Cellular respiration associates oxygen with glucose within the mitochondria to generate ATP; water and carbon dioxide are generated as well. Photosynthesis utilizes energy from sunlight to produce glucose and distinct oxygen from carbon dioxide and water.
The cellular respiration uses the outcomes of photosynthesis and photosynthesis utilizes the outcomes of cellular respiration at its initial stage.
Both the process of cellular respiration and photosynthesis exhibit an equal enthalpy. Thus, the correct answer is option A.
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:
25%
Explanation:
The possible genotypes and phenotypes are:
- EE or Ee: thick eyebrows
- ee: thin eyebrows
- FF or Ff: free earlobes
- ff: attached earlobes
Tom and Jessica have thick eyebrows and free earlobes. Tom's mother has attached earlobes, so Tom must have inherited an <em>f</em> allele from her, and because he has free earlobes he must be heterozygous<em> Ff. </em>We assume Jessica is homozygous for free earlobes <em>FF</em>.
Tom's mother and Jessica's father have thin eyebrows, so they are both <em>ee</em> and therefore both Tom and Jessica must be heterozygous <em>Ee</em>.
From the above information, Tom has the genotype EeFf and Jessica is EeFF. If you do a Punnett Square of this cross, you'll get that the probability of having a child with free earlobes and thin eyebrows (eeF_) is 25%.
The best approach for Tyler is a controlled experiment if he wants to directly observe the outcome.
A controlled experiment is designed to minimize the effects of the variables other than the independent variable. A controlled experiment allows reliable results because he can do the experiment specific to the problem and variables involved.
