How does the Coriolis Effect cause hurricanes to form?
a
The Coriolis Effect causes the warm ocean waters to heat up.
b
The Coriolis Effect causes air masses to deflect, or curve. That deflected air can cause hurricanes to form.
c
The Coriolis Effect causes air to swirl upwards into the atmosphere.
Answer: b
Explanation: t affects weather patterns, it affects ocean currents, and it even affects air travel. As important as the Coriolis Effect is, many have not heard about it, and even fewer understand it. In simple terms, the Coriolis Effect makes things (like planes or currents of air) traveling long distances around the Earth appear to move at a curve as opposed to a straight line.
It’s a pretty weird phenomenon, but the cause is simple: Different parts of the Earth move at different speeds.

b

Which of the following is true with regard to sodium and potassium?
A
The both have three outer shell electrons.
B
They both have filled orbitals.
C
They tend to form anions.
D
They tend to form cations.
Sodium and potassium tend to form cations. Therefore, the correct option is option D among all the given options.
What is ions?An atom or molecule is said to be an ion if a number of the valence electrons have been acquired or lost, providing it a net negative or positive electrical charge. In other terms, a chemical species has an unbalanced ratio of protons (positive charge particles) to electrons (negatively charged particles).
Because there are more protons than electrons in a given species, cations are ions with a net positive charge. The equation for a cation is denoted by a superscript that includes the amount of the charge and the symbol "+" after the formula. If present, a number comes before the plus sign. If there is simply a "+" there, the fee is +1. Sodium and potassium tend to form cations.
Therefore, the correct option is option D.

A = Smooth Endoplasmic Reticulum
B = Vacuole
C = Mitochondria (Plural)
D = Nucleolus
E = Cell Wall
Explanation:
This is obviously a plant cell. Animal cells do not have cell walls(E), and most animal cells will not have a vacuole(B). Smooth Endoplasmic Reticulum: This produces protiens (contains ribosomes) but when looked through a microscope, will appear to be smooth. The vacuole(B) is like a storage for the plant cell, and it helps support the plant cell. This is the reason why plants “droop” when you don’t water them for a long time. Mitochondia (Plural) processes nutrients for the cell. The nucleolus(D) covers the nucleus. It’s main function is to process RNA and combine it with proteins. The cell wall(E) helps support and protect the cell.
