Is the correct order in a homeostatic feedback system stimulus, receoptor, control centre, effector?
Fantom [35]

Answer:

Correct

Explanation:

Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.

The Homoeostatic feedback mechanism has three basis components and they are independent to one another.

These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.

So, the order  in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.

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.

Why factors are cause of short-term climate change
laiz [17]

Answer:

6 factors that cause short term climate change...

Explanation:

Latitude - depends on how far or close to the equator it is

Ocean currents - Certain ocean currents have different temperatures.

Wind and air masses. Heated ground causes air to rise which results in lower air pressure. As it rises it cools and descends to the ground resulting in high air pressure.

Elevation. The higher up you are, the colder and drier it will be. When air rises it expands due to low air pressure which causes it to cool.

Relief. The differences in the elevation inland. As air is forced to rise over a piece of land, the temperature decreases and condensation increases.

Nearness to water. The water heats up and cools down slower than land does, having a moderating effect. On colder days, the water heats up the land, whereas on hotter days, the land is cooled down by the water.
