Answer:
The cascade amplifies the signal.
Explanation:
The purpose of the cascade is to transmit a signal to other components in the shortest time possible and do it massively, so when a receptor is activated, this affects a high number of receptors. By doing a cascade reaction, the information travels very fast, achieving the objective quickly, and without a significant loss of energy, in other words, is an efficient method.
Leon was a relatively successful attorney before developing schizophrenia. He has now stopped working and prefers to wander the streets in preparation for an "airlift" of humans by extraterrestrials. He has lost all his property and stays on the streets. His poverty has further aggravated his psychotic symptoms. Leon's story lends credibility to which hypothesis regarding the relationship between social class and schizophrenic symptoms?
A. Social causation hypothesis
B. Milieu hypothesis
C. Downward social drift hypothesis
D. Double bind hypothesis
Answer:
C. Downward social drift hypothesis
Explanation:
In the scenario, being described Leon's story lends credibility to Downward social drift hypothesis. This hypothesis states that there is a clear relationship between mental illness and social class, in which the illness leads the individual to have a downward shift in social class. This is the case with Leon, since he was an upper-class individual until he developed schizophrenia, which ultimately caused him to drop lower and lower in social classes. All the way down to homeless.

A series of strong storms opened a stream channel between two lakes. The western lake contains a large, diverse population of a species of minnow (these are small fish). The eastern lake has never been populated by fish. When the channel opened, a small group of fish migrated to the eastern lake. Soon after, the stream channel dried up and was never opened again. The fish in the eastern lake thrived and continued to reproduce, building a large population over time. Compared with the fish in the western lake, what characteristics would you expect the population in the eastern lake to exhibit
Answer:
Same characteristics of fishes are present.
Explanation:
Same characteristics of fishes are present in both western and eastern lakes because in eastern lake the present fish species were migrated from the western species so the characteristics of fish population will be same. If the fishes that is present in western lake are small in size so it has same size in eastern lake. Their eating behavior and other characteristic show resemblance with the fishes present in western lake.

Which of the following are formed during photosynthesis?
A. C6H1206 and 02
B. C2H4O2 and H20
C. C2H4O2 and 02
D. C6H1206 and H20
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.
Explanation:
You are designing a sustainable living space for the Mars Colony Mission. The colony will have plants growing inside of it
to recycle the carbon dioxide. You need to determine what type of lighting will be most beneficial to the plants. First you
pick a small set of sample plants and grow each in a different lighting. What is the BEST way to measure their
effectiveness?
Question Progress a
A. Measure the oxygen produced by the plant using a gas syringe,
B. Measure the pigment density in the leaves using a spectrophotometer,
C. Measure the carbon dioxide produced by the plant using a gas syringe.

Answer:
Option A is the most appropriate answer.
Explanation:
The arrangement has plants being drenched in a water container to discharge Oxygen gas that is freed and gathered in a tube placed previously. The volume of gas gathered can be utilized to find out the rate of photosynthesis and whenever coupled by methods for pH observing gadget, an expansion in pH which shows soluble alkaline means that more oxygen yield. Along these lines, this method can be utilized to then again check CO2 levels. The gas syringe is utilized to permit the oxygen gas bubbles to be gathered at the known for evacuation and estimation purposes.
This photosynthometer is combined with a hydrogen carbonate indicator evaluating CO2 levels. At neutral levels in comparing with different cases, the shading is orange and there is a progressive change to yellow shading is CO2 focus is high. At low focus, the shading turns out to be a lot darker (purplish).
Thus, the correct answer is option A.

What happens when organisms populate a new area and are isolated geographically from other populations of the same species?
Answer:
The geographically isolated population will acquire genetic differences that eventually will lead to its speciation
Explanation:
Geographic isolation is a biological process produced by the physical separation between organisms of the same species, which may be caused by different types of geographical barriers such as, among others, mountains, earthquakes, rivers, etc. Geographic Isolation produces genetic differences between the separated groups. Over time, these genetic differences will lead to the reproductive isolation of the new population, thereby leading to the formation of a new species in the course of evolution, in a mechanism referred to as speciation.
9. A finch population has genetic diversity. Some of the finches have an allele that gives them
longer beaks. Due to pollution, the ecosystem changes and seeds become harder to find. The
finches with long beaks can dig the seeds out more easily than the finches with short beaks.
a) Which type of bird is selected for in the polluted ecosystem?
b) How will the allele frequency change in the finch population?
c) is this an example of natural selection explain
Answer:
A) the finch with the longer beak
B) the allele will continue to become more prominent as the smaller beak birds die off
C) Yes, the birds with the longer beaks will continue to live on because the birds with the smaller beaks can’t find the seeds as easily.
Explanation:
Seeds are harder to find, so finches with larger beaks get selected in a polluted environment. This is a natural selection. If this continues, then the alleles for short beak will vanish.
What is natural selection?
Natural selection is a process in which nature selects an organism that can fit well. If an allele is selected in a population and present for a longer time, then it replaces other alleles in that population. Example: In a population, both short-beaked and long-beaked finches are present.
Due to pollution, long-beaked finches are able to find more seeds than short-beaked finches. Here, nature favors long-beaked finches over short-beaked finches. If this continues for a longer generation, then alleles for the short beak will vanish. Only alleles for long beaks will be in the population.
Hence, long-beaked finches are selected. It is an example of natural selection. The allele frequency of the long beak will increase while decreasing for the short beak.
