BIOLOGY
How many things does cell theory tell us? (number)
3 which are
All living things are made of cells
Cells are the basic unit of life
3. All cells come from preexisting cells
What is ecology?
The study of how living things interact with the environment
What does the circulatory system do?
Pumps blood throughout the blood
What is the main goal of the respiratory system.
It helps you breathe!
This is the first organ food enters in the digestive system, where both mechanical and chemical digestion begin.
What is the mouth?
Which cell has a cell wall?
Plant Cells
Difference between Biotic factors vs abiotic factors
Biotic factors - living parts of an ecosystem
Abiotic factors - nonliving parts of an ecosystem
How does this system maintain homeostasis?
It controls the nutrients that go into cells and takes away the waste.
How does the respiratory system maintain homeostasis?
It allows for the exchange of gases in the blood.
This organ produces bile to help carry away waste and breaks down nutrients to maintain balance in the body.
What is the liver?
Are plant and animal cells? Prokaryotic or Eukaryotic
Eukaryotic
What is a carrying capacity?
A carrying capacity means there is a limit to the number of organisms a population can have./
What is the role of the pulmonary artery to the lungs?
It exchanges oxygen poor blood with oxygen rich blood.
How does your oxygen rich air go into your lungs
Bronchi and bronchioles
This organ produces bile to help carry away waste and breaks down nutrients to maintain balance in the body.
What is the liver?
What do Lysosomes do?
it breaks down wastes
What is a niche?
an organism’s role in its environment
Where does oxygenated blood reenter the heart after it becomes rich with oxygen.
Left atrium
What are the two things that connect your throat to your lung?
Pharynx (throat) and trachea
Most nutrients are absorbed in this part of the digestive system, which contains tiny fingerlike structures called villi.
What is the small intestine?
What is the difference between (smooth er) compared to (rough er)? Endoplasmic Reticulum (ER)
Smooth ER - has no ribosomes, creates lipids
Rough ER - has ribosomes, creates proteins
What are each of these and how do they correlate? An individual, A population, A community.
An individual is one organism
A population is a group of individuals that all belong to the same species such as a group of fish
A community is various multiple populations all in the same area
What does the aorta do?
It carries oxygenated blood to the rest of the body, where blood vessels called capillaries transfer it to cells.
Describe the process that happens in the alveoli.
The alveoli pass oxygen into the blood, which goes back to the heart.
The digestive system helps the body maintain this internal balance by breaking down food and absorbing nutrients.
What is homeostasis?
