The carbon cycle is the biogeochemical cycle by which carbon is exchanged between the biosphere, geosphere, hydrosphere, and atmosphere of the Earth. ... The ocean contains the largest active pool of carbon near the surface of the Earth, but the deep ocean part of this pool does not rapidly exchange with the atmosphere
Answer:
1/2 or 50%
Explanation:
Let us assume that the existence of heterozygous dark male means that the dark trait is dominant over the light trait. Hence, the light color trait is recessive.
Let us also assume that the dark color trait is represented by the allele A and the light color trait by allele a.
Heterozygous dark male = Aa
Light female = aa
Crossing the two:
Aa x aa
Aa Aa aa aa
Aa = dark color = 1/2 or 50%
aa = light color = 1/2 or 50%
<em>Hence, the probability of producing light-colored moths would be </em><em>1/2 </em><em>or </em><em>50%.</em>
Out of the following given choices;
(1) an increase in the number of clams
(2) a decrease in the number of water plants
(3) an increase in the number of crabs
(4) a decrease in the number of crayfish
The answer is D. Crayfish are are freshwater crustaceans resembling small
lobsters. Clams and crabs are found in marine waters. Most crayfish cannot
tolerate polluted water. Crayfish feed on animals and plants, either living or
decomposing, and detritus, therefore a decrease in small invertebrates in the river
would decrease their food source thence
consequently affect their numbers.
