What is the name of the incoming ray in a reflection model?
Incident ray
The basic structural unit of an organism.
Cell
The property of light that describes the fact that light travels in straight lines.
Rectilinear Propagation
A material that allows light to pass through but scatters it in the process, an object appears fuzzy through it.

The type of reflection that produces a blurry image of the surroundings
Diffuse reflection
Near sighted vision problems is corrected with what type of lens?
Concave
These two systems work together to bring glucose to the cells
digestive and circulatory
Groups of cells that have a similar structure and that function together.
Tissues
What is the name of the ray that is bouncing off the mirror in ray in a reflection model?
reflected ray
What is one positive use for x-rays?
Identifying bone fractures or breaks

This image is produced from sight lines (or extended rays)
Virtual image
What type of electromagnetic radiation has the shortest wavelength?
Gamma rays
The fine adjustment knob sharpens the view of the specimen. This is the only adjustment knob needed while using the high power lenses.
Fine adjustment knob
These are used to magnify the specimen in low power (4x), medium power (10x) and high power (40x).
Objectives Lens
These organelles are the smallest in the cell and create proteins, often referred to as protein factories
Ribosomes
What is a risk of overexposure to x-rays?
Could develop cancer
These two systems work together to bring oxygen to the cells
respiratory and circulatory
Write the order of cell organization from smallest to largest
cell, tissue, organs, organ system
This system is responsible for stability and movement of human body.
Musculoskeletal system
The part of the eye where the light is focused to form an image?
Retina
The type of reflection that produces a clear image of the surroundings
Specular reflection
This system controls the absorption and digestion of food
Digestive system
Place the electromagnetic spectrum from longest to shortest wavelength.
Radio, microwave, infrared, visible, UV, x-ray, gamma
This is a barrier around the cell. It is semi-permeable, meaning that it allows some things to enter the cell while other things are excluded. It's role is to control the entry and exit of various substances in the cell.
Cell membrane
This organelle produce energy necessary for the cell’s survival and functioning. The energy is converted from glucose into ATP (adenosine triphosphate) which is usable energy.
Mitochondria
This provides support for the internal structures of the cell. It contains the cell's organelles.
Cytoplasm
A lens that magnifies the specimen. It typically magnifies by 10 times.
Eyepiece
The stage is the location where the slide is placed for observing.
Stage
These organelles contain chlorophyll, which is required for photosynthesis.

Nervous, muscle, connective, epithelial
What will happen when white light passes through yellow glass.
Red and green light pass through and the others are absorbed.
This system controls the movement of blood through the human body
Circulatory system
This organelle is the control centre of the cell. The nucleus also stores DNA and genetic information required for cell division and growth.
Nucleus
This organelle is a network of bubbles and tubes that are either rough or smooth. It helps to modify and transport proteins.
