Answer:

C. Genes in DNA code for the production of proteins, which cause traits to be expressed.

Explanation:

A. Enzymes break down DNA, releasing amino acids that join to form proteins and express various traits. - this is false. DNA is not made up of amino acids, it is made up of nucleotides.

B. DNA is mutated by a chemical passed from parents to offspring to form proteins that express traits. - this is false. DNA itself is passed from parents to offspring. The DNA is transcribed into mRNA which is translated into proteins that express traits.

C. Genes in DNA code for the production of proteins, which cause traits to be expressed. - this is true. Genes are sections of DNA that encode for specific proteins. The structure and activity of these proteins determines all the functions in the cell and the body, and therefore specify all our traits.

D. Proteins bind to DNA, which activates them and forces them to express certain traits. - this is false. While proteins bind to DNA, this is not what causes them to become active and carry out their function to specify traits.

<u>Answer</u>: C) They can find the neighborhoods that are in the most danger, where to set up shelters, and which routes will help people reach safety.  

<u />

<u>Explanation</u>: GIS is an extremely useful tool in analyzing geographic information. By overlaying  topographic data as well as infrastructure, populations, bio-physical datasets (e.g. flood, landslide, storm surge, earthquake data), vulnerable areas as well are relatively safe areas can be detected. Thus, routes to safety as well as shelter construction can be planned.

The strength of an earthquake as well floodwater depth cannot be determined in advance with GIS. The bio.physical datasets that are used come from events that have already occurred and not future events. With GIS the damage caused by a future even can be <em>estimated</em>, but the strength of the natural disaster itself cannot.

_____ can be prescribed to therapeutically lower cholesterol levels.
maxonik [38]

Answer:

Niacin  can be prescribed to therapeutically lower cholesterol levels.

Explanation:

Niacin, known as vitamin B3, is used to reduce the risk of heart attack or stroke in people with high cholesterol. Niacin has gained popularity in the last 50 years and is mainly used to raise the level of HDL (high density lipoprotein) cholesterol, also known as good cholesterol and lowering bad cholesterol levels.

However, niacin can cause health damage, so it should always be used with medical supervision.

This is the force of attraction between an object and the earth due to gravity.
weeeeeb [17]

Answer:

Gravitational force

Explanation:

Gravitational force is the force that attracts an object down to the earth. It’s also the reason why we don’t float on this planet. This force is also why anything that isn’t thrown up must come down.

In space and other planets with little or no gravitational force ,organisms float over there which makes its inhabitation by organisms very difficult.
