Water

Question 1

what percent of milk is water?

Answer 1

85-87%

Question 2

What are some things that result in death related to water

Answer 2

High TDS (total dissolved solids) –> Sulfates and nitrates.

Question 3

What increases TDS?

Answer 3

Drought, extreme heat

Question 4

What is a universal solvent?

Answer 4

Water

Question 5

What results in the complete oxidation of glucose?

Answer 5

Glycolysis and TCA cycle

Question 6

When a peptide bond is formed, what is the byproduct?

Answer 6

Water

Question 7

What are ways to dissipate heat?

Answer 7

Water play a critical role

Heat loss: Sweat/evaporation, radiation, conduction, covection. (not asked)

Sweating, hyperventillation. Find shade, drink lots of water. Slow metabolism.

Question 8

What is specific heat capacity?

Answer 8

The amount of E it takes to heat 1 cal of water by 1 degree.

Question 9

What is the role of thermal conductivity?

Answer 9

Allows water to transport heat efficiently from deep body tissues to surface.

Question 10

What is the importance of the high latent heat of vaporization?

Answer 10

58 cal of heat to convert 1g of water from liquid to vapour.

Panting, and sweating are efficient ways to lose heat.

Question 11

An increase in feed intake should result in increase/decrease in water intake?

Answer 11

An increase in feed intake should result in an increase in water intake?

Question 12

Which is more adapted for hotter climate Bas Indicus & Bos Taurus?

Answer 12

Bos Indicus- Brahma. Hotter climate, more adapted to heat. More sweat glands.

Question 13

Sympoms of water deprivation?

Answer 13

Reduced feed intake, increase heart rate, increased body temp, increased respiration, lack of muscle coordination. Sunked eyes, shrivelled skin. death.

Question 14

water quality

Answer 14

Question 15

features of good quality water

Answer 15

• Clear and colorless
• Low total solids
• No disease organisms or pesticides
• No undesirable flavour or odor

Question 16

Which physical property of water allows large changes in heat production due to chemical reactions taking place in the body’s cells with little alteration in body temperature?

a) high thermal conductivity
b) water is a universal solvent
c) high latent heat of vaporization
d) high specific heat capacity

Answer 16

d) high specific heat capacity

Question 17

Which physical property of water allows the dissipation of large amount of heat from the body’s surface, thus playing a major role in regulation of body temp?

a) water is a universal solvent
b) High latent heat of vaporization
c) High thermal heat of vaporization
d) High specific heat capacity

Answer 17

Which physical property of water allows the dissipation of large amount of heat from the body’s surface, thus playing a major role in regulation of body temp?

C) High thermal conductivity

Question 18

The order of importance, list 3 sources of water for animals.

Answer 18

Free water

Water from feed

Metabolic water

Question 19

LIST 2 dietary factors that will affect water intake in animals. No additional discussion

Answer 19

Increase in DM intake. Increase in dietary protein.

Question 20

In ONE sentence, what happens to feed intake in animals when water intake is restricted and why does it happen?

Answer 20

Feed intake will decrease when water intake decreases because water is critical in several roles of digestion and as a universal solvent for absorption of nutrients.

Question 21

in ONE sentence, what happens to water intake in animals with high ambient temperatures and why does it happen?

Answer 21

Water intake increases with high ambient temperature becasue there is more evaporative loss from panting and sweating so that animal will try to compensate by drinking more water.
