Answer:
True. This is the case where an invasive species has reduced the genetic diversity of indigenous species.
Explanation:
- An invasive species is an exotic, foreign species that takes over a specific habitat or ecosystem and destabilizes it.
- Invasive species disrupt the food chains of an ecosystem which may lead to increase in populations of some species while reducing others.
- Invasive species compete with indigenous species for food, shelter and mates. As the indigenous species cannot reproduce properly, a reduction in their genetic diversity is the direct result.
Answer:
Explanation:
Deoxyribonucleic acid is said to contain instruction for species characteristics because it carries the information that characterize an individual.
DNA are made up of Nitrogenous bases that are unique codes specify by an individual and no two person has the same the DNA.
Genes are genetic information or instruction that specify an individual. it is located in the chromosome in the nucleus. DNA contains gene which helps to make molecules called proteins. It is the basis of all inheritance and the expression of the gene is what produces the phenotype that is visible.
Answer:
Adverse effect on the animals.
Explanation:
If the rabbit population suddenly shrank due to disease, it will adversely affected the population of eagle, fox and coyote because these animals depend on them through feeding. Eagle, fox and coyote feed on the rabbit so if the population of rabbit decreases, then there will be scarcity of food for these animals and as a result decrease occur in their populations so we can say that adverse effect occurs on the population of eagle, fox and coyote.
Answer:Density is a characteristic property of a substance. ... The mass of atoms, their size, and how they are arranged determine the density of a substance. Density equals the mass of the substance divided by its volume; D = m/v. Objects with the same volume but different mass have different densities.
