answers correctly solved 2025
Cells - correct answer ✔The smallest most basic unit of life
In Multicellular organisms, similar cell combine to form _____ - correct
answer ✔tissues
Examples of multicellular - correct answer ✔Plants
fungi
animals
Majority of organisms on the planet are ____
A. single celled
B. Multicellular - correct answer ✔single celled
Give and example of an organ system - correct answer ✔the heart and the
blood vessels for the cardiovascular system
Fill in the blank (smallest to biggest):
cell---_____-----_____----_____----______----- organisms - correct answer
✔Cell
Multicellular Tissues Organs
Organ systems Organism
Metabolism - correct answer ✔all the chemical reactions that occur in a cell
,Define homeostasis as it relates to living organisms and explain its
importance. Provide one example of a condition in humans that is regulated
by homeostasis. - correct answer ✔Homeostasis is the regulation of internal
conditions despite external fluctuations. When homeostasis fails, diseased
states or death can occur.
Examples might include blood sugar, pH, temperature, etc.
Living organisms find energy and/ or nutrients by doing what - correct answer
✔interacting with their surroundings
can bacteria and other types of single celled organisms simply split in two -
correct answer ✔Yes
The kingdom protista is in what group of organisms?
A. Eukaryotic
B. Prokaryotic
C. Both - correct answer ✔Eukaryotic
Are Protista single celled or multicellular - correct answer ✔single
Fungi help decompose what - correct answer ✔dead organisms
Give examples of fungi - correct answer ✔molds, and mushrooms that, along
with many types of bacteria
List the 4 types of kingdom - correct answer ✔Protista
, Fungi
Plantae
animalia
Animals are
A. Singlecelled
B.Multicellular - correct answer ✔...
Plasma membrane (Cell Membrane) - correct answer ✔this is the outer
membrane of all cells. Acts as a boundary b/w the outside and inside of a cell.
(Gatekeeper) it is like a night club, the plasma membrane is selective to who
or what gets in.
Why are Cells so Small? - correct answer ✔It would take a long time for
material to diffuse into a cell if they were large. Because they are small they
are able to keep the same volume but increase in surface area. (less distance
for material to move in and out of the cell.
Prokaryotic - correct answer ✔lack a nucleus/ really only consist bacteria
and Archaea bacteria (simpler and size of a mitochondria)
Eukaryotic - correct answer ✔has a nucleus/ are things we think are alive Ex.
Plants, Animals/ has organelles aka organs within the cell Ex. mitochondria
Nucleolus - correct answer ✔Found within the nucleus/ produce ribosomes
or where they are assembled
