One trait that protects people from Malaria is Sickle Cell Anemia. The infected cells collapse when plasmodium tries to feed off them and prevents them from getting actin proteins. It guards the host from Malaria.
Another trait is people that are negative for the Duffy blood group have resistance to infections caused by p. vivax (plasmodium vivax).
Hope this helps, if there is anything else I can help you with, just drop a comment!
Answer:
<u>d. Skeletal muscle</u>
Explanation:
There are two components of efferent nervous system.
- <u>Somatic nervous system</u>
- <u>Autonomic nervous system</u>
<u>SOMATIC NERVOUS SYSTEM:</u>
Somatic nervous is one of the components of efferent/motor nervous system.
It controls <u>voluntary activities</u>. It involves the <u>control of skeletal muscles</u>.
It is composed of <u>the motor neuron and the innervating muscle</u>.
<u>AUTONOMIC NERVOUS SYSTEM:</u>
Autonomic nervous system is the other efferent/motor system of the body. It controls the <u>involuntary activities</u>. It involves the control of <u>cardiac muscle, glands and smooth muscles</u> of the body.
It is composed of<u> 2 neurons; preganglionic and postganglionic neurons.</u>
Autonomic nervous system is further divided into:
- Sympathetic nervous system (it is responsible for flight and fight responses)
- Parasympathetic Nervous system (it is responsible for rest and digestion)
- Enteric division ( controls Gastrointestinal system)
<u>QUESTION:</u>
<u>d. skeletal muscle</u>
This is the correct answer choice as skeletal muscles are not controlled by autonomic nervous system. They are controlled by somatic nervous system and are under voluntary control.
Yes it is because it is crossing over two different things to get something that you do not normally have and have something that was not made to be here
Answer:
The primary function of the plasma membrane is to protect the cell from its surroundings
The factor that is most likely to have the greatest effect on the number of molecules mitochondria can produce is the number of H+ ions moving down the channel.
Hydrogen ions move from the outer to the inner compartment of the mitochondria through the electron transport system. The main purpose of the electron transport chain is to build up a surplus of hydrogen ions or protons in the inner membrane space so that there will be a concentration gradient compared to the matrix of the mitochondria. The concentration gradient helps in the generation of energy in the form of ATP.
