What is the cell theory?
-All organisms are made up of cell. Cells are the structural and functional unit of life. All cells come from pre-existing cells.
100
What conditions do bacteria need to grow?
food source, water, oxygen (if aerobic) and proper environmental temperatures
100
What are chromosomes?
They are the structure that contain your genetic identity. They are made up of chromatin.
100
What are the three respiration division processes?
1- external respiration 2- internal respiration 3- cellular respiration
100
True or Flase - Are plants multicellular?
True.
200
What are three characteristics that living things share?
1- all living things are made up of cells 2- living things need energy 3- living things are capable of variability and can adapt to their environment
200
What is a virus?
viruses are simply strands of genetic material (either DNA or RNA wrapped in a protein shell called a capsid)
200
How many chromosomes do people have?
46
200
What are the two types of digestion?
1- mechanical/physical digestion 2- chemical digestion
200
What are the two groups that vascular plants can be further divided into?
1- Seed plants 2- Spore plants
300
What are the two groups cells can be classified into?
Group 1-> Prokaryotes Group 2-> Eukaryotes
300
How does a virus reproduce?
When it infects a cell, animal body, or plant, the virus will inject its genetic material into a cell, taking over the cell's protein production.
300
What are genes?
A segment of DNA that codes for a particular trait; the basic unit of heredity located on chromosomes
300
What are the four stages of food passing through the canal?
1- ingestion 2- digestion 3- absorption 4- egestion
300
What are the four basic categories of tissues?
1- meristematic 2- protective 3- vascualr 4- fundamental
400
What is the cellular respiration and photosynthesis equations (just the words)?
Cellular Respiration = Oxygen + glucose -> carbon dioxide + water + energy Photosynthesis = Carbon Dioxide + water + light energy -> oxygen + glucose
400
Are viruses alive?
not technically
400
What two microorganisms reproduce asexually?
bacteria and some types of fungi
400
What are the three components of the closed circulatory systems?
1- pump 2- fluid 3- transporting vessels
400
What are the major events of sexual reproduction in flowering plants?
1- pollination 2- fertilization 3- seed and fruit formation (germination)
500
What are the four levels of structure that results in a protein's shape?
Primary structure- order or sequence of amino acids in the protein chain Secondary structure- occurs when the chain of amino acids folds or pleats Tertiary structure- occurs when there are a large number of amino acids in the chain. The chain folds back and one area of the chain bonds with another area which results in a globular protein (eg. enzymes) Quaternary structure- occurs when two or more chains (polypeptides) combine (eg. enzymes)
500
Is a virus easy to kill?
No, it's very hard to kill a virus.
500
What is the law of segregation?
For each trait an individual carries, there are two alleles. Each parent passes on one of its two alleles to each offspring. The chances of which allele is passed on is equal. If an offspring inherits two dominant characteristics, or one dominant and one recessive, it will show the dominant characteristic. If the offspring inherits two recessive characteristics it will then show the recessive trait.
500
What is an artery?
a vessel that carries blood away from the heart. Arteries branch into smaller vessels called arterioles (tiny arteries).
500
What happens during pollination?
the pollen is transferred from the male part, the stamen, to the female part, the pistil. Plants have many different ways of doing this. Pollination can be achieved by air, animals, or water. Grasses and dandelions as well as oak, maple and birch trees are examples of wind-pollinated plants.
