Answer:
DNA and proteins
Explanation:
By comparing these specific molecules in two different species, scientists can determine how closely related the species are.
Answer:
D. The native snail species will compete for resources with the invasive species and destabilize the ecosystem
Explanation:
In Ecology, an invasive species refers to a species of organism that is foreign i.e. non-native to a particular habitat or environment. They are characterized by the ability to proliferate in growth and compete for space and nutrients with the native species in the habitat they are introduced to.
In this case, the giant african land snail, which is an invasive species, if introduced into a stable ecosystem will compete for resources with the native species of that ecosystem leading to the destabilization of the ecosystem.
Homeotic genes regulate the development of structures. Logically, then, the mutation of this gene must result in improper structure development, such as structures in abnormal places. The answer is C.
While insulin suppresses gluconeogenesis, glucagon increases glycogen.
