Answer:
Explanation:
An organism is a body which is made up of many organ systems and parts. Organs constitute these organ systems. Then we will notice that these organs are made up of different types of tissues. Tissues are further analyzed under microscope to see millions of cells. By increasing the magnifying power, we can see that the cells are made up of further small molecules called atoms.
So starting form atom leads to further steps and development steps, an organism is formed. Atoms combine to form cells and each cell in the body perform the same function as our body as a whole perform. No smaller components can perform important functions of body other than cells. That’s y cells are known to be as the fundamental unit of life.
I think the answer is B, the interpretation of specific events as threatening or challenging.

However, there are effective strategies to cope with stress which include a sense of humor, relaxation, social skills, and social support.
Answer:
He could make a macromolecule which is made up of carbon and hydrogen only.
Explanation:
An atom a fundamental piece of matter that constitutes a chemical element.
A molecule is a group of atoms bonded together. It represents the smallest fundamental unit of a chemical compound that can participate in a chemical reaction.
The red balls denote the hydrogen and black balls denote the carbon. He could make a macromolecule which is made up of carbon and hydrogen only.
