geothermal plants. In your own words, explain how this would affect the
environment of the location.
Answer:
it would have a big affect because The environment around the area in Africa will be mined, drilled, or condemned. The area will be used as a resource reserve. The land around will either be damaged or conserved for further mining or sample taking.Waste water may be discharged at temperatures high enough so that utilization of the waste heat becomes both practical and imperative.

Place the events in the correct order:
____ DNA polymerase adds nucleotides in the 5’ to 3’ direction
____ Replication fork is formed
____ DNA polymerase attaches to the primer
____ Okazaki fragments are bound together by ligase
____ DNA helicase unwinds DNA
Answer:
1. DNA helicase unwinds DNA
2. Replication fork is formed
3. DNA polymerase adds nucleotides in the 5’ to 3’ direction
4. DNA polymerase attaches to the primer
5. Okazaki fragments are bound together by ligase
This is what I got.
Explanation:
The correct step order will be : DNA helicase unwinds DNA, Replication fork is formed, DNA polymerase attaches to the primer, DNA polymerase adds nucleotides in the 5’ to 3’ direction, and Okazaki fragments are bound together by ligase.
What is DNA replication?DNA replication is the physiological method that generates two identical replicas of DNA from a single original DNA molecule in molecular biology.
DNA replication occurs in all living organisms and is the most important component of biological inheritance.
Each DNA molecule contains one strand of the original DNA molecule and one strand that has been synthesized (created). As a result, DNA replication is referred to as semiconservative.
The opening of the double helix and separation of the DNA strands, priming of the template strand, and assembly of the new DNA segment are the three major steps in replication.
Extraction, quantitation, amplification, and capillary electrophoresis are the four main steps in the DNA testing process.
Thus, this is the order of the process involved in DNA replication.

What will happen to a plant cell placed in distilled water?
The cell will become flaccid due to the cell membrane.
The cell will become turgid due to the cell wall.
The cell will lysis due to the cell membrane.
The cell will burst due to the cell wall.
Answer:
the cell will become turgid due to tge cell wall
Explanation:
when a plant cell is placed in distilled water the water will move in the solution inside the cell is hypertonic to the distilled water serrounding the cell but it will not burst it producr turgor pressure keeping the plant upright
if a plant cell is placed in distilled water, and distilled water has a very low concentration of solutes the cell will become turgid due to the cell wall, hence option B is correct.
How distilled water affect the plant cell?This is because distilled water has a very low concentration of solutes and a high concentration of solvent, making it a hypotonic solution in comparison to the intracellular environment.
To put it another way, we can say that the solute concentration of When a plant cell is placed in distilled water, it becomes turgid.
This is due to the fact that it osmotically absorbs water from the hypotonic distilled water, causing the cytoplasm of the plant cell to enlarge and firmly press up against the cell wall.
Therefore, distilled water has a very low concentration of solutes, so cells will become turgid.

than the earth can create more petroleum.
System Goal 1
System Goal 4
System Goal 3
System Goal 2
Answer:
The Natural Step Framework is a methodology for successful organisational planning. It is based on systems thinking,
recognizing that what happens in one part of a system affects every other part. We begin by understanding the broader system
within which problems occur and the principles governing success within that system These principles for success then
provide a practical set of design criteria that can be used to direct social, environmental and economic actions, developing
effective, durable solutions to the environmental, social and economic issues of the new century.

Describe human use of landfills and the importance of landfill design
Human use of landfills: Landfills can safely handle non-hazardous municipal solid waste, constriction and demolition waste, land clearing debris, some industrial wastes, coal ash, sewage sludge, treated medical wastes, solidified liquid wastes and tenorm (Technologically Enhanced Naturally Occurring Radioactive Material—fracking waste)
The importance of landfill design: Modern landfills are well-engineered and managed facilities for the disposal of solid waste. Landfills are located, designed, operated and monitored to ensure compliance with federal regulations. They are also designed to protect the environment from contaminants, which may be present in the waste stream.
