where will the water go?

A)equally in and out - equilibrium

B)into the cell

C)out of the cell

Answers

Answer:

c) out of the cell

Explanation:

The process of osmosis is the diffusion of water across a membrane. It is crucial for organisms to balance water between themselves and their surroundings.

Since this cell is placed in a solvent containing more solutes than inside the cell, the cell is considered to be in a hypertonic solution, and thus will expel water out.

How are genetic code and gene expression similar?

Answers

Answer: Gene expression is the process the cell uses to produce the molecule it needs by reading the genetic code written in the DNA. To do this, the cell interprets the genetic code, and for each group of three letters it adds one of the 20 different amino acids that are the basic units needed to build proteins.

Answer:

Gene expression is the process the cell uses to produce the molecule it needs by reading the genetic code written in the DNA. To do this, the cell interprets the genetic code, and for each group of three letters it adds one of the 20 different amino acids that are the basic units needed to build proteins.

Explanation:

Non-protein-coding genes (genes that specify functional RNAs) are still transcribed to produce an RNA, but this RNA is not translated into a polypeptide. For either type of gene, the process of going from DNA to a functional product is known as gene expression

A project about How do vaccines be used to fight outbreaks please someone help i'll give brainlist​

Answers

Answer:

building up antibodies in the immune system of those who get a vaccine

Explanation:

A vaccine is a small amount of the live virus being fought, given in such a small amount that is will not get you too sick for your body to fight it off. By inserting that small amount of the virus into the body it can build up its immunity to that virus. This means if the immunized body gets exposed to the virus later it already has its antibodies built up to fight off the virus in full. think of it as a set of instructions on how to get rid of this thing that is attacking you.  when mass quantities of the vaccines are spread through a population, the virus has a lesser probability of making lots of people badly sick. But the vaccine will only do its job if a lot of people get it.
