Enzymes are proteins that control the speed of chemical reactions in your body. Without enzymes, these reactions would take place too slowly to keep you alive. Some enzymes, like the ones in your gut, break down large molecules into smaller ones.

Which of the following best explains what would happen if there were no autotrophs in an ecosystem? (1 point) They are the first

kogti [31]

Answer:

They are the first trophic level in an ecosystem and without them the rest of the organisms in the ecosystem would have no source of energy

Explanation:

The autotrophs are the producers in the ecosystem. They manage to produce food for themselves, and they represent the first trophic level, thus they are the basis of any ecosystem. These organisms are the once that produce the energy, and the organisms in the trophic levels above them use their energy to survive. If the autotrophs are removed from and ecosystem, the ecosystem will collapse, as there will be no source of energy for the organisms in the trophic levels above, thus all of them will die out quickly.

If a dna molecule is made up of 30% thymine what percent of it would be guanine

Evgen [1.6K]

20% would be guanine.

All 4 bases must equal 100.

30 thymine+30 adenine=60

100-60=40 of guanine and cytosine

40÷2=20 is just guanine

Answer:

muscles

ribs

lungs

bronchioles

alveoli

diffuses

leaves

exchange

Explanation:

Your diaphragm, and muscles between your ribs, make air move in and out of your lungs. It travels through the trachea, bronchi, and bronchioles to alveoli. In the alveoli, oxygen diffuses into the blood and carbon dioxide leaves. This is gas exchange.

Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.
