List 5 uses for proteins in the cell.

sasho [114]

Answer:

Protein has many roles in your body. It helps repair and build your body’s tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance. Finally, they keep your immune system strong, transport and store nutrients and can act as an energy source, if needed.

Compare the movement of oxygen and carbon dioxide across the cell membrane. (4 marks)

lana66690 [7]

Answer:

Molecules naturally disperse from areas of higher concentration to lower concentration.

As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.

The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.

These movements require no energy (in the form of ATP) on behalf of the cell.

A planet is inhabited by creatures that reproduce with the same hereditary patterns seen in humans. Three phenotypic characters

Zigmanuir [339]

Answer:

For the first experiment, the recombination frequency is shown below. This experiment comprises the cross between the Tall and the Antennae.

Tall-antennae - 46% - Expected

Dwarf-no antennae - 42% - Expected

Dwarf-antennae - 7% - Recombinant

Tall-no antennae - 5% - Recombinant

Total = 100%

For the recombinants, the recombination frequency is:

= 7 + 5 = 12%

Thus, the recombination frequency between the T and A genes is 12%.

For the second experiment, the cross takes place between the heterozygous antennae and the upturned snout. The results are shown below:

Antennae-upturned snout - 47% - Expected

No antennae-downward snout - 48 % - Expected

Antennae-downward snout - 2% - Recombinant

No antennae-upturned snout - 3% - Recombinant

Total = 100%

The recombinant frequency is = 2 + 3 = 5%

Thus, the recombination frequency between the A and S genes is 5%.
