Answer:
Option c
Explanation:
In experimental design, there are lots of test to certify the essence of the design. When there exist an independent variable, every measure of control is applied to it to test if it measures the expectation ,so there can't be one or two control measure not applied to the independent variable, we have to test every respective attribute of the control measure, we have randomly apply different theories to see if the control measure with its independent variable meets standards that is why Option C is not a requirement
Answer:
<h3>IgA, IgM and IgG</h3>
Explanation:
Immunoglobulins are antibodies. They're proteins that are fabricated by the immune system after exposure to an antigen (something harmful to your body that causes an immune response). Immunoglobulins, or antibodies, fight off germs, illness, and diseases. They circulate throughout the body and can be found in your blood, sweat, saliva, and even in your breast milk.
A newborn does not yet have a mature immune system and is often unable to mount an effective immune response to combat antigens. Newborns are generally protected by the antibodies they receive through the placenta before birth and through their mother's breastmilk after birth. These antibodies will be the same ones that are circulating in the mother's system, which will include antibodies to the microorganisms in the mother's home environment and other places she frequents. Therefore, babies generally have antibodies to the germs in their own homes.
he baby has some immunoglobulins at birth, but the sheltered intra-uterine existence limits the need for learned immune responses to specific antigens. There are three main immunoglobulins, IgG, IgA and IgM, and of these only IgG is small enough to cross the placental barrier. It affords immunity to specific viral infections. At birth the baby's levels of IgG are equal to or slightly higher than those of the mother. This provides passive immunity during the first few months of life.
IgM and IgA do not cross the placental barrier but can be manufactured by the fetus. Secretory Immunoglobulin A (IgA) is a special immunoglobulin. It's the main antibody found in breast milk and is considered the most important immunoglobulin in breast milk. IgA is important because it coats and seals the child´s respiratory and intestinal tract to prevent germs from entering the body and the bloodstream. The IgA antibodies can protect from a variety of illnesses including those caused by bacteria, viruses, fungi, and parasites.
Answer:
In the first place, there are some particular interest groups that can influence lawmakers´decision-making. In the first place, particular lobbies - Wall Street corporations, big donors to campaign, foreign companies, unions - can put pressure on congressmen or congresswomen in order to get bills passed that serve their interests or give them an advantage, or they can court them through donations, promises of votes, etc. Secondly, Congress members put a lot of attention to public issues that are extremely sensitive to their voters and usually tilt toward the position of a majority. Thirdly, there are sometimes issues that are regarded as by party leaders as crucial and party loyalty is demanded or expected when voting in the floor takes place. And fourthly, sometimes ongoing or future events are so important that they determine outcomes; for example, very few Congress members - both Democrats and Republicans - voted against giving president George W. Bush powers to go to war in Iraq; many were afraid of being called "unpatriotic."

Answer:
As you increase in elevation, there is less air above you thus the pressure decreases. As the pressure decreases, air molecules spread out further (i.e. air expands) and the temperature decreases. If the humidity is at 100 percent (because it's snowing), the temperature decreases more slowly with height.
