When you drop oil into cup of water, why does it hold together instead of breaking up in the water? Name at least three common substances which are examples of lipids that relate to the following areas of life: driving, eating, and your own body.

Answers

1. Oils are hydrophobic. Liquid water is held together by hydrogen bonds, and oils do not have a polar part, and it can not break hydrogen bonds, so it is forced to not dissolve in the water.

2. Three common substances which are examples of lipids that relate to driving is oil, one common substance of lipids that is related to eating is butter, and one substance of lipids that is related to your body are fats.

Thus, the correct options for this question are A, D, and E.

What is Mutagen?

Mutagen may be characterized as a type of agent that possesses the capability to induce mutation within the genetic segment of living organisms. Mutagens are of two types, they are:

Physical mutagens: UV radiations.Chemical mutagens: Chemicals like ethidium bromide.

According to the context of this question, mutation can only be inherited from parent to offspring, if it is induced within the gamete cells of parents. While during the course of life, the mutation also induces in the genomic sequence of an individual.

Therefore, the correct options for this question are A, D, and E.

Which description explains why there are two high and two low tides in a day? (4 points)

Earth moves closer to the sun and moon twice a day.

Earth revolves around the tidal bulges created by gravitational forces.

Earth rotates in and out of a tidal bulge twice a day.

The moon's gravity increases over the oceans and decreases over the land.

Answers

Answer:

Earth rotates in and out of a tidal bulge twice a day.

Earth always has two surrounding gravitational forces, one proceeding from the moon and one from the sun.

The sun's pull, despite the fact our sun is further then the moon, is stronger and creates the high tide, and the moon the low tide. But as we know our earth moves, now exposing the other side to the sun which in turn leaves the other side of earth with the high tides and the other with the low tides. Tides never move, what moves is earth.

Life on the MississippiMark Twain1 THERE was no use in arguing with a person like this. I promptly put such a strain on my memory that by and by even the shoal water and the countless crossing-marks began to stay with me. But the result was just the same. I never could more than get one knotty thing learned before another presented itself. Now I had often seen pilots gazing at the water and pretending to read it as if it were a book; but it was a book that told me nothing. A time came at last, however, when Mr. Bixby seemed to think me far enough advanced to bear a lesson on water-reading. So he began2 "Do you see that long slanting line on the face of the water? Now, that's a reef. Moreover, it's a bluff reef. There is a solid sand-bar under it that is nearly as straight up and down as the side of a house. There is plenty of water close up to it, but mighty little on top of it. If you were to hit it you would knock the boat's brains out. Do you see where the line fringes out at the upper end and begins to fade away?"3 "Yes, sir."4 "Well, that is a low place; that is the head of the reef. You can climb over there, and not hurt anything. Cross over, now, and follow along close under the reef--easy water there--not much current."5 I followed the reef along till I approached the fringed end. Then Mr. Bixby said--6 "Now get ready. Wait till I give the word. She won't want to mount the reef; a boat hates shoal water. Stand by--wait--WAIT--keep her well in hand. NOW cramp her down! Snatch her! snatch her!"7 He seized the other side of the wheel and helped to spin it around until it was hard down, and then we held it so. The boat resisted, and refused to answer for a while, and next she came surging to starboard, mounted the reef, and sent a long, angry ridge of water foaming away from her bows.Which BEST describes Mr. Bixby's influence on the narrator's learning how to "read" the water?Group of answer choicesA.) Mr. Bixby is an apathetic teacher, reluctantly instructing the narrator.B.) None of these represent an accurate description of Mr. Bixby and his teaching.C.)
