Cells make up the soft portions of tissues in living organisms

Cells are the basic functional units of living organisms

Cells join together to form multicellular organisms

Cells are responsible for coordinating activities in multicellular organisms

Blood vessels in the heart dilate to increase blood pressure

Blood vessels in the organs contract to increase blood oxygen

Blood vessels in the lungs contract to decrease blood volume

Blood vessels in the muscles dilate to increase blood flow

vacuole

plasma membrane

nucleus

Golgi complex

The antibiotics tend to become weaker over time as they accumulate mutations

Any bacteria with mutations protecting them from the antibiotics were more likely to live and pass on the mutations to future generations of bacteria

Human immune systems have adapted to the presence of bacteria, causing antibiotics to be less effective

Those bacteria that have once come in contact with antibiotics learn to avoid them and are difficult to kill

Cells were found that used something other than DNA as hereditary material

An organism was found with tissues made of something other than cells

A cell was found that could continue to divide and reproduce indefinitely

An animal cell was found that could harness solar energy as plant cells do

an increase in vein length

an increase in blood viscosity

a decrease in heart rate

an increase in blood pressure

New cells appear by spontaneous generation

Cells form from non-living materials, in a manner similar to how crystals are formed

Cells come from preexisting cells through cell division

A membrane forms around DNA that is released from a parent cell, and the DNA contains the information needed to produce organelles
