The statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.
<h3>What is eutrophication?</h3>
Eutrophication is the ecosystem's response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.
Eutrophication is one major effect of the anthropogenic activities that release inorganic nutrients such as phosphate, nitrate etc into aquatic ecosystems.
However, eutrophication has its negative impacts on biogeochemical cycle as it alters the cycling of these nutrients.
Therefore, the statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.

Answer:
50% chance of their son being colorblind
Explanation:
A Punett square for the man’s mom and dad shows that he definitely has colorblindness and his genotype is XcY
A Punnett square for the woman shows she is a carrier for colroblindness and her genotype is XcX
The chance of having a son is 50% and the chance of that son having colroblinness is 50%
Flagelle - 4
Pseudopod - 2
Autotroph - 8
Prokaryote - 1
Heterotroph - 3
Hope this helps ;)
Answer:
1/4
Explanation:
A heterozygous woman for both traits (RrFf) marries with a man with no freckles (ff) who can't roll his tongue (rr).
The cross is: RrFf X rrff.
The woman can produce the gametes <em>RF, Rf, rF </em>and <em>rf</em>
The man can only produce <em>rf </em>gametes.
<u>The possible offspring that can arise from the combination of those gametes is:</u>
- 1/4 RrFf Freckled, tongue-rolling
- 1/4 Rrff Freckled, unable to roll tongue
- 1/4 rrFf Not freckled, tongue-rolling
- 1/4 rrff Not freckled, unable to roll tongue
Answer:
A noncurler has a genotype cc.
Explanation:
If curlers always have at least one curler parent, it is possible being "curler" will be related to a dominant allele, in this example, "C". So, being "noncurler" could be a recessive trait. Noncurler can have one or both parents who are curlers, and this is concordant with a recessive inheritance if both parents are heterozygous (Cc) (with a probability of 25% of being "noncurler"). Also, it is possible if one parent is heterozygous and the other is homozygous for c (Cc x cc), this with a probability of 50% ob being "noncurler".
The Punnett square shows this clearly.
