Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD.

a. True
b. False

Answers

Answer 1

Answer:

As you age, your body may reabsorb calcium and phosphate from your bones instead of keeping these minerals in your bones. This makes your bones weaker. When this process reaches a certain stage, it is called osteoporosis. Many times, a person will fracture a bone before they even know they have bone loss.

Answers

Answer:

The reactions of glycolysis that are shared with those in gluconeogenesis (ie use the same enzymes) are those that Are regulated steps.

Explanation:

Glycolisis and gluconeogenesis are two mechanisms related to the carbohydrates metabolism.  Sometimes they are considered reverse processes. However, they are different because of the control points they have where reactions are irreversible.

Glycolisis and gluconeogenesis share 7 common reactions, that are reversible. Thses reactions are coordinated and regulated by F-2 and 6-BP as the answer to the hormonal action.

Glycolisis happens in the muscle, while Gluconeogenesis happens in the liver. Together they form the "Cori Cycle".

Answer:

Carbon dioxide

How do you blow up a balloon? You might know that carbon dioxide is what we exhale into a balloon, but where does it come from? Carbon dioxide is a waste product from a process called cellular respiration, which uses oxygen and sugar to make energy and carbon dioxide.

What is carbon dioxide?

Carbon dioxide (chemical formula CO2) is a chemical compound occurring as a colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. The current concentration is about 0.04% (417 ppm) by volume, having risen from pre-industrial levels of 280 ppm. In water it forms an acidic solution due to the formation of carbonic acid (H2CO3). Natural sources include volcanoes, forest fires, hot springs, geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, ice caps, glaciers and seawater. It is present in deposits of petroleum and natural gas. Carbon dioxide has a sharp and acidic odor and generates the taste of soda water in the mouth, but at normally encountered concentrations it is odorless.

As the source of available carbon in the carbon cycle, atmospheric carbon dioxide is the primary carbon source for life on Earth and its concentration in Earth's pre-industrial atmosphere since late in the Precambrian has been regulated by photosynthetic organisms and geological phenomena. Plants, algae and cyanobacteria use energy from sunlight to synthesize carbohydrates from carbon dioxide and water in a process called photosynthesis, which produces oxygen as a waste product

What type of conservation will result in the greatest reduction in the burning of fossil fuels?

Answers

Answer:

Conservation of air.

Explanation:

Conservation of air will result due to greatest decrease in the burning of fossil fuels because fossil fuels greatly damage the air. The burning of fossil fuels produces carbondioxide gas in large amount that can be released in the atmosphere. This increase in carbondioxide gas in the air causes pollution that leads to global warming as well as health problems in humans. So we can conclude that decrease the use of fossil fuel leads to conservation of air.
