Match the functional groups with their structures:
evablogger [386]
The true answer of your question is :

OH : HYDROXYL GROUP

NH2 : AMINO GROUP

CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )

COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.

I hope you’ll understand everything, anyway if not i’m always here to help. ♥️

Write a hypothesis about how the interaction of tectonic plates may cause earthquakes.
iVinArrow [24]

Answer:

hope this helps

Explanation:

Techtonic plates interacting with each other would cause an earthquake because they are essentially the earth's foundation so by sliding together they would  cause rockfall and make a rumble which is basically what an earthquake is and when they interact its basically the earth moving so it would cause shaking and rumbling which is what happens in an earthquake

(Additionally) in the aftermath of an earthquake the plates are either moving or settling down which is why frequently after an earthquake there is a mini one following it

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.
