Question

hich technologies made it possible to maintain a controlled environment for cell cultures?

cell counter

inverted microscope

liquid nitrogen storage

incubator

Answer 1

What do you think?

Answer 2

A, C and D

Answer 3

can you choose more than one answer?

Answer 4

yes

Answer 5

Well when you think of a cell, what do we use to maintain temperatures for an organism? Like you'd usually get _______ if you wanted to hatch an egg.

Answer 6

no, my bad, i was looking at a different question, i can only pick one answer

Answer 7

don't know what you mean

Answer 10

Cell counting is any of various methods for the counting or similar quantification of cells in the life sciences, including medical diagnosis and treatment. It is an important subset of cytometry, with applications in research and clinical practice. For example, the complete blood count can help a physician to determine why a patient feels unwell and what to do to help. Cell counts within liquid media (such as blood, plasma, lymph, or laboratory rinsate) are usually expressed as a number of cells per unit of volume, thus expressing a concentration (for example, 5,000 cells per milliliter).

Answer 11

so, it's not A?

Answer 12

I do not think so no.

Answer 13

And an inverted microscope doesn't really make a controlled environment does it?

Answer 14

no i don't think so

Answer 15

it's D

Answer 16

Well we can say for sure that there are new incubation devices that work like petri-dishes but in a much more controlled state.

Answer 17

The answer could also involve the nitrogen to stop or cryogenize life?

Answer 18

What is a difference between therapeutic cloning and reproductive cloning?

Reproductive cloning produces cells that are genetically identical, and therapeutic cloning does not.

Reproductive cloning produces a living organism, and therapeutic cloning does not.

Reproductive cloning involves the transfer of genetic material, and therapeutic cloning does not.

Reproductive cloning requires cell division to occur, and therapeutic cloning does not.
