Cell division is necessary for many life roles. It is needed for prokaryotes and single-celled eukaryotes to reproduce. Multicellular eukaryotes require cell division to develop from embryos into full-grown organisms. Those organisms then need further cell division for processes like growth, cell renewal, and damage repair. Describe the phases of the cell cycle, including the mitotic phases. Provide at least one major characteristic of each phase.
Answer:
The mitotic phases alternate with interphase in the cell cycle. In interphase, the G1 phase occurs first where the cell grows while carrying out cell functions unique to its cell type. Then the S phase takes place where the cell duplicates its chromosomes. Next is the G2 phase, just before mitosis where the cell continues to grow and carry out its functions. After interphase, mitosis occurs, the first phase in mitosis is prophase where the chromatin becomes tightly coiled and the nucleoli disappear. Next is prometaphase where the nuclear envelope begins to fragment, and the two chromatids of each chromosome are held together by the centromere. After prometaphase is metaphase during which the microtubules and move the chromosomes to the metaphase plate at the equator of the cell. Next is anaphase where the sister chromatids separate. After anaphase, telophase occurs where the nuclear envelopes reform around the set of chromosomes located at opposite ends of the cell. Cytokinesis also occurs which is the division of the cytoplasm.

How did you save Clark?
The following list is not in the correct order. The first two events are given to you as a starting point. Drag and drop the remaining events to identify the sequence of events showing how hypertonic saline restored equilibrium and stopped the seizures in Clark's brain.
Seizures
1.
2.
Administer hypertonic saline
Answer:
Since there are only two options listed and not much else, the correct order would be: first, the seizure happens and then you administer the hypertonic saline solution in order to stop the seizure and restore the correct balance.
Explanation:
This question comes from a more complete case where Clark suffers from cerebral edema due to an abnormal level of sodium (Na) which caused water imbalance to happen.
It must be remembered that the human brain works under a balance of water and electrolytes. One of which is sodium. In essence, where sodium goes, water goes. When sodium is in too low concentrations somewhere, the tendency is for the stores to go out to restore balance. Water will follow sodium as well.
In the case of Clark, because sodium was too high inside the tissues, then water leaked into those tissues to restore balance, causing the pressure around the brain to increase. Thus, as a form of protection, the brain seizes and shuts until the balance is restored. The hypertonic solution administered after the seizures has the purpose of increasing sodium in the blood so that water will move out of the tissues and back into the bloodstream.
This is why the correct order with the elements given by the question is 1. Seizures and 2. Administer hypertonic saline solution.
Answer:
3. Increase in blood sodium concentration
4. Net movement of free water into vessel
5. Decrease in matrix pressure
6. Decrease in neuron firing rate
7. Seizures stopped

Some snakes are able to detect infrared light using photoreceptors. These photoreceptors are located in their pit organs, not in their eyes. Why is this still considered "sight"?
Because these photoreceptors are also present in their eyes.
Because the photoreceptors connect to the gustatory region of the brain.
Because all detection of light is considered sight.
Because the photoreceptors connect to the visual areas of the brain.
Answer:
Because the photoreceptors connect to the visual areas of the brain.
The photoreceptors of the snake are still considered "sight" because they connect to the visual areas of the brain. Thus, the correct option is D.
What are Photoreceptors?Photoreceptors may be defined as the types of cells which are present in the retina and have the ability to respond to light.
In snakes, photoreceptors are not present in their eyes but still able to detect infrared light, this indicates that the photoreceptors have a direct connection with the visual areas of the brain which stimulates the sense of perception toward the light.
Therefore, the correct option for this question is D.

Yeast, a single-celled organism, uses cellular respiration in order to produce ATP. What is a byproduct made during respiration for yeast? 1. C6H12O6 2. CO2 3. Oxygen 4. Fructose
Answer:
Byproduct: option 2 (CO2)
Option 2. CO2.
In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.
What is cellular respiration?Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which can then be used as energy to power a variety of reactions throughout the body. Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.Adenosine triphosphate (ATP) is the cellular energy source for use and storage. ATP is a nucleoside triphosphate with the structure of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.To learn more about : Cellular respiration

Make two fists and place them together so your knuckles are touching each other. Slide one hand toward you and the other hand away from you so your knuckles rub together. What happens? What might happen to two tectonic plates as they move this way?
Answer:
The knuckles are like a jagged surface. When they rub together, they act as obstacles to each other. It’s difficult to move the hands freely as the knuckles catch and release one another. In the case of tectonic plates, if two plates rub, they release large amounts of energy, which can cause earthquakes.
