Chemiosmosis involves ions and these ions move through a membrane that allows ions to freely move through it. While the ions are moving they are moving down by means of the gradient. This gradient is the electrochemical gradient. ATP is one example of chemiosmosis because it involves hydrogen ions. These hydrogen ions move down the membrane and it takes place during photosynthesis when chloroplasts are changed to energy. When the chemiosmotic process is occurring in chloroplasts, it needs something in order for this to happen. This is the establishment of a proton gradient. The proton is also known as hydrogen ions which is how it can undergo this process. During this process, the proton moves from high concentration to low.

If the vagus nerve to the heart were to be cut, it would result in the heart rate speeding up by about 25 beats per minute, or answer B. It is called the vagus nerve, not the vagal nerve - although that is the name for stimulation of this nerve. This nerve is actually what helps the heart rate slow down, so cutting it means that the heart can’t slow down as much as it needs or wants to. This can be a dangerous thing. If a heart beats too fast, it will burn out. There’s a reason that people with higher resting heart rates often find themselves having cardiac arrest - their heart didn’t get the break it needed by lowering that resting heart rate through exercising.

Option B is correct. Accepting electron at the end of the electron transport chain is right. Oxygen is the last electron acceptor in the electron transport chain. Oxygen is not directly consumed in glycolysis, citric acid cycle, oxidation of pyruvate to acetylCoA or during phosphorylation of ADP. In the inner mitochondria membrane, electrons from NADH and FADH pass through the electron transport chain and this create an electrochemical gradient that is used by ATP synthase to generate ATP. Lastly, in the inner mitochondria membrane, electron is passed on to oxygen which is later reduced to water. Only the Electron transport chain consume ATP directly, every other cycle listed above do not consume oxygen directly.

ATP synthesis from ADP and a phosphate group occurs via a dehydration reaction and is the reverse process of ATP hydrolysis. She is ADP +P. Typically, this reaction happens in both directions, which means, that ATP breaks down into ADP, then ADP breaks down into ADP, then ADP rebuilds itself into ADP. This process is mostly dependent upon the addition and subtraction of a phosphate molecule and the energy required to bond to phosphate to ADP and release it from ATP. For ADP to form into ATP, energy is necessary as a catalyst to start the reaction. The release of energy as the three-strand phosphate bond of ATP is broken into two strands. This process commonly occurs with an ATP+H20 ADP +P. This reaction is known as hydrolysis. Hydrolysis has been utilized for a long time in the production of soap. ATP is the reaction by which hydrolysis occurs for ATP.

I didn't undestand the question and I thought it would be explained.

The answer is Tendons... B L o B - Bones - Ligaments - Bone B o T o M - Bone - Tendon - Muscle

DNA is the hard drive storing all of our information. During protein synthesis, the DNA is initially unfolded and then translated into a copy called the messenger RNA. It is this RNA that will actually be translated into the protein. The process is called transcription and translation. There is a special reason why RNA is used as a template for protein synthesis and not DNA. RNA as an expendable copy of the genetic material that the body can easily dispose of. While DNA is the hard copy and is better kept safe. Only unraveling when a section is needed to synthesize RNA for the manufacture of a specific protein.

How did you get that answer?

E is the answer to this question. It can always be a problem if there are chromosomes that fail to separate. This condition is also known as aneuploidy. This means that there is an abnormal number of chromosomes that are present in a cell. It is expected that chromosomes will always be even because they need to have a pair. It is easy to detect if there are certain conditions that a person is battling when there is an abnormal number of chromosomes that can be found in a cell. There are different types of aneuploidy that may occur depending on what has occurred or what has caused the condition.

Every single person has a number of beliefs and biases based on their values, experiences, and upbringing. We operate daily by reasoning through and believing in what we encounter based on those beliefs and biases and do so in an unconscious manner. This forms a filter through which we behave and make decisions. The media is comprised of a number of people, each of whom is making decisions about the facts that need to be reported and is using their own filter to do so. Simply because each person is essentially biased in some way, the reality isn’t truly represented factually. This is not done with malicious intent, it is human nature.

Option A - the proteins on its surface and that on the surface is correct. The protein in the host cytoplasm, whether its nucleic acid is DNA or RNA; the the enzymes carried by the virus and the enzymes produced by the virus before it infects the cell do not determine the host range of the virus. Host range is important in viral attachment, attachment of a virus is a specific binding between viral capsid (surface) proteins and specific receptors on the surface of the host. This specificity determines the host range of a virus.
