What is the difference between a mouth ulcer and a canker sore?
A mouth ulcer is a general term for any sore or lesion in the mouth, while a canker sore specifically refers to a type of mouth ulcer that is not caused by a virus.
What is the term for any sound that is too high for humans to hear?
The term for any sound that is too high for humans to hear is "ultrasonic."
What is the difference between arrhythmia and atrial fibrillation (AFib)?
Arrhythmia is a general term for any irregular heartbeat, while atrial fibrillation (AFib) is a specific type of arrhythmia where the heart's upper chambers beat irregularly and too fast.
The term for any organisim with only onc cell is?
The term for any organism with only one cell is called a unicellular organism.
What is the charge of a Peptide with sequence aggdrleeq at pH 7.0?
At a neutral pH i.e. pH 7, only five of the twenty common amino acids carry a net positive or a net negative charge. Aspartic acid and Glutamic acid are negatively charged (-1), at a neutral pH the carboxlic side chains lose a H+ ion Lysine, Arginine and Histidine are positively charged (+1), at a neutral pH the side chains accept a H+ ion. All other amino acids are generally uncharged (0). It is therefore easy to work out the net charge of any sequence. All sequences contain the one letter abbreviation for each amino acid. Here the sequence is "aggdrleeq" a=alanine (uncharged = 0) g=glycine (uncharged = 0) g=glycine (uncharged = 0) d=aspartic acid (negatively charged = -1) r=arginine (positively charged = +1) l=leucine (uncharged = 0) e=glutamic acid (charged = -1) e=glutamic acid (charged = -1) q=glutamine (uncharged = 0) Add up all the charges -3, +1 gives a total peptide charge of -2.
Which term describes the particle that results when an electron is added to an atom?
It depends. If you are talking about electron capture at the molecular level, then when a neutral atom (or molecule) absorbs a negatively charged electron, it becomes negatively charged. All charged atoms (or molecules) are called ions, and a negatively charged ion is called an anion. . If, on the other hand, you are talking about electron capture by the nucleus of an atom, then when a positively charged proton absorbs a negatively charged electron, the proton converts into a neutrally charged neutron and immediately emits a neutrally charged electron neutrino.
2.Positively charged objects can only attract objects that are negatively charged?
Any charged object weather positively charged or negatively charged will have an attractive interaction with a neutral object. Neutral objects do not attract or repel each other.
Is DNA charged in any way?
Yes, DNA is charged because it contains negatively charged phosphate groups in its structure.
What is something with a negatively charged particle?
Things that contain negatively charged particles include atoms, protons, neutrons, as well as any molecules, and larger, everyday, objects.
Is solute molecule negatively charged in water?
Not necessarily. Solute molecules can be neutral, positively charged, or negatively charged in water. The charge of the solute molecule depends on its chemical structure and the presence of any functional groups that can interact with water molecules.
When a glass rod and fur rubbed together electrons are transferred from the fur to rod. Is the fur charged If any positively or negatively charged How much compared to the rod?
Yes, the fur becomes negatively charged as it loses electrons to the glass rod. The glass rod becomes positively charged as it gains these electrons. The fur is negatively charged compared to the rod.
Is carbon postively charged?
No. Any element on its own is neutral, meaning it does not have a charge. Carbon rarely forms ions, and when it does they are negatively charged.
Is hydrogen neutrally charged?
Yes. Any element on its own will be electrically neutral. However, "neutrally charged" is something of an oxymoron as the term "neutral" means that there is no net charge.
What is a negatively charged matter?
Any material can be charged, either positively or negatively. It has no name as such. You can do that by shuffling your feet back and forth on a carpet and touching something. You can feel a spark from your finger. By shuffling your feet your body acquires a charge, which discharges when you touch a metal object that is grounded.
When an object is charged by rubbing how to identify whether the charge of the object is positive or negative?
An object that gains electrons during rubbing will become negatively charged, while an object that loses electrons will become positively charged. This is based on the principle that electrons are negatively charged particles.
What carry a what electrical charge?
Electrons are negatively charged. (The positron is a positively charged version). Protons are positively charged, so an anti-proton would carry a negative charge. Any object that has, on average surplus electrons in the outer-shells of electron orbitals will appear negatively charged.
What is cation and anion?
Cations are positively charged ions. Anions are negatively charged ions. An ion is just an atom with either more electrons than protons (so it would be negatively charged... an anion), or fewer electrons than protons (so it would be positively charged... a cation). It should be noted that not all ions are single atoms. You can have polyatomic (many atom) anions (like SO42-) or cations (like NH4+). These are just molecular compounds that have charge because they have gained or lost electrons.
