Lab Quiz Biology

Front 1

What is the difference between null hypothesis and alternative hypothesis?

Back 1

No hypothesis is that the researchers prediction is not true, and an alternative hypothesis is when difference is true.

Front 2

What is the charge of protons neutrons and electrons?

Back 2

Protons are positive, neutrons are neutral, electrons are negative.

Front 3

How do you find atomic mass?

Back 3

Add the number of protons and neutrons together.

Front 4

Compare and contrast covalent, ionic, and hydrogen bonds?

Back 4

Covalent: strongest and shares.

Ionic: middle Strongest, Will gain or lose electrons.

Hydrogen bonds: weakest bonds

Front 5

What information is required in order that you are able to diagram an atom?

Back 5

Atomic number, protons, neutrons, and electrons.

Front 6

If the pH of a solution is 4 is it acidic or basic? What does H+ mean?

Back 6

It is acidic and H = 1*10^-4

Front 7

If H is .000001 what is the pH?

Back 7

The pH is 6.

Front 8

What is the fov, magnification, and resolution?

Back 8

Fov means field of view, what's your able to see on one slide.

Magnification is how close you are to the organism.

Resolution is how clearly you see it.

Front 9

Know the magnification of ocular and the four objectives of total magnification. For example scanning, low power, high power, and oil immersion.

Back 9

Scanning = total of 40 magnification.

Low power = 100 magnification

High Power = 400 magnification.

Oil immersion = 1000 magnification.

Front 10

How do you calculate cell size?

Back 10

Cell size equals the diameter of FOV ÷ by the number of cells across the diameter of the FOV.

Front 11

How do you make a wet mount?

Back 11

Obtain a slide, cover slip and a toothpick.

Place a drop of water, and placed a specimen in the liquid. If you are working with cells or tissues use suspending solution.

Slowly lower the coverslip on the slide to ensure there's no bubbles.

Front 12

Discuss the difference between magnification and resolution?

Back 12

As magnification goes up the field of view goes down.

Front 13

Difference between prokaryotic and eukaryotic cells?

Back 13

Eukaryotic have a true nucleus.

Front 14

What is unique to animal cells and what is unique to plant cells?

Back 14

Animal cells can move and have cilia and flagella.

Plant cells have chloroplasts and Central vacuoles.

Front 15

What are the types of Locomotion in protozoans?

Back 15

Pseudopodia, cilia, and flagella.

Front 16

Describe the three different types of bacterial cells?

Back 16

Circle rod and spiral

Front 17

What is the difference between sporangiophore and zygospore ?

Back 17

Zygo is sexual, spore is asexual.

Front 18

Which substance diffuse more rapidly?

Back 18

Potassium permanganate diffuse faster than methyl Orange.

Front 19

The weight of potassium is 158 and orange is 327 what is the relationship between the molecular weight and diffusion?

Back 19

The substance with the smaller weight diffused faster

Front 20

What is a relationship with diffusion and temperature?

Back 20

The higher the temp the faster the fuses, molecules move faster when they are warmed up causing the substance to diffuse faster.

Front 21

Learn what happens to animal cells in hyper, hypo, and isotonic solution?

Back 21

In a hyper solution the cells are shriveled up.

In the hypotonic solution the cells are clear and dots.

In an isotonic solution the cells are normal.

Front 22

Chapter nine quiz

Back 22

.

Front 23

What is the glycolysis cycle?

Back 23

Glycolysis Harvest chemical energy by oxidizing glucose to pyruvate.

Glycolysis breaks down glucose into two molecules of pyruvate.

Glycolysis occurs in the cytoplasm and has two major phases.

Energy payoff phase.

Energy investment phase.Energy payoff phase.Glycolysis occurs whether or not 02 is present.

Energy payoff phase.Glycolysis occurs whether or not 02 is present.

Glycolysis occurs whether or not 02 is present.

Front 24

Pyruvate oxid:

Back 24

After pyruvate is oxidized, the citric acid Cycles completes the energy yielding oxidation of the organic molecules.

Front 25

Krebs:

Back 25

Following glycosuria sand citric acid cycle, NADH and FADH2 account for most of the energy extracted from food.

These two electron carriers donate electrons to electron transport chain, which Powers ATP synthesis via oxidative phosphorylation.

Electrons are transferred from NADH or FADH2 to the electron transport chain.

ELECTRONS ARE PASSED THROUGH A NUMBER OF PROTEINS INCLUDING CYTOCHROMES TO O2

The electron transport chain generates no ATP directly.

It breaks down a large free energy drop from food to O2 into smaller steps that release energy in manageable amounts.

Front 26

Electron transport chain

Back 26

The energy stored in H+gradient across a membrane couples the Red Ox reactions of the electron transport chain to ATP synthesis.

The H+ gradient is referred to as proton motive Force, emphasizing its capacity to do work.

Front 27

Make sure you know the reaction of cellular respiration in general?

Back 27

Cells break down molecules for energy. In order to do this the cell uses oxygen that you breathe in and produce the carbon dioxide that you breathe out.

Front 28

I will ask you the products of anaerobic respiration as well?

Back 28

Anaerobic respiration produces and oxygen debt. This amount of oxygen needed to oxidize lactic acid to carbon dioxide and water.
