Ecosystems

100

*DOUBLE POINTS*

This organism makes its own food using photosynthesis.

Producer or Autotroph

200

This term describes all the living and nonliving things interacting in an areaa.

Ecosystem

300

This is the vessel that transports sugars in a plant.

Phloem

400

Lichens and mosses during succession are known as...

Pioneer species

500

One different in monocots and dicots is the number of petals on their flowers, monocots usually have...

multiples of 3 petals (3, 6, 9...)

Microbes

100

These microorganisms are used to make yogurt and cheese.

bacteria

200

Unlike bacteria, these microbes require a host cell to reproduce

viruses

300

This is why overusing antibiotics is dangerous.

Antibiotic resistance

400

This process allows bacteria to reproduce rapidly by splitting in two

Binary fission

500

*DOUBLE POINTS*

These are the 6 requirements for natural selection to occur. 

1. High population numbers

2. Variation due to mutation

3. Competition for resources/against predators

4. Adaptations of the successful organism

5. Differential Reproductive Success

6. Can pass genes on to offspring

Inheritance

100

Different forms of the same gene are called...

Alleles

200

*DOUBLE POINTS*

An organism with two identical alleles for a trait is described as...

homozygous

300

If a heterozygous organism shows both alleles equally, this inheritance pattern occurs.

codominance

400

A woman with blood type AB and a man with blood type O can produce children with these two blood types

Blood Type A or B

500

Allopatric speciation is...

When members of a population are geographically separated.

Mitosis, Meiosis and Fertilization

100

This type of cell division produces gametes.

Meiosis

200

This stage of mitosis lines chromosomes up in the middle of the cell.

metaphase

300

*DOUBLE POINTS* 

Crossing over occurs during this phase of meiosis.

Prophase I

400

This is the cell made when two gametes fuse.

Zygote

500

How many possible gametes can be formed by a human with 23 pairs of chromosomes? (ignoring crossing over)

2²³ = 8,388,608 

The Human Body

100

This organ pumps blood throughout the body.

The heart

200

Gas exchange occurs in these tiny air sacs of the lungs.

Alveoli

300

This blood vessel carries oxygen-rich blood away from the heart

Arteries (accept: aorta)

400

*DOUBLE POINTS*

This is the reason the signal pauses at the AVN.

To allow both ventricles to fill completely.

500

This process links the respiratory and circulatory systems by allowing oxygen to move from the lungs into the blood.

gas exchange (diffusion in the alveoli)
