C, it guarantees the survival of a species, for example there are a species of moth called the pepper moth, some of them are light and some of them are dark, where the pepper moths live has dark trees, the pepper moths that are lighter in color are likely to be eaten by birds because they are easier to see making the amount of light pepper moths scarce while the dark pepper moths live to breed and have offspring.
Question:
Which of the following actions could prevent mass-movement disasters?(a)constructing building and roads in stream drainage paths
(b)removing trees from steep slopes
(c)educating people about the advantages of building on steep slopes
(d)digging a series of trenches to divert water around a slope
<u>Answer</u>:
"Digging a series of trenches to divert water around a slope" could prevent mass-movement disasters
<u>Explanation</u>:
The trenches are made of 12 to 15 inches in width and at least 6-8 inches depth, can help in normal drainage problem. But in long, steep slopes and areas receiving heavy rainfall, digging of trenches is more advisable. It prevents the tripping over and falling down of people, it protects the runoff of edges and also collapsing. These trenches should be filled with coarse gravel or may be small stones. In the final labelling one or two inch of fine gravel or coarse sand. It will make the surface level which will allow the water to seep down.
It is referred to as a biochemical pathway because it converts the energy from the sun to chemical reactions that the plants can use in its cells

Answer:
A plant and animal cell both have a plasma membrane, ONLY a plant cell has a cell wall. Both of them have cytoplasm, a nucleus to guide them on what to do and ribosomes to produce protein. Only a plant contains a large vacuoles to store water and have chloroplast to do photosynthesis.
