If a child is swinging back and forth on a swing. Changes in her kinetic and potential energy are happening each moment .
What is mechanical energy?The sum of all the energy in motion (total kinetic energy) and all the energy that is stored in the system (total potential energy) is known as mechanical energy .
As given in the problem a child is swinging back and forth on a swing. Changes in her kinetic and potential energy are happening each moment .
At the extreme end of the swing, the potential energy of the child is maximum and the at lowest height of the swing the kinetic energy of the child is maximum .

Through beta oxidation, fats are converted to acetyl CoAs. The further respiration of
these acetyl CoAs typically bypasses which parts of normal aerobic respiration?
Through beta oxidation, fats are converted to acetyl CoA. The further respiration of these acetyl CoA typically bypasses the glycolysis and pyruvate oxidation of normal aerobic respiration.
Glycolysis is the first process of respiration in which breakdown of glucose occurs. This process is common to both aerobic and anaerobic organisms and occurs on the cytoplasm of cells. One molecule of glucose is broken down to 2 pyruvates and a net gain of 2 ATP is observed.
Pyruvate oxidation is also called the linking reaction because it occurs to link the glycolysis and Krebs cycle. In pyruvate oxidation, pyruvate is oxidized to gain Acetyl CoA that further joins the Krebs cycle.

A graduate student injected 20 rats with a chemical compound commonly found as a pollutant in the environment and found that most of the rats developed tumors within a few weeks . Eager to publish her results the student comes to you , her advisor . What would you suggest the student do before trying to publish her results ?
The suggestion to the graduate student who injected rats with a chemical compound commonly found as a pollutant and found that most of the rats developed tumors within a few weeks should be: The student to conduct another experiment to ensure that the tumor development is because of the chemical.
Pollutants are the agents that pollute the environment. There can be pollutants causing air pollution, water pollution, soil pollution etc. The main pollutants are: particulate matter, plastic bags, chemical discharge waste from industries, etc.
Tumor is the mass of continuously dividing cells that may be benign or cancerous. If the tumor remains at one place it is benign, and if it shows the property of metastasis, it is cancerous.

In one of the reactions of the citric acid cycle, malate is oxidized to oxaloacetate. When this reaction is considered in isolation, a small amount of malate remains and is not oxidized. The best term to explain this is
When this reaction is considered in isolation, a small amount of malate remains and is not oxidized. The best term to explain this is entropy.
How does the citric acid cycle affect malate?Through the activity of NAD+-dependent malate dehydrogenase, malate is change to oxaloacetate, making the cycle to be full. In the Krebs cycle, there is the moving of electrons along with that of oxygen as the final acceptor.
Therefore, Entropy can be thought of as a rough point of the quality of energy, with lower entropy telling more about higher quality. Lower entropy energy is saved in an organized manner.

How does a lysosome go through autophagy? (what steps does it take)
Answer:
The completed autophagosome or amphisome fuses with a lysosome, which supplies acid hydrolases. The enzymes in the resulting compartment, an autolysosome, break down the inner membrane from the autophagosome and degrade the cargo. The resulting macromolecules are released and recycled in the cytosol.
2. Using the earliest microscopes, scientists were able to observeA. the structures inside a cell.B. molecules.C. tiny organisms and cells.
The first microscopes were optical microscopes, which means that the image was enlarged using lenses.
Antonie van Leeuwenhoek was able to observe single cells organisms, as well as red blood cells and spermatozoa, in the 1670s, with single-lens microscopes that were able to magnify the images 300 times.
This means C, tiny organisms and cells, is the right answer.
8. Which of the following genetic disorders occurs in individuals who arehomozygous recessive for that trait?A. Huntington’s diseaseB. AchondroplasiaC. Cystic fibrosis
As we know a recessesvie trait to be expressed the organism must be homozygous for the recessive allele, otherwise, it will be masked by the dominant allele, now Huntington's disease is a dominant disorder meanwhile, achondroplasia has an autosomal dominant pattern but does not follow a simple mendelian inheritance pattern, which left us cystic fibrosis, that is an inherited recessive disorder, therefore this is the correct answer (optionC).
type of Passive Transport #2 - OsmosisWater is SO important to cells, that the movement of water gets it's own name. Osmosis is the diffusionof water through a selectively permeable membrane from high concentration to low concentration. Justlike diffusion, it does not require energy (ATP) from the cell. Also like diffusion, when there is thesame concentration of water on both sides of a membrane, or there is the same concentration of water ina solution, the system has reached equilibrium. When water is in equilibrium, the water molecules stillmove, they just move at the same rate (speed).In the diagrams below, "W" represents a molecules of water and “S” represents a molecules of sugar. On eachdiagram below:1. Label each side of the rectangle HIGH for high WATER concentration and LOW forlow WATER concentration. If they are equal, write EQUAL.2. Draw an arrow to show which why the WATER molecules will move.Diagram ADiagram BDiagram CWS WS S SWSWWW WWSSS S WWW WWSSSSS SW WW WSWWWW SSS -WWWW WWWWWWWW W WWWWWWWSWSSW SWWWWWW WWWSSSSSSSS WWWWW3. Which diagram is in equilibrium for water?How did you know?4. The diagram below represents a laboratory setup used by a student during an investigation of diffusion.Distilled water is 100% water.Tube A-Glass tube-Tube BTubing10 mL ofdistilled water10 mL of watercontaining 5% starchDialysis membraneWhich statement best explains why the liquid in tube A will rise over a period of time?(1) The starch concentrations are equal on both sides of the membrane.(2) The water will pass from a region of lower starch concentration to one of higher starchconcentration.(3) Water and starch volumes are the same in both tubes A and B.(4) The fluids in both tubes A and B will change from a higher temperature to a lower temperature.In the diagram in #4, the starch will not move. Write a complete sentence explaining why.
In this case, we need to identify the diagram with water in equilibrium, which is diagram A, this is because the quantities of solvent (water) are the same on both sides if we count the number of W are 11 on each side, meanwhile, the sugar, number of S is similar, 5 on one side and 4 on the other, which indicates us that both solutions are similar, and so they are in equilibrium.
Annular and penumbral refer, respectively, to which phenomenon?
O A.
O B.
O C.
O D.
spring and autumn tides
solstice and equinoxes
solar and lunar eclipses
elliptical and round orbits
Annular and penumbral refer, respectively, to option C: solar and lunar eclipses.
What does an eclipse?A solar eclipse occurs when the Moon moves in front of the Sun, blocking some of the Sun's light on Earth either completely or partially. Because the Moon's orbit does not follow the same path as that of the Sun and Earth's, this only occurs on rare occasions.
Therefore, Penumbra is the lighter area, and umbra is the darker area. Penumbra implies partial shade, whereas "umbra" is similarly defined as shade.
