Explanation:
hope this helps! have an amazing day lovely!
So u get a codon chart it'll look like a circle with a bunch of letters. Then you use the letters u are given for every dash such as UCU and you go biggest to smallest letter until you hit an amino acid or stop then what you write down is that amino acid you hit. For an example, we'll use UCU. You go to the big letter U inside that big U will be a smaller C and inside that C will be a smaller U which leads to an amino acid or a stop codon. And you do this with every group of 3 letters. If one is missing it stops prematurely and if there is an extra when it may have a mutation. I hope that helped! If not there are YouTube videos out there that can help.
Most bacteria live in a solution that is hypotonic relative to the cytoplasm of the bacteria. This means that the bacterial cell is constantly taking in water. The cell wall of a bacterium is a peptidoglycan polymer that is tightly cross-linked. This would therefore function to:_________-.
A. regulate the flow of most molecules into and out of the bacterial cell.
B. provide a rigid wall that prevents the cell from swelling.
C. provide a rigid wall that prevents the cell from shrinking.
D. confirm a close relationship to plant cells that have a similar structure and live in hypotonic solutions.
E. make all bacteria fairly uniform in metabolic chemistry.
Answer:
B. provide a rigid wall that prevents the cell from swelling.
Explanation:
When organisms are present in hypotonic surroundings, their cells that are in contact with the surroundings tend to gain water. Bacteria present in hypotonic solution would gain water as their cells are hypertonic than the surroundings. The entry of water would increase the volume of cytoplasm and could lead to the bursting of the cell. However, the presence of a cell wall made up of cross-linked peptidoglycan prevents the swelling of the bacterial cell and allow them to survive in hypotonic surroundings.
