Answer:
They use it in photosynthesis
Explanation:
When animals practice cellular respiration, the biproducts, such as CO2, are released into the environment. When a plant practices CR, the biproducts are immediately used as key reactants in photosynthesis.
Answer:
The statement which is correct is
<em>The evolutionary fitness associated with the heritable trait of DDT resistance changed once DDT use became widespread.</em>
Explanation:
In the 1930's, the usage if insecticides was minimal. Hence, the genes for DDT resistance were absent or silent in the fruit flies at that time.
In the 1960's, the DDT resistant forms of fruit fly began occurring at this rate because they were better adapted to survive. According to Darwin, the species which are better able to adapt to the environment survive and are able to reproduce. Hence, with the passage of time the resistant forms of fruit fly will keep reproducing and increase in number.

Answer:</h2>
Following are the examples of the given associations:
- Mutualism- Oxpecker and rhinoceros.
- Commensalism- Birds and tree.
- Parasitism- Sashimi and round worm.
<h2>
Explanation:</h2>
- <u>Mutualism</u>- It is a the interaction of two organisms of two different species in which each of them gets benefited from each other. For example- Oxpecker eats the ticks, pests and other parasites present on the body of Rhinoceros and hence both of them get benefited as the oxpecker gets food and in return rhinoceros gets pest control.
- <u>Commensalism</u>- it is a association in which two organisms get interacted in which one get benefited and the other is neither benefited nor harmed. For example birds living on trees generally do not harm tree in any case but in return gets food and shelter from the tree.
- <u>Parasitism</u> in aquatic environment- it is defined as the interaction of two organisms in which a organism lives in or on other organism of another species (its host) and benefits by deriving nutrients from the host at the host's expense. For example round worm or tapeworm obtain food and even complete their life cycle inside fishes like Sashimi and harms them.
Result: The above are the examples of the given associations.
Answer:
The correct answer would be -
1. the ocean have
2. water
3. acidic.
Explanation:
Carbon dioxide fro the atmosphere dissolves in the seawater naturally. This process can be understood by the following process:
Water and carbon dioxide reacts to form carbonic acid that can dissociate into either carbonate ion or bicarbonate ion:
1. CO2 + H2O ====> H2CO3⁻ (carbonic acid)
2. H2CO3⁻ ======> H⁺ + HCO3⁻ (bicarbonate ion)
3. H2CO3⁻ ======> 2H⁺ + CO3⁻ (carbonate ion)
Due to the presence of proton ions in seawater, seawater becomes more acidic. As hydrogen ions bind to the carbonate ions to make bicarbonate ions, the carbonate ion reduced which is required to form the
