<u>Answer</u>: B.The heliocentric model shows that Earth revolves around the Sun. The geocentric model shows that the Sun revolves around Earth.
The geocentric model is also known as the Ptolemaic model and had as center of the Universe Earth. However, the heliocentric model presented by Nicolaus Copernicus and Galileo Galilei, had the sun as the center of the Solar System, with Earth orbiting around it. However, it is thought that this theory was older than Copernicus.
Volume of a cylinder formula:
V= h(pi×r^2)
If the diameter is 10in, then the radius is 5in
Substitute given values into the formula:
V=20(3.14×5^2)
V=20(78.5)
V=1570in
Answer:
The most likely preferable option will be - A.
A. Insects.
Explanation:
The basic features of insects -
- Insects have an exoskeleton outside of their body or a shell-like covering on the outside of its body.
- Insects have a body with three segments: head, thorax, and abdomen.
- Insects have two large eyes and a pair of antennae on top of their heads.
- Insects have six legs (3 pairs).
- Insects have two pairs of wings on the dorsal part of their body.
Answer:
1. ridges and trenches (either answer is acceptable)
2. mid-atlanitc
3. subduction zone
4. molten
5. oceanic trenches
Explain:
6. Rocks in the ocean eventually get subducted back into earths mantle due to slab pull. New rocks form at mid-ocean ridges as ridge forces two plates to diverge.
Answer:
Plants perform photosynthesis and cellular respiration.
Explanation:
- Cellular respiration is the conversion of glucose into ATP and energy yielding molecules such as NADH and FADH2 along with water and oxygen and carbon dioxide as by-products.
- Cellular respiration is a process that occurs both in autotrophs and heterotrophs.
- Only the final stage of cellular respiration i.e. oxidative phosphorylation or electron transport chain requires oxygen as the final electron acceptor.
- Heterotrophic cells don't take in carbondioxide, they utilize glucose obtained through food.
