Answer:

The first immunoglobulin to arrive is M, IgM

Explanation:

Immunoglobulins are the molecules that intervene in defense against microorganisms, foreign cells and against substances that can cause allergies. They are also known as antibodies. IgM is specific and is the first antibody that appears in primary infections, so its value and quantity is very important to diagnose an infection.

Explanation:

Immunoglobulin M is the first antibody produced on initial exposure to an antigen. It is also known as IgM.

It occurs as a primary response to the antigens against a particular baterium or virus. It is pentavalent in nature and has ten binding sites for antigens.

Therefore, it is concluded that when the body identifies a bacterium or a virus, it releases the antibody IgM.

Katarina [22]

Answer:

single bond= 1 sigma bond

Plan an investigation using solid and liquid water to show that thermal energy is not the same as temperature.
algol [13]

The investigation using solid and liquid water to show that thermal energy is not the same as temperature is:

  • Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.

<h3>What is the response to the experiment above?</h3>

The response is No, because the lake is known to have a lot more particles than the glass of water and so they will not have the same  thermal energy.

Note that the temperature is seen as the an average and thermal energy is seen to be the total. A glass of water can be able to have the same temperature as what we call Lake Superior, but the lake has a lot of thermal energy due to the fact that the lake has a lot of water molecules.

So the investigation using solid and liquid water to show that thermal energy is not the same as temperature is Place a glass of water and a lake and both should be at the same temperature, find out if do they have the same amount of total thermal energy.

Noah and Nina are 15 m apart in a closed room. Noah says the same sentence twice. The first time, Nina does not hear the sound,
In-s [12.5K]

The air molecules in the compressions of the second wave are denser, so the sound is louder.

<h3>What is a sound wave?</h3>

Sound waves are longitudinal waves that travel through a medium like air or water.

In a closed room, Noah and Nina are sitting 15 m apart.

As Noah says the same sentence twice, Nina does not hear the sound the first time but she does hear the sentence the second time.

This happens as the air molecules in the compressions of the second wave are denser. As a result, the sound is louder.

The correct option is ''The air molecules in the compressions of the second wave are denser, so the sound is louder''.
