Answer: These external agents of genetic change are called mutagens. Exposure to mutagens often causes alterations in the molecular structure of nucleotides, ultimately causing substitutions, insertions, and deletions in the DNA sequence.
Explanation: Point mutations are a large category of mutations that describe a change in single nucleotide of DNA, such that that nucleotide is switched for another nucleotide, or that nucleotide is deleted, or a single nucleotide is inserted into the DNA that causes that DNA to be different from the normal or wild type gene
Answer:
A. Controls what goes into and out of the cell
Explanation:
If what you are referring to is the image attached, then the answer would be A. The structure that is labelled A is called the cell membrane.
The cell membrane is what we call semi-permeable. This means that some materials can go through them and others cannot without the help of other factors. The cell membrane encases the cell and protects the cell. It lets nutrients, minerals, and waste to move in and out of the cell.
Other choices:
B describes the cytoplasm.
C describes the nucleus
D describes the vacuole
<span>Affects of geothermal plants on the environment
</span> Although geothermal plants have many advantages over other conventional fossil fuels units such as it is a renewable resource, but it has many affects as well on the environment.
Forexample
Geothermal plants discharge approximately 6.5 times as much heat, 5.5 times as much water vapours, and 0.5 times as much sulfur per unit of power produces as would a coal plant.
They also release hydrogen sulfide, carbon dioxide, arsenic, and mercury at a concentration that have an adverse but not calamitous effects.
ground subsidence is acknowledged as a potential problem.
pollutant formation may be independent of the power production rate.
Effluent pathways may change abruptly generating hazards that have not been anticipated.
Pre-operational testing and random bore holes contribute negatively to the overall impact.
Waste water may be discharged at temperatures high enough so that utilization of the waste heat becomes both practical and imperative.
