The statements that are part of a biogeochemical cycle are : A , C , D
Carbon movements among the earth system spheres ( A )Phosphorous movements among the earth system spheres ( C )Oxygen movements among the earth system spheres ( D )The biogeochemical cycle is a cycle that represents the process/pathway through which important elements contained in living things/matter are successfully circulated in the ecosystem ( i.e. into the environment ).
Some of the biogeochemical cycles includes ; hydrologic-cycle , Nitrogen cycle, oxygen-cycle and carbon-cycle.

what cellular mechanisms allow human body cells to maintain these concentrations ?
Answers
Active transport: movement against a gradient To move substances against a concentration or electrochemical gradient, a cell must use energy. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the proper concentrations of ions and molecules in living cells.
Why do offspring produced sexually look similar to their
parents but not identical?
Answers
Answer:
In the process of sexual reproduction, haploid gametes produced by the meiotic division fuses to form a diploid zygote. A child inherits half of the genetic material from each parent. So, it may be they look alike but they are not identical to their parents.
Explanation:
I'm not an expert tho so if I'm wrong then dang
Answer:
Combination of the parents genetics
Explanation:
Every human being has 23 chromosome pairs (not regarding the chromosome pair for the gender). This mean that a human being has 23 chromosomes from their father and 23 chromosomes from their mother and by having those chromosomes in pairs the individual can have both the genetics of the parents and therefore have a mixture of both!
Within a given population of 4000 Vampire bats in Africa, the dominant allele frequency for long ear hairs is .2. What is the frequency of heterozygous bats within the population?
Answers
Based on the data provided, the frequency of heterozygous bats within the population is 0.32
What is the allele frequency?Allele frequency can be defined as the frequency in which a given allele for a gene occurs in a population.
Allele are alternate copies of a gene.
Alleles can be either dominant, recessive or co-dominant.
The allele frequency is given by the Hardy-Weinberg equilibrium equation given below:
p^{2} + 2pq + q^{2} = 1p + q = 1For the vampire bats:
p = 0.2
then; q = 0.8
p^{2} = 0.04
q^{2} = 0.64
The frequency of heterozygous bats within the population = 2pq
2pq = 1 - (0.04 + 0.64)
2pq = 0.32
Therefore, the frequency of heterozygous bats within the population is 0.32

The answer is D. Experimental investigation
Explanation:
There are three types of investigations in science namely: descriptive, comparative, and experimental investigations. Experimental investigations are those investigations that has to do with the testing of how one variable affects another.
In an experimental investigation, a variable called INDEPENDENT VARIABLE is changed to effect a response in another variable called DEPENDENT VARIABLE. In this question, a group of students is testing to see if earthworms prefer rough or smooth surface. Hence, they are testing to see how texture of a surface (rough or smooth), which is the independent variable affects the preference of earthworm. Hence, it is an EXPERIMENTAL VARIABLE.

The sun shining on a tidal pool during a hot day heats the water. As some water evaporates, the pool becomes saltier, causing.
Answers
As water evaporates off salt water, the water gets saltier, and dissolved oxygen in the water reduces.
Dissolved oxygen and solute concentrationThere is an inverse relationship between the dissolved oxygen in water and the concentration of solute.
Thus, as water evaporates off the tidal pool, available free oxygen decreases accordingly just as the water becomes more salty.
In other words, the more water in a solution, the more free oxygen, and vice versa.

A human hair cell is unable to transcribe the DNA sequence coding for black hair color. What is one possible effect on the hair produced by this cell?
Answers
Answer:
The hair produced by the cell will not have the BLACK COLORATION
Explanation:
In the process of gene expression, a gene, which is the segment of DNA that encodes useful products, is transcribed into a mRNA molecule. The mRNA is then translated into a protein, which is responsible for the observed traits or characteristics.
In this case, a human hair cell is unable to transcribe the DNA sequence (gene) coding for black hair color (trait). This means that the gene that encodes hair color protein cannot be transcibed, hence, the protein will not be produced in that cell.
If the protein responsible for black hair color is not produced in a cell, the hair produced by such a cell will not be BLACK.

Answers
Answer:
C. clean air and water
Explanation:
The reason why this is NOT a benefit of biodiversity is because Plants and Animals really like to mess things up, you know, they really just don't care about what they're destroying, so if there is a crocodile in the water, then it won't care about just playing with some mud, that's why, they make the water dirty, specially while attacking land animals that come to drink the water. Another thing is that they can just p.o.o.p which will not make anything better.
so hence, your answer is C. Clean air and water
