Answer:

The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. ... While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.

What are the three stages of the cell cycle?

What might happen if the gametes of a species had
mario62 [17]

Answer:

<em>The chromosome number will not be constant and the person would die.</em>

Explanation:

During gamete formation, half of the chromosomes arise from one parent and the other half from the other parent. This is possible due to the process of meiosis.

If during gamete formation, the number of chromosome does not get reduced, then after fertilization the gamete will have double the number of chromosomes as compared to the parents. Hence, the chromosome number of the person will not remain constant and he/she would die.

Genetically-modified organisms (GMOs) have included corn crops engineered to produce a natural pesticide to kill a certain insec
Dmitrij [34]
A downside to this mutant corn wohld be that it would give rise to a presticide-immune strain of the certain insect.

All the non-immune bugs would die, leaving the few immune ones to reproduce. That would result in a overpopulation of immune super-bug that would still be able to go ham on the large, GMO corn, like nothing happened, and still go on to affect native plant populations. That can become a huge problem.

Hope that helped!

Justify your answer by filling in the blanks. Both parents have white fur. way that this can happen is if their genotypes are bo
MissTica

Answer:

Both parents have white fur. <em>The only</em> way that this can happen is if their genotypes are both <em>homozygous (bb)</em>. Therefore, both parents pass the (b) allele to every offspring. When you combine two of these alleles, the resulting genotype is <em>(bb);</em> therefore, the resulting  offspring have white fur.

Explanation:

A homozygous trait can be described as a trait in which both the alleles for a gene are similar. A heterozygous trait can be described as a trait in which both the alleles of a gene are different. If an allele masks the effect of another allele, it is said to be dominant. the allele that gets suppressed is termed as recessive.

Hence, for a recessive trait to occur both the alleles of a gene should be homozygous recessive.

The punnet square for the above cross is shown below:

        b       b

b       bb     bb

b       bb      bb
