The major components of these fluids include water and solutes. The solute is mostly comprised of electrolytes: inorganic compounds that dissociate into ions. Electrolytes include cations (positively charged atoms – sodium, potassium, calcium, magnesium, carbonate) and anions (negatively charged atoms – chloride, sulphide, phosphate, bicarbonate).

Tin, because it has five energy levels with four electrons in the fifth level .

Explanation:

Tin has an electronic configuration as

1s2,2s2,2p6,3s2,...........4d10, 5s2,5p2

They have four valence electrons in their outer shell

Among the four diagrams given Tin is least reactive because the atomic radius of tin is largest among all four options. Due to large atomic radius electronegativity decreases and hence Tin is the least reactive element among Neon, Chlorine, gallium and tin.

The electronegativity of an element is its tendency to complete its octet by attracting electrons towards itself. Also tin is at the lowest place in the periodic table among all the four mentioned elements, its ionization energy is also low hence less electronegative and least reactive.

Which of these describes a situation where natural selection could lead to evolution?
Gennadij [26K]

Answer:

B. Predation removes slower antelope from the herd.

Explanation:

Natural selection is defined as the differential survival and reproduction of individuals due to differences in the physical characteristics.

A predator-prey relationship results in a very fast-slow dynamical system for rapid predator evolution.

Predation removes slower antelope from the herd and hinders passage of the slow trait to offsprings. The ones who are fast reproduce and give birth to other fast animals.

The youth movement originated with the ___ the generation born after ___
VLD [36.1K]
I believe that the youth movement originated with the baby boomers, the huge generation born after the world war II. By 1970, 58.2 % of the population in America was under the age of 35 years. The economic boom of the 1950s meant more families could afford to send their children to College. College life gave the young people a sense of freedom and independence. It was on college campuses across the nation that youth protest movements began and reached their peak.
