Generally, for fast-dividing mammalian cells, the length of the cycle is approximately 24 hours. G1 is typically the longest phase of the cell cycle. Cells usually remain in G1 for about 1o hours of the 24 hours of the cell cycle. Usually, cells will take between 5 to 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 to 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours.
From the given figure, mitosis takes 15 % of the 24 hours cell cycle. Plese see solution below:
24 hours x 15 / 100 = 3.6 hours

Which stage of cellular respiration produces the most energy for the cells
Answer:
the electron transport system - 3
Explanation:
Answer: The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS).
Explanation: The inner mitochondrial membrane holds the ATPase enzyme and the complexes for ETS. In mitochondria, an electrochemical gradient is produced by the function of ETS, between the matrix and inner mitochondrial space(High at internal mitochondrial space and low at matrix). ETS gets electrons from the oxidation of NADH and FADH2. The ATPase enzyme situated in the inner mitochondrial membrane allows protons to flow down their electrochemical gradient. This proton motive force is utilized for the phosphorylation of ADP into ATP. Thus, the production of ATP through ETS is called oxidative phosphorylation as oxidation and phosphorylation occur.

Which observation could lead to the conclusion that an object is nonliving?
A It passes on hereditary information only through asexual reproduction.
B It carries out synthesis.
C It cannot perform metabolic processes.
D It is composed of a cell, but does not have tissues.
The observation that will lead to the conclusion that an object is non-living is: (C) It cannot perform metabolic processes.
Non-living objects are those that do not follow the cell theory. These objects cannot perform the basic life processes like: respiration, digestion, breathing, growth, reproduction, etc. Non-living cannot show any movement on their own.
Metabolic processes are the various processes that are conducted inside the living body. These are of two types: anabolic processes and catabolic processes. Anabolic processes are those where larger molecules are formed from the smaller ones. While the catabolic processes are those where larger molecules are broken down to form smaller ones.

Explain why, in terms of photons, ultraviolet light can damage cells in your skin but visible light cannot.
Because UV waves are shorter than visible light waves, UV has more energy than regular light.
More importantly, UV photons have enough energy to damage or destroy DNA, whereas visible and infrared photons do not. When we absorb visible or infrared photons, the energy carried by the photon heats us up, but unlike ultraviolet photons, it does not permanently damage our cells.
The UV camera simply shows more melanin accumulation than we could see on our own, and the damage appears as a dark spot on the skin. Dry skin, which appears as a greenish glow or as bright green spots where the dry skin has flaked off, is also revealed by UV cameras.
Because UV waves are shorter than visible light waves, UV has more energy than regular light. UV photons have the necessary energies to cause chemical reactions.

Ohigh heat
O a lot of enzymes breaking down substrates
Odrastic change in pH
incorrect linking of amino acids (which changes the shape of the enzyme)
A lot of enzymes breaking down substrates does NOT slow down or stop an enzyme's rate of reaction.
By lowering the activation energy and consequently raising the rate of reaction, enzymes (and other catalysts) work. Since both directions must travel through the same transition state, the increased rate is the same in both the forward and reverse directions.An enzyme is a specific type of protein found inside of cells that catalyses chemical reactions necessary for maintaining life within the body. The important functions that enzymes perform are their purpose. These entail the development of muscles, the elimination of toxins, and the breakdown of food molecules during digestion.The biochemical modification of the enzyme—phosphorylation—or the use of positive modulators with low molecular weight can both speed up the activation of the enzyme. It is theoretically possible to bind molecules to enzymes to increase catalysis, just like with receptor agonists.To know more about enzymes check the below link:

Proteins are built from the RNA as the ribosome reads the instructions found in messenger RNA.
How are proteins constructed from RNA?Ribonucleic acid (RNA) is a nucleic acid found in all living cells that is structurally similar to DNA. RNA, unlike DNA, is typically single-stranded. Instead of the deoxyribose found in DNA, the backbone of an RNA molecule is made of alternating phosphate groups and the sugar ribose.
Ribonucleic acid is a polymeric molecule that plays important roles in gene coding, decoding, regulation, and expression. Nucleic acids include RNA and deoxyribonucleic acid. Transfer RNA (tRNA) is a type of RNA that assembles the protein one amino acid at a time.
Ribosomes synthesize proteins from ribosomal RNA (rRNA).

It has been proposed that human activities such as burning fossil fuels and deforestation affect global warming because they increase the concentration of greenhouse gases.
What are greenhouse gases?Greenhouse gases are different types of gases released to the atmosphere such as carbon dioxide or methane which produce a type of greenhouse effect by trapping the solar radiation into the earth's surface, which otherwise will be reflected into space.
It has been shown that such different greenhouse gases may affect the temperature of the earth by increasing several Celsius degrees since the industrial revolution, which was a point of break in the release of industrial gases such as carbon dioxide.
Therefore, with this data, we can see that greenhouse gases may be associated with human activities and therefore it has been proposed that this factor may increase global warming by producing a greenhouse effect.

What do you understand by the term viruses?A virus is a microscopic, contagious organism that can only grow inside of living cells. Virus infections are possible in all living organisms, include plants, animals, and microorganisms like bacteria and archaea. A virus is an infectious microorganism made up of a protein-coated segment containing nucleic acid (either DNA or RNA). A virus can't multiply by itself; it has to infect cells in order to utilise the host cell's components to produce copies of itself.

The physiological mechanism by which bleeding stops is known as hemostasis. Vasoconstriction, platelet plug development, and coagulation, in which clotting factors encourage the creation of a fibrin clot, are the three fundamental phases in hemostasis.
The process by which a clot is broken down in a healed vessel is known as fibrinolysis. Inhibitors of coagulation are known as anticoagulants. They have a critical role in reducing the intensity and duration of clotting.
Too few platelets or insufficient generation of clotting factors, such as in the genetic condition hemophilia, can both contribute to poor clotting. Excessive platelet production can result in thrombosis or excessive clotting.
