Question 1

The process of regulating internal conditions so that they remain steady even when the physical environment does not match them is called ___________.

Accepted Answer

The answer of The process of regulating internal conditions so...

Question 2

Animals can gain, but not lose, heat by conduction.

Accepted Answer

Animals can both gain and lose heat by conduction. For example, if an animal lies on a cold surface, it will lose heat to that surface by conduction. Conversely, if an animal lies on a warm surface, it will gain heat from that surface by conduction.

Question 3

Secretion and ____________ take place in the U-shaped kidney tubule.

Accepted Answer

The answer of Secretion and ____________ take place in the...

Question 4

An animal that does not maintain a relatively constant core temperature is a(n) _________.

Accepted Answer

The answer of An animal that does not maintain a...

Question 5

A large glass of ice water and a small glass of ice water are sitting on a table in the same room. The small glass of water would reach room temperature before the large glass of water.

Accepted Answer

The larger volume of water in the large glass will take longer to reach room temperature due to its higher heat capacity.

Question 6

How might air conditioning reduce the number of deaths resulting from heat waves?

Accepted Answer

All of the choices listed are correct and show how air conditioning can reduce the number of deaths resulting from heat waves. By replacing warm air with cooler air, increasing the temperature difference between the body and the environment, and preventing dehydration, air conditioning can help people regulate their body temperature and avoid heat-related illnesses or death.

Question 7

Most marine animals and all land animals are ____________ because they maintain internal salt and water levels that are not the same as those of their surroundings.

Accepted Answer

The answer of Most marine animals and all land animals...

Question 8

________ feedback keeps the internal environment in a constant state within a range of external conditions.

Accepted Answer

The answer of ________ feedback keeps the internal environment in...

Question 9

An animal can lose heat by ___________ even when the environmental temperature is greater than its internal temperature.

Accepted Answer

The answer of An animal can lose heat by ___________...

Question 10

__________ tissue, the interface between an organism and its environment, regulates the amount of water, heat, and other substances that are exchanged with the external environment.

Accepted Answer

The answer of __________ tissue, the interface between an organism...

Question 11

Evaporation cools by radiation.

Accepted Answer

Evaporation cools through the process of latent heat absorption, not by radiation. When a liquid evaporates, it absorbs heat from its surroundings to change its state from liquid to gas, thereby cooling the surface it evaporates from.

Question 12

Shivering and goose bumps are ways of producing _____.

Accepted Answer

The answer of Shivering and goose bumps are ways of...

Question 13

During the day, camels allow their body temperature to rise to up to 40.5°C. At night, their temperature drops back to normal as a result of __________ when the air temperature drops below the camel's body temperature.

Accepted Answer

The answer of During the day, camels allow their body...

Question 14

Animals can gain or lose heat by conduction and radiation, but the process of ___________ only results in heat loss.

Accepted Answer

The answer of Animals can gain or lose heat by...

Question 15

A turtle lying on a warm rock on a sunny day is gaining heat from the sun by radiation and heat from the rock by _____________.

Accepted Answer

The answer of A turtle lying on a warm rock...

Question 16

In kidneys, the glomerulus is composed of a bed of __________.

Accepted Answer

The answer of In kidneys, the glomerulus is composed of...

Question 17

Ectotherms depend more on heat from their environment than on _________ heat from internal chemical reactions.

Accepted Answer

The answer of Ectotherms depend more on heat from their...

Question 18

Sweating results in heat loss by convection.

Accepted Answer

The answer of Sweating results in heat loss by convection....

Question 19

Frostbitten tissue, because water within cells freezes, expands, and ruptures plasma membranes.

Accepted Answer

When water within cells freezes, it expands and can rupture plasma membranes, leading to tissue damage and eventually frostbite.

Question 20

The basic functioning unit of the kidney is the _______.

Accepted Answer

The answer of The basic functioning unit of the kidney...
