I can exercise if the last time I ate food was 3 days ago. I can’t exercise if the last time I took a breath was 3 days ago. You need it or else you will pass out. I cannot even exercise vigorously if I stop breathing for a minute. My body will need oxygen and I will faint. You need to keep breathing at all times.

How does gravity affect surface processes
katovenus [111]

Answer:

Gravity can cause erosion and deposition. Gravity makes water and ice move. It also causes rock, soil, snow, or other material to move downhill in a process called mass movement. Particles in a steep sand pile move downhill.

Which of the following is a source of energy made from plant and animal remains?
bixtya [17]
Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.

In common dialogue, the term fossil fuel also includes hydrocarbon-containing natural resources that are not derived from animal or plant sources.

These are sometimes known instead as mineral fuels.

The utilization of fossil fuels has enabled large-scale industrial development and largely supplanted water-driven mills, as well as the combustion of wood or peat for heat.

Fossil fuel is a general term for buried combustible geologic deposits of organic materials, formed from decayed plants and animals that have been converted to crude oil, coal, natural gas, or heavy oils by exposure to heat and pressure in the earth's crust over hundreds of millions of years.

The burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases that allows radiative forcing and contributes to global warming.

A small portion of hydrocarbon-based fuels are biofuels derived from atmospheric carbon dioxide, and thus do not increase the net amount of carbon dioxide in the atmosphere.

To study the fate of carbon during glycolysis under aerobic conditions, cultured cells are fed with 14C-glucose labeled in vario
kondor19780726 [428]

Answer:

D. The methyl group of acetyl CoA becomes radio-labeled

Explanation:

During the steps in glycolysis, the carbon at position 1, becomes C-1 in dihydroxyacetone phosphate during the cleavage of fructose-1,6-bisphosphate to dihydroxyacetone phosphate and glyceraldehyde-3-phosphate. Subsequently on isomerization of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate, C-1 of dihydroxyacetone phosphate becomes C-3 of glyceraldehyde-3-phosphate.

Furthermore, in pyruvate, the end product of glycolysis, C-3 is converted to a methyl group which then becomes the methyl group in the acetyl-CoA molecule produced from the oxidative decarboxylation of pyruvate.

Since the radioactive 14-C of radio-labeled glucose occupies position 1, it will become the methyl group of acetyl-CoA.

How did you test your hypothesis? which variables did you control in your experiment and which variable did you change in order
elixir [45]

Hypothesis is a proposed explanation which is made on the basis of given experimental data taken as starting point for further investigation. All hypothesis test are conducted in a same manner fiollowing the four main steps:

1. State the hypothesis

2. Formulate an analysis plan

3. Analyzing the data obtained

4. Final step is to analyze the results

There are three types of variables taken in an experiment:

1. Independent variable: light, temperature, humidity

2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives

3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil
