Heterozygous is the answer.
Answer:
Arthropods invaded land about 100 million years before vertebrates. This fact most clearly implies that a. arthropods have had more time to co-evolve with land plants than have vertebrates
Explanation:
Arthropods are invertebrates animals. Its evolutionary ancestry dates back to the Cambrian period and they have had more time to co-evolve with land plants than have vertebrates. The vertebrates share a common ancestor. Scientists believe that the last common ancestor of all arthropods is a modular organism with each module covered by its own sclerite.
Ionic bonding is a type of chemical bonding that involves the electrostatic attraction between oppositely charged ions, or between two atoms with sharply different electronegativities, and is the primary interaction occurring in ionic compounds
Hope this helped :)
Haven't done living environment in a few years, but the assumption should be "2) female offspring would be unable to bite humans, since they can't fly" and the method would be 3) biotechnology.
The answer to "assumption questions" can usually be figured out by just reading the information given. Since its talking about FEMALE mosquitoes BITING HUMANS and spreading diseases, the second answer is most relevant.
The second question requires you to understand the definitions of each answer choice (or atleast the correct one). The most relevant answers would be 2 and 3, as those refer to humans changing the characteristics of a species. However, again, referring to the information given, we know that the research being conducted is with the DNA of male mosquitoes being altered. This is not an example of selective breeding, but rather of biotechnology.
The answer is the salivary gland.
Saliva is secreted through the surface of the tongue.<span />
