Is the heme molecule attached to hemoglobin during the primary level or tertiary level of organization?

Biology
1 answer:
djyliett [7]3 years ago
3 0

Answer:

Tertiary.

Explanation:

Primary structure of proteins refers to the order of amino acids that make up the protein. The heme is an nonprotein non-amino acid, so it is not involved at this stage.

Tertiary structure of proteins is the overall 3-D folding of the protein (it comes after secondary, which involves folding into a repeated pattern). The heme bonds to its correct position on the hemoglobin during this stage and helps in correct folding.

Vlad1618 [11]

Answer:

E. The length of cells in the elongation and mature zones would be larger in the control group.

Explanation:

The length of cells in the elongation and mature zones would be larger in the control group this is because of the increase in the solute concentration of the hydroponic growth medium which excluded the roots.

This reduces the amount of water that moves into the root system of the plants and nutrients which imitate drought conditions, this imposed drought leads to a decrease in the plant growth.

Which of the following statements is true? Select all that apply. Capillaries have a higher resistance to flow than either arter
Nitella [24]

Answer:

  1. Blood travels at a higher velocity in arteries than in veins.
  2. The volume of blood flow in the arteries and arterioles is greater than the volume of blood flow through the capillaries
  3. Blood pressure is higher in arteries than in veins.
  4. The total cross-sectional area of the capillaries is greater than the total cross-sectional area of the venules and veins

Explanation:

The lumen of arteries is larger than that of arterioles and capillaries. However, even though they have a smaller lumen compared to veins, their walls are thicker to bear the pressure of the blood as it is pumped by the heart to the tissues. Therefore the blood pressure and velocity of blood in arteries (that pump blood away from the heart) is higher than in capillaries and veins. Veins take blood back to the heart from tissues hence this blood is under lower pressure and velocity. This is why veins have valves to prevent the back-flow of blood against gravity.

Due to the large cross-section area of capillaries the blood flow is here is slower hence giving time for blood to linger a bit so there is an exchange of materials between the blood plasma and the interstitial fluids that nourish the cells.

List three methods used to prevent the evaporator from becoming too cold and freezing
olga55 [171]

The first one is have the refrigerant level checked by a qualified professional. The technician will be checking any possible leak, damage and conduct test on the system. Second is to ensure airflow. Change the filter regularly, usually about every three months or maybe monthly, depending on its usage. Have the coils cleaned by a professional if it is already dirty. The third method is to not use your air conditioner when the outside temperature is below 60º. You will be saving energy and money on utility costs by just opening the windows on cool days.
