Plasma contains more sodium than chloride. How can this be if individual ions of sodium and chloride exactly balance each other out, and plasma is electrically neutral?.
In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.
So this is how plasma is electrically neutral.
The makeup of bodily fluids:High levels of sodium, chloride, bicarbonate, and protein can be found in the plasma. High levels of salt, chloride, and bicarbonate but a relatively low level of protein can be found in the IF. The ICF, on the other hand, contains higher levels of protein, phosphate, magnesium, and potassium.What occurs when the plasma Na+ content rises?Although the plasma sodium concentration does not provide any information regarding the volume of extracellular fluid, it does allow for an assumption regarding intracellular volume. A rise in plasma sodium (plasma osmolality) causes water to be drawn out of the cell, which causes the intracellular volume to decrease.Why does plasma have a higher sodium content than chloride?In plasma, sodium predominates over chloride. In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.To learn more about plasma charge visit:

WBC count that can cause turbidity in the cyanmethemoglobin method resulting to falsely high hemoglobin value:_____.
A very high WBC count can lead to turbidity in the cyanmethemoglobin method resulting in falsely high hemoglobin value.
Cyanmethemoglobin method is a method which is used for the estimation of hemoglobin. In this method, hemoglobin is converted to cyanmethemoglobin by adding ferricyanide and potassium cyanide. The absorbance is then measured at 540nm using a spectrophotometer.
This is a very advantageous method as it is able to measure all forms of hemoglobin except sulphaemoglonin and also since spectrophotometer is used, subjective errors are avoided. But, if the WBC count is very high, it can lead to turbidity in the cyanmethemoglobin method resulting in falsely high hemoglobin value.

What event was khrushchev speaking of when he said the world had come close to ""destroying the human race""?
The Cuban missile crisis was the event Nikita Khrushchev was speaking of when he said the world had come close to "destroying the human race".
The Cuban Missile Crisis, also known as the October Crisis of 1962, the Caribbean Crisis or the Missile Scare, was a 35-day (16 October – 20 November 1962) confrontation between the United States and the Soviet Union, which escalated into an international crisis when American deployments of missiles in Italy and Turkey were matched by Soviet deployments of similar ballistic missiles in Cuba. Despite the short time frame, the Cuban Missile Crisis remains a defining moment in US national security and nuclear war preparation. The confrontation is often considered the closest the Cold War came to escalating into a full-scale nuclear war.
In response to the presence of American Jupiter ballistic missiles in Italy and Turkey, and the failed Bay of Pigs Invasion of 1961, Soviet First Secretary Nikita Khrushchev agreed to Cuba's request to place nuclear missiles on the island to deter a future invasion. An agreement was reached during a secret meeting between Khrushchev and Cuban Prime Minister Fidel Castro in July 1962, and construction of a number of missile launch facilities started later that summer.
The missiles in Cuba allowed the Soviets to effectively target most of the Continental US. The planned arsenal was forty launchers. The Cuban populace readily noticed the arrival and deployment of the missiles and hundreds of reports reached Miami. US intelligence received countless reports, many of dubious quality or even laughable, most of which could be dismissed as describing defensive missiles.
Only five reports bothered the analysts. They described large trucks passing through towns at night that were carrying very long canvas-covered cylindrical objects that could not make turns through towns without backing up and maneuvering. Defensive missile transporters, it was believed, could make such turns without undue difficulty. The reports could not be satisfactorily dismissed.

If it were possible to have antagonistic muscle pairs in an arm contract simultaneously, what movement would the arm make?
If it were possible to have antagonistic muscle pairs in an arms contract simultaneously, the arm would be locked in position.
How do antagonistic muscle pairs work?
Tendons allow muscles to exert force on bones. They pull on our bones and related body parts to move them; this activity is referred to as muscle contraction. In "antagonistic muscle pairs," muscles function. A pair of muscles work together to move a body part, and then the other muscle in the pair works together to bring the body part back to its starting position.
Antagonizing pairs of muscles are those that function in this way. When two muscles are antagonistic, one contracts while the other relaxes or lengthens. The muscle that is lengthening or relaxing is referred to as the antagonist, while the muscle that is contracting is referred to as the agonist.

Potassium-Argon Dating
Uranium-238-Lead-206 Dating
Carbon-14 Dating
The isotopes in order from longest half-life (3) to shortest half-life are Uranium-238-Lead-206 Dating, Carbon-14 Dating, and Potassium-Argon Dating.
Isotopes are two or more different atom types that share the same atomic number and are placed in the periodic table but have different quantities of neutrons in their nuclei, resulting in various nucleon numbers.
The duration needed for a quantity of a radioisotope to decay by half is known as its radioactive half-life. The majority of the radioactivity will disappear within a few days if an isotope has a half-life of only a few hours or less.
Uranium-238 decays to lead-206 and uranium-235 decays to lead-207 in uranium-lead dating. While carbon-14 has a half-life of only 5,730 years, uranium-lead dating can be used to date rocks that are billions of years old.
The half-life of carbon-14 is 5,730 40 years, meaning that for the next 5,730 years, half of the radioisotope that is present at any particular time will spontaneously disintegrate.
Potassium-40's half-life is 1.3 billion years, far longer than carbon-14's, making it possible to date even older samples. Due to the prevalence of potassium in rocks and minerals, it is possible to date several samples with geochronological or archaeological value.
