Answer:
The third answer
Explanation:
They ran at the same speed because if you divide 7.2 by 2 it equals 3.6!
And 3.6 x 2 = 7.2 They may have traveled for different periods of time but if they had traveled at the same time and ended at the same time their speed would be the same.
Answer: It depends on if your only talking about plants if so the answer is coal.
Explanation: The reason being because coal only forms from the compaction of dead plants whereas petroleum forms from compacted plants and animals.
Using the graph provided with the question, we are able to find that that for a concentration of 270 micromol per kilogram, the calcification rate is 20 mmol calcium carbonate per meter squared per day.
Using this calcification rate,
30 = 20 * 1 * days
days = 1.5
The deposition will require 1.5 days.
Answer:
Cellular respiration
Explanation:
Respiration is the process by which energy is made. Aerobic respiration requires oxygen.
All the other processes listed do not require oxygen to.
Answer:
Empirical evidence of his ideas
Explanation:
The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.
