Tha main components in blood are the plasma, red blood cells, white blood cells, and blood platelets.

Plasma is like the main component that makes up most of the blood. It has a light yellow color and it carries many substances including nutrients, waste, hormones and more.

Red blood cells are the reason why blood is red in color. They have a hemoglobin inside them which can help carry oxygen for the tissues and organs. In order to maximize the oxygen carrying capacity, they don't have a nucleus.

White blood cells can be divided into phagocytes and lymphocytes. Their main function is to protect us from diseases. Phahocytes and engulf and digest bacteria, while lymphocytes can produce antibodies.

Blood platelets can cause blood clotting which can stop us from bleeding forever. They're not cells, but just fragments of cells. They also don't have nucleus since they're not complete cells.

Leokris [45]

Answer:

<h2><em><u>Base</u></em><em><u> </u></em><em><u>isolated</u></em><em><u> </u></em><em><u>system</u></em></h2>

Explanation:

<u>Fixed based system:- </u>

A fixed-base building (built directly on the ground) will move with an earthquake’s motion and can sustain extensive damage as a result. 

<u>Base isolated system:-</u>

A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure).

<em><u>Hence</u></em><em><u>,</u></em>

A sample of soil from a C horizon is light brown in color and has a high content of a mineral called feldspar. Which of the foll
vaieri [72.5K]

Answer: C. The C horizon is very deep.

Horizons are the layers of soil develops as a result of soil formation. Horizon lies parallel to the earth surface. Each horizon differs from the other on the basis of amount or organic matter present, color of the soil, texture of soil and other components making up horizon, and amount and type of minerals present in the soil.

C horizon is the horizon that lies deeper region of the collective soil horizon. It consist of unweathered or partially weathered rocks or their aggregates. Therefore, it retains the original chemical composition of the parent rock. This results in the higher mineral content as compared to other horizons. This horizon also lacks the organic matter as no or very little decomposition activity of plant and animal matter takes place. Therefore, color of soil in this horizon in the absence of organic matter remains light.

Hence, a sample of soil from a C horizon is light brown in color and has a high content of a mineral called feldspar is because of the fact that the C horizon is very deep.
