Lecture 18- Size and scaling

Question 1

Allometry

Answer 1

Differential growth of body parts that results in a change of shape or proportion with size.
Allo = other than
Metron = measure

Question 2

Isometry

Answer 2

A transformation that does not change the size or shape of a figure.
Iso= same
same as metric

Question 3

LSD and elephants

Answer 3

People gave too much LSD to elephant as they scaled up the amount of LSD for a cat
Cat’s and elephants have different metabolic rates.
It didn’t end well

Question 4

Uses of allometry

Answer 4

Used to estimate the food requirements of the great cormorant

Question 5

Pressure and gravity

Answer 5

Pressure only depends on the height of fluid in a column.

Volume has not effect on pressure

Question 6

Pressure overcoming gravity example

Answer 6

Elephants heart is further away from it’s brain than a mice heart.
Therefore in order to that blood to reach the elephants brain must be more pressure.

Question 7

Blood pressure pattern in animals

Answer 7

Blood pressure increases as distance between heart and it’s head

Question 8

Does size matter?

Answer 8

Mass influences a great many physiological, ecological and life-history variables
