Write a hypothesis about how the interaction of tectonic plates may cause earthquakes.
iVinArrow [24]

Answer:

hope this helps

Explanation:

Techtonic plates interacting with each other would cause an earthquake because they are essentially the earth's foundation so by sliding together they would  cause rockfall and make a rumble which is basically what an earthquake is and when they interact its basically the earth moving so it would cause shaking and rumbling which is what happens in an earthquake

(Additionally) in the aftermath of an earthquake the plates are either moving or settling down which is why frequently after an earthquake there is a mini one following it

Which of these conditions indicate positive feedback has occurred?
aleksklad [387]

Answer;

A) Blood pressure decreases greatly; blood flow to the heart is inadequate, and blood pressure decreases.

Explanation;

-With negative feedback, the output reduces the original effect of the stimulus. While in a positive feedback system, the output enhances the original stimulus.

-Negative feedback is the most commonly used feedback loop in the body. Negative feedback is used to negate or counteract a stimulus without completely eradicating it.

-One key difference between the two feedback is that positive feedback loops are used to eradicate a stimulus. Another key difference is that responses through positive feedback become more amplified over time. So once a stimulus activates a positive feedback loop it is not turned off until the stimulus is completely removed.

Which discovery supported the endosymbiotic theory?
alexdok [17]

The right answer is A.) DNA in mitochondria .

Eukaryotic cells, with their many intracellular organelles, have long been considered progeny of prokaryotes that would have become more complex as a result of genetic mutations. But from the 1960s, biologist Lynn Margulis proposed an alternative explanation that was first received coldly by the scientific community. His endosymbiotic theory, proposed in a more formal way in a 1981 book, proposes that eukaryotic cells as we know them today would be the result of a series of symbiotic associations with different prokaryotes.

Mitochondria and chloroplasts also have their own DNA that is not trapped in a nucleus, which is also the case with prokaryotes. However, the proteins encoded by this DNA do not cover all mitochondrial proteins. The prokaryote is thought to have lost some genes to the nucleus of the cell, a process known as "endosymbiotic gene transfer". For this reason, mitochondria and chloroplasts are now host-dependent for the synthesis of most of their components.
