotifers have a number of unusual features. Biologists suppose that these peculiarities are adaptations to their small size and the transient (fast changing) nature of its habitats.

d1i1m1o1n [39]

Answer:

Needs optimum environmental conditions.

Explanation:

Seedling, a flower and a vegetable needs suitable conditions for growth and development. All of the three stages of plant life cycle requires optimum water, fertilizers and light intensity in order to grow and develop at full speed. Seeds need a specific temperature in order to germinate. Most seeds germinate when the soil temperature is between 68 and 86 Fahrenheit. In the same way the plant also needs specific temperature for bearing flowers. All the stages requires optimum water in the soil for absorption.
