Answer:
Forensic entomology also helps determine an estimate of how long a person or animal has been deceased or the Post Mortem Interval (PMI). Investigators can determine this from insects by studying the development of the insect. An adult insect will fly around until it finds a body that is suitable for it to lay its eggs.
Explanation:
Abrasion, plucking, deposition, and physical weathering are the glacial actions which can be observed all over the park.
Explanation:
When the huge ice masses slope down to fall over the land surface during a glacier, many glacial actions or processes take place which defines the landforms formed on the surface. These actions include abrasion, plucking, deposition, and physical weathering.
Abrasion is an erosive process which scrapes the surface of ice rocks and other frozen rocky material beneath the ice and causes striations over the rocks.
Plucking also an erosive process plucks the frozen rocks beneath the ice surface.
Physical or freeze-thaw weathering causes water to enter the cracks in the rocks when the temperature increases. This water enters inside and freezes inside when the temperature goes down. This repeated melting and freezing of water destabilizes the rocks and will break the rocks.
These materials which are worn off are transported and deposition on the land surface when the glacier settle down.
Longshore drifts occur along coastlines and brings materials along the coast when waves move at an angle with the coastline.
Answer:
The answer is A.
Explanation:
The example experiment given in the question would be a valid experiment because there is more than one variable.
For an experiment to be valid, there have to be a dependent variable, an independent variable, a constant and a control aspect.
In the example, we can say that the independent variable which has the direct effect on the aspect that we are looking for, the freezing point, is the amount of salt in the water. Therefore the dependent variable is the freezing point which is the part being observed for any change. The constant can be the amount of water used because it is static and the control can be the temperature the mixtures are exposed to which does not change throughout the experiment.
Therefore the answer is option A.
I hope this anwer helps.
Answer:
With respect to antimicrobial control agents is false the statement that states that a true antimicrobial control agent is equally effective against both bacteria and viruses.
Explanation:
Antimicrobial agents are used to treat infections caused by biological agents, such as bacteria, fungi, parasites, or viruses.
These antimicrobial agents are generically called antibiotics, and have a specific mechanism of action, which is different for each type of pathogenic microbe, so there are antibacterials and antivirals.
- <em><u>Antibacterial drugs</u></em><em> -designated as antibiotics- can act on the cell wall or membrane, metabolic enzymes or the genetic material of bacteria.</em>
- <em><u>Antivirals drugs</u></em><em> act by inhibiting the replication mechanisms by which they infect the cell, as well as the destruction of the viral capsid.</em>
Currently there are no drugs that act as antibiotics to kill bacteria and viruses at the same time.
