- Question
Is a mushroom an autotroph?
Options- A. TRUE
- B. FALSE
- Correct Answer
- FALSE
ExplanationMushrooms are heterotrophs. They are not plants or autotrophs.
Every living thing that exists need energy in order to live. This energy ultimately comes from the sun, and only plants, or autotrophs, can directly use this energy to make food. Those organisms that cannot harness the sun's energy are known as heterotrophs.
Mushrooms belong to kingdom Fungi and are heterotrophs because they decompose and consume nutrients from the soil. They are not green so they cannot photosynthesize
For this reason, mushrooms and all other fungi are heterotrophs. - 1. The process of bones increasing in width is known as

Correct Answer: appositional growth
Correct Answer: the skeletal system creates the connective tissue and tendons that allow the body to move
Explanation:
One reason the skeletal system is important is because the skeletal system creates the connective tissue and tendons that allow the body to move.
Correct Answer: haemoglobin
Explanation:
Oxygen in our blood is transported by a protein named Haemoglobin.
Correct Answer: M
Explanation:
Longest and shortest phases Of cell cycle:
Shortest Phase - M phase or Mitotic phase.
Longest phase - G1 phase of the Interphase
Longest and shortest phases During Mitosis:
Longest Phase - Prophase
Shortest Phase - Anaphase
Correct Answer: Bacteria
Explanation:
The process by which bacteria convert nitrogen gas (N2) into ammonia (NH3) is called Nitrogen Fixation.
The conversion of nitrogen from one form to another in the nitrogen cycle is carried out primarily by Nitrogen Fixing Bacteria such as Azotobacter.
Correct Answer: All the above
Explanation:
Nitrogenous base: A molecule that contains nitrogen and has the chemical properties of a base.
The nitrogenous bases in DNA are
Adenine (A),
Guanine (G),
Thymine (T), and
Cytosine (C).
Whereas the nitrogenous bases in RNA are the same, with one exception:
Adenine (A),
Guanine (G),
Uracil (U), and
Cytosine (C).
Correct Answer: Both A & B
Correct Answer: Glycolate
Correct Answer: Neuron
Correct Answer: Water
Explanation:
Water is the important nutrient all organisms need. Humans has almost 60% of their body weight is water. Some organisms have 90% of their body weight is of water.
