Answer:
1. There are five primary classes of antibodies, that are IgM, IgG, IgA, IgD, IgE.
2. IgM
Explanation:
The antibodies are proteins that are Y-shaped and are also called immunoglobulins. The antibody is produced when any pathogen attacks the body. There are five primary classes of antibodies, that are IgM, IgG, IgA, IgD, IgE. The antibody contains two heavy and two light chains. The IgM is a pentamer immunoglobulin. The IgG is contains two gamma heavy chains and two light chains. The IgA is mostly monomeric. The IgD have two delta heavy chains and light chains. The IgE contains two ∈ chains and light chains.
IgM is produced first. The IgA produced after IgM on mucosal surfaces. The IgG is present in serum. The all immunoglobulins IgM, IgA, IgD, IgE, and IgG are abundant in blood circulation.

Explanation:
Bioremediation is a branch of biotechnology that employs the use of living organisms, like microbes and bacteria, in the removal of contaminants, pollutants, and toxins from soil, water, and other environments. Bioremediation is used to clean up oil spills or contaminated groundwater.
Global warming occurs because of mainly, the pollutants that has been release out and made by the humans. In the choices above, the correct answer that will best suit in helping reduce global warming is letter b, reducing our fossil fuel use. It is because a fossil fuel contributes to global warming because it is a pollutant and harmful substance.
It will be perfectly horizontal. Since it’s a V-T graph, we will represent velocity on the y-axis (vertical axis) and time on the x-axis (horizontal axis).
Let’s think — a constant speed is one that doesn’t change.
At every point in time, the velocity will be 60, no matter what. On the other hand, time can’t be constant. Time will always be progressing, even though the velocity is the same.
This means the graph will only be moving along the time axis (the horizontal axis), showing how time has changed, but the velocity has not (the graph will always be at the point of 60mph for velocity, but won’t always have the same point for time).
If you need it, I can draw the graph as well.
