Which type of neuron is the fastest? Newsletter. 268 Speed (in miles per hour) at which signals travel along an alpha motor neuron in the spinal cord, the fastest such transmission in the human body. Sensory receptors in the skin, which lack the speed-boosting insulating layer called a myelin sheath, are among the slowest, at […]
How is the state of water determined?
How is the state of water determined? The number of bonds between molecules determines whether water will be a solid, liquid, or gas. In the solid state, water molecules have the maximum number of hydrogen bonds (4 per molecule), giving water the rigid characteristic of ice. What are three different states of water? Water can […]
Why Bubbles are not formed in water?
Why Bubbles are not formed in water? Atmospheric gases such as nitrogen and oxygen can dissolve in water. The amount of gas dissolved depends on the temperature of the water and the atmospheric pressure at the air/water interface. Hence bubbles along the insides of your water glass. Where do you think the bubbles came from? […]
What happens at an evidence hearing?
What happens at an evidence hearing? The preliminary hearing is like a mini-trial. The prosecution will call witnesses and introduce evidence, and the defense can cross-examine witnesses. If the judge concludes there is probable cause to believe the crime was committed by the defendant, a trial will soon be scheduled. How do you win a […]
Can sound waves bend?
Can sound waves bend? Sound waves do, indeed, bend. In an underwater thermal gradient the sonar waves can bend enough to create blind spots, so that you can not “see” a target that would ordinarily be well within sonar range. The other example is the difference in how well sound carries up/down wind. What is […]
What hormone raises blood sugar and increases the heartbeat and breathing rates?
What hormone raises blood sugar and increases the heartbeat and breathing rates? Adrenal-medulla Adrenaline Stimulates breakdown of glycogen to glucose, release of glucose into blood; increases rate of heartbeat and rate of respiration, Pancreas-islets of Langerhans Insulin Stimulates glucose oxidation and removal from bloodstream (storage). How do hormones in the endocrine system move around the […]
What is the two main function of a diode?
What is the two main function of a diode? Main functions The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking it in the opposite direction (the reverse direction). As such, the diode can be viewed as an electronic version […]
What is the primary output of the Calvin cycle?
What is the primary output of the Calvin cycle? Outputs of the Calvin cycle are ADP, P, and NADP+, which go into the light reactions, and sugar, which is used by the plant. 2. What is the most important result of photosynthesis? An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend. […]

Why is hydrogen placed in Group 1 and not 17?
Why is hydrogen placed in Group 1 and not 17? Hydrogen is placed above group in the periodic table because it has ns1 electron configuration like the alkali metals. However, it varies greatly from the alkali metals as it forms cations (H+) more reluctantly than the other alkali metals. Hydrogen has a much smaller electron […]
