The rescue workers can get energy to the batteries in their equipment during rescue missions by using a generator to convert the kinetic energy to potential energy. Potential energy is then stored in the battery.
Reproduction rate and population size helps determine how fast the mutation is passed within a population. Also if it is favorable to species it helps determine if it is passed and unfavorable mutations tend to die off. Think about for example if one species has a favorable environment gene then it's going to have a higher chance or survival and reproduction than the other species. Also genes help determine if mutation is passed on.
Answer:
D
Explanation:
A hypotonic solution means it is less concentrated in relations to the other solution – in this case the patient’s cells. The electrolytes that balance osmotic pressure in the body are sodium, potassium, chlorides, calcium, and etcetera. The IV needs to have less electrolytes so that when the IV is injected into the patient’s blood the water can move into the cells by osmosis. Osmosis continues until the cell cytoplasm is in osmotic equilibrium with the blood. It is imporant, therefore, to have the right electrolyte balance in the IV solution otherwise the cell will over-hydrate and begin lysing – especially if the kidneys of the patient do not rid excess water fast enough.
The question is incomplete. The complete question is as following:
Conservation biologists are scrambling to put measures in place to contain the spread of lionfish. For example, Stephanie Green and colleagues measured how quickly the number of native fish would recover if varying numbers of lionfish were removed from reefs in the Bahamas. They randomly assigned 24 reefs to one of four groups and plotted the proportional change in the number native fish at six-month intervals after different amounts of lionfish (0%, 25%, 75%, or 95%) were removed. (In the graph that follows, values above 1 on the y-axis represent amounts that exceed those at the start of the study in 2009, while values below 1 indicate declines.) Compare the percentage of native fish observed in June 2011 after 25 percent versus 95 percent of lionfish were removed. What is the take-home message?
a.Removing even a few lionfish helps native fish recover.
b.Removing just a few lionfish does not help much; many of the invasive fish must be removed to help native fish recover.
c.Removing even a great amount of lionfish does not help native fish recover.
d.The biologists must find another way.
Answer: b.
Explanation:
The June 2011 green (top) data point indicates a proportional shift of about 1.7, which means that the native fish population shows very good recovery by about 70 per cent when 95 per cent of the lionfish were eliminated. By comparison, the orange (bottommost) data point at June 2011 indicates a relative shift of about 0.5, which means that when only a quarter of the lionfish were removed the native fish population decreased by about 50 percent (a result that was almost the same as when none of the lionfish were removed).
Hence, the correct option is B.
The answer is <span>Wernicke – Korsakoff Syndrome. This is a kind
of brain disorder triggered by an absence of vitamin B-1. The syndrome is essentially
two separate circumstances that can happen at the same time. Typically, people
get the indications of Wernicke’s encephalopathy first. This syndrome affects
the parts of your brain that regulate memory. Also, chronic alcohol abuse or alcoholism,
is the most common reason of WKS.</span>
