4. Which is NOT a primary color?

Which is NOT a primary color?
Red
Three Primary Colors (Ps): Red, Yellow, Blue. Three Secondary Colors (S’): Orange, Green, Violet. Six Tertiary Colors (Ts): Red-Orange, Yellow-Orange, Yellow-Green, Blue-Green, Blue-Violet, Red-Violet, which are formed by mixing a primary with a secondary.

5. What is the main gas in the Earth’s atmosphere?

What is the main gas in the Earth’s atmosphere?
Nitrogen is the most plentiful gas on the earth. The most abundant naturally occurring gas is Nitrogen (N2), which makes up about 78% of air. The Earth’s atmosphere comprises approximately 78 % nitrogen, 21 % oxygen, and 1 % argon.

6. What is the process by which plants make their food?

What is the process by which plants make their food?
Photosynthesis: The plants produce their own food by a process called photosynthesis. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize food from carbon dioxide and water. Chlorophyll present in the chloroplast as a green pigment can trap the solar energy.

7. Which is the largest planet in our solar system?

Which is the largest planet in our solar system?
Jupiter is the fifth planet from our Sun and is, by far, the largest planet in the solar system – more than twice as massive as all the other planets combined. Jupiter’s stripes and swirls are actually cold, windy clouds of ammonia and water, floating in an atmosphere of hydrogen and helium.

8. Which of these is a mammal?

11. What part of the plant conducts photosynthesis?

What part of the plant conducts photosynthesis?
The vast majority of chloroplasts are found in the cells of the mesophyll. Even more specifically, the palisade layer has the most chloroplasts, so the greatest amount of photosynthesis occurs in that leaf layer.

12. What force pulls objects toward the center of the Earth?

What force pulls objects toward the center of the Earth?
Gravity is the force that pulls all objects in the universe toward each other. On Earth, gravity pulls all objects “downward” toward the center of the planet.

13. Which of these is NOT a state of matter?

14. What gas do plants breathe in that humans and animals breathe out?

What gas do plants breathe in that humans and animals breathe out?
People inhale oxygen that is in the air, and exhale carbon dioxide. Trees do the opposite. So they take in what you exhaled, they take in carbon dioxide and they give out oxygen.

15. What planet is known as the “Red Planet“?

What planet is known as the “Red Planet“?
Mars is often known as the Red Planet.
