As a solute concentration rises, its rate of transport through a membrane increases up to the point where all the carriers are saturated. This point of saturation is called what
Answer:
transport maximum
Explanation:
In the context of physiology, this point of saturation is called the transport maximum. Like mentioned, this is the point in which any further increase in the concentration of a substance no longer results in an increase in movement of that substance across a cell membrane, thus indicating that the carrier of that substance is completely saturated and can no longer complete its function.
Lions and cheetahs' prey on wildebeests that graze in the grasslands of the African savanna. What likely impact will having increased rainfall over several rainy seasons have on the populations of wildebeests, lions, and cheetahs?
A )All three populations would increase.
B )The wildebeest population would decrease, and the lion and cheetah populations would increase.
C) The wildebeest population would increase, and the lion and cheetah populations would decrease.
D)All three populations would decrease.
Answer: B
Explanation: Because since the wildebeest eat grass and there is a increase in rain fall there will be more wilebeest for the cheetahs to eat and then more of them for the lions to eat
In a small population of Brazilian natives, the frequency of gene p, responsible for this disease, is 0.3. What must be the frequency of people who are heterozygous for this disease?
Answer:
Explanation:
According to hardy weinberg
p+q=1
p2+2pq+q2=1
p stands for the dominant genotype
q stands for recessive genotype
pq stands for population that are not homogenous i.e not the same
Given that p=0.3
P2=0.09
q=1-0.3= 0.7
q2=0.49
2pq= 2×0.3×0.7
=0.42
Therefore, the frequency of heterozygous population is 0.42
p2+2pq+q2
0.09+0.42+0.49 = 1
How are muscle cells in bone cells similar
Explanation:
Bones shape our body and help is to stand up straight. Muscles are attached to bones, they help us walk and run and smile. All the bones in our body make up our skeleton - from the top of our skill to the tips of our phalanges at the end of our toes. Muscles stretch across our bones and are attached with tendons.

explain how the biosphere facilities movement of water from the geosphere to the atomosphere.
Answer:
Explain how the biosphere facilitates movement of water from the geosphere to the atmosphere. The biosphere includes all living components of the Earth. ... Water from the plants is incorporated into the atmosphere through a process called transpiration, where water from the plant evaporates and enters the atmosphere.
Answer:
The biosphere includes all living components of the Earth. Plants, a part of the biosphere, pull water from the ground, part of the geosphere, for their use in the process of creating food. Water from the plants is incorporated into the atmosphere through a process called transpiration, where water from the plant evaporates and enters the atmosphere

Why are ions important to metabolism?
A.) Some enzymes turn ions into substrates.
B.) Some enzymes require specific ions to work.
C.) Ions are not important to metabolism.
D.) Some enzymes break down into ions.
Answer:
Your answer is B
Explanation:
Ions play an important role in the metabolism of all organisms as reflected by the wide variety of chemical reactions in which they take part.
Ions are important to metabolism because some enzymes require specific ions to work. Thus, the correct option is B.
What is Metabolism?Metabolism may be defined as a set of methodologies that involves gradual and continuous chemical alterations that take place inside the cell or the body of an individual in order to stimulate the rate of survival.
Metabolism is also characterized as the sum of the chemical reactions that occurs within each cell of a living organism in order to furnish energy for vital processes.
Ions are an inorganic form of molecules that are loosely associated with the enzyme in order to ensure its effective function. Ions like [tex]Na^+, Mg^2^+, Ca^2^+[/tex], etc. are most prevalent.
Therefore, ions are important to metabolism because some enzymes require specific ions to work. Thus, the correct option is B.

Is the widely accepted scientific theory that characteristics of a population may change over time, and that current species may gradually give rise to new species.
Answer:
Evolution theory
Explanation:
The evolution theory was developed by Darwin and it is a generally accepted theory that deals with gradual changes in the characteristics of organisms due to their quests to adapt to continuous changes in the environment.
As the environment of organisms keeps changing, the population of the organism keeps adjusting. Individuals that are able to adjust to the changes survive and are able to reproduce while the weak ones gradually die off from the population.
Hence, the entire characteristics of the population is changed with time as a result. The continuous changes sometimes lead to some species within the population giving rise to a new species entirely.
