irakobra [83]

Lipids insulate against the cold. Fat is our natural coat produced by the over eating process. Not really sure, but it comes to mind that the layer under the skin can be the main reason for it as it prevents and keep our inner parts warm. Also the high blood flow that it demands can help by over circulating it.

Which of the following statements about energy is TRUE? Question 17 options: It can be used over and over again. It tends to be

Law Incorporation [45]

<h2>Energy </h2>

Explanation:

Energy flows in only one direction through an ecosystem

The Sun supports most of Earth's ecosystems
Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
The food energy created by producers is passed to consumers, scavengers, and decomposers
Energy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic level
Most of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproduction
So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
Animals at the third level have only 10% as much available to them as those at the second level

What does cellular respiration have to do with metabolic processes?

bixtya [17]

Answer:

Metabolism refers to all the chemical reactions in the body, including those that use oxygen and create carbon dioxide. Oxygen and carbon dioxide, therefore, are involved in both respiration and metabolism. Metabolic reactions are sometimes referred to as cellular respiration, which can cause confusion.

bonufazy [111]

Answer:

RNA

Explanation:

CRISPR system was discovered by a Japanese scientist. Naturally bacteria and many other prokaryotes have CRISPR system in their genome which they use as a self defense against a pathogen which is invading them. It consists of inter spaced, short palindromic nucleotide repeats which encode a guide RNA (gRNA). This guide RNA (gRNA) recognizes the target sequence on the pathogen. The gRNA is followed by Cas9 enzyme which along with the gRNA plays a very important role in breaking genome of the pathogen. Once the target gene is cut down the rest of the DNA can be rejoined by non homologous end joining.

But nowadays, scientists are using this system for genome editing and incorporating desired gene between the two ends which are cut down by CRISPR Cas9 system.
