Answer:
G. Decomposing bacteria break down dead organisms and return nutrients to the soil.
Explanation:
Bacteria break down dead matter in the environment, for example, dead leaves, and release carbon dioxide and nutrients in the process. Without the release of carbon dioxide, plants are unable to grow.
Hope this helps you!
Answer:
2/4 = 50% of the offsring will be heterozygous
Answer:
9. 50%
10. There is a 2 in 4 probability their offspring will be Heterozygous for ear lobes
Explanation:
So if pendulous ear lobes are (E) and adherrent ear lobes are (e)
Its important to regonize that a man who has pendulous ear lobes whose mother had adherrent ear lobes should be written as (Ee) seeing as how the pendulous ear lobes are dominant over adherrent ear lobes
also, recognize that while using a punnet square you have a set of two alleles
Note: The husband is Heterozygous
The Husbands: (Ee) pendulous ear lobes
The Wifes: (ee) adherrent ear lobes
Heterozygous just means they can either pass on the pendulous ear lobes or adherrent ear lobes so their alleles look like (Ee)
you can begin the problem by using a punnet square:
e e
E Ee Ee
e ee ee
A.
3.1+2.7+4.6+8.7/ 4 because you have 4 numbers
Phosphorus biogeochemical cycle is least dependent on biotic processes
Explanation:
The slowest biogeochemical cycle, the phosphorus cycle doesn’t have a constant stability in the atmosphere unlike other biogeochemical cycles. Other cycles include- Carbon cycle, nitrogen cycle, water cycle etc.
Phosphorus has it’s cycle through the soil, water and sediment biotic factors. It persists in a small amount in the atmosphere and it has a liquid state in room temperature. It is a limited cycle for plants and animals.
