Answer: Chloroplast
Explanation: Chloroplasts work to convert the Sun's light energy into sugars that cells can use. It's like a solar panel that converts energy from sunlight into electric power.

Explanation:
Why does the Moon appear red during a lunar eclipse?
1.)Because the sunlight bends as it passes through the Earth's atmosphere
2.)Because the sunlight bends as it passes through the Moon's atmosphere
Answer:
Image result for Why does the Moon appear red during a lunar eclipse?
A lunar eclipse takes place when the sun, Earth and moon line up in space. The moon passes through Earth's shadow. ... Bottom line: The moon can look red during a total lunar eclipse because of sunlight that's filtered and refracted by Earth's atmosphere
Why is it important for body cell to have twice and many chromosomes as sex cells?
Answer:
Why sex cells only need half the number of chromosomes compared to other cells in the body? As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.

What patterns occur in the Earth-Sun-Moon system that allow us to identify the cause of
eclipses?
Answer:
Earth's rotation and orbit and the Moon's orbit cause observable patterns (Day and night, seasons, phases of the Moon, tides).
TRUE OR FALSE
1. TRUE OR FALSE: The higher the frequency, the closer the waves are together and the LOWER the energy carried by the waves will be.
2. TRUE OR FALSE: The greater the force that produces a wave, the greater the amplitude of the wave and the greater the energy carried by the wave.
3. TRUE OR FALSE: In a transverse wave the higher the wave, the LOWER the amplitude
4. Wavelength is a measure of the distance from the crest on one wave to the crest on the very next wave.
5. TRUE OR FALSE: Speed is a measure of the distance a wave travels in an amount of time
6. TRUE OR FALSE: As a wave enters a different medium, the wave’s speed changes. Waves travel at different speeds in different media
7. TRUE OR FALSE: The highest point of a transverse wave is the crest and the lowest point is called a trough.

7. The highest point of a transverse wave is the crest and the lowest point is called a trough. TRUE
What is Wave ?A wave is a disturbance in a medium that carries energy and as well as momentum. Energy can be transferred in the form of wave in the medium. there are two types of wave,
longitudinal wave : in which, vibration of the medium (particle) is parallel to propagation of the wave as shown in the fig.1. Sound wave is a longitudinal wave.
Transverse wave : in which, vibration of the medium (particle) is perpendicular to propagation of the wave as shown in the fig.2. Light wave is a longitudinal wave.
1. E = hυ where υ is a frequency which shows direct relation between Energy E and frequency υ. Hence it is false.
2. True
3. In a transverse wave the higher the crest in the wave, the higher the amplitude. FALSE
4. True
5. True, Speed = Distance÷Time
6. due to change in refractive index, velocity changes TRUE
7.True

A wave has a period of 2 seconds and a wavelength of 4 meters. Calculate its frequency and speed.
Note: Recall that the frequency of a wave equals 1/period & the period of a wave equals 1/frequency.
Answer:
frequency = 0.5 /s
speed = 2m/s
Explanation:
frequency = 1/period = 1/2 = 0.5 /s
speed = frequency × wavelength
= 0.5 × 4 = 2m/s

Describe how the motion of the particles within the popcorn changes as thermal energy is transferred. How do they start out? How does that change? What other transformations occur?
Answer:
Generally, when thermal energy is transferred to a material, the motion of its particles speeds up and its temperature increases. There are three methods of thermal energy transfer: conduction, convection, and radiation. ... Convection transfers thermal energy through the movement of fluids or gases in circulation cells.
Explanation:
Answer:
Why do you think transferring energy into or out of a substance can change the molecules’ freedom of movement?
Explanation:
We know that transferring energy can cause a change in molecules' freedom of movement. Another way to say this is that transferring energy into or out of a substance can cause a phase change.
