The carbon that plants need for photosynthesis comes from carbon dioxide, or CO2 that's present in our atmosphere. Hope it helps
A genotype is the genetic makeup if an organism. So let's say we have the freckles gene with freckles (F) being dominant and no freckles (f) being recessive. Let's also say Bob is heterozygous so his genotype for the freckles gene would be Ff. If he was homozygous dominant, he would have the genotype FF and if he was homozygous recessive, he would have the genotype ff.
Hello,
A geologist finds a large rock containing a seashell. What does this tell you about the area at the time the rock was formed?
The answer might be B. The area was covered by water
<u>Answer</u>:
Concave shape of the wave rock is a physical evidence that supports the evolution of earth due chemical weathering
<u>Explanation</u>:
It is the best physical evidence of collection in the earth’s evolution. The earth surface is 2.7 billion years old, also the basis for formation of Australian continent formation. The wave rock is formed by weathering of the surrounding area, which helps in proving the deposition part, as the wave rock was below the ground, occurred due to deposition of rock years over years. It is made from very tough material from its surrounding. The weathering reduced the surrounding terrain, while the bedrock remained to witness for the history.
