b. In 1979, the estimated elephant population was 1.3 million and in 2007 it was 640,000. By approximately what percentage did t
saveliy_v [14]

Answer:

The initial amount, 1.3 million = 1,300,000 is the 100%.

now, 640,000 is a given percentage (lower than 100%) of that.

How we can find it?

suppose that 640,000 represents an x%.

Then we have that the quotient between the actual quantities and the percentages must be the same

(640,000/1,300,000) = x%/100%

x% = (640,000/1,300,000)*100% = 49.23%

Then the percentage declined is:

100% - 49.23% = 50.77%

The other question can not be answered with the given information.

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.

Fynjy0 [20]

Answer:

The teeth in the mouth bite off a piece of food.

The teeth continue to break the food into smaller pieces.

Saliva rushes into the mouth and mixes with the broken-down food.

The food travels down the esophagus.

The muscles of the stomach churn the food and continue to break it down.

The broken-down food, called chyme, enters the small intestine.

The remaining food passes into the large intestine. Water is absorbed from the large intestine and the rest of

the material is stored as solid waste until it is excreted from the body.
