if body fluids are separated from pure water by a permeable membrane,_____

Answer:

Explanation:

Sedimentary rocks are rocks that are formed near the Earth’s surface. It js formed through a sucessive geological processes this include erosion, weathering, dissolution, precipitation, and lithification.

Physical weathering: Sedimentary rocks are layered rocks with many fractures from contracting during cooling. These cracks are opened up as the rock is brought to the surface and it allows water to get in. On freezing the water expands causing the cracks to widen and grow.

chemical weathering. Rain water can be slightly acidic and at times acid rain. This Acid dissolves many minerals particularly in crustal rocks, acid attacks carbonate found in sedimentary rock and feldspar, a principal ingredient of granite dissolving them.

Biological weathering:

Living things also lead to the breakdown of rock into fragments. Roots and burrowing animals physically disrupt rocks leading to the formation of soil.

The results of all the weathering processes is q heap of loose rock fragments and dissolved ions such as salt, bicarbonate, potassium.

The clastics blown away are carried by glaciers from the source region to a catchment area this is called sedimentary basin

A coenzyme is a chemical that works in conjunction with an enzyme to activate it and aid in its function. An organic molecule that binds to the active sites of specific enzymes is known as a coenzyme and helps catalyse reactions.

To be more precise, coenzymes can serve as functional groups that are exchanged between enzymes or act as intermediate carriers of electrons during these reactions.Coenzymes, which are organic compounds, are necessary for the catalytic activity of many enzymes. They typically have vitamins or vitamin-like substances in them.

They can occasionally serve as catalysts in the absence of enzymes, however not as efficiently as when an enzyme is present.Coenzymes are mostly made from vitamins and other minor amounts of other organic vital elements. (While both types of inorganic compounds are mentioned here, some scientists restrict the word "cofactor" to them.)

Explanation:

Answer:

4. All organisms of a species will survive

Explanation:

4 is the complete opposite of natural selection.

Natural selection basically says that certain members of the species will die off and the more fit ones will survive and produce stronger, better-adapted offspring.

As concentration of substrate is increased in a reaction catalyzed by an enzyme, the reaction rate will stop increasing once saturation is reached because all enzymes are actively engaged in a reaction.

In the field of science, enzymes can be described as biological catalysts that speed up a reaction.

An enzyme is specific for its activity as a specific substrate fits into the active site of the enzyme. When the concentration of a substrate is increased, the rate of reaction will also increase until saturation is achieved. This will be the point where there will be no more free active sites of enzymes left for substrates. Each enzyme will already be having a substrate at this point.

In order to further increase the reaction rate, the quantity of the enzyme should also be increased so that there are more active sites present for substrates.

Although a part of your question is missing, you might be referring to this question:

As concentration of substrate is increased in a reaction catalyzed by an enzyme, the reaction rate will stop increasing once saturation is reached because

A. There are too many enzymes available and not enough substrate

B. once the enzyme reacts once, they cannot react again

C. all enzymes are already engaged in a reaction

D. increasing substrate inhibits enzyme activity

Answer:

Mimicry

Explanation:

Mimicry can described or explained as the process whereby one organism copy the action of others and do exactly the same as that copied organism.

This is usually done when the action copied from the organism is useful in escaping from predators or being seen by other organisms as a predator and allow it to have access to the available resources.

In this case, when other organism copy the bright coloration of that small poisonous organism to drive away other organism, it is called mimicry.

Salt is less than 1

Red blood cells have a salt content of 0.9%. When a microbiologist places red blood cells in pure water, osmosis occurs. This results into water molecules . Thus, the correct option is C.

Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential or lower solute concentration to a region of low water potential or higher solute concentration, in the direction which tends to equalize the solute concentrations on the two sides of the membrane.

It is of two types, on the basis of movement of solvent particles, when the solvent moves inside the cell it is called endosmosis which results into turgid cells and the movement of solvent molecules outside the cell which is called exosmosis that results into flaccid cells.

Therefore, the correct option is C.
