Questão 1
Questão
Insulin [blank_start]reduces[blank_end] blood sugar levels by converting [blank_start]glucose[blank_end] into [blank_start]glycogen[blank_end] in the [blank_start]liver[blank_end]
Responda
-
reduces
-
increases
-
glucose
-
glycogen
-
liver
-
pancreas
Questão 2
Questão
When blood sugar levels decrease [blank_start]glucagon[blank_end] is secreated from the [blank_start]pancreas[blank_end] which breaks down [blank_start]glycogen[blank_end] in the [blank_start]liver[blank_end] to [blank_start]glucose[blank_end]
Responda
-
glucagon
-
glycogen
-
pancreas
-
liver
-
glucose
Questão 3
Questão
The nervous system uses [blank_start]electrical impulses[blank_end] to enable you to react to your surroundings and [blank_start]control[blank_end] what you do.
Cells called [blank_start]receptors[blank_end] detect changes in the environment known as stimui.
Impulses from receptors pass along [blank_start]sensory[blank_end] neurones to the brain. Impulses are sent from the [blank_start]brain[blank_end] to the [blank_start]effector organs[blank_end] along [blank_start]motor[blank_end] neurones.
Responda
-
electrical impulses
-
hormonal impulses
-
control
-
receptors
-
effectors
-
sensory
-
relay
-
brain
-
effector organs
-
motor
Questão 4
Questão
Nerve impulses pass across a synapse gap by the [blank_start]diffusion[blank_end] of [blank_start]neurotransmitters[blank_end]
Responda
-
diffusion
-
neurotransmitters

a stimulus
-
light
-

Questão 7
Questão
Positive phototropism is...
Responda

Responda
-
negative geotropism
-
positive geotropism
-
negative phototropism
-
positive phototropism
Questão 9
Questão
What are the chemicals that cause changes in plants
Responda
-
hormones
-
impulses
-
auxins
-
gibberellins
Questão 10
Questão
What do auxins do?
Questão 11
Questão
Carbohydrates in our food are broken down to [blank_start]glucose[blank_end], which is absorbed into the [blank_start]blood[blank_end]. As the concentration of glucose in the blood rises, the [blank_start]pancreas[blank_end] senses a change and releases a hormone called [blank_start]insulin[blank_end]. This hormone travels to the liver in the blood. The [blank_start]liver[blank_end] starts removing [blank_start]glucose[blank_end] from the blood and turning it into [blank_start]glycogen[blank_end]. This is stored in the [blank_start]liver[blank_end], when blood glucose levels get very low, the [blank_start]pancreas[blank_end] senses the change and produces another hormone called [blank_start]glucagon[blank_end]. This hormone also travels to the liver, where [blank_start]glycogen[blank_end] is turned back into [blank_start]glucose[blank_end] and released back into the blood. (This is an example of [blank_start]negative[blank_end] [blank_start]feedback[blank_end])
Responda

Questão 12
Questão
What can gibberellins do?
Responda
-
make plant shoots grow longer
-
control when seeds germinate
-
makes shoot cells grow longer
-
benefit to positive phototropism
Questão 13
Questão
How do auxins help a plant bend towards the light
Responda
-
auxins move to lit side of the shoot and glow
-
auxins move to shaded side of the shoot
-
auxins on shaded side of the shoot denature
-
auxins sense light and grow towards it
