D) neither photosynthesis nor respiration.
The answer is muscle cells. This is because they are responsible
for either voluntary movement (skeletal muscle) or involuntary movement (smooth muscle). This movement requires energy to
power the movement of the actin and myosin action
that is the core of every muscle. Each myosin has an ATP-binding site.
Answer choices:
- A frame shift mutation in the X chromosome of a cheek cell
- A chromosomal mutation in the Y chromosome of a kidney cell
- A point mutation in the first chromosome of a sperm cell
- A substitution mutation in the third chromosome of a uterus cell
Answers:
A point mutation in the first chromosome of a sperm cell
Explanation:
Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.
Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.
D. it serves as a link between membrane proteins on adjacent membranes.
Chitin is not a lipid, it is a carbohydrate.
Everything else is a lipid.
