organelles - tissues- organs - organ system- organism This sequence can be completed correctly by inserting

"Cells" between the organelles and tissues

In order to trap the bacteria and prevent them from going through the filter, she must make sure the pores in the filter are no larger than

1 um

Students in a different science classes carried out the same experiment. The data they obtained did not support the hypothesis that increased exercise results in increased heart rate. The most scientifically sound way to deal with this situation.

Ask students in a third class to do the experiment and see if their results support the hypothesis

More energy can be released from a fat molecule than from a glucose molecule because the fat molecule contains more

Chemical bonds

During the process of photosynthesis, energy from the sun is converted to

Chemical energy in the bonds of organic molecules

Which answer choice best explains the movement of some molecules between the model cell and the solution in the beaker

Direction of flow molecules = from high to low concentration, Energy Use = without using cellular energy

Which sequence represents structures organized from the least complex to most complex

Nucleus - nerve cell - brain - nervous system

Chemicals that help chemical reactions occur at faster rates in living organisms are known as

Organic catalysts

The shape of each of the molecules is important because

The shape of a molecule determines how it functions in chemical reactions

The most likely reason the action of the enzyme decrease after 40 degrees is that

The shape of the enzyme changes due to environmental conditions

What will the solutions in the beaker and the tubing look like after 20 minutes

The starch solution in the tubing will be blue black and the indicator solution in the beaker will not change color

Cells - x - Organs - Organ system - organism Level x most likely represents

Tissues

Only electron microscopes can be used to view

Viruses

Skin, Nerve, and muscle cells are most similar in the

information stored in the DNA

What is the nucleus's job

it is responsible for the storage of information

In a multicellular organism, organs carry out a variety of life functions. In a single-celled organism, these functions are preformed by

organelles

In the cells of the human body, oxygen molecules are used directly in the process that

releases energy

When using a compound light microscope, the most common reason for staining a specimen being observed is to

reveal details that are otherwise not easily seen
