Invasive species reduce biodiversity levels, create a nuisance, cause economic loss, and disrupt ecosystem equilibrium.
<h3>Effects of invasive species</h3>
- Invasive species tend to drive away or kill native species.
- Invasive species reduce the overall biodiversity of plants or animals in the ecosystem.
- They cause economic loss through the loss of important native species.
- They create nuisance in the environment and may be costly to get rid of.
- They affect ecosystem equilibrium by causing species change.
- They are usually difficult to manage.

Answer:
The density of a population can be regulated by various factors, including biotic and abiotic factors and population size. Density-dependent regulation can be affected by factors that affect birth and death rates such as competition and predation.
Answer:
Fossil B is the same age as the index fossil.
Explanation:
TOO LATE BUSTER
... termed "hypotonic," meaning less solids (or more diluted) than inside the cell. For fluid movement in/out of cells, water will diffuse (via osmosis) from the hypotonic solution to the hypertonic one, assuming a permeable barrier (i.e. cell membrane) allows it. With this case, water will flow into the cell from outside.
Stem cells are unique in the fact that they can replicate any type of cell and their function. They help in cases of disease and injury because the replication properties can also be applied to white blood cells; these are cells that destroy pathogens.
