Answer:
Ratio = 9 : 2
Explanation:
We have been given two resistors, one with 2ohms rating and another with 4 ohms rating.
First they are connected in series. When resistors are connected into series, Equivalent resistance is given by:
Resistance (Equivalent) = R₁ + R₂ = 6 ohms
When these are connected in parallel, equivalent resistance becomes:
1 / Resistance (Equivalent) = 1/R₁ + 1/R₂ = 1/2 + 1/4
1 / Resistance (Equivalent) = 3/4
Resistance (Equivalent) = 4/3
Ratio = R(Series)/ R(Parallel)
Ratio = 6 : 4/3
Ratio = 18 : 4
Ratio = 9:2

Answer:
by introducing an invasive species it can drastically change the ecosystem. let's say you have the manatee, it has no natural predators, if you add an invasive species that eats manatees it may cause other things to start eating them too. this would cause the population to dwindle until there are few to none left because the invasive species population will go unchecked because nothing is accustom to eating them
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.
