Answer 2

It's either C or D sorry I don't know.

Answer 3

Thank you can you help with a few more? @stankytukus

Answer 4

sure what do you need

Answer 5

2. A biologist discovers a new unicellular organism and classifies it as a prokaryote. The cell is very small, contains a cell membrane, a cytoplasm, DNA in a nucleus, and no other cell organelles. Which statement below represents a correct response to the biologist’s discovery and classification? (1 point)
The organism is a prokaryote, because it lacks cell organelles such as mitochondria, Golgi apparatus, and endoplasmic reticulum.
The organism is a prokaryote, because it is so small and simple in structure.
The organism is a eukaryote, because it has a nucleus.
The organism is a eukaryote, because it has a cell membrane, a cytoplasm, and DNA.

Answer 6

The organism is a eukaryote, because it has a nucleus

Answer 7

What would most likely happen to cells placed in fresh water?
a.water would flow out of them because they are hypotonic to the external environment
b water would flow into them because they are hypotonic to the external environment
c.water would flow out of them because they are hypertonic to external environment
d.water would flow into them because they are hypertonic to external environment

Answer 8

For your Q#1

Cell is the smallest unit of life and anything less than it cannot maintain the living state.

Answer 9

For your Q#2

Prokaryotes are primitive type of uni cellular organisms which lack a membrane bound nucleus and organelles like mitochondria, Golgi complex etc.

Answer 10

For your Q#3

Cells have dissolved solutes in its cytoplasm and hence when kept in fresh water (which acts like hypotonic), water moves inside the cell.

Answer 11

Can you select correct options for each on the basis of what i just said ?

Answer 12

all but 3 and could you help with more?

Answer 13

Sure, but just to make it sure that you got it ryt...can you tell me what do you think should be the correct answers ?

Answer 14

1.b
2.a
3.b

Answer 15

1. \(\huge\checkmark\)
2. \(\huge\checkmark\)

Answer 16

For the third one, the cell acts as hypertonic to the environment (fresh water) because its solute concentration is greater. So the water moves into the cell. The correct option should be (d)

Answer 17

Oh okay! So you can help with a few more?

Answer 18

Yes, go ahead...but post them as new threads.

Answer 19

How?
