When crude oil is distilled, it is separated into categories. What are those categories characterized by?
Answers
Answer:
Differences in their boiling points
Explanation:
When crude oil is distilled and separated into categories, the categories are characterized by the differences in their boiling points.
At different boiling points, each of the fraction will separate out.
Crude oil is made up of different fractions of hydrocarbons. As the chain length of the hydrocarbon increases, the volatility reduces and boiling point increases. Components with short carbon lengths rises out from the column first and are cooled and extracted. The categories are thereby, classified based on differences in their boiling points.in the mitosis of onion root experiment, why does the onion root have to be crushed into smaller pieces

Answers
Answer:
Answer
Explanation:
Sea breezes occur during hot, summer days because of the unequal heating rates of land and water. During the day, the land surface heats up faster than the water surface. Therefore, the air above the land is warmer than the air above the ocean.

Calvin cycle:
In Calvin cycle number of carbon atoms are constant in CO₂ and used to construct three-carbon sugars. This manner is fueled by, and established on, ATP and NADPH from the mild reactions.The Calvin cycle reactions occurs in three main stages: carbon fixation, reduction, and regeneration of the starting molecule.So, in the question it is asked how many G3P would be produced if there are 36 carbon dioxide that enters the Calvin cycle. Thus the answer is 12
In order for one G3P to go out the cycle (and move in the direction of glucose synthesis), 3 CO₂ molecules need to input the cycle, imparting 3 new atoms of constant carbon.

Jackson uses a battery operated toothbrush that is rechargeable. What happens when Jackson plugs his toothbrush into an electrical outlet to recharge it?
Answers
Answer:
Explanation:
The type of battery that Jackson's toothbrush is using is a secondary cell; this is because it can be recharged (meaning the electrochemical reactions taking place in the battery can be reversed). Batteries generally work in such a way that, while using it, electrons move from the anode of the battery to the cathode. In primary cells, this process continues until there are no electron to be transferred from the anode to the cathode and then the battery "dies" and is disposed. But in a secondary cell, just like the battery of Jackson's toothbrush, when the battery is been recharged, the electrons start moving from the cathode back to the anode; which makes electrons available again in the anode for use.

Answers
Answer:
melanopsin
Explanation:
this note might help you :
The retinohypothalamic tract (RHT) is a photic neural input pathway involved in the circadian rhythms of mammals. The origin of the retinohypothalamic tract is the intrinsically photosensitive retinal ganglion cells (ipRGC), which contain the photopigment melanopsin. The axons of the ipRGCs belonging to the retinohypothalamic tract project directly, monosynaptically, to the suprachiasmatic nuclei (SCN) via the optic nerve and the optic chiasm. The suprachiasmatic nuclei receive and interpret information on environmental light, dark and day length, important in the entrainment of the "body clock". They can coordinate peripheral "clocks" and direct the pineal gland to secrete the hormone melatonin.
information about melanopsin : Melanopsin is a type of photopigment belonging to a larger family of light-sensitive retinal proteins called opsins and encoded by the gene Opn4.[5] In the mammalian retina, there are two additional categories of opsins, both involved in the formation of visual images: rhodopsin and photopsin (types I, II, and III) in the rod and cone photoreceptor cells, respectively.

A
Glucose is transported into the cell by active transport
Subm
B
Nat is transported into the cell by active transport
с
The movement of glucose through the membrane requires ATP hydrolysis
D
Na transport out of the cell requires ATP hydrolysis
Answers
Answer:
The correct answer is - D . Na transport out of the cell requires ATP hydrolysis
Explanation:
Sodium-ion moves or transported from the inside of the cell to the outside the cell by the process called active transport. Active transport takes place takes place when the movement is against the concentration gradient to a higher concentration area through the cell membrane.
Active transport requires energy in order to transport the molecules or ions from low concentration to high concentration. In sodium-potassium pump get the energy from the hydrolysis of the ATP.
The given diagram represents the transport of sodium out of the cell using active transport. Active transport utilises the energy or ATP released during respiration. The correct answer is that sodium is transported out of the cell requires ATP.
Active transport is defined as the transport in which molecules move from lower to higher concentration, against the concentration gradient. The active transport requires the hydrolysis of energy to move across the cell. The sodium-potassium pump follows the active transport, such that:
The pumping of ions against the concentration gradient requires the addition of energy. The high-energy molecule is used to facilitate the active transport of sodium ions during the sodium-potassium pump.Therefore, the image represents the sodium is transported out of the cell by active transport.

Aerobic respiration has 3 stages: glycolysis, Kreb's cycle, electron transport
chain. What happens in each stage? How many ATP molecules made during
each stage?
Answers
What happens in each stage?
GLYCOLYSIS: "In glycolysis, glucose—a six-carbon sugar—undergoes a series of chemical transformations. In the end, it gets converted into two molecules of pyruvate, a three-carbon organic molecule. In these reactions, ATP is made, and NAD+ is converted to NADH." (Khan Academy)
KREB'S CYCLE: "This is a central driver of cellular respiration. It takes acetyl CoA—produced by the oxidation of pyruvate and originally derived from glucose—as its starting material and, in a series of redox reactions, harvests much of its bond energy in the form of NADH, FADH2, and ATP molecules. The reduced electron carriers—NADH and FADH2—generated in the TCA cycle will pass their electrons into the electron transport chain and, through oxidative phosphorylation, will generate most of the ATP produced in cellular respiration." (Khan Academy)
ELECTRON TRANSPORT: "In the electron transport chain, electrons are passed from one molecule to another, and energy released in these electron transfers is used to form an electrochemical gradient." (Khan Academy)
How many ATP molecules made during each stage?
GLYCOLYSIS: 2 ATP
KREB'S CYCLE: 2 ATP
ELECTRON TRANSPORT: 34 ATP
Khan academy is the best for breaking down processes in chemistry! I used khan all the time when I had trouble understanding chemistry last year.
Hope this helps! Please correct me if im wrong!
The word glycolysis initially means “glucose splitting,” which is exactly what happens in this stage. Enzymes split a molecule of glucose into two molecules of pyruvate (also known as pyruvic acid).
Stage 2 The Krebs Cycle
Recall that glycolysis produces two molecules of pyruvate (pyruvic acid). These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle. This cycle is at the center of cellular metabolism, playing a starring role in both the process of energy production and biosynthesis. It finishes the sugar-breaking job started in glycolysis and fuels the production of ATP in the process. It is also a central hub in biosynthetic reactions, providing intermediates that are used to build amino acids and other molecules. The citric acid cycle enzymes are found in all cells that use oxygen, and even in some cells that don't. The examples included here are taken from several different organisms.
Electron Transport Chain Stage.
The electron transport chain is a cluster of proteins that transfer electrons through a membrane within mitochondria to form a gradient of protons that drives the creation of adenosine triphosphate (ATP). ATP is used by the cell as the energy for metabolic processes for cellular functions.
