The following choices are provided;

One plate moves below the other due to the movements in the inner core.

One plate moves below the other due to the movements in the mantle.

A plate slides past another due to the movements in the inner core.

A plate slides past another due to the movements in the mantle

The answer is; One plate moves below the other due to the movements in the mantle.

It is common that such convergent boundaries have a cascade of volcanic ranges. This is because as the oceanic plate moves below the continental plate the pressure and high temperatures cause the rock to melt and become magma. The magma makes it way up the crust through fissure and erupts.

Meselson and Stahl used density labeling of DNA to show that DNA replication occurs via a semiconservative mechanism. In their e

cricket20 [7]

Answer:

The organism previously used 15N for replication so all the DNA molecules were of 15N15N type. Then the organism is shifted to a medium where only 14N is available for replication.
According to semi conservative mode of replication, a newly synthesised DNA molecule consists of one new strand and one parental strand. So after the first round of replication, All the 15N strands will synthesise new DNA strands using 14N resulting into intermediate 15N14N DNA molecules. Hence, only one band would be observed (15N14N) above the original 15N15N band since 15N14N has lighter isotope too so it will be lighter than 15N15N molecules and will lie above it.
After second round of replication, 15N strand from 15N14N would synthesise another 14N strand. 14N strand from 15N14N molecules will also synthesise another 14N strand. So now, 50% of the DNA molecules will be of 15N14N intermediate type and 50% of them will be of 14N14N type.Two bands will be observed above the original 15N15N band. One band of 15N14N molecules will be right above it and other band of 14N14N molecules will be even higher because it is the lightest band since it has only the lighter isotope of nitrogen.

<h2>Cannon -Bard theory</h2>

Explanation:

Alone in the woods, Pedro hears a noise. He thinks he sees a bear coming toward him. His heart starts pounding and then, a moment later, he realizes how frightened he is. This sequence of events is BEST explained by the <u>Cannon-Bard t</u>heory of emotion.

According to Cannon-Bard theory, all the emotional expressions occur due to the stimulation of hypothalamic structures present in brain. This theory also states that feeling and physiological effects of an emotional stimuli occurs simultaneously.

Here, James thinks that a bear is coming, this is a stimulus. His heart starts pounding that is the physiological effect of the stimulus and the next moment he feels frightened which is a feeling.

So we conclude that in this case, the physiological effect and feeling of emotion occurred simultaneously. So these sequence of events is best explained by Cannon-Bard's theory.

Why do clouds tend to form at 3pm and 6am

Verizon [17]

Clouds form as a result of the condensation of water vapor in the atmosphere. They are made of tiny droplets of water. Clouds tend to form between 3pm and 6pm because this is when the region starts to loose or has completely lost the heat form the daily sun. Water vapor will condense once temperatures are low or are decreasing.

Which most accurately describes the basis of the scientific method?

Tanzania [10]

The scientific method's foundation is best described as "the process of hypothesis and testing through which scientific inquiry happens." Thus, the correct option is D.

<h3>What is scientific method?</h3>

The scientific method is a set of actions that are followed in order to develop scientific knowledge.

The scientific process includes the following steps:

To make observations on a particular natural occurrence and then generate questions based on those observations.
To answer these questions, you must propose a credible explanation (i.e., a hypothesis).
To put the working hypothesis to the test using experimental and/or observational methods.
To gather information in order to confirm or refute a working theory.
Analyze the findings and develop conclusions.
