Answer:

The correct answer is option A (Dead plants and animals).

Explanation:

Fossil fuels are hydrocarbon-containing materials like natural gas, fuel oil, coal which act as a source of energy. These fossil fuels are formed from the remains of dead animals and plants of Carboniferous Period about 360 to 286 million years ago.

At that time the remains of plants and animals along with micro-organisms were decayed which were later covered by sand and silt and trapped it under the rocks. Over time heat and pressure compressed it and changed it into coal, oil and some trapped pockets of gases known as natural gas.

Thus, option A (Dead plants and animals) is the correct answer.

Severe anemia may trigger an adaptive conversion of:
goldfiish [28.3K]

Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.

Anaemia is defined as the decrease or the reduction of the oxygen carrying content of the blood which are the red blood cells.

These red blood cells and other blood cells which include the white blood cells and the platelets are produced in the body by the bone marrows by a process called haemopoiesis.

The bone marrow is divided into two:

  • yellow bone marrow and
  • red bone marrow.

The red bone marrow is made up of stem cells which can be converted to red cells when the need arises while yellow bone marrow is made up of fat.

During health conditions such as anaemia, there is increase in the need of red blood cells by the body.

There is usually the conversation of yellow bone marrow to red bone marrow to compensate for the increased demand of red blood cells.

This conversation is called an adaptive conversation.

Therefore,Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.

ivann1987 [24]

Answer:

The correct answer is: lets the air get inside the lungs.

Explanation:

The process of ventilation, or breathing, consists of two parts: <u>inhaling and exhaling.</u>

Inhaling is the name of the process that is responsible for the air entering the body by the respiratory tract. Exhaling is the opposite, it lets the air out. Both are equally important since they allow the gas exchange necessary for the oxygenation of the blood.

When inhaling, the diaphragm and the external intercostal muscles contract. This pulls the ribcage upwards and outwards, which increases lung volume while decreasing the air pressure inside.
