Answer:
Carbs - provide your body with energy.
Lipids - serve as structural components of cell membrane, function as energy storehouses, and function as important signaling molecules.
Protein - helps with growth and maintenance of tissues, enzymes that cause biochemical reactions in and out of your cells, some proteins are hormones so it acts as a messenger the aid communication between your cells, tissues, and organs. And many other thing that are a google search away.
Nucleic Acids - hold storage and expression of genetic information
Answer:
when one muscle is contracted, the other muscle from the pair is always elongated. for example, the biceps and tricep muscles work together to allow you to bend and straighten your elbow. when you want to bend your elbow, your bicep muscle contracts. and at the same time tricep muscles relaxes.

The answer will be Endoplasmic Reticulum (ER).
It is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell.
Well, to make it easier, endoplasmic reticulum is actually a fancy way of saying "cellular highway". I will explain to you why. I always like to study BIOLOGY relating our activities and our stuff.
Okay, let's push aside cells. Let's think of us, humans. We can't stay in one place, we gotta moving all around the city. What do we use for moving around the city: either roads or sidewalks or footpaths.
Just like that, a cell also has a medium or road or a channel where all the substances can move around the cell. Well, its ER! So, from now on, everytime you are struggling with this difficult, L O N G word, just replace it with "cellular highway". The ER is like a water pipe, too. Water flows through it. Here, cellur substances flow through it. The ER is connected to the nucleus.
SUMMARY:
1# ER aka Endoplasmic Reticulum is a kind of channel that carries substances, such as proteins, oil droplets, water, to other parts of the cell.
2# Try thinking it easy: replace it with "cellular highway".
3# It is much like the roads or sidewalks, we walk on.
It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum. Gypsum is commonly associated with rock salt and sulfur deposits.
