Answer: option A - threat, after habitat loss, to native species of plants and animals and to the maintenance of biologically diverse ecosystems
Explanation:
Invasive species refers to organisms that appears at a particular habitat that has just undergone an environmental unfavorable condition.
These INVASIVE SPECIES poses THREAT to the native organisms, because they usually possess:
better resistance to disease,
higher reproductive rate, etc.
So, even when native organisms migrate or dies, Invasive species REMAINS. As a result, they threaten the maintenance of a biologically diverse ecosystem
Answer:
DNA, found within the nucleus, must be replicated in order to ensure that each new cell receives the correct number of chromosomes.
A reproductive strategy presents an approach of a type of an organism to reproduction and of taking care of it's offspring.
Generaly speaking, there are two main reproductive strategies, K and R reproductive strategies.
The organisms that apply the R strategy produce a great number of small, independent offspring and when the offspring is born or hatched it's left to
try to survive on its own. This strategy is used by bacteria, many invertebrates, and reptiles.
On the other hand, the K strategy organisms produce a small number of offspring that they care of for a significant amount of time after they are born. This strategy is used mostly by mammals and birds.
