Which of the following chemicals opens us binding sites allowing muscle filaments to connect to each other? Select one:
HACTEHA [7]

Answer:

The correct answer will be option-D.

Explanation:

Calcium plays an important role in muscle contraction as they are released from the sarcoplasmic reticulum after they receive electric impulse.

Calcium triggers the muscle contraction cycle as these calcium ions bind to the troponin-tropomyosin complex. This binding exposes the myosin-binding site on the actin on which high energy myosin binds and cross-bridge is formed.

This cross-bridge formation causes the contraction of the sarcomere and therefore muscle contracts.

Thus, option-D is the correct answer.

I need to see said graph but to my understanding most under weight babies are born early so their body is not fully developed but as an slightly over sized baby myself the biggest problem was for my mom because she had to have a c section because I was too big to come out the normal way

by the way c section stands for Cesarean section

hope all this helps

Which of the following does not contribute to the formation of the mid atlantic ridge
dedylja [7]

Answer:

This submarine Mid-Atlantic Ridge owes its formation to the movement of the continental plates on either side of the ocean. As these plates slowly separate, they leave gaps in the earth's crust. This allows molten rock from beneath the earth's crust to reach the surface, forming a new part of the ocean floor
