Answer:
In humans, genetic variations are caused because humans reproduce by a sexual life cycle which is termed as meiosis. In such a life cycle, the offspring receives half the chromosomes from the mother and half from the father. Crossing over and random assortment of chromosomes are two phenomenons which occur during meiosis. Due to these two phenomenons, genetic variations are caused.
During crossing over, the exchange of DNA segments between the homologous chromosomes takes place which brings about the genetic variations.
Answer:
The suitable option will be - B
B) Phosphate and ADP form to make ATP which binds to the myosin head and causes cross-bridge to detach.
Explanation:
Until step 11, skeletal muscle has already done cross-bridge and power stroke. ADP is released just after the power stroke. After that phosphate and ADP form a new ATP which gets bound to the myosin head.
Then at step 11, cross-bridge is released as a new ATP is bound to myosin head.
So, we can say that option B is correct.
I believe that all members of one species form a population.
Passive transport DOES NOT need energy(ATP), while active transport does.
