answer for this question is A
Answer:
Making an area unavailable to plants and animals
Explanation:
Answer:
Transosteal
Explanation:
One of the ways to get a missing or broken tooth fixed is through dental implants. It can also be used to fix loose teeth. For this to occur, a tooth root is needed to hold in place the dental prosthesis. Dental implants involve surgically fixing of metal frames (surgical component) into the jawbone beneath the gum to serve as the tooth root. This surgical implant, which now serves as a tooth root, enables the dentist to fix a replacement tooth.
<em>Transosteal implant</em> is a type of dental implant in which the surgical component is a U-shaped metal frame or pins that is inserted into the lower jaw followed by the replacement tooth on top during tooth replacement.
Answer: A. The genes encode resistance to antibiotics.
D. The genes are carried on plasmids
F. The "clock"genes are highly mobile between species.
Explanation:
Molecular clock is a tool that is used to calculate the time of the evolutionary events. These are the gene sequences that are used to determine the evolutionary distance between the new and primitive organisms developed on earth. It also measures the random changes just like mutation. Thus the molecular clock is also called as the gene clock or evolutionary clock.
The accuracy of the molecular clock can be increased by the genes that encode for a resistance against the antibiotics, the genes that are carried on the plasmids and the clock genes which are highly mobile among the species.
