Color-blindness is caused by an X-linked recessive allele. Which of the following is true?
A- mitochondrian
B- endoplasmic reticulum
C- lysosome
D- golgi apparatus
NAD +molecule
Explanation:
Krebs cycle and electron transport chain are important steps in cellular respiration.
In the Krebs cycle, there is a need of NAD+ molecule which is then in Krebs cycle reduced to form a NADH2 molecule.
NADH2 is also an energy currency. It , giving electron in electron transport chain and return to Krebs cycle as NAD+.
Now in the Krebs cycle, it is ready to take electrons again.
The statement is true as t<span>he two chambers at the bottom of your heart are called ventricles.
A ventricle is one of two vast chambers in the heart that gather and remove blood got from a chamber towards the fringe beds inside the body and lungs. The chamber (a contiguous/upper heart chamber that is littler than a ventricle) prepares.

Answer:
b. Hiccupping is a vestigial reflex that suggests a common ancestry between humans and amphibians.
Explanation:
Hiccupping refers to an involuntary contraction of the diaphragm that usually occurs several times per minute. Some research has suggested that hiccuping is an evolutionary remnant of amphibian respiration. This is because the mechanism is remarkably similar to the way tadpoles gulp air and water across their gills. This would mean that hiccups exist due to an antecedent to modern lung respiration.
