Abiotic factors are things that aren't living that effect an environment, like pH (how acidic the soil is), the temperature, amount of light, and so on. These can effect a population by making it more difficult to survive, perhaps creating more competition over available resources and so on. So for example, if the soil is really acidic in an area, a population of plants may not be able to grow well in that environment.
Incomplete question. The full question read;
If the US modifies techniques for timber management, it is expected that US forests will
a. not be able to meet long term timber needs
b. be able to meet long term timber needs
c. result in deforestation
d. provide increasingly cheaper timber
Answer:
<u>b. be able to meet long term timber needs</u>
Explanation:
<em>Remember</em>, the emphasis here is on the modification of the present techniques for timber management in order to boost productivity.
Hence, we can conclude that since there would be an improvement in production efficiency,<em> the US would be able to meet its long-term timber needs.</em>

Answer : Groundwater is generally much cleaner than surface water. So ✨Yes✨
Why : Groundwater is less susceptible to pollution than surface water because as water enters the ground, the soil and rocks naturally filter much of the water as it passes through the ground.
✨Hopes this Helps!✨
Answer:
They have more bonds (ionic, vdW, polar, peptide, hydrogen) and a thicker phospholipid bilayer than their similarly-structured heat-intolerant counterparts-DNA - two bonds between adenine and thymine, three bonds between cytosine and guanine, MORE C-G PAIRINGS2.
