Compare and Contrasts Biotic Factors and Abiotic Factors. What are they?
How are the alike.
How are the different?

Answers

A biotic factor is a living thing that has an impact on another population of living things or on the environment. Abiotic factors do the same thing, but they are non-living. Together, biotic and abiotic factors make up an ecosystem. To survive, biotic factors need abiotic factors.

Biotic factors are living organisms that typically contribute in some way to their environment. Some examples of Biotic factors include plants, animals, cells and they are typically producers, consumers or decomposes. Unlike Biotic factors, Abiotic factors are the non-living part of an ecosystem. They are typically chemical or physical, some abiotic factors include water, sunlight, soil, and temperature. Both Biotic and Abiotic factors are required in an ecosystem to properly function.

Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes. While pouring an unknown chemical into a beaker, she accidently splashed some of the chemical in her eyes. What should Maria immediately do next?

Answers

Answer:

She should immediately rinse or flush her eyes with water.

Explanation:

One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.

Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.

Answer:

proceed to the eye wash station, open her eyes, and rinse them for at least 15 minutes
