Explanation:
"Which three components are common to all amino acids? The key elements of an amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N), although other elements are found in the side chains of certain amino acids."
It is observed that the human population keep increasing significantly and it began to increase noticeably around 10,000 years ago.The greatest factor of this increase is the rapid development of the agricultures in lands, as well as the domestication of animals. These are the reasons why population increases at that time.
Eukaryotic cells have a nucleus and Prokaryotic cells do not.
Any property that describes how a substance reacts with another substance when forming a new substance is the Property of Reactivity
.
Explanation:
The ability of substance to readily react with other substance to produce new product is called as reactivity.
It describes about different methods used by the reactants to form new product.
Sometimes one single reactant gives rise to two different products as in splitting of water during which the following reaction takes place:
H_2 O →2H_2 + O
On contrary, two substance combines together to give rise to one single product as:
2 Mg + O_2 →2MgO
answer: It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA. This 'unzipping' of the molecules will expose the nitrogenous bases of the nucleic acid chain so that new nucleotides can be added to create the daughter strand.
