Why is the concentration of oxygen greater outside the cell?

because the environment has autotrophs to produce oxygen

Which is TRUE about the concentration of oxygen and carbon dioxide when in comes to cells?

oxygen (out) and carbon dioxide (inside) are both high

What is common in mammals, fishes and earthworms?

Gas exchange occurs along the capillaries

by constantly having smaller structures

Why is the avian respiration considered as the most efficient in the animal kingdom?

because the oxygen-rich air is attained

by having one cell, thin walled and flattened cells

Which among the following best describes the process of diffusion?

Particles move from higher to lower concentration.

What's the role of air sacs in the avian respiratory system?

it acts as bellows to store extra air

Which mechanism of fish, satisfies the criterion "high concentration gradient"?

Answers

1
Why is the concentration of oxygen greater outside the cell?
because it needs oxygen to perform respiration
because plankton produced more oxygen compared to trees
because the environment has autotrophs to produce oxygen
because the cell has greater oxygen inside
2
Why is there a need for humans to have millions of air sacs (alveoli)?
to maintain a concentration gradient
to maintain a moist surface area
to have a small distance travelled
to increase the surface area
3
Which of the following does NOT belong to the group?
Birds
Frogs
Insects
Mammals
4
Which is TRUE about the concentration of oxygen and carbon dioxide when in comes to cells?
oxygen (out) and carbon dioxide (inside) are both high
Oxygen (out) and carbon dioxide (inside) are both low
oxygen (out) and carbon dioxide (inside) are both moderate
Oxygen (out) is greater compared to carbon Dioxide (inside)
5
What is common in mammals, fishes and earthworms?
Gas exchange occurs along the gills
Gas exchange occurs along the skin
Gas exchange occurs along the capillaries
Gas exchange occurs along the lungs
6
Which of the following is TRUE about tracheal system?
have thick walled capillaries
have blood vessel to deliver oxygen
have large surface area
have small surface area
7
How do fishes meet the criterion, large surface area?
by developing gills in other animals
by constantly having smaller structures
by living under water
by developing an operculum
8
Why is the avian respiration considered as the most efficient in the animal kingdom?
because the "old air" mixes with the "fresh air"
because the oxygen-rich air is attained
because it performs a counter current exchange flow
because it has air capillaries and small capillaries
9
How do capillaries of different organism meet "small distance travelled"?
by having wet lining of capillaries
by having one cell thick membrane and flat walls of alveoli
by having one cell, thin walled and flattened cells
by having a small but thick membrane
10
Why would our cells need oxygen?
All are correct
Because oxygen is used to process energy resources
Because oxygen is used to remove wastes
Because oxygen is used to process energy
11
Which does NOT belong to the group?
Gills
Skin
Air Sacs (Aves)
Lungs
12
Which among the following best describes the process of diffusion?
Alveolus is only one cell thick, so diffusion is great.
The semi membrane allows particles to pass through.
Particles move from higher to lower concentration.
Oxygen need a moist membrane for it to be diffused.
13
What's the role of air sacs in the avian respiratory system?
it sucks oxygen from the air
it acts as bellows to store extra air
it acts like alveoli of the human respiratory system
it increases the surface area of the organism
14
Which mechanism of fish, satisfies the criterion "high concentration gradient"?
Water flows into the mouth, gill and out of the operculum
The water and blood flow in opposite direction
The blood and air capillaries flow in opposite direction
The concentration of oxygen is greater in water than gills
15
How do insects prevent desiccation?
by having an endoskeleton
by having spiracles and keeping them open
by working in tandem with the circulatory system
by having hairs around the spiracles
