what is the current research saying about evolution?
Answer:
The theory of evolution is based on the idea that all species are related and gradually change over time. Evolution relies on there being genetic variation in a population which affects the physical characteristics (phenotype) of an organism.

Explain why natural selection does not operate on characteristics which affect fitness but are not heritable.
Answer:
Natural selection can only work on heritable traits. Acquired traits are not heritable and are not subject to natural selection. Environmental factors are variable. A trait that is beneficial in one place or time may be detrimental in another place or time.

Use the data and what you have learned about evolution to explain how mutation is a random process, but natural selection is not random.
The data are not found here, but evolution means 'descendence with modification', which may occur due to natural selection and mutations.
What is evolution?Evolution is descendence with modification, which generally is caused by a process called natural selection.
Natural selection 'selects' the most adaptive variants in the population, which occurs due to the emergence of mutations.
A mutation is any genetic change in the nucleotide sequence of the genome of an individual.

How does the binding affinity of a transcription factor to DNA affect the efficiency of Protein Synthesis?
Answer:
The addition of transcription factor-binding sites could affect relative DNA replication efficiency in a number of ways. Each added site could produce an additive increase in replication efficiency, or one of the added sites could be responsible for all of the observed increase in RRE.

Which two statements support the idea that energy is conserved in this example?
According to law of conservation of energy , statement B and D support the idea of energy being conserved.
What is law of conservation of energy?According to law of conservation of energy, it is evident that energy is neither created nor destroyed rather it is restored at the end of a chemical reaction .The law is now called as the first law of thermodynamics.
Law of conservation of mass and energy are related as mass and energy are directly proportional which is indicated by the equation E=mc².Concept of conservation of energy is widely used in field of chemistry, fluid dynamics.
Law needs to be modified in accordance with laws of quantum mechanics under the principle of mass and energy equivalence.This law was proposed by Julius Robert Mayer in the year 1842.

The main function of cellular respiration is to make ATP, which traps chemical energy in its bonds
Answer:
True
Explanation:
Cellular respiration is the mechanism of breakdown of food materials within the cell to release energy and the trapping of this energy for synthesis of ATP. Therefore, the main purpose is to convert energy stored in the chemical bonds of glucose to energy that the cell can use.
