Question

A) Answer the following questions:
1. Explain how soil is formed?
2. What will happen if there are no platelets in
the blood ?
3. Why is it necessary to excrete waste products
?
4. What are the components in the blood​

Answer 1

Explanation:

1. Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.
2. Platelets are responsible for clotting of blood. If there are no platelets, the blood would not clot in case of an injury. This will lead to excess blood loss and can even lead to the death of a person.
3. The waste materials produced during the metabolic activities are toxic to the body and must not be accumulated inside, and therefore it has to be excreted out from the body by the process of excretion.
4. It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues

Answer 2

Answer:

A.1.Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.

A.2.Platelets, also known as thrombocytes perform primarily the function of clotting of bloods. If there are no platelets in the blood, a coagulum or a clot will not form and hence, this will result in unstoppable bleeding leading to severe blood loss and ultimately death of the individual.

A.3.The waste materials produced during the metabolic activities are toxic to the body and must not be accumulated inside, and therefore it has to be excreted out from the body by the process of excretion.

A.4.It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues.
