Most viruses reproduce through a process called lytic infection. During lytic infection, a virus enters the host cell, makes a copy of itself, and causes the cell to burst, or lyse.
Hope this helps :)
Compare and contrast two mechanisms for transcriptional termination in bacteria.
(rho)p-dependent termination: requires rut (rho utilization site), rho protein binds, moves towards 3' end, DNA encodes GC rich for stem loop, RNApoly pauses, rho protein catches up and separates RNA-DNA hybrid
(rho)p-independent termination: Uracil-rich sequence causes RNApoly to pause, stabilized by NusA near open complex RNA exit, UA bonds to weak to hold, DNA-RNA hybrid dissociates AKA intrinsic termination
hope this help

Answer:
Explanation: The body mass is a weight of the person. The total surface area of the air sacs means that in an organism who is having air sacs, spaces are present in them In these air sacs there is a presence of air which is constant.
Explanation:
The relationships between the ratios of Hemoglobin total surface area of such conditions result from the available amount of air sacs that permits.
Birds of 21 species with body mass ranging from 8 to 170 g, in eight species of antiracial.
Air sacs are present as small sacs off the bigger respiration tubes (tracheae) of insects, as prolongation of the lungs in birds, and as final organs in the lungs of certain other vertebrates.
They give to increase respiratory efficiency by giving a huge superficial area for gas transportation.
