Answer:
Your answer is E). Fossils in different layers will obviously be much older/younger than others.
Answer:
The correct answer is - option C.
Explanation:
CFTR is a short form of cystic fibrosis transmembrane conductance regulator protein which is caused by a recessive mutation in this protein. This mutation results in the accumulation of mucus in secretory organs.
As the disease is a recessive disease, for the mutant phenotype to expressed both copies of the allele required to be recessive.
The mother is negative for the CFTR. Hence, she will not transfer the mutant allele to her child So, the child would have a wild-type phenotype even if the father having two copies of recessive allele.
Thus, the correct answer is - option C.
Answer:
(B) None of the answers are true...
Explanation:
(A) is wrong because the high levels of epinephrine promote activation of sympathetic nervous system that'll ultimately increase oxygen consumption.
(C) Elevated temperatures of body require immediate cooling that's why breathing rate gets high and ultimately the oxygen consumption.
(D) We all know that a vigorous dose of exercise always increases your bodies oxygen consumption.
<h3><u>Comparison between Galapagos penguin and cold adapted Emperor penguin of Antarctica:</u></h3>
<u>Galapagos penguin:</u>
- Galapagos penguins are the only species of penguins that live north of the Equator.
- The Galapagos penguins breed all-round the year.
- The Galapagos penguins are smaller compared to the cold-adapted emperor penguins of Antarctica.
- The breeding and nesting place of the Galapagos penguins lie on the shoreline.
<u>Emperor penguin:</u>
- The emperor penguins live and adapt to the cold Antarctic environment.
- The Emperor penguins breed only during the Antarctic winters.
- The nesting of emperor penguins is on ice cliffs and icebergs where the eggs are protected from the strong and cold Antarctic winds.
- However, both of these species of penguins are at risk of extinction due to the rise in temperature and shortage of foods.
