If you wanted to eliminate wind what would be the best way to do it
pychu [463]

Answer:

The best way to eliminate the wind is to build barriers.

Explanation:

As you may already know, the wind is a large-scale flow of gases. This flow is palpable and can be prevented from entering certain places by building physical barriers that block the flow. In this case, the construction of barriers prevents the wind from advancing and reaches a certain region, because it causes the wind to crash against this barrier and be pushed back, prevented from advancing.

Could you pleaseeee answer question 1 and 2 ASAPPP
I am Lyosha [343]

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.
