Step 11 of skeletal muscle contraction:__________.
malfutka [58]

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.

A mating between a male donkey (2n = 62) and a female horse (2n = 64) produces sterile mules. why are mules sterile?
kirza4 [7]

The horse and donkey, though closely related by sharing a common ancestor, are different species. They have different number of chromosomes hence pairing of homologous chromosomes during fusion of gametes becomes complicated. The mule will have an extra chromosome from the horse hence will have abnormalities such as sterility. A Mule is unable to reproduce due to this same phenomenon. Homologous chromosomes are not well paired for meiosis I.

What is the difference between osmosis and diffusion? A) osmosis only occurs in marine (salt water) organisms B) they are the sa
sasho [114]

Answer: The correct answer is: C The are the same except osmosis specifically and only involves water.

Explanation:

Osmosis is the process in which a solvent moves across a semipermeable membrane in order to dilute a concentrated solution and it ends up equalizing the concentration of the solution at both sides of the cell membrane.

On the other hand, diffusion occurs when particles move from an area of higher concentration to an area of lower concentration and it ends up equalizing the concentration.

So the main difference is the presence/ Lack of water in the processes.

In conclusion the correct answer is : C.
