The star in the diagram represents which of these? A. origin of replication B. replication fork C. replication bubble D. Okazaki fragment
Given what we know about the process of DNA replication, we can confirm that the star shown in the diagram represents the replication fork.
During the replication of DNA in the cellular process of multiplication, a structure known as the replication fork is formed. This fork is a structure that forms by helicases, which tear the hydrogen bonds that hold together two DNA strands in the form of a double helix.
The resulting structure contains two prongs, which are branches of the original DNA strand which are no longer doble or in the form of a helix. This area where the strands are separating into prongs is the replication fork which is being marked in the diagram by the star.

Write a sentence that relates your model to processes that take place inside your own cells. Your answer should include some form of the terms mitosis, nucleus, and cell division.
Answer: Cell division or mitosis is a nuclear cell division that results to two daughter cells having the same genetic code as the parent cell. The division starts at the nucleus. The chromosomes divide into two and a spindle is formed at middle of the cell. The spindle shortens and breaks resulting to two daughter cells.

Aldosterone ____________ ion exchange at the distal convoluted tubule. This helps to regulate the reabsorption of sodium and water
Aldosterone, the main mineralocorticoid steroid hormone ion exchange at the distal convoluted tubule.
This helps to regulate the reabsorption of sodium and water.
Discussion;
To prevent osmolarity from decreasing below normal, the kidneys also have a regulated mechanism for reabsorbing sodium in the distal nephron.
The mechanism in discuss is controlled by aldosterone, a steroid hormone produced by the adrenal cortex.

In the bacterial CRISPR system, the crRNA performs which of the following functions?
The CRISPR-Cas system is a genome engineering tool to edit the genome of any species. The crRNA is a sequence complementary to the target DNA of this genome editing system.
The CRISPR-Cas genome editing system is a recently developed genome engineering tool, which can be used to edit the genome of virtually any species.
This genome editing system consists of a nuclease (Cas) protein that cuts the DNA at the targeted regions, and a single guide RNA (sgRNA), which contains a crRNA (17-20 nt) sequence complementary to the target DNA.
In consequence, the sgRNA guides to the Cas protein in order to cleave the genome at targeted nucleotide sequences.

The sequence by which electrons travel downhill during aerobic respiration. The se sequence has NADH, oxygen chain of transportation of electron, food and NAD.
Respiration (both aerobic and anaerobic) begins with glycolysis in the cytoplasm of a cell;
1 glucose molecule (C₆H₁₂O₆) is converted into 2 molecules of pyruvate in a 10-step process, consuming 2 ATPs and yielding 4 ATPs;
Additionally, 2 NAD+ molecules are reduced to NADH molecules;
In aerobic respiration, each pyruvate molecule then goes through the link reaction, getting converted to acetyl co-A in the mitochondrial matrix, producing 1 CO₂ molecule and 1 reduced NADH molecule;
Acetyl co-A then enter the Krebs or tricarboxylic acid cycle (TCA) where 2 CO₂, 1 ATP, 3 NADH (by reduction of NAD+) and 1 FADH₂ molecules are produced;
The NADH and FADH₂ molecules produced are electron carriers required for the electron transport chain (ETC);
The electron transport chain consists of 4 proteins within the inner mitochondrial membrane which are involved in the production of ATP by oxidative phosphorylation;
The first protein (C1) is responsible for oxidising NADH to NAD+, releasing energy used to generate the proton motive force (PMF) by pumping the protons (H+ ions) into the intermembrane space and the electrons released are transferred to a ubiquinone molecule;
The second protein (C2) is responsible for oxidising FADH₂ to FADH, also releasing energy used to generate the proton motive force (PMF) and, similarly to C1, the electrons released are transferred to ubiquinone;
The third protein complex (C3) transfers the electrons from ubiquinone to cytochrome C;
Finally, cytochrome C transfers these electrons to the fourth complex (C4), where they combine with free protons in the matrix and O₂ to to produce H₂0;
The PMF is then harvested via an ATP synthase protein where H+ flood back into the mitochondrial matrix, and the energy released is used to generate ATP from ADP and Pi;
ATP is now ready for use for bodily processes requiring it.
How is the small intestine adapted to its function?
Answer:
The enzymes in the small intestine, help break the food up into smaller particles. Those tiny particles are then absorbed through the thin lining of the intestine into the bloodstream and are carried all where they are needed in the body. Therefore making it adapted to it's function, which is breaking down food including carbohdrates, fats and proteins :>

The Process of Cellular Respiration
Cellular respiration is the process of extracting energy in the form of ATP from the glucose in the food you eat. How does cellular respiration happen inside of the cell? Cellular respiration is a three step process. Briefly:
In stage one, glucose is broken down in the cytoplasm of the cell in a process called glycolysis.
In stage two, the pyruvate molecules are transported into the mitochondria. The mitochondria are the organelles known as the energy "powerhouses" of the cells (Figure below). In the mitochondria, the pyruvate, which have been converted into a 2-carbon molecule, enter the Krebs cycle. Notice that mitochondria have an inner membrane with many folds, called cristae. These cristae greatly increase the membrane surface area where many of the cellular respiration reactions take place.
In stage three, the energy in the energy carriers enters an electron transport chain. During this step, this energy is used to produce ATP.
Oxygen is needed to help the process of turning glucose into ATP. The initial step releases just two molecules of ATP for each glucose. The later steps release much more ATP.
The process is of cellular respiration. Cellular respiration is the process through which the glucose in the food you eat is converted into ATP, which is then converted into energy.
What is cellular respiration?
In the first stage, a procedure known as glycolysis breaks down glucose in the cell's cytoplasm.
The pyruvate molecules are delivered to the mitochondria in stage two. The organelles known as the cellular "powerhouses" of energy are called mitochondria
Pyruvate enters the Krebs cycle in the mitochondria after being transformed into a 2-carbon molecule. These cristae significantly expand the area of the membrane where most cellular respiration occurs.
Therefore, The process is of cellular respiration. Cellular respiration is the process through which the glucose in the food you eat is converted into ATP, which is then converted into energy.
