Answer:

Explanation:

1. Blood Plasma: this is made up óf water, salts and protein. And it makes up more than half of the total volume of blood

2. Erythrocytes are also known as the red blood cells which makes up some of the solid part of the blood. They are packed with haemoglobin which helps to carry oxygen and they also gives blood the characteristics red color

3. These are also called white blood cells that function in producing antibodies that fights infection. Some types are monocytes, neutrophils, eosinophils etc.

4. Blood platelets: these also make up a part of the solid portion of the blood. They aid in blood clotting preventing blood loss.

madreJ [45]

Answer:

because

Explanation:

It is an Incomplete question and the complete question is

All healthy, highly productive ecosystems provide which of these essential ecosystem services that involve gases in the atmosphere?

A. increasing carbon dioxide levels in the atmosphere by the action of plants and animals.

B. removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms.

C. removing water vapor from the atmosphere and using it to support plant growth.

D. removing methane from atmosphere and storing it's carbon and hydrogen in the tissues of organisms.

Answer:

The answer is removing carbon dioxide from the atmosphere and storing carbon in the tissues of organisms.

Explanation:

The water and carbon dioxide are byproducts and in which the photosynthesis removes CO2 from the atmosphere and replaces it with O2. In case of respiration it takes O2 from the atmosphere and places it with CO2.

To remove the CO2 it is directly put out of the air and burried it under ground saline aquifers this process is known as carbon capture and sequestration.

Sequestration is a process in which CO2 is removed from atmosphere and stored in the soil carbon pool. This process is mainly done through photosynthesis.

Why is the 3-dimensional shape of a macromolecule (ex: protein) important to know from the perspective of understanding
sineoko [7]

Answer:

A, B and C may be true

Explanation:

The three-dimensional structure (3D) of a protein, also known as tertiary structure, is critical to its function. In general, the 3D protein structure consists of alpha-helix and beta-sheets (secondary structures) associated through disordered coiled-coil regions. Genetic mutations may cause modifications in the 3D protein structure by modifying amino acids that are added to the growing polypeptide chain during the process of translation. In consequence, the relationships among amino acids (i.e., the intermolecular attractive forces that hold them together) may also be altered by these mutations. In general, mutations that generate amino acid changes at the active site of the enzyme will have a deleterious effect, thereby decreasing or inactivating protein function. However, there are situations where a mutation may be beneficial and can eventually increase the rate of reaction of a protein.
