How is the degree of oxygenation of the blood related to skin color?

One of the contributing factor to skin color is blood. Blood is responsible for the rosy color of skin. It is influenced by how much blood flows in the capillaries, how much hemoglobin there is in the blood and the degree of oxygenation of arterial blood.

When blood is well-oxygenated the skin gives off a more reddish color or rosy color. When oxygenation is poor the skin becomes bluish, which is cyanosis.

If a hypothetical cell contained 1% saline and 5% glucose, approximately what
liraira [26]

The hypothetical cell will approximately contain 94 percent (94%) of water.

  • If a cell is placed in a hypertonic solution that contains more concentration of solutes (such as salt and glucose) than the cell, then it will shrink because water moves outside the cell.

  • If a cell is placed in a hypotonic solution that contains more concentration of water than the cell, then the water will move inside the cell.

  • Finally, if a cell is placed in an isotonic solution, which contains the same concentration of solute and solvent as outside the cell, there will be no change in the cell and the solution.

  • In this case, the percentage of solutes is equal to 5% (glucose) + 1% (salt) = 6%, so the remmaining porcentage of water is equal to 94 percent (94%).

Explain why crops in the arctic grow larger than normal during the summer months
Romashka-Z-Leto [24]

Answer:

More sunlight, more photosynthesis

Explanation:

This is because when the sunlight hits the leaves, it allows photosynthesis to occur. But when you have extended periods of sunlight, like summer, it causes photosynthesis to continue for a longer time, which causes rapid energy storage. This makes excess food for the plant which gives the plant more energy for growth and pollination.

Hope this clears it up for ya:)

The NADPH generated by the pentose phosphate pathway primarily serves as a
Igoryamba

Answer:

Option-A

Explanation:

Pentose phosphate pathway is the alternative pathway taking place in both eukaryotes and prokaryotes parallel to the glycolysis.

The pentose phosphate pathway forms the electron carriers called NADPH and the ribose-5 phosphate.

The NADPH is formed in large amounts through this pathway which contains a very high amount of energy. NADPH can donate its hydride ions, therefore, it can be involved in the reaction where it can donate energy in the form of hydrogen and electron.

The NADPH is therefore involved in the formation of reducing biosynthetic pathways like fatty acid synthesis, cholesterol synthesis, and bile acid synthesis.

Thus, Option-A is the correct answer.
