2.
The smallest unit of life is the _____.
(1 point)
cell
homeostasis
organism
protein
3.
The nucleus is the largest of the _____.
(1 point)
chloroplasts
mitochondria
organelles
ribosomes
6.
Which is not found in animal cells?
(1 point)
central vacuole
cytoskeleton
rough endoplasmic reticulum
smooth endoplasmic reticulum
7.
Which of these measures will not help a viral infection?
(1 point)
antibiotics
controlling animals that spread disease
improving sanitary conditions
vaccinations
8.
Organic compounds always contain ____.
(1 point)
water
oxygen
nitrogen
carbon
9.
Which of these is NOT part of an atom?
(1 point)
element
proton
neutron
electron
10.
The passive transport of water through a membrane is ____.
(1 point)
osmosis
fermentation
equilibrium
active transport
My answers:
2. cell
3. organelles
6. central vacuole
7. controlling animals that spread disease
8. carbon
9. element
10. osmosis
All of those are correct except for number 7.
Number 7: Controlling animals that spread disease is a good way of preventing viral transmission of disease. Swine flu is a good example of this. Antibiotics, however, have NO effect on viruses at all.
Hold on I just took this test.
All are correct but 7 it is antibiotics.
Thanks!

Your answers are correct!
Explanation:
2. The question asks for the smallest unit of life. The answer is "cell" because cells are the basic structural and functional units of all living organisms.
3. The question asks for the largest among given options. The answer is "organelles" because the nucleus is the largest organelle found within cells.
6. The question asks for something that is not found in animal cells. The answer is "central vacuole" because vacuoles are typically found in plant cells, not animal cells.
7. The question asks for something that will not help a viral infection. The answer is "antibiotics" because antibiotics are used to treat bacterial infections, not viral infections.
8. The question asks what organic compounds always contain. The answer is "carbon" because organic compounds are compounds that contain carbon atoms.
9. The question asks for something that is not part of an atom. The answer is "element" because elements are substances made up of only one type of atom, whereas protons, neutrons, and electrons are all subatomic particles that make up atoms.
10. The question asks for the process of passive transport of water through a membrane. The answer is "osmosis" because osmosis is the movement of water molecules from an area of higher water concentration to an area of lower water concentration through a selectively permeable membrane.
