B. Cytoplasm- is made up of a jelly-like substance composed of mainly water and found between the cell membrane and nucleus. The cytoplasm makes up most of the body cells which hold organelles as well.
Answer:
i hope it help
Explanation:
A person's genotype is not determined by their phenotype. The genotype is the genetic makeup of an individual and is the basic instructions for how the cell should make proteins that make up our traits. The phenotype is the physical appearance or characteristics of the person.
<span>An improved functional health can have a positive
influence on physical inactivity for this is a modifiable risk factor. The prevalence of improve functional health is
higher than physical inactivity compare to other risk factors because this will
encourage an individual to have a physical activity such as biking, swimming or
any routine physical fitness. </span>
Answer: FALSE
Explanation:
The nervous system is the system that detects and responds to changes inside and outside the body. This system consists of the brain, the spinal cord and peripheral nerves. The structure and organisation of the tissues that form these components enables rapid communication between different parts of the body.
Parts of the nervous system includes:
--> Central Nervous System ( consists of the brain and spinal cord)
--> Peripheral Nervous System ( consists of nerves outside the brain and spinal cord).The two functional parts of the peripheral nervous system are made up of the sensory (afferent) and motor (efferent). The motor division is involved in activities that are voluntary (somatic nervous system) and involuntary (autonomic nervous system).
The somatic motor division consists of somatic motor neurons that innervates ONLY the SKELETAL MUSCLE for its voluntary actions while the autonomic motor neurons innervates the cardiac and smooth muscles. Therefore the statement is FALSE
Answer:
Why are molecules such as valinomycin effective at transporting ions across the membrane?
Valinomycin is effective as transporting ions across the membrane because it is no charged, so it can carry ions.
Why would a drop in temperature to or below the transition temperature limit valinomycin mediated K+ transport across the plasma membrane?
Valinomycin is limited by temperature because its activity is highly sensitive and it depends on a stable and an average temperature.
Explanation:
Valinomycin is effective at transporting ion across the membrane because is an antibiotic that alternates hydroxy and amino acid, ans it helps membranes to be permeable. Valinomycin is a cyclic molecule that helps in ions transportation through membranes. Also, antibiotics have a temperature range of activity, that's why it is sensitive to changes.
