Question 1. What change led to an increase in the number of light-colored moths within the population?
1. More mutations
2. Decreased pollution
3. More dark colored trees
4. Fewer humans
Question 2. Claim: Individuals in a population have genetic variations that can be passed on to their offspring. Refer back to the rabbits in the desert from the natural selection activity we did in class. How could an organism's traits influence the survival rate of the population?
Answer: 1. 1. More mutations. 2. According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

Explain the difference between oxidation and digestion.
The one that is loosing electron is oxidation process and the one that is gaining electron is reduction.
b) Reduction reaction occur at cathode while oxidation reaction occur at Anode.
Explanation:
The main difference between the reduction and oxidation process is based on gaining and loosing of electron.
Reduction and oxidation both occur simultaneously. one is loosing electron and other is gaining. The one that is loosing electron is oxidation process and the one that is gaining electron is reduction.
B) Reduction reaction occur at cathode while oxidation reaction occur at Anode

Explanation:
Energy Efficiency =
Useful Energy Output/Total Energy
Input x 100 (%)
If a power plant uses 100 units of
energy to create electricity and the
output is 5 units, where does the
95% of the energy input go?
A. lost as heat
B. lost as gas
C. escapes the system as potential energy
If a power plant uses 100 units of energy to create electricity and the output is 5 units, 95% of the energy input goes as lost as heat.
Could you ever create a machine where 100% of the input energy would turn into output energy?No, a real machine can't have an efficiency of 100%. An efficiency of 100% means that there is no loss and the output energy (or work) of the machine is equal to input energy (or work). In real machines, there is always some loss of energy to overcome friction and air resistance.
How do you calculate the energy efficiency of a power plant?To express the efficiency of a generator or power plant as a percentage, divide the equivalent Btu content of a kWh of electricity (3,412 Btu) by the heat rate. For example, if the heat rate is 10,500 Btu, the efficiency is 33%. If the heat rate is 7,500 Btu, the efficiency is 45%.

What do you mean by Constellations?Constellations may be defined as clusters of stars that form a recognizable pattern and were imagined in order to construct noticeable and apparent configurations of objects or creatures in the sky, especially at night.
These groups of stars are also present in the day but they are not perceived due to the extremely high light of the sun. So, they form patterns in the night sky. These groups of stars are not specifically present as they are distributed randomly and can form new images.
Therefore, the correct options for this question are A, B, and D.

The theory of evolution through natural selection is considered a scientific theory because _____. See Concept 22.3 (Page 475) The theory of evolution through natural selection is considered a scientific theory because _____. See Concept 22.3 (Page 475) it is broad enough in scope to explain many observations it is supported by a massive body of evidence from many disciplines it is general enough to provide many testable hypotheses All of the above are correct. None of the above is correct.
Answer:
All of the above are correct:
it is broad enough in scope to explain many observations it is supported by a massive body of evidence from many disciplines it is general enough to provide many testable hypothesesExplanation:
The scientific theory is a conceptual framework used to explain facts or phenomena and to make predictions.
The theory is fundamental to science because it allows scientists to organize and understand observations.
The construction of a theory begins with a hypothesis. The scientist believes that a phenomenon occurs in a certain way, so he/she performs observations under the scientific method to prove that his/her hypothesis is valid or not valid. The systematization of the observations and the empirical data collected might derive from a scientific theory that explains the analyzed phenomenon.
A scientific theory is a knowledge that has been contrasted in several ways.
The theory of evolution has been tested in too many ways and by different disciplines, becoming one of the most strong theories. Research areas such as biology, genetics, paleontology, and geology, among others, have been tasting it and explaining many facts from it, which makes it broad enough to base on it any explanation of life.
