Question

viruses can best be described as
a)genetic material wrapped in a protein coat
b) a samll, solid ball of infectious protein
c) primitive type of bacterial cell
smallest typr of living cell

Answer 1

@InYourHead i know it is not C

Answer 2

Are viruses and cells the same thing? Or are they different?

Answer 3

virusses are cells

Answer 4

They're not.

Answer 5

Think about all the things that are inside of our cells.

A nucleus. Ribosomes. Mitochondria. All these different organelles.

Do viruses have any of those things?

Answer 6

no

Answer 7

Nope.

Viruses are not cells.
They can INFECT cells. But they're much smaller than cells.

Answer 8

So it's not C.

What else is it not?

Answer 9

D

Answer 10

I think its A?

Answer 11

Yep. It's A.

Here's a picture of a virus:
http://img.tfd.com/dorland/thumbs/nucleocapsid.jpg

It has three main parts.

1. Genetic material (which can be DNA or RNA)
2. A protein coat, called a "capsid."
3. A lipid envelope, which is a bubble that surrounds the capsid.

Some viruses don't have a lipid envelope.
But it's pretty simple.

Answer 12

@InYourHead okay thanks for that but now some questions i am just going to write them and answer it ans u can just check the for me plz cause my teacher is not gonna go over this

Answer 13

Alright.

Answer 14

1)Viruses are
photosynthetic
chemosynthetic
parasitic
all of above
my answer- D

2) which is the result of conjugation
nucleotide brak down
rapid cell reproduction
genetic diversity
endospores creation
my answer- C?

Answer 15

Archea and bacteria differ because of their
nuclei
cell walls
flagella
organelles
I am not sure about this one

Answer 16

@InYourHead

Answer 17

I agree with your answer for #2.

Answer 18

1 and 3?

Answer 19

No.

Answer 20

Well you didn't even answer 3.

Answer 21

i dont know 3

Answer 22

Do you know what photosynthesis and chemosynthesis are?

Answer 23

yes phto-is sunlight and that's how it is made using sunlught,chemo-like elements ans molecules and all that is used in the process

Answer 24

Yes. They're both ways to make food.

Are viruses alive? Do they need food?

Answer 25

no

Answer 26

Well then I guess they don't use photosynthesis or chemosynthesis. Does that make sense?

Answer 27

ya so it is C

Answer 28

Yes. Process of elimination.

I'll tell you something about viruses:

They can't make copies of themselves, on their own. They need to use our cells, to do this.
And after they're done using our cells, they destroy our cells.

That sounds a lot like a parasite.

Answer 29

for #3 it is either B or D

Answer 30

Here's a picture of the cell walls of bacteria:

Take a look on the Left side.

You see that big brown block?
That's called "peptidoglycan."

Archaebacteria don't have peptidoglycan in their cell walls.

Answer 31

so it is B

Answer 32

Yes.

Answer 33

okay i think this is the last one

Answer 34

bacteriophage:bacteria::
a) photosynthetic bacteria:chemosynthethis bacteria
bateria:viruses
antibiotics:bacteria
virus:host

Answer 35

c?

Answer 36

Do you know what a bacteriophage is?

Answer 37

yes virusses that infect bacteria

Answer 38

So why did you pick...C?

Answer 39

cause viruses infect bacteria the same way bacteria are killed by antibiotics

Answer 40

I can see how you made that connection.

Look at it this way:

Bacteriophages are pathogens.
They infect bacteria.

All pathogens infect a host.

So, we want to pick a choice that includes a pathogen, and a host.

Answer 41

d?

Answer 42

Yeah.

Answer 43

A "host" is something that gets infected.

Answer 44

then what do u cal that 1 animal/human that gets infected 1st?

Answer 45

Do you mean when we're looking at a whole crowd of infected people, and we want to find the one person who was infected first?

Answer 46

yes

Answer 47

That person is called the "index case."

Answer 48

okay
so bacteria cells have both a cell memberane and outer cell wall right?

Answer 49

Yes.

Answer 50

which of the following can be found in the cytoplasma of a bacterial cell?
chloroplats
golgi bodies
mitochondria
none of above

Answer 51

D?many be not sure

Answer 52

yeah i am sure about D

Answer 53

Yes.

Answer 54

the chromosomes of bacteria
contains numerous types of organells
are divided into compartments
vary on number depending on the species of bacteria
contain single circular pice of DNA

Answer 55

B OR D?

Answer 56

i think D more than B

Answer 57

I would go with D myself.

Answer 58

If you have anymore questions, you can make a separate post. I do have to leave now.

Answer 59

okay byeeee thanks :)

Answer 60

@inyourhead long time

Answer 61

good to see you again girl so watsupppppppppp @inyourhead

Answer 62

No. I'm not doing this.

Answer 63

It's a.
