Correct Answer: Neuron
Correct Answer: Glycolate
Correct Answer: Both A & B
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: FALSE
Explanation:
Mushrooms 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.
Correct Answer: Mitosis
Explanation:
Pollen is a male plant gamete. When microspores produced after meiosis process on microsporangia of male gametophyte undergo mitosis and forms pollen grains.
