Explanation:
There are two classes of nuclear reactions which are:
- Nuclear fission
- Nuclear fusion
In nuclear fission, a radioactive isotope which has a heavier nucleus spontaneously disintegrates(breaks up) into 2 lighter nuclei and several neutrons with a large release of energy.
A nuclear fusion occurs by the combination of small atomic nuclei into larger ones with the release of a large amount of energy.
I hope you can make the best choice from this explanation.

Answer:
The 5' and 3' polarity restriction
Explanation:
Discontinuous replication is when synthesis of new DNA molecule takes place as a series of short fragments that will subsequently be joined together.
These fragments are called the Okazaki fragments.
DNA synthesis takes place from 3' to 5' end. However due to 5' and 3' polarity. The replication has to be discontinuous due to the synthesis happening backwards and okazaki fragments being formed.
Nitrogen-fixing bacteria change nitrogen into a form of soluble nitrates that plants can use ...the air is 80% nitrogen but it is in N2 form which plants cannot use
Receptors detect changes in the environment. For a stimulus to elicit a response, certain cells must have an appropriate receptor. Stimulation of the receptor initiates a specific signal pathway.
It is defiantly not a, because only part of the park was burnt. It wouldn't be c, because fire does not cause seeds to fly in. I would say B
