The chief difference between arteries<span> and </span>veins<span> is the job that they do. </span>Arteries<span> carry oxygenated blood away from the heart to the body, and </span>veins<span> carry oxygen-poor blood back from the body to the heart.
Another difference would be v</span><span>eins have valves and arteries do not. In arteries, blood flows in the right direction because of the heart pumping it forwards at high pressures. The lower blood pressure in veins means that valves are needed to stop blood flowing backwards (for example, in veins in the legs, blood needs to flow upwards against the pull of gravity).</span>
B) Melting ice would increase the growing season because the temperatures would increase, animals living in certain areas would migrate to others, and certain species that lived on the ice would die.
1. agglutination of particulate matter, including bacteria and viruses,
2. opsonisation or coating over bacteria to facilitate recognition and phagocytosis by the phagocytes and
3. neutralization of toxins released by bacteria.
Answer:
The first three steps are related to the construction of Punnett squares and the fourth step is not part of the square construction since information related to the phenotype It can be established as a conclusion or result of the genotypes obtained.
Explanation:
Punnett squares is designed to predict the mathematical probability of genotypes in the offspring, according to the genotype of the parental generation, and records only information related to this genotypes.
Taking as an example the crossing between a dominant homozygous (AA) individual for an character and a recessive one (aa), a Punnett square can be constructed:
A. All possible combinations of alleles in the gametes produced by one parent are written along the top edge of the square
:
♀️\♂<u> A A </u>
B. All possible combinations of alleles of the other parent are written along the left edge of the square.
♀️\<u>♂</u><u> A A </u>
a
a
C. All possible genotype are written inside the boxes within the square, as they might appear in the offspring
♀️\<u>♂</u><u> A A </u>
a Aa Aa
a Aa Aa
<u>The result of the crossing of an individual with AA genotype and another aa is a offspring of Aa hybrid individuals, according to the information obtained from the Punnett square</u>.
Information related to the phenotype is not part of the Punnett square, but from the genotype a conclusion can be drawn and established, which can be written below, and not on the sides of the square. In this case, the phenotype would be 100% of individuals exhibiting the dominant character A.
