D. Infrared images can show hot spots as red areas.
It is C; to have fought over something trivial
Conservation of Energy:
As a projectile is launched into the air KE is at its maximum. As the projectile gains altitude PE becomes greater than KE. At the top of its arc, PE is at its maximum. The whole cycle reverses itself on the way down.
Answer:
1) c. five
2) a. lysine and arginine
3) g. two
4) d. four
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.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and then condense it to chromatin.
Histones include five main classes of relatively small basic proteins containing relatively large amounts of lysine and arginine. Nucleosomes are made of two each of four types of histones.
The process of osmosis explains what happened to the cells.
Osmosis is where water molecules will flow from a region of higher water potential to a region of lower water potential, through a partially permeable membrane. Red blood cell is a human cell and have a partially permeable membrane. At the same time, pure water has the highest water potential among all substances, and of course higher than the cytoplasm of the red blood cell, therefore, water molecules will flow from the water to the red blood cell.
So much water has flown to the red blood cells that the cell membrane cannot hold all and eventually the cell bursts. Therefore, the process of osmosis explains this result.
