A condition in which the force of the blood against the artery walls is too high.
Usually hypertension is defined as blood pressure above 140/90, and is considered severe if the pressure is above 180/120.
Answer:
500
Explanation:
Mutation rate is largely known as changes that occur in the frequency of a particular gene over an extended period of time
So given that;
the mutation rate of a particular gene = 1 × 10⁻⁶
The expected mutations after 500 million sperm are examined will be:
= (1 × 10⁻⁶)×(500,000,000)
= 500
Thus, The expected mutations = 500
Answer:
C
Explanation:
It moves across the cell membrane via simple diffusion, a process that requires no energy input and is driven by the difference in concentration levels on each side of the cell membrane.
Answer:
b) Channel pumps
Explanation:
The channels are the transmembrane proteins that serve in the passive transport of substances down the concentration gradient. The channels can be gated or non-gated. The gated channels are opened and closed in response to certain stimuli such as electrical change.
For example, aquaporins are the gated water channels that transport the water across the plasma membrane. The process is driven by the osmotic gradient and does not use the energy of ATP.
Answer:
enzyme activity be affected by a variety of factors such as temperature,pH, concentration
