<span>Almost all female progeny show the cleft chin trait so the percent would be 100%. This trait is normal called as dimples on the cheek. When you have cleft chin, it is quite possible that they have two dominant alleles or sometimes one dominant and one recessive allele.</span>

Classify the mutations as somatic or inherited
Sergio [31]

Answer:

Somatic mutations : option (A) and option (D).

Inherited mutations : option (B) and option (C).

Explanation:

Mutations are permanent changes in the genetic material due to alterations in DNA sequence. Mutations may be somatic or inherited (or germline).

Somatic mutations are those mutations that arise in somatic or normal body cells and cannot transfer from parents to their offspring. As skins cells and lung cells are somatic cells, option (A) and (D) represent somatic mutations.

Inherited mutations are those mutations that arise in sex cells (gamete forming cell) and transfer from parents to their offspring due to transfer as these cells form mutated gametes. As egg cells and sperms cells are sex cells, option (B) and (C) represent inherited mutations.

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.

Which is considered a modern space exploration project rather than a historical or future project?
Llana [10]

A.) Launch a satellite

Landing on the moon takes years to figure out. (How, when, what is the purpose,  etc.)  Capturing an asteroid is beyond difficult and would also take years to figure out how to do so.

Launching a space probe has yet to be done BUT we have had a satellite launched (hence how we get satellite images.)
