Diffusion, Osmosis and Enzymes
Nana76 [90]

The given statements can be matched as following:

a)The diffusion of water from a high concentration to a low concentration  - Osmosis

b)Lowers the amount of energy needed to perform chemical reactions - Enzymes

c)When you breath O2 passes into your blood stream while CO2 passes out of your blood stream -Simple Diffusion

d)Involved with, but does not become a part of chemical reactions -Enzymes

e)Small molecules with no charge can move through semi-permeable membranes by this process- Simple Diffusion

Explanation:

a) Osmosis is generally defined as the process by which water is transported from a region of Higher concentration to the region of Lower concentration.

b) Enzymes are well known to reduce the amount of energy required or needed for a chemical reaction to take place.

c)The process by which oxygen passes through our blood stream and carbondioxide passes through the other is known as simple diffusion process.

d) Enzymes are ones that actively gets involved in the chemical reaction but they will never become a part of that chemical reaction.

e) Diffusion is the process by which very small molecules that carries no charge moves through semi permeable membrane.

Suppose we discovered a form of life like our own which utilized 20 amino acids, but had 6 nitrogeneous bases instead of the 4 o
mezya [45]
The minimum legth of a codon could be two. If it was only one of the 6 nitrogeneous bases in a codon, we'd only have 6 possible amino acids. If we have, though, a combination of two amino acids out of the 6 nitrogeneous bases, we would have then 36 possible combinations (6 possibilities for the first position × 6 possibilities for the second position) that would allow the existence of the 20 different amino acids.
In the human case, for example, with only 4 nitrogeneous bases, a combination of two amino acids would be insufficient (4×4=16) for the 20 amino acids.

Which statement is true about natural selection?
Alik [6]

Answer:

I would say B

Explanation:

Because atural selection is the mechanism for how evolution occurs over time. Basically, natural selection says that individuals within a population of a species that have favorable adaptations for their environment will live long enough to reproduce and pass down those desirable traits to their offspring.

How might evidence from an experiment such as this help shape Darwin’s ideas about evolution?
Aliun [14]
It is supported by evidence from a wide variety of scientific disciplines, including genetics, which shows that different species have similarities in their DNA. There is also evidence supporting the Theory of Evolution in paleontology and geology.

anzhelika [568]

The answer is C. Hyperthermia. Pneumonia, frostbite, and hypothermia are all caused by the body getting abnormally cold, while hyperthermia is the condition of having a body temperature greatly above the normal temperature. Hope this helps!
