heat stress
oxygen deprivation
salt stress
water deficit
Plants have hormones
True
False
This system is made up of hormones and glands.
The Integumentary System
The Endocrine System
The Nervous System
The Digestive System
A plants xylem is responsible for transporting
Sugar
Nutrients
Blood
Water
A plant's phloem is responsible for transporting
Light
Nutrients/Glucose
Blood
Water
A plant's stomata is an opening in the plant's leaves that can open and close to let in ________ and let out _________
Carbon Dioxide, Oxygen
Water, Oxygen
Oxygen, Carbon Dioxide
Nutrients, Water
What is the process that causes plants to lose water through their stomata?
Persperation
Phloem
Transpiration
Transportation
The Xylem moves water
One-way or One Direction
Two-ways or Two Directions
The Xylem does not move water.
ADH is created in the:
Hypothalamus
Posterior Pituitary Gland
Brain
Kidney
ADH is released from the pituitary gland into the:
Circulatory system
Endocrine system
Nervous system
All of the above
When ADH is secreted, urine will:
Be more dilute
Be more concentrated
Have a larger volume
All of the above
When you drink a larger volume of water than is required by your body tissues:
ADH secretion will be increased
ADH secretion will be inhibited
ADH secretion will not be affected
None of the above
Cells that detect high blood concentration are called:
Chemoreceptors
Osmoreceptors
Thermoreceptors
Nociceptors
Changes in blood volume and concentration are detected in the brain cells in the:
Posterior Pituitary Gland
Anterior Pituitary Gland
Thalamus
Hypothalamus
Anti-diuretic hormone (ADH) is released by which gland of the endocrine system
Thyroid
Pituitary
Ovaries
Adrenal
If you are dehydrated (low water potential in the blood), the body must conserve water. To do so, the brain triggers the pituitary gland to ...
release MORE ADH, making the collecting duct MORE permeable
release LESS ADH, making the collecting duct LESS permeable
release MORE ADH, making the collecting duct LESS permeable
release LESS ADH, making the collecting duct MORE permeable
If you are over-hydrated (high water potential in the blood), the body must excrete excess water. To do so, the brain triggers the pituitary gland to ...
release MORE ADH, making the collecting duct MORE permeable
release LESS ADH, making the collecting duct LESS permeable
release MORE ADH, making the collecting duct LESS permeable
release LESS ADH, making the collecting duct MORE permeable
what is osmoregulation?
Control of water and salt in the body
Control of blood pressure in the body
Control of blood glucose in the body
ADH causes specific protein channels to move into the membranes of certain cells in the nephron so that more water can be absorbed by osmosis. What are these called?
aquaporins
active transport
tight junctions
desmosomes
What causes blood glucose levels to rise?
eating
vigorous exercise
sleeping
going to the toilet
What type of foods are broken down into glucose in the small intestine?
carbohydrates
proteins
fats
What do cells need glucose for?
photosynthesis
respiration
protein synthesis
combustion
Which of the following is a hormone used to control glucose concentrations in the blood?
insulin
glycogen
pancreas
adrenaline
Which organ produces insulin?
(a)
Insulin causes which organ to remove glucose from the blood?
liver
pancreas
brain
kidneys
What do we call the process that controls the amount of blood glucose levels?
glucoregulation
sugaregulation
insulination
hormonal control
Excess glucose in the bloodstream is converted to which other substance when stored in the liver and muscle cells?
glygogen
glucagon
glycerin
glycerol
What happens to the amount of insulin released if the blood glucose levels get low?
lots more is produced
nothing - low blood glucose has no effect on insulin levels
less / no insulin is produced
What name do we use to describe the maintaining of constant conditions, such as blood glucose levels, body temperature and water levels, inside the body?
hormonal control
homeostasis
nervous system
endocrinasis
According to the feedback loop, what does high blood sugar promote?
Insulin Release
Glucagon Release
Insulin Uptake
Glycogen Uptake
What is the difference between what will happen if their is too much Glucose or too little Glucose? SELECT ALL THAT APPLY
With too much Glucose, Insulin is released. With too little Glucose, Glucagon is released.
With too much Glucose, the pancreas produces insulin. With too little Glucose, the pancreas produces glucagon.
With too much Glucose, Glucagon is released. With too little Glucose, Insulin is released.
There is no difference.
It is important that our body temperature stays constant as at high temperature the enzymes
(a)
Where is the thermoregulatory centre loacted?
In the pituitary gland of the brain
In the cerebellum of the brain
In the hypothalamus of the brain
In the cortex of the brain
Which arteriole is dilated?
1
2
3
Which arteriole is constricted?
1
2
3

What changes occur to cool the body down
vasoconstriction, increase sweating and hairs lie flat
vasodilation, increase sweating and hair erector muscle relaxes and hairs lie flat
Vasodilation, reduced sweating, hair erector muscle relax and hair stand up.
Vasoconstriction, increase sweating and hair erector muscle relaxes and hairs lie flat
What changes occur to increase body temperature
Vasoconstriction, hair erector muscle relaxes and hair pulled upright, no sweating and shivering
Vasodilation, hair erector muscle contract and hair pulled upright, no sweating and shivering
Vasoconstriction, hair erector muscle contract and hair pulled upright, no sweating and shivering
Vasodilation, hair erector muscle contract and hair pulled upright, increased sweating and shivering
