b. complex, multi-celled organisms called prokaryotes
c. simple, single-celled organisms called prokaryotes
d. complex, multi-celled organisms called eukaryotes
2. which is a true statement about eukaryotic cells?
a. they contain dna inside a nucleus.
b. they contain dna outside a nucleus.
c. they do not contain dna.
d. dna that floats in cytoplasm.
3. which characteristic do fungi cells and plant cells share?
a. they live in acidic environments.
b. they lack a nucleus.
c. they have a cell wall.
d. they contain chlorophyll.
4. what type of organisms are protists, fungi, and plants?
a. eukaryotes
b. prokaryotes
c. organelles
d. bacteria

1: C; 2: A; 3:C; 4:A

Explanation:

1 C: Bacteria are examples of simple, single-celled organisms called prokaryotes (they are unicellular organisms without a nucleus)

2 A: Eukaryotic cells have DNA (their genetic mterial) inside a compartment called nucleus (a nuclear membrane separates this DNA and other nuecleic components from cytoplasm)

3 C: Fungi and plant cells have a cell wall: it is really important in fungi for resistance of isolated cells and important in plants to give them support because they lack of a skeletal-like structure

4 A: protists, fungi and plants are eukaryotes, they have DNA inside a nucleous. They are not prokaryotes or bacteria; they have organelles inside their cells

the answer to this question is 3.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
