b. Fourth degree trinomial
c. Sixth degree polynomial
d. First degree binomial
Answer: a. Third degree polynomial
Step-to-step explanation:-
Given polynomial :
We can see that the highest degree of x in the given polynomial is 3.
Therefore, the given polynomial is classified as a third degree polynomial.
b. heterotrophs.
c. thylakoids.
d. plants.
Answer: Heterotrophs
Explanation:
Organism that cannot make their own food and depends on the external sources for its energy are known as the heterotrophs.
They are dependent on the other organisms for their energy. They feed on the plants or animals for their energy.
Other than plants all the other organisms are dependent on food from other sources as they lack the ability to make food by their own.
Heterotrophs are the organisms that feed on other organisms to get energy to survive. Option B, Heterotrophs.
Organisms are classified into autotrophs and heterotrophs depending on how they get energy.
Heterotrophs need to feed on other organisms to get the necessary energy to survive. They do not produce their own food as producers do.
Depending on the food chain, heterotrophs might be either primary, secondary, tertiary consumers, and so on.
Also, depending on their source of food, they might be either herbivores (if they feed on plants) or carnivores (if they feed on animals). Omnivores can feed either on plants or animals.
In the exposed example, the organisms that cannot make their own food and must obtain energy from external sources are called heterotrophs.
The correct option is b. Heterotrophs

Answer: Yogurt contains good bacteria.
Explanation: Taking antibiotics for a longer duration of time kills the good bacteria present in the the gut of the human being. The gut of the human being consists of good bacteria as well as bad bacteria.
The good bacteria present in the gut of the human beings helps in the digestion of the food. Yogurt is a good source of good bacteria as it contains lactobacillus which is known as good bacteria that keeps the gut healthy.
