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 […]
Which amino acid is involved in the formation of disulfide bonds?
Which amino acid is involved in the formation of disulfide bonds? The cysteine amino acid group is the only amino acid capable of forming disulfide bonds, and thus can only do so with other cysteine groups. What two functional groups are found in amino acids? Carboxyl and amino groups are always found in amino acids. […]
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 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 […]
Is magnetic energy a form of energy?
Is magnetic energy a form of energy? Each magnetic field contains energy, also called magnetic energy. She is a constant in physics. Because a magnetic field is generated by electric currents, the magnetic energy is an energy form of moving charge carriers (electrons). What kind of energy is magnetic energy? Moving a magnet around a […]
Is called autonomous unit of life?
Is called autonomous unit of life? The cell is known as the autonomous unit of life because it can independently carry out all the life activities necessary for its own survival. A cell has absolute independent existence. Why cell is called self-contained unit? The cell whether in a unicellular organism or a multicellular organism is […]
What is the most important muscle?
What is the most important muscle? The human heart is the most incredible muscle in the body, beating about 100,000 times to send 3,600 gallons of blood through 75,000 miles of blood vessels each day. Sure, skeletal muscles are vital to our ability to function, but the heart is truly a step above. What muscle […]
