A cell with 32 chromosomes splits in two and each half contains 32 chromosomes.
What is mitosis?
100
Food coloring penetrates a smaller potato cube faster than it penetrates a larger potato cube.
What is the smaller cube has more surface area compared to volume?
200
Water moves across a cell membrane from areas of higher concentration of water to lower concentrations of water.
What is osmosis?
200
It becomes more compact to fit in a cell by wrapping tightly around histones.
What is DNA?
200
A substance made up of a phosphate head with two fatty acid tails.
What is the basic buiding block of the cell membrane?
200
The phase of mitosis whereby the chromosomes line up along the middle of the cell.
What is metaphase?
200
A compound that is found in living things and supplies the energy in one of its chemical bonds directly to cells
What is ATP?
300
The concentration of salt outside the cell is 80% and the concentration of salt inside the cell is 60%.
What is hypertonic?
300
A process whereby an mRNA strand is copied from the cell's DNA strand.
What is transcription?
300
Rod-like structures made of DNA and proteins
What are chromosomes?
300
A phase of mitosis whereby the cell is pinching in half to form two cells, each with an equal number of chromosomes.
What is telophase?
300
He built the first microscope, which allowed people to see things no one had ever seen before, such as bacteria, sperm, and red blood cells.
Who is Anton van Leeuwenhoek?
400
Channel proteins are used to transport substances across the cell membrane.
What is facilitated diffusion?
400
The process of modifying the DNA in a living thing.
What is genetic engineering?
400
Organelles used to make energy and found only in plants
What are chloroplasts?
400
Four daughter cells are formed each with half of the number of chromosomes as the parent cell.
What is meiosis?
400
Needed to ensure that chemical reactions in a living organism do not occur too slowly.
What are enzymes?
500
Proteins are not used to transport substances across the cell membrane.
What is regular diffusion?
500
A process where the code on an mRNA strand is read for a particular amino acid.
What is translation?
500
The levels of organization in multicellular organisms, from most complex to least complex
What is organ system — organ — tissue — cell?
500
Chromosomes are moving from the middle of the cell to opposite ends along spindle fibers.
