Answer:
After being hunted almost to extinction, the humpback whale population has rebounded dramatically. Rapidly melting Antarctica ice poses a threat to coastal cities, but there is at least one species that is benefiting: Humpback whales are flourishing these days, due to an abundance of krill.
Pre-hunting population size may have been as many as 200,000-300,000 whales. They were estimated to number around 2,300 in 1998 and to be increasing between 2.4-8.4% per year. The IWC is undertaking an assessment of Antarctic blue whales at present.
Answer:
Option A
Explanation:
Given -
Man has X-linked recessive trait . Thus its genotype can be represented as
YX'
Woman has normal vision with homozygous genotype i.e "XX"
A cross is carried out between the above two parents thereby producing following offspring -
Y X’
X XY XX’
X XY XX’
Out of four offspring two are boy "XY" which do not have Red-Green Color blindness
While the two daughters "XX' " have Red-Green Color blindness
Thus, all the daughters produced have Red-Green Color blindness. Thus the chance of having a daughter with color blindness is 100 percent
Option A
Acetyl CoA is a feed forward activator of the enzyme <u> pyruvate carboxylase</u> ensuring sufficient oxaloacetate for the citric acid cycle to continue.
<h3>Why does acetyl-CoA stimulate pyruvate carboxylase?</h3>
Acetyl-CoA selectively activates pyruvate carboxylase. When acetyl-CoA concentrations are high, organisms use pyruvate carboxylase to divert pyruvate from the TCA cycle because acetyl-CoA is a crucial metabolite in the TCA cycle that generates a lot of energy. The production of more oxaloacetate is triggered by an excess of mitochondrial acetyl-CoA.
Acetyl coenzyme A, often known as acetyl-CoA, is a crucial component in metabolism and is involved in numerous metabolic processes. Its major job is to transport the acetyl group's carbon atoms to the Krebs cycle, where they can be oxidized to produce energy. When there is an abundance of acetyl CoA available, the mitochondrial enzyme pyruvate carboxylase (PC) catalyzes the conversion of pyruvate to oxaloacetate.
