Increase in intrathoracic pressure causing air to rush out

Decrease in lung volume causing inhalation

Decrease in intrathoracic pressure causing air to rush in

Passive relaxation of the diaphragm causing exhalation

They must pass through capillaries and lack a nucleus

They are single-celled organisms

They must produce antibodies

They contain multiple nuclei and mitochondria

Take blood pressure instead

Use a stethoscope to listen to the lungs

Use a digital heart rate monitor for comparison

Count the number of breaths per minute

Use of dyes and staining in microscopy

Invention of ultracentrifugation and cell fractionation techniques

Discovery of antibiotics

Observation of mitosis under light microscopes

The organism was likely a predator

It had a diet high in protein

It was adapted to nocturnal hunting

It was likely herbivorous

To pump water into lysosomes using ATP

To form vesicles during exocytosis

To allow rapid diffusion of water molecules through the membrane

To hydrolyze solutes in the extracellular space

Decreased overall oxygen requirement

Increased distance between surface and internal cells

Increased permeability of the outer skin

Greater total surface area due to more cells

Floating in the middle of the membrane’s hydrophobic core

Spanning across both sides of the membrane

Loosely attached to one surface of the membrane, often via other proteins

Synthesizing DNA on the outer surface of the nucleus

Only lignified walls and pits

Only hollow, dead cells and pits

All three features contribute

Pits and lignin reduce transpiration

It reacts with a base to dissolve the polymer

It supplies -H and -OH groups to opposite ends of the broken bond

It converts the polymer into ATP

It draws out carbon atoms from the chain
