Atoms may have different numbers of neutrons. Atoms are the smallest fraction of an element that can exist, and still show the properties of the element. They consists of electrons (negatively charged), protons (positively charged), and neutrons (no charge). The number of electrons is equivalent to the number of protons normally however an atom may loose or pick up electrons and have a positive charge or negative charge. The number of neutrons in the nucleus may vary within a given element to give varieties of atoms we call isotopes.
The situation is an exponential growth wherein an example is on population when as the population gets larger, it grows more quickly.
Difference between a plant and an animal cell:
- Plants have cell walls, animals don't
- Plants have a large central vacuole, while animals have small scattered vacuole
- Plants cells are rigid and strong, referred to as <u><em>Turgid </em></u> in science, and have a definite shape
- Animal cells dont have a definite shape
Hope this helps
An endangered species is a type of species in which this type of organism has decreasing numbers and are dangerously close to going extinct. Invasive species are species in which an organism invades an environment where it is not native to, and take over the ecosystem. Local species are species in which the organism is native to that environment and plays a key role in that ecosystem. A keystone species is a species in which the organism is a key part of that ecosystem to thrive; without it, the ecosystem would collapse
