Answer:
The movement of Loess
Loess are deposits of fine particles of silt and clay formed by the wind. It is known to be a deposits form vertical cliffs which is often forms a thick, rich soil.
The movement of sand forms the Sand Dunes.
A sand dune is formed when an obstacle (rock) slows down the wind causing some sand accumulation by the wind. The dune increases in size, slowly occupying the land as more sand is deposited by saltation (deposit of more grains of sand along the gentle slope).
Inclined plane allows the same work to be done with a smaller force exerted over a greater distance.
In the student's experiment;
- the control group is bacteria grown at 98.6°F
- the experimental group is bacteria grown at 95°F, 100°F, and 108°F.
<h3>What are control and experimental groups in an experiment?</h3>
The control group in an experiment is the group which does not receive the treatment that the researcher wishes to determine its effect on a group in the experiment. The control group may receive he standard treatment.
The experimental group in an experiment is the group which receives the treatment that the researcher wishes to determine its effect on a group in the experiment.
In the experiment;
- the control group is bacteria grown at 98.6°F
- the experimental group is bacteria grown at 95°F, 100°F, and 108°F.
In conclusion, an experiment has a control and experimental group.

#SPJ1
Answer:
Answer is sigma.
Explanation:
The sigma factor can be described as protein regulating transcription in bacteria. That is, it enables the synthesis of RNA at specific locations in DNA. This specific location is known as promoters.
The sigma factor is also known as specificity factor, because, it is specific for the gene.
Transcription can be explained as the process by which genetic information in the DNA strained are copied into a new molecule of mRNA, through the aid of RNA polymerase.
It should be noted that, when there is an increase in pressure, at constant temperature, the stability of elongation complex will decrease. This means that, temperature determines the pressure at which transcription elongation stops.
Answer:
potential energy, kinetic energy
Explanation:
potential energy is the energy held by an object because of its position. kinetic energy is energy in motion. when the bow is being drawn back it has potential energy because of its position and that at any moment it can be converted into kinetic energy.
