What are the key components of data collected from experiments?

What information do the axes have?

Why are units on data results helpful?

Which axis should time be placed on?

What kind of graph should height use?

What type of graph is used with countious data?

Do you create a line or bar graph?

What graph is best when dealing with magnitude?

You are told to create a pie chart?

How should a piechart be drawn?

What do you call units of millionths?

What are 10 -6 meters?

what does surface area to volume ratio represent?

What increases volume and how does it relate to surface area?

What does each prefix represent?

What does the unit 'kilo' represent?

What notation way can you write small and large number?

What is the name for the way large numbers were written?

What's the difference between instrumental error and mistakes?

What is the difference between error in instruments and mistake that the experimenter didn't mean to make?

How do you handle anomalous observations?

What do you do with anomalous observations?

Name 4 apparatus for measuremet.

What 4 things do you measure?

What does splint test for?

If a splint glows, what has it found?

Why can't drawing look artistic?

Why does it need explanation?

Binomal system: features?

What are features?

What is a taxon?

What is each taxa?

Dichotomous keys: key points?

What considerations are there?

Virus structure (2)

Protein and genetic material

Visible?

External characteristics only

Four classes outside vertebrata?

Name four phylums

Basic levels or organisation:

Cell, tissue, matrix

Define diffusion

Movement of fluids

Energy for dissusion?

Little

diffusion = 4 factors

Temperature, conc, area, distance

HYPOtone =

Dilute solution

Active transport?

Higher conc to lower conc, carrier protein

Active diffusion -examples:

Ions of minnerials, glucose of epthelial and kidney

Small to big: carb?, what to prot?

Glucose, ammino acids to protien

Role of carbs, protein and lipids respectively

Energy, immune and make bodies

DNA = ?

Two strands with complimentary base pairing

Food test - name 3

Reducing sugar (benedicts), starch iodine, fats (alchol)

Enzyme->substrate-product: carb example

Amylase, malate

Denaturation cause?

Temp up, ph extreme

Germination enzymes do x3

Amylase helps the seed, proteus help the seed and so does lipase

Enzymes: biological washing powder test: what does?

Digestion = prorease and carbs

DIET = total intake of … organic and inorgnic

The amount of everything eaten

autotrophic vs heterotrophic

Inroganic vs orgranic molecules

Inner Leaf - structure = function

Structure-> function. Cuticle, stomta, cholorphy

Stomata slide = ?

Upper and lower is covered in nail polish

Mineral salts for leaves…

N, mg, phosphate

To Investigate: What do we test is needed?

Cholorphyl light and CO2

Graphs - what is ideal level as a factor?

Too much and too little

Greenhouse? Control these three factors

Temp controlled, light controled and Co2 controled

Nutrient?

Uptake, not creatin

Gut - part ->process?

HCL, enzyme, villi

V Cholera?

Vibrio cholera creates toxin = diarrhea

Enzyme properties/def

Active site, optimum temp, catalyst, over and over again

Role of bile and emulsificaiton and fats

Fatty acid and gloseral makes fats and glycerol break up big fats to be smaller

Absortion to the blood with what?

In blood: nutrients, lungs, intestine (villi)

What happens to left over food/?

Liver (metabolism for reuptake, and amino asids)

H2 = taken up

Water and CO2

Xylem = ALL transport?

All,

transpiration: cut under water, cut a slant?

To not let in air bubbles and to make slope increase amount going up

Lymp = ?

Vessels

Good vessel characteristics:

Arteries->A way!, arterieolrs, valves, capillaries(small for good transfer)

All blood

Red cells, white cells and small clots

Plasma transport what?

O by blood cell, waste by plasma

Ex vs In, gut

E -> muscle up. G = G

Famine = what not to have distributed unqually…

It allows all to be removed

Starch test, why do certain procecsses?

Ensymes for starch, heat kills all

Urea = 2 chems

Ammonia becomes urea

Hormones + alchol all broken then excrete

Ammonia can be taken away

Dailysis test

Tubules - what do they look like to test it?

Reason for life! What should it be?

Energy then make babies

Cell make-up - why?

Stimili make different cells

Asexual 1 parent - sexual 2

Asexual make no one,

Disadantage asexual and sexually for stability

Less stable = risk

sexual - inside and outside

Pollen, sticky outside and not and smelly and not

DNA 1 and 1, best

H bonds for the best of the best

Blood is equal.

We are like all people, 2

Alchol drug vs drugs all - effects? good points?

Drugs - no for all. Alchol is good for small
