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:
50% of mice would be grey (GG [phenotype is grey and genotype is grey])
50% of mice would be grey and brown (GB [phenotype is grey and brown])
GG is complete dominance
GB is codominant
Answer: D
Explanation:
A positive feedback loop occurs in nature when the product of a reaction leads to an increase in that reaction.
In choice D melting of sea ice opens more ocean to sunlight which causes more ice to melt which demonstrated a positive feedback loop.
I would say I don't really don't know
The correct answer is - oxygen.
The phytoplankton and the microscopic marine plants are using the process of photosynthesis in order to produce energy for them. In order for this process to take place, two things are needed, sunlight and carbon dioxide. The consumed carbon dioxide is not totally used, but there's some waste from it. The waste is actually the oxygen. The oxygen is released and it gets back into the atmosphere. This gas is crucial for the survival of the living organisms on the planet, especially the animals, so it is extremely import that the environment of the phytoplankton and the microscopic marine plants is not destroyed, as they are the ones that release the biggest amount of oxygen into the atmosphere.
