Answer:Maternal and paternal chromosomes are randomly distributed on either side of the metaphase plate. So for each pair there's a 50/50 chance as to which side the homologs will go on (8.17). We have 23 pairs each with 50/50 probabilities. That works out to 223 possible combinations of gametes from one human individual.

Where does osmosis take place
Sav [38]

Answer:

In Gastrointestinal system:

When we eat food or drink water, it travels from our mouth, down our oesophagus and into our stomach. In the stomach, the food is broken into tiny pieces that are mixed with stomach liquids. This mush of food and stomach liquids is called chyme. The chyme travels into the small intestine. This is where osmosis takes place.

In our Kidneys:

Our kidneys keep blood and tissue fluid (internal environment) 'clean' by removing urea, excess water and other wastes and excreting them. This controls the amounts of dissolved substances in blood and tissue fluid, a process called osmoregulation. If tissue fluid becomes too concentrated, cells will lose water by osmosis and become dehydrated and if it becomes too dilute, cells will take in excess water by osmosis.

How is it possible that organisms with the same phenotype can have different genotypes?
Yuri [45]

Answer:

I think it is C (<em>Different genetic makeups can lead to the same traits.)</em>

Explanation:

An organism's genotype is the combination of alleles found at a particular gene. The phenotype is how theses alleles are expressed to form a trait.

In a diploid organism there are two alleles for every gene. In simple Mendelian traits. one allele is dominant over the other, which is recessive. That means, that the phenotype displayed will be associated with the dominant allele whenever it is present.

phetotypes is physical looks. people look similar but have different genotypes you get what im saying, because one genotype gets masked over the other. like blond and black come together black will win but blond is still in genes so thats how this would work ;)  

hope i helped
