What happens in animal cells when mineral concentration is high and low in solution
slamgirl [31]

Answer:

Diffusion occurs when there is movement of minerals from an area of higher to lower concentration, till equilibrium is obtained.

Whereas Osmosis is the movement of solvents rather then the solute, from a solution of lower to a solution of higher concentration with the help of semipermeable membrane.

Explanation:

Diffusion is the movement of substances from area of higher concentration to an area of lower concentration of minerals, which mainly results in animal cells. Whether solute or solvent, diffusion occurs for both. Diffusion does not requires any semi permeable membrane. Diffusion occur in all state of matter, that solid, liquid and gas, whereas osmosis occurs only in liquid state. Osmosis requires semipermeable membrane and rate of which is related to concentration of solute dissolution in solvent medium. Only movement of solvent medium takes place. Classical example of osmosis is exhibited by cell membranes of animal cells. On the other hand diffusion is the spreading of perfume or fragrances to the external air.

Feedback mechanisms have evolved that maintain homeostasis. Describe how homeostasis is maintained through feedback. In your ans
Mrac [35]
Homeostasis is maintained through feedback because when one certain parameter of your body goes out of the homeostatic bounds, feedback mechanisms will message this back towards the regulatory mechanisms which are responsible for homeostasis maintenance in the first place. Another thing, other than death, which can happen would be a higher bodily temperature for example.

In an individual of genotype aa, where are the a and a alleles physically located? view available hint(s) in an individual of ge
Alex787 [66]

Answer:

One allele is on one chromosome, and the other is in the same position (locus) on the homologous chromosome.

Explanation:

The genotype of an organism refers to the genetic makeup or complete set of genes. The genes control the trait of an organism and exist in an organism in their alternative form called alleles.

Since the alleles are the alternative form of a gene, therefore, they must be present at the same position called a locus.  

These alleles are present on the homologous chromosome in which each homologous chromosome is contributed by each parent. Therefore when the genotype is aa then a and a allele will be present on homologous chromosomes in the same position.

Thus, the selected option is correct.

An unlabeled hierarchical diagram of various astronomical bodies is shown below. The labels A, B, C, and D can be used to repres
Nady [450]
All planets have these same layers (From deepest to shallowest, inner core then the outer core, then the mantle, and lastly the crust. A good example is the Earth) that is shown in the diagram, even the sun has all the layers I just listed.
But, some planets I can think of are Mars, Venus, Moon, and the Earth of course.

Layer C. sounds like it could also represent Layer D, since they are so close.

P. S. I did my best to try to answer this.
