Take this example. If a population is sole comprised of one species of one type, and a disease comes along that wipes out this population, then everyone dies. However, if there is some variation, or resistance to this disease, then the resistant population will survive. This means that the species lives on!

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.

MaRussiya [10]

Answer:

Parasitic

Explanation:

The species that is described is a parasitic species. The reason why it will fall into this category is that its key feature is that it is entirely dependent on other organisms for its food. This type of species are not able to produce food for themselves, nor are able to get it from the environment, which is way they have evolved in a manner to use the other organisms. They find a host organisms, attach to it, and then they are extracting the nutrients out of that organism, thus classical parasitism. The extraction of the nutrients can be so severe that the parasitic species can actually kill systemically its host.

What major factors affected earth's changing climates?
Flura [38]
I just had this answer but it hasn't been graded. I put 1. Meteor impacts, 2. volcanic gases and 5. Milankovitch cycles. I didn't put earthquakes because I wouldn't think it would affect the climate changing since they just affect ground movement.

How does chlorine bond with sodium?
timurjin [86]

Both the sodium and the chlorine atoms need to obtain a stable electron configuration, thus, a complete outer shell of eight electrons.


Sodiums electron design is 2,8,1 and chlorines electron setup is 2,8,7. So all together for the two molecules of the two components to get a total external shell of eight electrons, sodium will give one electron to chlorine, and the chlorine particle will acknowledge the gave electron when responded with each other.

This outcomes in the sodium particle having an electron arrangement of 2,8 so is currently total. The chloride particle currently has an electron configuration of 2,8,8.

Since the molecules have moved toward becoming particles to end up stable, the Na+ and the Cl-particles draw in one another because of their contrary charges, which results in an ionic bond.


This is the reason sodium and chlorine cling to each other when responded.
