Many years ago, scientists believed that organisms "spontaneously generated " into existence. Scientists now know that is not the case. What changed?

• One scientist tells all other scientists when we should adopt new scientific theories and laws.

• Old ideas are often wrong and new ideas are often more correct, so we always throw away our old ideas when new ideas come along.

• The people who proposed new scientific ideas were so popular that the scientific community just believed them to be true

• New evidence was discovered through observation & experimentation which supported new ideas such as classification and evolution.

Answer explanation

Science is always changing as new observations and discoveries are made. that is what makes science durable.

in this case, the experiment with the meat helped scientists recognize that living things must come from other living things.

A group of scientists has posted their findings from their recent observational studies in the tropical rainforest. One scientist in the group reported very different findings than the other scientists in the group. What should happen?

• They should throw out all results and start over.

• They should change their results so they all have matching results.

• The scientists should discuss their findings to see why their results were different.

• Claim one team members findings as wrong and everyone else' s results as correct.

Why, as we move down the classification chart, are there fewer and fewer organisms?

• At the higher levels of classification, organisms are more closely related

• At the lover levels of classification, the organisms are more closely related and therefor there are fewer organisms in that group.

• Higher levels of classification has smaller organisms

• Lower level of classification has organisms that are more complex.

Answer explanation

The top of the chart is wide and broad and includes many organisms, then as you move down the categories get more and more specific so the classification narrows until you have only 1 organism.

I live on land. I can't move around freely, I can not make my own food and I decompose other organisms for energy. What kingdom do I belong to?

• Protista

• Animalia

• Bacteria

• Fungi

Answer explanation

fungi are multi-cellular land dwelling, decomposers who grow but don't move around freely.

Plants and fungi both grow in the ground, yet the are different in many ways. What are some main differences between the two kingdoms?

• Plants are multi cellular, fungi are not.

• Plants can't make their own food.

• Fungi can move freely

• Plants make their own food, but fungi don't.

Answer explanation

Plants are AUTOTROPHS, but Fungi are HETEROTROPHS who must consume food to survive..

A long time ago, scientists used to classify plants and fungi in the same kingdom. What do you you think occurred that prompted scientist to give them their own kingdoms?

• New evidence supported that they were not as related as previously thought and they were reclassified.

• The plant kingdom was too large so scientists decided to break them up into smaller groups.

• Advancements in technology supported that plants and fungi are very closely related.

• Plants and fungi are still classified in the same kingdoms to this day, because they are so closely related.

Answer explanation

New evidence supported that even though plants and fungi they may look similar, they are very different.

I am and AMOEBA. I move freely and I have to eat to survive, but I do not fit in the animal kingdom because I am unicellular. Where would you classify me?

• Kingdom FUNGI

• Kingdom PLANTAE

• Kingdom PROTISTA

• Kingdom HOMOSAPIEN

Answer explanation

Protists are often seen as animal like plants or plant like animals, but because the are single celled, they don't fit into those kingdoms.
