Which of the following makes treating and curing the common cold virus in humans difficult?(1 point)

Question

Responses

It is a spherical-shaped virus with many protein receptors.
It is a spherical-shaped virus with many protein receptors.

It attacks white blood cells that fight off foreign bodies.
It attacks white blood cells that fight off foreign bodies.

It is caused by a special type of virus called a retrovirus.
It is caused by a special type of virus called a retrovirus.

It possesses a viral genome that mutates very quickly

Answer 1

The correct response that makes treating and curing the common cold virus in humans difficult is:

It possesses a viral genome that mutates very quickly.

The common cold is primarily caused by rhinoviruses, which are known for their rapid mutation rates. This high mutation rate allows the virus to evade the immune system and complicates the development of effective treatments and vaccines.

Answer 2

If a person has high blood pressure, the first step of doctor might take is to prescribe a basic blood pressure medication that helps the kidneys remove sodium and water from the body. How does this medicine work to fix the issue?(1 point)
Responses

It improves blood quality, reducing blood pressure.
It improves blood quality, reducing blood pressure.

It removes blockages, reducing blood pressure.
It removes blockages, reducing blood pressure.

It decreases the likelihood of clots forming, reducing blood pressure.
It decreases the likelihood of clots forming, reducing blood pressure.

It reduces blood volume, reducing blood pressure.

Answer 3

The correct response is:

It reduces blood volume, reducing blood pressure.

The medication described is likely a diuretic, which helps the kidneys remove excess sodium and water from the body. This reduction in fluid leads to a decrease in blood volume, which in turn helps lower blood pressure.

Answer 4

Which of the following would be considered an advantage of using a scientific model?(1 point)
Responses

Scientific models can differ in the level of details shown
Scientific models can differ in the level of details shown

Scientific models may not show the complete picture
Scientific models may not show the complete picture

Scientists can use models for research when real objects are too large to obtain
Scientists can use models for research when real objects are too large to obtain

Scientific models may be over simplified

Answer 5

The correct response highlighting an advantage of using a scientific model is:

Scientists can use models for research when real objects are too large to obtain.

This statement conveys that models are beneficial because they allow scientists to study and understand large or complex systems that would be impractical or impossible to analyze directly.

Answer 6

Which animal is often used to model human body systems?(1 point)
Responses

pig
pig

rabbit
rabbit

cow
cow

sheep

Answer 7

The correct response is:

pig.

Pigs are often used in research as models for human body systems due to their anatomical and physiological similarities to humans, including organ size and function, which makes them valuable in various medical studies.

Answer 8

Which important event occurs in the second trimester of human development?(1 point)
Responses

The developing human starts responding to sounds.
The developing human starts responding to sounds.

The developing human can begin to move its arms and legs.
The developing human can begin to move its arms and legs.

The heartbeat of the developing human strengthens and can be heard of via stethoscope.
The heartbeat of the developing human strengthens and can be heard of via stethoscope.

The face of the developing human starts to form.

Answer 9

The correct response for an important event that occurs in the second trimester of human development is:

The developing human can begin to move its arms and legs.

During the second trimester, fetal movements, often referred to as "quickening," can typically be felt by the mother, as the muscles and nervous system are developing sufficiently to allow for movement.
