<span>A human body is composed of muscles. Without it, the human body cannot function and will die. </span>
There are three types of muscle tissues: Skeletal muscle, Cardiac muscle, and Smooth muscle.
The skeletal muscle aids in the movement of the human skeleton. The 600 skeletal muscles make up 40 % of our body weight and are reliant on the signals released by our nervous system to start moving.
<span>Cardiac muscles are those muscles which encloses our hearts. They are involuntary muscles which pumps blood throughout our bodies by creating steady and rythmic pulsing. They also make our heart contract by producing electrical impulses. </span>
<span>Smooth muscles are found in the walls of blood vessels, respiratory passageways, and hollow organs. Its contracting movement is wavelike and it helps in the transfer of food through our stomachs or urine through our bladder. </span>
<span>These muscles responds to nerve impulses and other stimuli.</span>
They have limited access to nutrients. <span />
Answer:
removal of introns, addition of 5' cap and 3' tail to mRNA.
Explanation:
The mRNA is processed before it leaves nucleus. The introns are removed and exons are remain in mRNA. This process is called splicing. The 5' end is attached with a cap and 3' is attached with a polyadenylated tail. Thus mRNA is processed with these process before it leaves the nucleus.
Answer: I would increase the temperature of the ocean and lower the percentage of pH so that users see how the ocean is affected by human activity, human activity causes the pollution of the air that causes CO2, which leads to all that CO2 is absorbed by the seas thus increasing the amount of acidity which brings as a consequence the increase in temperature and the dissolution of coral reefs.
Answer:
B
Explanation:
the quality of air will help identify any pollutants in the air.
