Plastic is a non-biodegradable and non-point source of pollution because it cannot be broken down into degradable materials by micro-organisms. It comes from man-made substances and industries therefore, it is non-point pollutant.
What is Plastic?Plastic is a non-biodegradable and non-point pollutant. Because, the enzymes in the microorganisms cannot break down the waste into bio-degradable materials as microbes cannot recognize the bonds that hold these polymers together. Eventually, the polymers in plastic may break down, perhaps after hundreds of years. But after a long time, the damage is already done to the environment.
Nonpoint source of pollution comes from oil, pet waste, herbicide, bacteria, sediment, and any other contaminant that ends up on the ground naturally or from human activity.

(Select the TWO correct answers).
Class
Domain
Genus
Species
Kingdom
Phylum
Order
Family
Answer:
Scientists use a two-name system called a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species
An organism’s scientific name consists of which two taxonomic groups, genus, and species. The correct options are c and d.
What are taxonomic groups?Taxonomic groups are the groups that contain different groups in which the organism are divided. These are arranged from higher to lower groups. The highest group is the kingdom.
Kingdoms are divides of the different organisms of the earth. Taxonomy is organizing different organisms in a line so, that it will be easy for their studying.
The two taxonomic groups that come in last are genus and species. Genus and species make the scientific name of the organism. The genus contains animals that are most similar to each other. Species are similar organisms, that can breed with each other.
Therefore, the correct options are c, Genus, and d, Species.

i put b in my test and it was wrong
and did it again and got it right
According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
The answer would be:
The object pushing back on you.
