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.
Yes because it will warn you so the fire does not spread.

The correct answer is A. Prevent and reduce waste.
Explanation
Environmental sustainability is the balance that is generated through the harmonious relationship between society and the surrounding nature. This implies achieving development without threatening natural resources and without compromising those of future generations. In that sense, it is considered environmental sustainability, beyond being a specific area of human development, should be the axis of any form of development. Additionally, one of the ways individuals can contribute to environmental sustainability, it by reducing and preventing waste because human waste harms the environment, for example, plastic pollutes natural environments and affects the species that live there, breaking the harmonious relationship that is necessary for environmental sustainability. So, the correct answer is A. Prevent and reduce waste.
