Neutrons are the subatomic particles that are stored in the core of an atom with the protons. An atom is mostly empty space. At its center is a nucleus made up of particles made up of particles with a positive electric charge called protons and electrically neutral neutrons.
Isotopes is a word that gets thrown around in chemistry very often. Isotopes are different versions of an element or different versions of a certain kind of atom. Isotopes deal with atoms having different numbers of neutrons but the element will be the same but one may be heavier or lighter than another.
Answer:
B. helping the seeds to be scattered in new areas to grow.
Explanation:
- The scattering of seeds away from the parent plant is termed as seed dispersal and there are several mechanisms by which seeds can be dispersed, some of the means include gravity, wind, water, animals, etc.
- Seeds that have spiky structures such as hooks or claws are usually dispersed by animals.
- These spiky structures help the seeds to attach to the animal's fur or a feather and also to the bags or clothes of humans and thus, the seeds get scattered to new places along with the animals as they rub the seeds off their body or they fall on their own.
- Thus, <em>the spiky structure of seeds benefits the plant by as it helps in the dispersal of seeds and the plant can thus, grow in new areas.</em>
