Answer:
1. C
2. B
Explanation:
1. When a plant cell looses some water due to dehydration or being placed in a hypertonic solution, the term used to describe the cell's intial, not severe shrinkage is 'flaccid'.
Here, it's clear that the cell shrank so much that the cell membrane pulled away from the cell wall. The correct term for this severe shrinkage is 'plasmolysed'.
We don't use 'wilted' as a term to describe a cell. We use it to describe the plant as a whole.
2. This is the function of each. Water and ions in xylem and sugars like sucrose in phloem.
There are a lot of human activities that gives negative effects on the earth's ecosystem but I will mention only four: Burning of things such as garbages or plants and trees, dumping of garbages anywhere, chemical substance that are being made and produced, cutting down of trees for replacement of buildings and homes. The human activities increase the occurrence of species extinction by doing this, it eliminates and destroy the homes of the species that are supposed to be living on their natural habitat. But instead of them, living peacefully, by doing these activities, their home will be destroyed that can kill them-- which can lead to extinction.

Answer:
The process of the formation of Urine starts when the blood enters the kidney and is filtered by the nephrons to separate the water from the larger elements that compound it like blood cells and proteins. Then, they go to the blood, and the elements that passed the filtration membrane go to the renal tubule to be moved to the bladder or be reabsorbed in case they are necessary for the body.
Explanation:
The Urine creation process starts with the blood entering the nephron in the kidneys. Then it is filtrated blocking blood cells and large proteins, making only water and smaller elements pass the filtration membrane. Then, cells and proteins, as well as the elements that couldn't pass the filtration membrane, go back to the bloodstream. While the elements that passed the filtration membrane go to the nephron to enter the renal tubule. In this tube some of the components that can still be used by the body are reabsorbed, the rest continues its journey to the bladder.
