Answer:
Explanation:
Define key words/vocab words to solve.
Sometimes you have to define words in the definition too :-P
chemosynthesis - the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
maybe easier to understand below:
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.
Answer: c. If you cut an onion near a person, then his/her eyes will always begin to produce tears
Explanation:
Answer:
The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die
Explanation:
When two species are obligate mutualists, both species benefit one another in such a way that one cannot survive without the other. Hence, in order to find out if two species are indeed obligate mutualists, they should be transplanted together away from other species on one side, and also transplanted individually on another side.<em> </em>
<em>If they are obligate mutualists, the individual transplant would find it difficult to survive and should die in no time while the transplant done together should survive. All other factors being kept constant. </em>
The answer is; Choice D
ABC transporters are transmembrane proteins that enable active transportation of substances across the cell membrane. The protein is important in the movement of substances against their concentration gradient using ATP energy. ATP binding causes it to change conformation and bind the molecule being transported.
Answer:
A new rock is produced that is different from the original rock.
Explanation:
During chemical weathering, a new rock is produced that is different from the original rock.
- Chemical weathering is the chemical decomposition of rocks to form sediments and soils.
- A large chunk of rock combines with water, air and other chemical materials.
- This cause chemical action and a new substance is produced.
- This process is known as chemical weathering.
Physical weathering is the breaking down of rocks into smaller fragments.
