Define permafrost in you own words!
Answer:
Permafrost is ground that continuously remains below 0°C for two or more years, located on land or under the ocean. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface.
Explanation:
Answer: pick one
try this,
Permafrost is a permanently frozen layer on or under Earth's surface. It consists of soil, gravel, and sand, usually bound together by ice. ... Permafrost covers approximately 22.8 million square kilometers (about 8.8 million square miles) in Earth's Northern Hemisphere. Frozen ground is not always the same as permafrost.
or try this,
Permafrost is soil, rock or sediment that is frozen for more than two consecutive years. In areas not overlain by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the "active layer".

How does ATP structure relate to its function?
Answer:
The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups. ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups.

Compare and contrast the burning of a Cheeto with the cellular respiration that
happens in your body.
Answer:
Cellular respiration is similar to combustion because both reactions rely on fuel (reducing and oxidizing agents) to start the reaction; the difference is that in cellular respiration, enzymes are used during the reaction. Both result in smoke (CO2 and H20) and energy.

what are the two supporting evidence of seafloor spreading theory?
Answer: Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. This evidence led scientists to look again at Wegener's hypothesis of continental drift.

What is the relationship between genes DNA and proteins
Answer:
Although you might have heard people talk about a gene for red hair, green eyes or other characteristics, it's important to remember that genes code for proteins, not traits. While your genetic makeup does indeed determine physical traits like eye color, hair color and so forth, your genes affect these traits indirectly by way of the proteins created via DNA.
Hopefully, this answer helped! :D
Answer:
Most genes contain the information require to make proteins. The type of RNA that contains the information needed to make protein is called a messenger RNA or mRNA and it carries the message from the DNA out of the nucleus into the cytoplasm

list the symbol for lipids
Answer:
Carbon, Hydrogen and Oxygen. So the symbol is CHO.
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)

Explanation:
Meiosis I is often referred to as reduction division because it results in the reduction of the chromosome number from diploid to haploid. The chromosomes that remain in each cell are made of sister chromatids. During meiosis II, what will happen to the sister chromatids?
Answer: they will separate into different cells.
Explanation:
They separate into 4 cells.
Sister chromatids separate during meiosis II, resulting in haploid cells with non-duplicated chromosomes.
What is sister chromatid?A sister chromatid is two identical copies of a chromosome formed by DNA replication, with both copies joined together by a common centromere.
To put it another way, a sister chromatid is 'one-half' of a duplicated chromosome. A dyad is a pair of sister chromatids.
Meiosis II is analogous to mitosis. There is, however, no "S" phase. Because of recombination, the chromatids of each chromosome are no longer identical.
Meiosis II separates the chromatids, resulting in two daughter cells with 23 chromosomes (haploid), each with only one chromatid.
Thus, during meiosis II, there will be the separation of the sister chromatids.

In a car, how does an air bag minimize the force acting on a person during a collision? It increases the change in momentum of the person. It decreases the change in momentum of the person. It increases the time it takes for the person to stop. It decreases the time it takes for the person to stop.
Answer:
C
Explanation:
Just took the test and the answer is C, It increases the time it takes for the person to stop.
The air bag minimize the force acting on a person during a collision due to decreasing the time it takes for the person to stop.
How air bag minimize the effect of force during collision?Air bags are used in vehicles because they are able to minimize the effect of the force during a collision. Air bags minimize the effect by extending the time required to stop the momentum of the driver and passenger.
So we can conclude that air bag minimize the force acting on a person during a collision due to decreasing the time it takes for the person to stop.

What happens to the oxygen in respiration?
Explanation:
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

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.

Which of the following is an example of specific immunity?
Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.
