<span>Pets might have fleas and other diseases that could be transferred to the food either by the pet directly coming into contact with the food or by way of employees after they come in contact with the pet. This is especially dangerous if the food establishment does not have very strict sanitation rules.</span>
Answer:
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Explanation:
The human brain consumes up to 20% of the energy used the entire human body which is any other single organ. the brain represents inly 2%of the body wheight yet it recieves 15% of the cardiac output and 20% of the total body oxygen consumption.
The vector, which is often a small, circular piece of dna that can exist outside the bacterial chromosome, is known as a plasmid.
Bacteria and certain other microscopic species contain plasmids, which are tiny circular DNA molecules. Physically distinct from chromosomal DNA, plasmids multiply on their own. They normally contain only a few genes, including some linked to antibiotic resistance, and they can spread from one cell to another.
Recombinant DNA techniques are used by scientists to splice the genes they want to research into a plasmid. The inserted gene is duplicated along with the plasmid when it duplicates itself. Molecular cloning, the process of creating DNA molecules and introducing them into a host cell, uses plasmid vectors as the means of delivering recombinant DNA into the host cell.

Answer:
Analogous structures are structures which serve similar function in different organisms and evolved independently in two living organisms while homologous structures are the structures which are similar in related orgnanism due to inheritance.
The wings of Pterodactyl, bats and birds are conisdered as analogous structure. <u>they are similar in structure and same in function and evolved independently in the two groups of animals.</u>
Bones in forelimbs of pterodactyl, bats and birds are considered homologous structures as <u>they inherited the pattern from a common ancestor and have different functions.</u>
