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.
Answer:
DNA starts off on the nucleus where it then gets separated into DRNA so that it can travel to other parts of the cell. It is the. Carried by vehicle to the rough ER where ribosomes are added to it then it goes to the smooth ER where waste is expelled. Finally, it goes to the Golgi apparatus where it is either stored or carried to a part of the cell.
Explanation:
This is true. They are structured to keep well in cold environments so sticking them places such as the refrigerator keeps the well conserved for some time.
Answer:
The purpose of fungi and algae is to decompose dead plants and animals to break them down into smaller molecules that can be used by other members of the ecosystem
Explanation:
Answer:
This is true.
Explanation:
More commonly, an X chromosome will die and get replaced by a Y chromosome (all humans start off as females). When this occurs, the substitute Y chromosome causes changes in the zygote to occur; they begin developing male genitalia (i.e. penises, testicles, prostates, etc.).
