<h2>Exponential Population Growth</h2>
Explanation:
The model of exponential population growth predicts that the per capita population growth rate, r :
d. does not change as the population gets larger.
A population shows exponential growth if there is no limitation on growth. All members have abundant resource availability and the population displays its intrinsic rate of increase.This is also known as geometric growth .In geometric growth, rate of increase is expressed as a constant fraction or an exponent by which a particular population is multiplied.
Answer:
<h2>
AAUAA deletion- (B
)
</h2><h2>
</h2><h2>
Poly(A) tail deletion- (C)
</h2><h2>
</h2><h2>
5' cap deletion- (A)
</h2>
Explanation:
(A) introns are not removed from the pre-mRNA due to 5' deletion;
(B) the pre-mRNA is not cleaved at the cleavage site due to AAUAA deletion
(C) the mRNA is not transported to the cytoplasm due to poly A tail deletion;
AAUAA deletion: if we delete the AAUAA sequence then there is the change of sequence of pre- mRNA that the pre-mRNA is not cleaved at the cleavage site
.
Poly(A) tail deletion: Poly(A) tail is the long tail of Adenine in the 3' end of mRNA, after the deletion of Poly(A) tail, it affects the transport of mRNA from the nucleus to the cytoplasm and the mRNA is not transported to the cytoplasm if tail is deleted.
5' cap deletion; the effect of 5' cap deletion is that introns are not removed from the pre-mRNA. The process of intron removing and exon joining is called RNA splicing.
Answer:
41 cycles
If cell division went 2 cell division cycle beyond the precursor; we have 43 cycles
The volume would be = 17.59 Litres
Explanation:
From the given information:
The number of cells in the liver that developed from an embryonic precursor is roughly 
The number of cell cycles needed to produce 
cells is:
= 
= 40.86
41
Thus, nearly 41 cycles of cell division are required to form the mature liver.
Now;
Suppose 2 extra cell division cycles took place;
The total number of cells would be 2⁴³ = 1.759 × 10¹³; &
The volume would be = 1.759 × 10¹³ × 10⁻¹²
The volume would be = 17.59 Litres
Answer:
Estrogen.
Explanation:
Plasma membrane is made of lipids and proteins. The lipids are arranged in bilayers and proteins are embedded or may span the lipid bilayer. The carbohydrates are attached on the surface of the membrane.
The molecules that are lipophillic in nature can easily diffuse through the plasma membrane. Among the molecules listed in the question, estrogen is highly lipophillic in nature and can easily cross the lipid bilayer of the plasma membrane.
Thus, the correct answer is option (d).
