Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.
The answer is false. Spider bodies are made up of two segments and they have eight legs. Insects have three segments and a varying number of legs based on the species. As a predator, spiders also have multiple eyes, while insects have only two, however they may be able to rotate or otherwise be able to get a full view of their surroundings in that fashion.
Venter pioneered the use of automated gene sequencers, and in 1990, he developed “expressed sequence tags” (ESTs), a new strategy for the discovery and tagging of genes that revolutionized biological science.
<h3>
Answer: sec(B), third choice</h3>
Recall that csc, which stands for cosecant, is defined as follows
csc(x) = 1/( sin(x) )
it is the reciprocal of the sine function. Multiplying csc(B) and sin(B) together yields 1. This result multiplies with the only thing left, sec(B), to get the final answer.
