edge 2020
Volcanic eruptions that occur as a result of continental shifting are typically found where the crust is thinned and the tectonic plates diverge. Thus, the correct option for this question is B.
What do you mean by Continental drift?Continental drift may be characterized as a type of hypothesis that involves the significant movement of continents across the earth's surface through geological time. This theory of continental drift was given by Wagner.
The movement of the earth is stimulated through the divergence of tectonic plates which remains the foundation for the shifting or the occurrence of continents. These tectonic plates diverge by sliding over the surface of one another.
Therefore, volcanic eruptions that occur as a result of continental shifting are typically found where the crust is thinned and the tectonic plates diverge. Thus, the correct option for this question is B.

1. Name and describe each of the 3 major processes in the water cycle.
2. Describe the properties of ocean water.
3. Describe the 2 types of ocean currents.
4. Name the 2 types of freshwater and describe how they can be stored.
Answer:
evaporation, condensation, and precipitation. Evaporation is the process of a liquid's surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor. condensation water which collects as droplets on a cold surface when humid air is in contact with it. Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain. properties of ocean water.Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. The two basic types of currents – surface and deep-water currents – help define the character and flow of ocean waters across the planet.On the landscape, freshwater is stored in rivers, lakes, reservoirs, and creeks and streams. Most of the water people use everyday comes from these sources of water on the land surface. Lakes are valuable natural resources, both for human and non-human life.

If there was not an increase in cyanobacteria in early Earth, what would have happened to Earth’s early atmosphere? A. The amount of oxygen would have increased, causing an increase in aerobic autotrophs and heterotrophs B. The amount of oxygen would have increased, causing a decrease in aerobic autotrophs and heterotrophs. C. The amount of oxygen would have decreased, causing an increase in aerobic autotrophs and heterotrophs. D. The amount of oxygen would have decreased, causing a decrease in aerobic autotrophs and heterotrophs.
Answer:
Explanation:
Anaerobic bacteria are able to survive in the absence of oxygen while aerobic bacteria survive only in the presence of abundant oxygen.
Hence, while reduced levels of dissolved oxygen in the pond decrease the amount of aerobic bacteria like Bacillus; anaerobic bacteria like Actinomyces flourish since they survive on organic substances like methane, cellulose instead.

What is the difference between a hypothesis and a theory? A hypothesis is a testable statement, and a theory is well-supported explanation. A hypothesis is a theory that has been proven. A hypothesis is a law of nature, and a theory is always true. A hypothesis is an observation that can turn into a theory.
Answer:
In scientific reasoning, a hypothesis is an assumption made before any research has been completed for the sake of testing. ... A theory on the other hand is a principle set to explain phenomena already supported by data.
Explanation:
The main difference between a hypothesis and a theory is that a hypothesis is a testable statement, and a theory is a well-supported explanation. Thus, the correct option is A.
What are Scientific theories?A Scientific theory may be characterized as a well-determined description of some significant features of the natural world, based on a body of certainty that has been repeatedly assured through observation and experiment.
The theories can transform themselves into laws when they gather sufficient evidence. While a hypothesis is a testable statement that needs sufficient evidence to be proved. A hypothesis is never turned into theories until they have some evidence to support the claim.
Therefore, the main difference between a hypothesis and a theory is that a hypothesis is a testable statement, and a theory is a well-supported explanation. Thus, the correct option is A.

Which viral life cycle can be triggered to enter into the other one? What triggers that process?
Answer:
All viruses depend on cells for reproduction and metabolic processes. By themselves, viruses do not encode for all of the enzymes necessary for viral replication. But within a host cell, a virus can commandeer cellular machinery to produce more viral particles. Bacteriophages replicate only in the cytoplasm, since prokaryotic cells do not have a nucleus or organelles. In eukaryotic cells, most DNA viruses can replicate inside the nucleus, with an exception observed in the large DNA viruses, such as the poxviruses, that can replicate in the cytoplasm. RNA viruses that infect animal cells often replicate in the cytoplasm.
The Life Cycle of Viruses with Prokaryote Hosts
The life cycle of bacteriophages has been a good model for understanding how viruses affect the cells they infect, since similar processes have been observed for eukaryotic viruses, which can cause immediate death of the cell or establish a latent or chronic infection. Virulent phages typically lead to the death of the cell through cell lysis. Temperate phages, on the other hand, can become part of a host chromosome and are replicated with the cell genome until such time as they are induced to make newly assembled viruses, or progeny viruses.
The Lytic Cycle
During the lytic cycle of virulent phage, the bacteriophage takes over the cell, reproduces new phages, and destroys the cell. T-even phage is a good example of a well-characterized class of virulent phages. There are five stages in the bacteriophage lytic cycle (see Figure 1). Attachment is the first stage in the infection process in which the phage interacts with specific bacterial surface receptors (e.g., lipopolysaccharides and OmpC protein on host surfaces). Most phages have a narrow host range and may infect one species of bacteria or one strain within a species. This unique recognition can be exploited for targeted treatment of bacterial infection by phage therapy or for phage typing to identify unique bacterial subspecies or strains. The second stage of infection is entry or penetration. This occurs through contraction of the tail sheath, which acts like a hypodermic needle to inject the viral genome through the cell wall and membrane. The phage head and remaining components remain outside the bacteria.
This figure outlines the stages of the lytic cycle. Step 1 is attachment when the phage attaches to the surface of the host. The bacteriophage is shown sitting on the surface of the bacterial host cell. Step 2 is penetration when the viral DNA enters the host cell. The image shows DNA from within the virus being injected into the host DNA. Step 3 is biosynthesis when the phage DNA replicates and the phage proteins are made. The image shows various pieces of virus being built within the cell. Step 4 is maturation when the new phage particles are assembled. This shows the viral components being put together in the cell. The fifth step is lysis when the cell lyses and the newly made phages are released. This shows the cell bursting and built viruses being released.
Figure 1. A virulent phage shows only the lytic cycle pictured here. In the lytic cycle, the phage replicates and lyses the host cell.
The third stage of infection is biosynthesis of new viral components. After entering the host cell, the virus synthesizes virus-encoded endonucleases to degrade the bacterial chromosome. It then hijacks the host cell to replicate, transcribe, and translate the necessary viral components (capsomeres, sheath, base plates, tail fibers, and viral enzymes) for the assembly of new viruses. Polymerase genes are usually expressed early in the cycle, while capsid and tail proteins are expressed later. During the maturation phase, new virions are created. To liberate free phages, the bacterial cell wall is disrupted by phage proteins such as holin or lysozyme. The final stage is release. Mature viruses burst out of the host cell in a process called lysis and the progeny viruses are liberated into the environment to infect new cells.
Charles Darwin observed a unique beak size and shape in the finch population of each of the Galapagos Islands that he visited. 4 drawings of finch beaks. From left to right the beaks decrease in size. Which is the most likely cause of the observed variation? differences in the climate among the islands competition among individuals for available food sources competition among individuals for desirable mates differences in egg size among the populations
Natural selection would probably favor different varieties in the different islands. In other words, beaks changed as the birds developed different tastes for fruits, seeds, or insects picked from the ground or cacti (due to lack of food resources). Long, pointed beaks made some of them more fit for picking seeds out of cactus fruits.
