True/False: A virus is considered a microorganism
✔✔False — Viruses are not classified as living organisms, so they are not
considered microorganisms. However, they are often referred to as microbes, a
broader category that includes both microorganisms and viruses.
What is the smallest biological unit of life?
✔✔A cell
What are the four main types of macromolecules found in cells?
✔✔Proteins, lipids, nucleic acids, and carbohydrates
Proteins are formed from various combinations of
✔✔Amino acids
How many known forms of amino acids are there?
✔✔Twenty
How many amino acids are classified as essential?
✔✔Nine — These must be obtained through diet because the human body can't
synthesize them.
,Where can the two major types of nucleic acids be found in the cell?
✔✔DNA and RNA are found primarily in the nucleus, although RNA can also be
found in the cytoplasm.
What is the role of RNA? - ANSWER✔✔RNA , found in the nucleus is capable of
leaving the nucleus. RNA is repsponsible for deciphering the hereditary
information in DNA and uses it to synthesize proteins.
What is the role of DNA? - ANSWER✔✔DNA, found in the nucleus contains vast
amount of hereditary inforamtion, responible for inhereitable characteristic os
living organisms.
Complete the following RNA strand, and indicate how many bonds are formed for
each complementary pair:
3' GGUCAUCG 5'5' CC AGC 3' - ANSWER✔✔3' GGUCAUCG 5'5'
CCAGUAGC 3'There are 2 bonds formed between A and U, and 3 bonds between
G and C.
The plasma membrane - ANSWER✔✔Restricts movement of materials in and out
of the cell & Prevents essential nutrients from escaping
How many carbon atoms are present in glucose? - ANSWER✔✔6
True of False: The genetic material within a prokaryotic cell is contained within a
membrane-enclosed region. - ANSWER✔✔False
Only eukaryotic cells contain its genetic material within a nucleus.
True or False: Prokaryotic cells can be subdivided into Bacteria and Archaea. -
ANSWER✔✔True
, True or False: Archaea is noted for its ability to survive under harsh conditions.
Correct! - ANSWER✔✔True
Archaea can often be found in harsh conditions such as high salt levels, high acid
conditions, high temperatures and even oxygen-poor conditions.
Which of the following microorganisms are considered to be Eukarya? Select all
that apply. - ANSWER✔✔Animalia, Plantae, Fungi, Protista
Microorganisms classified as Plantae obtain most of their energy by converting
[answer1] energy into [answer2] energy. - ANSWER✔✔1. Light (sunlight)
2. chemical (sugars)
Which of the following are considered Protista? Select all that apply. -
ANSWER✔✔Algae, Amoeba
The function of the ribosome is - ANSWER✔✔Protein synthesis
True or False: Protista retain a unicellular classification, as they are unable to form
tissue layers. - ANSWER✔✔True
Where are ribosomes located? - ANSWER✔✔cytoplasm of prokaryotic cells and
in the ER of eukaryotic cells.
The combination of the cell membrane and the outer membrane is referred to as the
- ANSWER✔✔Cell envelope
