Explanation:

Brachiation or arm swinging is a form of arboreal locomotion in which the animal swings from one branch to the other, using only their arms, this form of locomotion in the long evolutionary term is related to shorter legs as they are less heavy, and allow better swinging, and stable lumbar spines that counteract with the movement, for it not to get deformed with the constant swinging.

loris [4]

Answer;

The above statement is true

Explanation;

-Complement is a system of plasma proteins that can be activated directly by pathogens or indirectly by pathogen-bound antibody, leading to a cascade of reactions that occurs on the surface of pathogens and generates active components with various effector functions.

-C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system. C3b is potent in opsonization: tagging pathogens, immune complexes (antigen-antibody), and apoptotic cells for phagocytosis.

eimsori [14]

Answer:

Interrupted mating experiments can determine gene order on the Hfr bacterial chromosome.

Explanation:

Interrupted mating is a technique used in experiments involving microbiology. This experiment was created by geneticists François Jacob and Elie Wollman, in the late 1950s. This technique allows the mapping of the genes of the bacteria involved in the place where the conjugation was interrupted, within monitored and controlled time intervals. In this way, the technique allows showing the transfer mechanisms and the gene transfer itself.

In relation to the question above, we can say that the interrupted mating experiments can determine the order of the genes on the bacterial chromosome Hfr.
