Transcript of Eoc computer review part 2

READ AND LISTEN

CAREFULLY to everything!!

You should have two windows open at

this time. One for the presentation and

one for the questions on the form. Click

the link below to get the form to open.

Orange and yellow –

tell you when to pause

Or when do click on a link

Do activity

Or answer a question.

Mitosis - Meiosis

Cell cycle has 7 parts

IPMATC –

interphase, prophase, metaphase, anaphas

e, telophase, cytokenisis.

Interphase has three parts

○ G1 – S phase – G2

Miotosis is also

known as m-phase

This chart

is the cell

cycle

Remember the

cell cycle has

ipmatc

The green

purple and

orange arrow

represent g1, s-

phase and g2.

S-phase

means

“synthesis”

phase

•Interphase

•Arrows

•G1 S-phase

G2

•Mitosis

PAUSE – answer the following

questions on the form.

What happens during interphase?

Label and write what happens during the

three parts of interphase.

Mitosis – Meiosis cont.

Which part is mitosis –

○ PMAT -prophase, metaphase,anaphase, telophase

○ This picture is metaphase

○ PAUSE the video – go to the microscopes and count the cells in Metaphase

Ask the station manager for help

Come back and put answer on the form

Osmosis Osmosis is diffusion

across a membrane

Diffusion is movement

from high

concentration to low

concentration.

PAUSE

Using diffusion – go to

“form 2” and answer

the diffusion questions

“expain why when

someone puts on lotion

you can smell it?”

High concentrationLow

concentration

With osmosis, hypertonic means there are more

solutes (solids) outside the membrane.

Water goes where the solutes are.

What happens to the cell when it is put in a hypertonic

solution?

○ PAUSE – go back and look at microscope A and

microscope B.

○ Both microscopes have a purple onion. Which onion

is in HYPERTONIC SOLUTION? A or B? How do

you know?

○ Answer on form 2

Cellular respiration

Two types of cellular respiration

One uses oxygen the other does not.

PAUSE – What are the two types of cellular respiration and

how many atp do they make?

○ Answer on the form.

Bacteria on

the head of

a needle

Looks like

Twinkies

We know that humans and

other animals use anaerobic res. and

aerobic res in the same

body.

Some bacteria don’t like

oxygen and some do.

So if you have a low oxygen

environment what organisms

are going to survive?

Bacteria!

PAUSE.

Go to the form and answer the

question, “what organisms can live in a

low oxygen environment.”

What organisms need an high oxygen

environment.

Biodiversity 1 and invasive

species The biggest reason different organisms die out (go extinct) is

because of habitat destruction.

Ex. Clear cutting

Land development

Building homes and businesses

Farming

When a habitat is destroyed the organisms die and biodiversity

goes down.

Biodiversity 2

The European

starling (left) is an

invasive species.

That means they are

not from here

They travel in huge

groups and eat all the

food.

This cause birds from

TN to starve and die.

PAUSE – go to the

form and answer the

question

“If an invasive

species of plants

grows faster than the

local plants what will

happen?”

Cells and organelles PAUSE – go to this link and study the

different organelles listed below. http://upper.usm.k12.wi.us/academics/faculty/rheun/organelle.html

While at that site study the function of… Nucleus

Mitochindria

Golgi apparatus

Rough ER

Smooth ER

Ribosomes

Chloroplasts

Cell membrane

Play the game below until you score a 90% or higher

– must show Mr. Taylor your score

GENETICS To the right is a

pedigree of a family

with color blindness.

As you can see the

females are carriers

○ The males either have

the defect or they don’t.

○ That means the defect is

“sex linked recessive”

GENETICS 2 Both the parents in the

Punnett square on the right are carriers for the disease green ear.

PAUSE – “do the parents have the disease?”

“how do you know”○ Now let us say the G represents

groovy hair.

○ PAUSE “what does that tell you about square 2 and 3?”

○ “what is the chance the offspring will not have groovy hair?”

1

The parents are

heterozygous or Gg

The sq 1 is

homozygous

dominant or GG

Sq 2 and 3 are

heterozygous or Gg

or Carriers for non-

groovy hair.

Cells use chloroplasts to

absorb energy from the sun.

PAUSE – what color do

chloroplasts reflect?

What colors do they absorb?

What is the speed of light?
