Answer:
Most macromolecules are made from single subunits, or building blocks, called monomers. The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts.
It’s characteristic is the need for energy

Answer:
The correct answer is - production.
Explanation:
If a cow does not milk on schedule it creates stress conditions and leads to several physiological changes which lead to the release of a hormone. This hormone result in lower milk production also affects negatively on her immunity.
The stress cause release of estrogen, and prolactin hormones with other corticosterioids that result in decreases in the number of cytokines and decrease innate immunity of the cow.
Warm air holds more moisture than cold air.
When the air has reached "saturation point" (ie.
it cannot hold any more moisture), it is more likely to cause precipitation as the oversaturated air forms moisture droplets that fall as precipitation.
One of the major causes of precipitation is when warm air cools rapidly As the warm air cools, it loses its ability to retain moisture and becomes saturated, thus creating precipitation.
