The alula is a small structure that is found on birds. It is located at the joint between the hand wing and the arm wings of birds and it is the freely moving, first digit of a bird's wing. It is normally used by birds in slow flight. In humans, the structure that is comparable to the alula is the thumb.
Answer:
The anerobic part takes place in the fluid part of the cytoplasm while the aerobic part takes place in the mitochondria

Answer:
The energy trapped in fossil fuels came from the energy plants converted during photosynthesis. This trapped energy is. chemical ... are using energy for
Explanation:
Answer:
The correct answer is option A, that is, cotransport proteins.
Explanation:
The variable that possesses the tendency to mediate energy based on chemical potential is termed as an electrochemical gradient. The electrochemical gradient is differentiated into two parts, that is, electrical gradient and chemical gradient. Both these forms of gradient take place over the surface of a membrane.
The movement of the majority of the ions takes place by the phenomenon of electrochemical gradients, of which some are found on the surface of the membrane and function as electrogenic pumps. While the gradients of some of the ions are mostly accounted for by the co-transport proteins, as these proteins take part in the movement of ions or molecules through a plasma membrane that involves concentration gradient based on the kind of molecules and movement.
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.
