Answer:

I would predict that the the following generation will have a large amount of pups that are eaten by the sharks.

This question seems like its asking about natural selection.

"Natural selection is the process when organisms better adapted to their environment tend to survive and produce more offspring"

Explanation:

If the marine biologist did not give the pups medicine in the first generation, the pups that were less fit or not adaptive to the enviroment to naturally survive the infections would have died. This would have prevented these pups from passing on their genes.

The next generation would consists of pups that are more immune to the sickness or more fit for their enviroment and might experiece less pups to die.

Abnormally slow depolarization of the ventricles would most change the shape of the ________ in an ECG tracing. Group of answer

NeTakaya

Abnormally slow depolarization of the ventricles would most change the shape of the QRS complex in an ECG tracing.

The conduction system in the ventricles depolarizes, and this depolarization spreads along the walls of the ventricles to produce the QRS complex.
It represents electrical activity that occurs before the ventricles contract (ventricular systole). The QRS complex appears immediately after the onset of ventricular systole.
An aberrant depolarization of the ventricles results in the formation of an abnormal QRS complex.
The SA node, an ectopic pacemaker in the atria, AV junction, bundle branches, Purkinje network, or the ventricular myocardium are all possible pacemaker sites in these aberrant QRS complexes.
An aberrant QRS complex might have any shape, from normal to wide and odd to slurred and notched.

Why did Darwin see savage competition as a creative process?

tekilochka [14]

Answer: According to Darwin theory of evolution the struggle for existence is considered as major part for competition among living things.

Explanation:

Coexisting species that belong to the same genera compete for same kind of resources for their survival. Some phenotypic variations gives an survival advantage over others. The superior ones dominate the inferior ones and compete for resources. The one who receives the resources like mates, food, shelter, and others the chances of survival also increases considerably.
