Read the following passage from the Biology Department at University of California, Berkeley. Northern elephant seals have reduc

ed genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely. Which of the following best describes how the population has evolved? a. The population has not evolved because there was no change in allele frequencies. b. The population has not evolved because it has grown. c. The population has evolved because it has grown. d. The population has evolved because there was a change in allele frequencies.

Answer:

The population has evolved because there was a change in allele frequencies.

Explanation:

The evolution may be defined as the process of the change of the species characteristics with the passage of the time. The natural selection, mutation and the genetic drift might cause the evolution.

The population might have evolved as the allele frequencies has changed from the generation to the generation. Although the variation among the population is quite less but the variation is still enough for the evolution of the elephant seals.

Thus, the correct answer is option (D).

Answer:

B

Explanation:

B leaves tiny stinging barbs, which since it's on leaves, prey wouldn't expect it because it would blend in with the environment. C has thorns that would pierce the skin, I'm guessing that it would be visible to prey.

Seaweed belongs to which of Earth’s spheres?<br> atmosphere
LUCKY_DIMON [66]

Answer:

Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

So I would say seaweed belongs in the hydrosphere.

I hope it helps.

Answer:

FRONTAL LOBE

Explanation:

The frontal lobe can be located at the anterior part of the brain, extending back to a fissure known as the central sulcus. The frontal lobe functions and helps in coordination of reasoning, motor control, emotion, and language. It contains the motor cortex, which is involved in planning and coordinating movement; the prefrontal cortex, which is responsible for higher-level cognitive functioning; and Broca’s area, which is essential for language production.

Let say for example Kyle is my friend who was a victim of an accident.

Before the accident, he was industrious and well liked BUT after the accident, he is profane, impetuous, and incapable of working toward a goal.

Such changes in personality would be consistent with loss of impulse control which is a significant frontal lobe function. With connections between the planning functions of the frontal lobe and the emotional processes of the limbic system severed, Kyle had difficulty controlling his emotional impulses, attitudes and abiiity of working towards his goals.
