the hormones must attach to receptors before it is taken into the cell. So hormones that can perfectly fit into the receptors present in cell's membrane can enter the cell others cannot.
SO basically their ability to fit into the receptors

Explanation:
Chromosomal inversions, as its name suggests, are alterations that occur when a portion of the chromosome splits off but rejoins the chromosome in reverse. The genetic material remains the same, however, the disposition of information occurs in a exchanged manner.
We can classify chromosomal inversion into two types:
- Pericentric: Pericentric inversion occurs when the region undergoing inversion surrounds the centromere.
- Paracentric: Paracentric inversion occurs when the inverted region does not involve the centromere.
Answer:
<h2>3/16
</h2>
Explanation:
Given:
Parents are;
both parents are Agouti black and agouti black ( AaBb);
Black is dominant on brown (B over b);
Agouti is dominant on solid color ( A over a);
So, progeny are
(AABB, AaBb, AABb, AaBB, Aabb, aaBB, aaBb aabb so on )
Here 3 out of 16 progeny are agouti brown ( genotype AAbb, Aabb);
So,expected frequency of agouti brown offspring in the litter= 3/16.
