The quadriceps muscles will contract.
Explanation:
Quardriceps are muscles of the thigh located in the front.
It is a group of four vastus muscles named as-the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris.
Muscles posses the ability of contraction so an action potential that will excite the muscle cells will obviously result in contraction of the muscles.
So we can conclude that on depolarizing the muscle cell of the quadriceps will result in contraction of quadriceps.
Answer: Cell membrane has many properties which is stated below.
Explanation:
The cell membrane allow one cell to communicate with other cell. It is the cell membrane which is directly in contact with the cell membrane of the another cell.
The cell membrane also serves as a channel for the transport of materials from the outside to inside and vice versa.
It also provides stability to the cell. It combines with the carbohydrates and provides immune response and cell recognition.
Answer:
ice age/ Quaternary glaciation
Explanation:
Ice ages have occurred in the earth history and do occur more or less regularly in a cycle. It is believed that ice ages are as a result of small changes in the earth's orbit and also dependent on the solar cycles. The temperatures on the earth reduce causing the ice sheets in the poles to extend to the subtropics.
Answer:
The correct answer will be option C- A structure upon which proteins are assembled.
Explanation:
A ribosome is a complex molecule machine formed of proteins and rRNA molecules which acts as a site for the synthesis of the proteins.
These ribosomes are present in the cell as a free entity suspended in the cytosol or attached to the endoplasmic reticulum.
Each ribosome is made up of a large and small component which translates the information coded in the mRNA in the form of codons to amino acids which join to form proteins.
Thus, option- C is the correct answer.
since he memorized 15, he has only 10 left. so it should be 10/25
