Answer: Exhaled air containing Carbon dioxide bubbles react with water to form carbonic acid . The solution turn acidic and turn from green to yellow.
Explanation:
Exhaled carbondioxide bubbles reacts with water to form carbonic acid, the solution will turn acidic. Carbonic acid is a weak acid that decrease pH. An indicator of it shows that the solution turns from green to yellow.
Co2+ H2O= H2Co3.
The solution then dissociate to give H ion and hydrogen carbonates ion.
A peptide bond is a chemical bondformed between two molecules whenthe carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Answer:
The factors limiting the size of cells include: Surface area to volume ratio (surface area / volume) Nucleo-cytoplasmic ratio. Fragility of cell membrane.
Explanation:
mark me as brainliest pls :)
DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.
Explanation:
do number one like that and do number two different
that is systems with essentially only two energy levels are
important kind of systems, as at low enough temperatures, only the two
lowest energy levels will be involved.
