What causes a volcanic eruption?

Answers

Answer 1

When a part of the earth's upper mantle or lower crust melts, magma forms. ... Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber.

Answers

Answer: in 1925, people were sick and planes couldn’t land in nome, Alaska. Teams of dogs delivered the medicine

Explanation: I got it right on a quiz

In 1925, people were sick and planes couldn’t land in Nome, Alaska. Teams of dogs delivered the medicine has the most objective tone. Thus, the correct option is D.

What is the objective tone?

Objective tone is an impartial tone. This tone does not show any kind of feelings for or against a topic which therefore, is an unbiased or neutral feeling. The objective tone often uses higher level words and avoids pronouns such as I and you in the sentences, creating a type of formal tone. Subjective tone is a personal, biased, emotional, and often informal kind of tone.

Objective tone refers to an impersonal style of writing, which gives us the information about something however it does not include any information about the writer. So, a sentence like this: "In 1925, people were sick and planes couldn't land in Nome, Alaska. Teams of dogs delivered the medicine" is of the objective tone, Because it just tells us a fact.


Therefore, the correct option is D.

b) Identify a dependent variable in the experiments. Identify the reasoning of the scientists when they tested the number of colonies produced by strains C3-PBB and C6-PBB . The scientists also analyzed the number of colonies produced from each of the environmental and clinical isolate strains when the strains were plated on a growth medium lacking the toxic chemical. Justify this analysis.

Answers

A dependent variable is the number of colonies produced. The experiment gives a useful insight into the toxicity of the chemicals.

A scientific experiment must always have a dependent and an independent variable. A dependent variable is the variable whose outcome is being determined by manipulating the independent variable which in this case is the presence or absence of the chemicals.

Toxicity of chemical substances is a very important information to scientists as such this experiment is very important because it highlights the toxicity of the chemicals to living things.

If the pituitary is so important and Eric is not getting replacements of hormones the pituitary makes (except for ADH), why isn’t he dead? To answer this question, think through the cascade of events from hypothalamus to effect.

Answers

Answer:

The absence of ADH is not too dangerous.

Explanation:

If there is no place for the storage of ADH hormone in the pituitary hormones, no death occur of the individual because ADH is related to the conserve of fluid in the blood. If this hormone fails to perform its function properly, it causes the body to retain too much water. This more water retention may cause you to feel heavier than normal, and less active so the person did not die due to the deficiency of this disease.

A sports medicine major wants to conduct a experiment to determine if there there's a correlation between the members of the soccer team's leg strength and the time it takes for them to sprint 40 yards. He sets up the following test and records the data:

Every day for a week, he counts how many times each player can leg press 350 pounds. The following week, he has each player sprint 40 yards every day. The table shows the average number of leg-press repetitions and the average 40-yard dash time (in seconds) for seven randomly selected players. What is the equation of the line best fit? How many seconds should he expect a player to take to run 40 yards if that player can do 22 leg-press repetitions? Round any values to the nearest tenth, if necessary.
leg press (reps) 12 | 32 | 7 | 11 | 23 | 28 | 15 |
40-yard dash (s) 8.6 | 14.6 | 7.1 | 8.3 | 11.9 | 13.4 | 9.5 |

Answers

Answer:

The correct answer is the equation of the line of best fit is y=0.11x+4.54, and it would take the player 6.96 seconds to run.

Explanation:

Using technology, we calculate the line of best fit; we first enter the data points as a scatter plot, then run the regression tool, which gives us y=ax+b, where a=0.11 and b=4.54.

We now use this equation, y=0.11x+4.54, to calculate the amount of time it would take a player to run 40 yards if the player can do 22 leg-press reps:

y=0.11(22)+4.54=6.96.

B. A biodiverse ecosystem harbors many interactions, thus a  disturbance may impair some interactions, but not all.

Explanation:

Biodiversity is the variation of life forms in an environment. This is as a result of available nutrient and energy to support the various life forms.

The relationship between biodiversity and rebound from disturbance is such that a biodiverse ecosystem is able to resist any change. The disturbance might affect proportion of the populace. But on the long organisms can survived and be propagated again.

Cual de estos no se podria observar en un microscopio optico crestas mitocondriales, poros de la membrana nuclear, cromosomas de una celula animal condensados durante la mitosis, las dos capas lipidas que forman la membrana plasmatica

Answers

Answer:

Crestas mitocondriales, poros de la membrana nuclear y las capas lipídicas que forman la membrana plasmática no son visibles al microscopio óptico.

Explanation:

El límite de resolución de un microscopio óptico es de, aproximadamente, de 0,2 μm (es decir 10⁻⁶ m). Es decir, que en un microscopio óptico sólo podrán verse células y estructuras celulares mayores a 0,2 μm, y en algunos casos serán visibles sólo con tinciones especiales.

Por ende, entre las cuatro estructuras que se nos presentan en el problema sólo los cromosomas de una celula animal condensados durante la mitosis pueden verse al microscopio óptico.

Tanto las crestas mitocondriales como los poros de la membrana nuclear y las capas lipídicas que forman la membrana son estructuras muy pequeñas y visibles solamente al microscopio electrónico.

X-linked recessive disorder refers to the genetic condition in which mutations or errors are associated with the gene are present on the X chromosome. The male will be affected by the disorder, while the females can be carriers.

In the given Punnett square, there is a 25% chance that the offspring can be -red-green color blind.

Red-green color blindness in people refers to the difficulty in distinguishing the colors like red, green, orange, and yellow. People with color blind have a normal life and there is no proper cure for the condition.

Thus, the percentage of the offspring that will be red-green color blind is 25%.
