climate change?
100

what are 5 clues of a chemical change

A new colour appears, bubbles of gas formed, a precipitate forms, heat/light produced, irreversible/difficult to reverse

100

what organ system is responsible for transporting nutrients, water, and waste?

circulatory system..?

100

what is reflection/refraction

reflection is light bouncing off a surface/refraction is the BENDINGGG of light off a surface

100

what can muscles in the eye do?

muscles in the eye can change shape of lens + size of the pupil

100

difference between weather and climate

weather is the temperature/conditions at a place and time

climate is average weather conditions in a region over a long period of time

NAME THE REACTIONS

1. A+B=AB

2. A + BC = AC + B

3. AB = A + B

4. AB + CD = AD + CB

1 = synthesis

2 = single displacement

3 = decomposition

4 = double displacement

200

what are accessory organs (for each system)

circulatory = lungs, spleen, blood vessels, bone marrow

respiratory = nose, pharynx, larynx, bronchi

digestive = liver, pancreas, galbladder, salivary glands, teeth, tongue

200

differnence between diffuse mirrors and plane mirrors

plane mirrors = clear image, specular reflection

diffuse mirror = distorted image, diffuse reflection

200

what is the lens

focuses light onto the retina

200

what caused more CO2 in atmospheres

burning of fossil fuels, driving cars, factories, etc

300

which number on the pH scale is represents a neutral substance

7

300

What is cell differentiation 

a process that allows specialized cells to develop from unspecialized cells 

300

examples of both concave (converging), and convex (divergng) mirrors

concave - spoons, vanity mirrors, telescopes

convex - surveillance mirrors, car mirrors, side ons

300

what types of photo receptor cells are in the retina + explain them

rods are sensitive to light intensity + more rods can pick up lower levels of light easier, nocturnal

cones detect wavelengths of light, diff light wavelengths = diff colours

300

what is the greenhouse effect

greenhouse effect = natural process where gases + clouds absorb infrared radiation from Earth's atmosphere, radiate it back, some gets trapped keeping Earth's surface, and atmosphere

400

what is the law of conservation of mass



total mass of reactants equals total mass of products


400

which side gives/recieves deoxygenated, and oxygenated blood

blood from heart to lungs is deoxygenated (blue blood), from lungs to heart is oxygenated (red blood)

400

examples of indicators to test acidity/basicity

litmus paper = red in acid, blue in base

bromothymol blue = yellow in acid, blue in base

methyl orange = red in acid, yellow in base

400

what is the red eye effect

when a light flashes and a large amount of light enters the pupil so quickly that the iris doesnt have time to adjust so light reflects off blood vessels in the retina and u see the red eyes

400

what was the Conference of Parties 21 Paris Ageement of 2015

was 2 limit global warming to below 2 degrees calcius, globally reduce greenhouse gas emissions, net-zero emissions goal by 2nd half of 21st century, support developing countries with climate finance, technology + capacity building

500

what is the word eq: methane + oxygen = carbon dioxide + water

as a chemical eq (bonus: balance)

Ch4 + O2 = CO2

Ch4 + 3 O2 = CO2 + 2 H2O

500

define malignant tumour, benign tumour, carcinogen

malignant tumours = bad + harmful, benign tumour = bad + not harmful, carcinogen = cancer causing substance

500

what is total internal reflection?

total internal reflection is when light travels from more dense to less dense medium at an angle more than the critical angle (causing light to reflect entirely w medium)

500

label eyeball from left to right (start to finish)

cornea, iris, pupil, lens, retina, optic nerve

500
what is ocean acidification 

ocean acidification is is an evironmental issue caused by too much CO2 from the atmosphere dissolving in seawater which makes it harder for corals + shell building organisms to survive
