Answer:Each straight line segment represents a bond, the ends and intersections of the lines are carbon atoms, and the correct number of hydrogens is calculated from the tetravalency of carbon. Non-bonding valence shell electrons are omitted in these formulas.Each line represents a single covalent bond (two shared electrons), so double lines represent a double covalent bond (four shared electrons). Covalent bonds are usually found in atoms that have at least two, and usually less than seven, electrons in their outermost energy shell, but this is NOT a hard and fast rule.

Answer:

Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds. Just as the structure of the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions. To illustrate further, consider the two major types of chemical bonds: covalent bonds and ionic bonds. In covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail.

How would the toucan population be affected if the population of trees in its habitat decreased dramatically?
forsale [732]

The correct answer is B. Competition for food and shelter would increase, so the toucan population would decrease.

Explanation:

Birds such as toucans rely on trees to obtain food, shelter and a place to nest. Due to this, a decrease in the population of trees would cause food, shelter, etc. are limited, and therefore not all toucans can have access to it. This situation will lead to competition between toucans, and a decrease in the population of these birds. This decrease would be the result of toucans having fewer chances to survive and reproduce because food and shelter play an important role in these two aspects. According to these ideas, it is likely "competition for food and shelter would increase, so the toucan population would decrease".

A receptor can directly open a channel and thereby exert a(n) ____ effect, or it can produce slower but longer ____ effects.​
svlad2 [7]

Answer: ​ionotropic; metabotropic

Explanation:

A receptor can directly open the channel and exerts an ionotropic effect. The ionotropic effect takes place by the help of ionotropic receptors. These receptors are membrane bound receptor proteins which responds by the bonding of the ligand.

Due to ligand binding the channel opens and allows the movement of ions into the cells which helps in either increasing or decreasing the action potential.

The receptors can also bind to the ligand and produce metabotropic effect which means by the second messenger.
