Answer:

The answer is all of the above are correct.

Explanation:

Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, bacteria oxidize hydrogen sulfide and add carbon dioxide and oxygen to produce sugar, sulfur, and water:  

CO2 + 4H2S + O2 ⇒ CH20 + 4S + 3H2O.

Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the seafloor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in seawater). Pure sulfur and sulfur compounds are produced as by-products.

How do plate tectonics explain the formation and metamorphic rocks?
Serga [27]

Metamorphic rocks are formed from other rock that has been subjected to very high temperature and pressure.

When one of the earth's plates comes in contact with another either by both traveling opposite directions, straight into each other, or from one slipping under the other (subduction zone), the pressure/friction of the plates against each other melts the rocks and after they cool they are metamorphic. Example is in Washington state when the Juan de fuca plate is going under the North American plate the pressure/friction of this melts the rocks which then form metmorphic rock.

If you walk through a busy crowd and feel a few different people bump and push past you as they walk by, which skin receptors wo
Likurg_2 [28]

Answer:

Mechanoreceptors would be activated

Explanation:

The skin is a complex organ that is found covering the entire surface of the human body. The mechanoreceptors are responsible for the sense of touch, that is, the capture of pressure on the skin. They are the Meissner corpuscles and the Vater-Pacini corpuscles, which are made up of nerve endings and connective tissue, in other words, they are receptors that are stimulated by muscle contraction and pressure on the joint elements. It allows to know the position of the body and the degree of contraction of the muscles.

A cotton farmer applies a new insecticide against the boll weevil to his crop for several years. at first, the treatment was suc
romanna [79]
Yes, it is possible that evolution occurs in this case.

At first, the new insecticide is effective against the boll weevil. Spraying the insecticide will kill the boll weevil in a way. The insecticide might attack boll weevil enzyme or any part of its organs.<span>
But some of them might have a mutation that renders the insecticide ineffective. The mutation probably happens to DNA that code the enzyme or protein that targeted by the insecticide, makes the insecticide completely ineffective.
The next spray will kill all old organism, leaving the new resistant organism in less competition area. This will allow the resistant organism to grow fast and eventually replace all the old organism in the area.</span>

What does it mean when scientists say that living organisms share a universal genetic code
DaniilM [7]
 <span>All living organisms have a shared ancestor deep in the past, so all living organisms are related to some degree. We might share 99.8% DNA with chimps, but we also share maybe (just a guess, I don't remember the exact number) 24% DNA with lettuce. If all living organisms are related, than their genetic code is universal - one and the same for all organisms.</span>
