Answer:
a. Five-Carbon Sugar and Phosphate
Explanation:
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
There are many examples you can choose from, but one great example, a venus fly trap, and a lotus, for example. The two examples given differ because they:
*provide themselves with different types of foods
*have a different system of reproducing, as well as growing
*and live in two different types of environments.
Also, remember, the fly trap is a carnivorous plant, while the lotus is not
Answer:
A
Explanation:
firstly, conservation because by planting trees, the land dat was once proned to erosion is covered thereby conserving de land and reforestation because, u hv replaced trees dat were once cut there
Answer:
Oxygen.
Explanation:
Oxygen molecule that is produced in the light dependent reactions. This shutting down of linear electron flow greatly affected the production of oxygen. Photosystem II gains replacement electrons from splitting of water molecules into hydrogen ions (H+) and oxygen atoms so if the electron flow is disturbed then oxygen production is greatly affected.
The backbone of DNA and RNA is composed of sugar and phosphate.
DNA is double stranded due to interactions between adenine, cytosine, guanine, and thymine, which are nitrogenous bases.
Uracil is a nitrogenous base that is only used with RNA.
