6 0

Answer:

C. Diffusion and no energy needed.

Explanation:

A - Passive transport doesn't require energy.

B - Osmosis would be if the 25% H2O went into the 82%

D - Active transport doesn't apply because molecules aren't moving across into a higher concentration.

Diffusion is when parts of the 82% go into the 25%.

spayn [35]

Pollution can come from both natural sources and human activities depending on the type of pollutant.

<h3>What is pollution?</h3>

It is the release of substances into the environment to the extent that the well-being of plants, animals, and humans starts getting affected.

Substances that are released into the environment to the extent that they start affecting the organisms in the environment negatively are known as pollutants.

Pollutants can come from natural sources or as a result of human activities.

For example pollutants such as oxides of sulfur, methane, carbon dioxide, etc. can come from natural processes such as volcanic eruptions, activities of microbes, etc.

Pollutants such as oxides of carbon and sulfur can also be generated as a result of human activities such as the burning of coal, technological inventions, etc.

Suppose there is a protein "A" which binds to a DNA sequence and increases transcription of the gene CBC23. In the presence of m
fenix001 [56]

Answer:

A = Activator

B = Effector

Explanation:

An activator is a protein which typically binds to a short (50–1500 bp) region of DNA which might be located either upstream (mainly) or downstream of a gene so as to cause increased transcription. This particular region of DNA is known as enhancer and activator is also  known as transcription factor. Activator is a trans-acting factor which binds to the cis-acting factor which is enhancer so as to enhance transcriptional expression.

But another protein named as effector may restrict activator from binding to the enhancer leading to a decrease in transcriptional expression by binding to the activator allosterically. Allosteric binding of effector to the activator causes conformational change in activator so it can no longer bind the enhancer.
