You see a worm crawling along the ground and wonder if scientists consider it living or nonliving. Which item below would not be true when classifying the worm as living or non‐living?
A worm can move so it must be living.
A worm can reproduce and make little baby worms (called wormlets) so it must be alive.
Worm’s pass dirt through their body pulling food out and discarding the stuff they don’t want so it must be alive.
If you cut a worm in half, it can re‐grow so it must be alive.
Answer: a. A worm can move so it must be living.
Explanation:
If a worm is moving it is classified as a moving worm also known to be living if moving.
A worm could reproduce therefore it is living.
Worms do pass dirt into and through there bodies to eat of the minerals and discarding things through and let out.

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.

Explanation:
If you have a parallel circuit with a battery (4 ohms), a light bulb (2 ohm), and a fan (3 ohms), how would you find the total resistance of the circuit?
Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +...
Answer:
resistance = 0.9230769230769231
Explanation:
The total resistance can be found by using the following equation:
1 / R = 1 / R1 + 1 / R2 + 1 / R3
