Question

can you answer these questions

The lava released by a volcanic eruption separates two populations of a species of monkey. What does this represent?
biological isolation
geographical isolation
temporal isolation
anatomical isolation

Which of the following is an example of adaptive radiation?
One population of squirrels becomes two separate species over a long time.
One population of lizards forms 15 separate species over a short time.
One species of birds becomes better suited to its environment over time.
One species of fish forms when two species of fish begin to breed with each other.

Veronica got a cut on her arm, and it started bleeding. Her circulatory system started working hard to prevent blood loss and protect against infection.

Which two components of the blood were functioning at a higher level than normal?

platelets and plasma

plasma and red blood cells

white blood cells and platelets

red blood cells and white blood cells

Consider this microscopic image of bacteria.

A microscopic image of bacteria is shown. The bacteria is made up of 2 connected spherical shapes.
Which bacterial form is shown in the image?
bacillus
nucleoid
spirillum
coccus

Sophie says dolphins and sharks look very similar, so they must be related. Jake disagrees, saying DNA evidence has shown that dolphins and other aquatic mammals are actually more closely related to the ancestors of modern hippos. Who is correct using the modern system of classification?
Sophie is correct because dolphins look more like sharks than like hippos.
Jake is correct because classification is based on evolutionary relationships.
Both are correct because traditional and modern classifications can overlap.
Neither is correct because neither is taking into account both the traditional and modern systems

Answer 1

Here are the answers with brief explanations:

1) The lava separated two populations of a species of monkey. What does this represent?
- Answer: geographical isolation
(A physical barrier separates populations.)

2) Which is an example of adaptive radiation?
- Answer: One population of lizards forms 15 separate species over a short time.
(Many species arising quickly from one ancestor is adaptive radiation.)

3) Veronica got a cut; which two blood components increased activity to prevent blood loss and protect against infection?
- Answer: white blood cells and platelets
(Platelets form clots to stop bleeding; white blood cells fight infection.)

4) Microscopic image: two connected spherical bacteria. Which form is shown?
- Answer: coccus
(Spherical bacteria are cocci; two joined would be diplococci.)

5) Who is correct about dolphins and sharks?
- Answer: Jake is correct because classification is based on evolutionary relationships.
(Dolphins are mammals closely related to terrestrial mammals like hippos; sharks are fish.)
