Answer: so the cycle of energy in the earth all depends on the different types of tropic levels in the ecosystem, or maybe even the use of solar power.
The plants as well they have energy in them that spreads to the earth. The photosynthesis process also helps it go through it
Explanation:
Answer: The correct option is A.
Explanation:
This is because inbreeding is the mating or organisms that are genetically related in one way or the other and it go against interchanging of DNA. This normally result in recessive traits in a population and bring about the same traits.Therefore there is more possession of two identical traits in the population and there is decrease in genetic variation because of the similar traits in offsprings genome.
Answer:
0.33hours
Explanation:
The speed of a moving body can be calculated by using the formula;
Speed = distance ÷ time
According to the information provided, the time it would take Craig to ride the skateboard on the sidewalk at an average speed of 18km/h for a distance of 6km is being asked.
Hence, derived from the above formula;
Time = Distance/speed
Time = 6/18
Time (hr) = 0.3333hr or 19.8minutes

Some of the most dramatic evidence for evolution has come from human agriculture. One of the most highly artificially selected crop plants is corn.
- Numerous branches of biology provide proof of evolution: Anatomy. Because a physical characteristic was present in a common ancestor, species may have similar physical characteristics (homologous structures). the study of molecules. The genetic code and DNA show how life has a common ancestor.
- The farmers kept the kernels from plants that had desirable traits and planted them for the harvest the following season. Artificial selection or selective breeding are terms used to describe this technique. Over time, maize cobs grew bigger and had more rows of kernels, finally taking on the shape of modern maize.
- Corn is one of the crops that has undergone the most artificial selection.
