Which of the following is true regarding lipids? *
1 point
Answer:
there are no answers, you can put them in the comments
Explanation:
The shape of each of the molecules is important because A) if the shape of any molecule in an organism changes, the DNA in that organism will also change B) the shape of a molecule determines the age of an organism C) the shape of a molecule determines how it functions in chemical reactions D) molecules having different shapes are always found in different organisms
Answer:
The correct answer would be - C) the shape of a molecule determines how it functions in chemical reactions
Explanation:
The molecular shape of the molecules is one of the important characters of the molecules. It is important due to the fact that molecular shape determines how a molecule will react and interact with other molecules.
The shape of the molecules determines boiling point, melting point as well as various chemical reaction by determining the bonds. For instance, H2O or water has a tetrahedral shape which affects its bonding and properties. If molecules were linear in shape there would be no life existed.
Thus, the correct answer would be - C)
Michael and Jose are studying about plate tectonics. They learned that plates usually move a few centimeters every year. They learned that the movement of heated material caused the plates to move. In which layer does the heated material move?
Answer:
Mantle layer
Explanation:
The movement of heated materials on the mantle layer of the earth helps in the movement of the tectonic plates. The earth is made up of four layers and they are the crust, the mantle, the outer core, and the inner core. The tectonic plates are always in motion which is very slow but constant.
The convection currents emanating from the mantle layer of the earth aids the movement of the tectonic plates. Natural disasters like earthquakes can result from the intense pressure emanating from the movement of the plates.
What is gained from each part of aerobic respiration?
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. ... This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

What is the relationship between Earths orbit around the sun and the force of gravity.
Answer:
Explanation:
the relationship is that if the sun stopped spinning, the earth would fly off into space and so the earth needs the suns gravity to keep us alive ^^
Answer:
the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

Why is it an important property for water to be less dense as a solid?
Answer:
Water has a unique density. It is less dense as a solid than it is as a liquid, which is why ice floats on top of liquid water.
Explanation:
Answer: Water’s lower density in its solid form is due to the way hydrogen bonds are oriented as it freezes: the water molecules are pushed farther apart compared to liquid water. With most other liquids, solidification when the temperature drops includes the lowering of kinetic energy between molecules, allowing them to pack even more tightly than in liquid form and giving the solid a greater density than the liquid.
The low density of ice, an anomaly, causes it to float at the surface of liquid water, such as an iceberg or the ice cubes in a glass of water. In lakes and ponds, ice forms on the surface of the water creating an insulating barrier that protects the animals and plant life in the pond from freezing. Without this layer of insulating ice, plants and animals living in the pond would freeze in the solid block of ice and could not survive. The detrimental effect of freezing on living organisms is caused by the expansion of ice relative to liquid water. The ice crystals that form upon freezing rupture the delicate membranes essential for the function of living cells, irreversibly damaging them. Cells can only survive freezing if the water in them is temporarily replaced by another liquid like glycerol.

n the northern United States where snow and ice create dangerous road conditions in the winter, the Department of Public Transportation often salt roads, which encourages melting. How could salting the roads have and impact on the plant life that live on the edge of the road?
Plant cells will lose water due to osmosis.
Plant cells will gain water due to osmosis.
Plant cells will use the salt to grow taller.
There would be no impact.
Answer:
Plant cells will lose water due to osmosis
Explanation:
Osmosis uses a concentration gradient. Water travels from areas of high concentration to low concentration. The salted road has low water concentration while the plants near the edge have a higher water concentration. The water will leave the plants and go to the salted road. Using common sense, if you sprinkle salt on a snail, it dehydrates and dies. Same thing happens here. The salt sucks the water out.

If Earth did not rotate and there were no Coriolis effect, surface wind
direction would primarily be *
From east to west
From west to east
From the poles to the equator
O From the equator to the poles
If Earth did not rotate and there was no Coriolis effect, the surface wind direction would primarily be from the poles to the equator.
What do you mean by the Coriolis effect?
The Coriolis effect may be defined as making things traveling long distances around the Earth appear to move at a curve as opposed to a straight line.
The Coriolis effect is responsible for the blowing of winds from the east to the west. It makes the wind system twist counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. Without its presence, the direction of wind gets opposed.
Therefore, if Earth did not rotate and there was no Coriolis effect, the surface wind direction would primarily be from the poles to the equator.

How reintroduction of the sea otter populations impacts the health of the kelp forest ecosystem describe the impact on at least 3 other l species within the kelp forest
Answer:
Sea otters encourage the growth of giant kelp forests as they control sea Urchin populations. Otters are a keystone predator. Kelp forests are curcial to many many many species of animals. Sea lions and seals feed on the fish there, many types of fish are found there crucial to fisherman such as all types of rock fish. Crabs, jelly fish, sea stars, anemones, and other small fish rely of these forests so it will greatly impact their population and over all health and the health of the ocean if there is a sea urchin population control.
