11The Iris is the coloured part of the eye which helps control the pupils size and therefore the amount of light let into the eye.
- ARichtig
- BFalsch
12What applies to the pupil?
- AIt is a nerve
- BThe pupil is a muscle
- CThe pupil is coloured
- DIt controls how much light is let into the eye
- EIt is where light exits the eye

13What is the function of the cornea?
- AThe cornea is a protective and transparent layer at the forefront of the eye which reflects the light
- BThe cornea is a protective and transparent layer at the forefront of the eye which refracts the light upon entry.
- CThe cornea is a coloured layer at the forefront of the eye which refracts the light upon entry.
14The [blank_start]lens[blank_end] is behind the cornea, pupil, and iris which focuses the light onto the [blank_start]retina.[blank_end]
- Aretina
- Bchloric muscle
- Clens
- Dretina.
- Ehumor

15The retina turns the light into chemical signals which travel from the optic nerve to the brain so an image can be formed from its light detecting cells.
- ARichtig
- BFalsch
16Is this the process for vision?
Pupil lets light into eye-> lens changes shape and size to focus light on the retina-> the retina detects the cells and uses electrical impulses-> through the optic nerve to the brain to create a clear image- ARichtig
- BFalsch
17[blank_start]Myopia[blank_end] is short-sightedness. It is caused when the [blank_start]focal point[blank_end] of vision is too short, and the eye is too long. It is cured by a [blank_start]concave[blank_end] lens, as it pushes the focal point back.
- AMyopia
- Bfocal point
- Cconcave
18In the [blank_start]colour spectrum[blank_end] there is , red, orange, yellow, green, blue, [blank_start]indigo and violet[blank_end].

21Label this wave
- Alongitudinal
- Bcompression
- Crarefaction

22On a [blank_start]transverse[blank_end] wave, the [blank_start]crest[blank_end] is the highest point and the [blank_start]trough[blank_end] is the lowest point. The wave is situated on a midpoint or 0 line, which is the position that would be assumed if there was [blank_start]no[blank_end] disturbance. The wavelength is the [blank_start]distance[blank_end] between crests or troughs. Amplitude controls [blank_start]volume[blank_end] of a sound or [blank_start]brightness[blank_end] of a light, it is the height above the midpoint. Frequency is the amount of waves that pass through any given point in one second, controlling the colour of light (faster= violet, slower=red), or the [blank_start]pitch[blank_end] of a sound.

- Bcrest
- Ctrough
- Dno
- Edistance
- Fvolume
- Gbrightness
- Hpitch
23The electromagnetic spectrum does not include:
- AMacrowaves: electromagnetic radiation with wavelengths ranging from about one meter to one millimeter. Can only be seen under certain technology.
- BGamma rays: most powerful ray which naturally exists in the universe. Has a low frequency, and short wavelength, hence its immense speed. Visible, and damaging to the human eye.
- CInfrared: less damaging than visible light, but more damaging than microwaves. They have a mild wavelength and mild frequency. Can be visible, but only in cool, dark , situations.
- DRadiowave: the least damaging naturally existing ray of light. It has a long wavelength and frequency and is very slow. 99% of the time, invisible.
24The endocrine system:
- AHas glands: including the pancreas, pituitary gland, thyroid, parathyroid, adrenal, pineal, ovaries, and testes.
- BDoes not help with homeostaisis
- CReleases hormones; chemical messengers

27The brain and spinal chord are apart of the:
- ACentral Nervous System

28The role of the brain is to control and regulate bodily functions. It uses the cerebrum for conscious and voluntary actions, the cerebellum for balance and coordination, and the brain stem to connect the brain and spinal chord.
- ARichtig
- BFalsch
29Label this neuron
- Adendrite
- Bnucleus
- Ccell body
- Dmyelin sheath
- Eaxon
- Faxon terminal
30The reflex arc uses a [blank_start]stimulus,[blank_end] receptor, sensory neuron, i[blank_start]nterneuron[blank_end], motor neuron, effector, and response. For example, if you pricked your finger, the stimulus would be a pin, the receptor would be the nerves in the tips of your fingers, the sensory neuron carries the electrical impulses to an interneuron in the [blank_start]spinal[blank_end] chord which then goes to the motor neuron, then the hand muscles as the effector, with the response being to move the hand away.
- Aobject
- Bstimulus,
- Cthing
- Dnsideneuron
- Enterneuron
- Fbrain
- Gt4
- Hspinal
31How do we know that this is a reflex arc and not an involuntary action?
- Athe brain is not involved
- Bslower response
- Crequires a stimulus
- Dslow to adapt
32What are some hormones produced in the endocrine system, with their glands and functions?
- AInsulin/Glucagon- Pituitary gland: Glucagon breaks down glycogen to glucose in the liver. Insulin enables blood glucose to enter cells, where they use it to produce energy.
- BInsulin/Glucagon- Pancreas: Glucagon breaks down glycogen to glucose in the liver. Insulin enables blood glucose to enter cells, where they use it to produce energy.
- CTestosterone- Ovaries: Gives bone strength, and helps with reproduction.
- DMelatonin- Pineal Glands: helps with the timing of your circadian rhythms (24-hour internal clock) and with sleep.
- EAdrenaline- Parathyroid: makes your heart beat faster and your lungs breathe more efficiently.
33Hormones are very specific and as chemical messengers will not work unless they reach their target cell through blood.
- ARichtig
- BFalsch
34[blank_start]Homeostasis[blank_end] is the process of maintaining a constant and stable internal environment. It uses the [blank_start]negative[blank_end] feedback system which is a stimulus, receptor, control, and response to work efficiently. For example, if the person is too hot, their body temp is the stimulus, the [blank_start]receptor[blank_end] is the skin and brain, the control is the thermoregulating parts of the brain, the response is the blood rushes to skin. It uses the [blank_start]nervous[blank_end] and endocrine system to work effectively.
- AHomeostasis
- Bnegative
- Creceptor
- Dnervous
35The nervous system is chemical, slow, and long lasting. The endocrine system is electrical, fact, and slow lasting.
- ARichtig
- BFalsch
36What is a pathogen?

38The [blank_start]first[blank_end] line of defence is the [blank_start]chemical[blank_end] and physical barriers. The aim is to prevent [blank_start]entry[blank_end] into the body. Examples of the first line of defence include skin, hair, mucus, saliva, low ph acid in stomach.
- Afirst
- Bchemical

- Fuses leukocytes or white blood cells
40The third line of defence:

48The amount of shells tells us the period of an element, the amount of electrons in the valance shell tell us the group.
- ARichtig
- BFalsch
49An ion is an atom or group of atoms with a [blank_start]positive[blank_end] or negative charge. Ions form when atoms [blank_start]lose[blank_end] or gain electrons to obtain a [blank_start]full[blank_end] outer shell:
• metal atoms lose electrons to form [blank_start]positively[blank_end] charged ions (cations)
non-metal atoms gain electrons to form [blank_start]negatively[blank_end] charged ions (anions)- Apositive

- Cfull
