worm above, Moore records a length of 6.0 cm. Explain whether Moore's recording is accurate and why.
A)The earthworm length is shorter than 6.0 cm because the worm is curved.
B)The earthworm length is shorter than 6.0 cm because Moore used the
incorrect units.
C)The earthworm length is longer than 6.0 cm because the worm needs to
be straightened.
D)The earthworm measurement is accurate because Moore subtracted the
beginning and ending points from the ruler.
Answer:
C)The earthworm length is longer than 6.0 cm because the worm needs to
be straightened.
Explanation:
The choice is true because the image clearly illustrates that the earthworm is screwed into a part of its body. To make a proper measurement the earthworm must be fully stretched and measured from the head to the extreme tip of the "tail"
B. diatoms
C. green algae
D. euglenoids
E. amoeba
The answer is B. When diatoms die and fall off the ocean column to the ocean floor, they become part of sediments over time. When they are mined and exposed, they turn to a diatomite. Diatomaceous earth is significant as a pest repellant because of its hygroscopic property and has very abrasive particle hence it absorbs the water-protective fats and oils from the outermost layer of insects.
Answer:
B. diatoms

Earth rotates on an axis.
Earth revolves around the Sun.
The Moon rotates on an axis.
The Moon revolves around Earth.
Answer:
A
Explanation:
The Earth rotates on a tilted axis. Since the Earth also moves around the sun, one part of its face will be exposed the sun's light, while the other part will be in darkness.
Because the Earth spins, for a certain number of hours, one face will be exposed to the sun, so that's day. However, after spinning for a while, that face will then be turned away from the sun, and will experience darkness, which is night.
Thus, day and night are caused by the Earth's rotation on its axis.
Hope this helps!
Earth experiences day and night due to its rotation on its axis. When a part of Earth is facing the Sun, it experiences daylight while the part not facing the Sun experiences night. This is different from the Earth's revolution around the Sun, which causes the change of seasons.
The best description of why Earth has day and night is that the Earth rotates on its axis. Imagine the Earth as a spinning top. One full rotation or one complete spin of Earth on its axis is what we understand as a 24-hour day. When a part of the Earth is facing the Sun, it experiences daylight, and when it is not facing the Sun, it experiences night. It's this rotation that gives us the cycle of day and night. This rotation is fundamentally different from the Earth's revolve around the Sun, which takes about 365.24 days and gives us our year.

Cohesion is the term for molecules of a substance sticking together. One of the most common examples is water beading up on a hydrophobic surface. ... Because the water molecules' positive and negative charges are attracted to the positive and negative charges in the cellulose molecules in the paper.
