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.

Why do plants produce more carbon dioxide than oxygen during the night?
Eduardwww [97]

Answer:

During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.

what is true of intercellular signals that do not go through direct connections between cells such as a gap junctions
Nutka1998 [239]

The intercellular signals refer to the signals that conduct the signals from one cell to another, and these signals conduct messages within the cell. The intercellular signals may not be mediated via the gap junctions.  

The signaling molecules often exhibit a receptor on the cells, where the binding of the molecules takes place and leads to stimulation of the cell. The signaling molecules can also get inside the cells with the help of facilitated diffusion and active transport. So, this kind of conduction cannot mediate via gap junctions.  

Thus, the intracellular signals that do not pass through direct associations between cells like gap junctions, either enter the cell through the membrane or combine with the receptor molecule present on the surface of the cell.
