What process is being used by the cell to move the molecules
The process that is being used by the cell to move the molecules is known as diffusion.
Diffusion is a method that has to do with the movement of substances within cells. It is also a method that's used for small molecules so that they'll be able to cross the cell membrane. It should be noted that the exchange of gas in the lungs of human beings operates through diffusion. For diffusion to take place, gaseous substances will have to go through the cell membrane in order to be able to go into a cell or out of the cell.Diffusion also takes place where there is a spread in particles. Diffusion is a movement from the region of a higher concentration to a low concentration.
In conclusion, the correct option is Diffusion.

What will happen if the DNA is not replicated?
O Mitosis will likely not occur.
Cytokinesis will occur before
mitosis.
O Mitosis will decrease the size of the cell.
O The number of chromosomes will reduce by half during mitosis.
Answer:
The cells within living organisms have the ability to grow and reproduce through the production of new cells. In order to ensure that an exact copy of the DNA is assigned to the new cells, a process called mitosis takes place. When a new cell is needed, the DNA is copied and allocated equally to new cells; then the cell splits in half. While mitosis is a precise system for distributing DNA, it is very complex and includes many cell components that must work in concert. When any one of these intricate steps fails, the results can be adverse for the cell and the whole organism.
During mitosis, a cell divides into two identical cells referred to as daughter cells. In order for both cells to be fully functional and to be able to mature, they each need a complete set of DNA. To prevent the mutations and errors in the DNA, the process has to be extremely accurate. Usually the error rate for copying DNA is around 1-3 errors for every billion base pairs. To get this extremely exact method of copying, there are many checks that happen within the process. The DNA helix unwinds and the strands separate to allow the enzymes used in replication to do their work. If the DNA strand is found to be broken or damaged, the entire process stops until it is repaired.
This process has to occur before mitosis because once mitosis starts, the cell is already preparing to divide. Soon after it begins, microtubules are forming in order to separate the newly replicated chromosomes. The DNA replication process not only has to be completed before this point, but the DNA has to be wound back up and the two copies of the same chromosome (now connected at a point in the chromosome) have to get in position so that they can be pulled apart, each destined for its new cell.

When do changes and
Interactions occur In The
Great Oxygenation event?
Answer:
Stage 1 (3.85–2.45 Ga): Practically no O2 in the atmosphere. ... Stage 2 (2.45–1.85 Ga): O2 produced, rising to values of 0.02 and 0.04 atm, but absorbed in oceans and seabed rock. Stage 3 (1.85–0.85 Ga): O2 starts to gas out of the oceans, but is absorbed by land surfaces. No significant change in oxygen level.

(HELP WANTED AUTOMATIC BRAINLY) Which statement describes how the muscular and skeletal systems cause parts of the body to move?
A. When a muscle relaxes, it causes a bone to shorten.
B. When a bone shortens, it lengthens the muscle attached to it.
C. When a bone bends, it pushes a muscle in the opposite direction.
D. When a muscle contracts, it pulls a bone in one direction.
Answer:
C.
Explanation: Because when a bone does bend the muscles pull back so the bone doesnt dislocate.
The statement describes how the muscular and skeletal systems cause parts of the body to move is when a muscle contracts, it pulls a bone in one direction.
What is skeletal system?The skeletal system is the in charge of all the bones and skeleton of the body. The skeletal system provides structure and strength to the body and protects the soft tissues.
The muscular system and the skeletal system work together as the muscles and bones are connected with each other.
Thus, the correct option is D. When a muscle contracts, it pulls a bone in one direction.

Which of the following is not a type of biological contamination?
A)bacteria
B)protozoa
C)viruses
D)herbicides
Herbicides are not a type of biological contamination since they are toxic substances that are not living things.
Biological contamination is the contamination by living microorganisms that are toxic. Herbicides are not the type of biological contamination. Thus, option D is correct.
What are biological contaminations?
The contamination of the food, water, air, or soil due to harmful living organisms is called biological contamination. These microbes cause diseases and illnesses in the other species.
Viruses, bacteria, and protozoans are the biological contaminants that result in diseases and pollution. On the other hand, herbicides are chemical substances that are used to kill the pests infesting the crops.
Therefore, herbicides are not biological contaminants.

describe one piece of evidence represented by the contour line on the map that indicates the north side of chimney bluffs is steep?
Incomplete question. Attached is the image of the map below.
Explanation:
From the map, we could notice the contour lines around the Chimney Bluff areas are closely packed together. In other words, the spacing between the contour lines is narrower than those found in other locations.
This assertion is accurate because it is a standard practice in many maps to indicate the steepness of an area by having the contour lines in close proximity.
3. A few years ago the population of male blue moon butterflies on the island of
Samoa declined. One hypothesis for the decline of the male butterflies is that a
parasite infected the cells of female butterflies. The parasite was passed to
offspring through the females' eggs and killed the male butterfly embryos. At
one point during the decline, nearly all the butterflies in the population were
females, but after five years the number of males in the population increased
significantly.
