Which concept is part of the theory of evolution by natural selection
Answer:
New generations are better suited to survive than previous generations.
Explanation:
Darwin's evolutionary theory states that evolution is the slow process through which organisms change over time. Natural selection is the process by which evolution takes place. Variation in organisms, some of which offers an adaptive benefit, may be passed down from generation to generation. Better suited organisms will have a higher probability of surviving and procreating, and they will also pass on these phenotypic modifications to the offspring. Evolution is a long, protracted process because these phenotypic changes occur gradually across generations at the species level. As a result, it is anticipated that future generations would be better adapted to endure in the same environmental circumstances.

The codons are read on the amino acid table and the amino acid is determined.
Two amino acids different from those formed from the original codon pattern are methionine and tryptophan.
How are amino acids formed from codonsThe three-letter nature of codons means the four nucleotides found in mRNA
A stands for adenine
U stands for Uracil
G stands for guanine
C stands for cytosine
They produce a total of 64 different combinations but only 61 represent amino acids, the remaining three are STOP signals.
For instance, AUG is a codon that is read as methionine in the amino acid table.
Hence, the codons are read on the amino acid table and the amino acid is determined.
Two amino acids different from those formed from the original codon pattern are methionine and tryptophan gotten from one single codon.

4. How much confidence would you have in the conclusion of experiment 3 if you found out that the temperature was not
controlled? Explain your reasoning.
5. Create your own flow chart to answer a causal question.
When possible, scientists take a look at their hypotheses through the use of managed experiments. A managed test is a systematic take look at executed below-managed conditions, which means that simply one (or a few) elements are modified at a time, even as all others are saved consistently. We'll appear carefully at managed experiments within side the subsequent section.
In the three experiments, the dependent variable is evaporation, as it changes with the change in another variable.The independent variable in experiment 1 is temperature, experiment 2 is airflow, and experiment 3 is light.
The experiment can be understood better with the representation of the schematic that shows the setup to analyze how the experiment was performed. Therefore the diagram must add the schematic of the experiment.The controlled items in the experiment are the variables that are set at the particular unit to form the result. the controlled item in experiment 1 is temperature, experiment 2 is airflow from the fan, and experiment 3 is the intensity of light.The result of experiment 3 is based on the dependence on the intensity of light keeping temperature constant and controlled. If the temperature is not controlled in the experiment then it may lead to an alteration in the results as it depends on both light and temperature.The flow chart for the increase in pressure affecting the evaporation is given in the image attached.Read more about variables :

Question 5: How would you describe the effect of a 1°C increase of temperature on the biodiversity of the habitat in terms of number of populations and number of individuals in the populations? Use evidence from your graph and table to support your answer.
1°C increase of temperature can effect the biodiversity of the habitat in terms of number of populations and number of individuals in the population, it can either increase or decrease the population growth.
1°C increase in temperature on biodiversity can increase or decrease the population growth.
Population growth or change in number of individuals in the population of some organisms increases or decreases with the increase in temperature. The population of certain species such as Nassuar grouperand, Queen angelfish increases with the increase in temperature while some species such as sponges and algae decreased in population with the increases in temperature. This is because some species need high temperature to grow, so even a 1°C increase in temperature increases the population while some species need low temperature to grow, so high temperature kills them and population is decreased.
