Answer:Conservation biologists, philosophers, environmental ethicists, and others offer several key reasons to conserve biodiversity. One argument is that organisms have direct economic value for humans. We use plants and animals for medicines, food, clothes, building materials, recreation, and other luxuries and necessities. But what if an organism that is of no use to us for food or hides is screened for useful medicinal compounds and found to have none? Do we sanction its extermination? Why must a plant or animal be of direct economic benefit to humans to have worth? Economic value alone is not the only reason to preserve biodiversity.
Another reason often given…to conserve biodiversity is that organisms, as components of ecosystems, provide services, and their interactions with other organisms contribute to the overall healthy functioning of ecosystems… On a practical level, biologists want to know just how much the loss of a few species will reduce the quality of services within a specific ecosystem. Two schools of thought prevail.

Answer:
Water will move into the cells.
Explanation:
Answer:
The DNA is a double stranded nucleotide. The DNA is consisted of deoxyribose sugar, phosphate group, and nitrogenous bases such as adenine, thymine, guanine, and cytosine.
The adenine always base pairs with thymine, so whatever the percentage of an adenine in a DNA strand is, always the same with thymine. Same thing with Guanine as it always base pairs with Cytosine.
A = T
G = C
Explanation:
Let's take the cow as an example.
If its adenine content is 28%, it has also 28% thymine content. 28 + 28 = 56% So, the remaining percentage is G and C, which is 44%. The 44% will be consisted of 22% guanine and 22% cytosine, making it 100%.
