Individuals with advantageous traits for their environment have a better chance of surviving
than those with less helpful traits. Explain how this is demonstrated in the moth information
above. Use specific information and examples.
Answer:
The moths with darker coloring lived long enough to reproduce and passed the trait on. The light peppered moths were easier for predators to spot on the dark soot covered trees so they died first.

Which evolutionary mechanism increases inheritable variations
Recombination of genes
Bottleneck ig of genes
Gene flow
Genetic drift
Answer:
Recombination Of Genes
Explanation:
Recombination of the gene's evolutionary mechanism increases inheritable variations, hence option A is correct.
What are genetic variations in a population?Gene flow, recombination, and mutation are mechanisms that enhance genetic variety. There are more mechanisms that work to promote genetic diversity, but fewer that work to reduce genetic diversity.
Demographic bottlenecks tend to decrease genetic diversity by intensifying genetic drift, but because genetic drift is random and has local impacts owing to recombination, mutation, and selection, the overall impact may vary along the genome.
Because it introduces new variety into the population, the mutation is the only mechanism of evolution mentioned that increases the amount of genetic variation. Genetic drift is the haphazard loss of genetic variation over time.
Therefore, option A is correct.

B. contact with an infected person
C. contact with contaminated food
D contact with a contaminated water
Answer:
The answers is B
Explanation:
I just took a test that had this question on it.
B. contact with an infected person
Transmission occurs when an infected person interacts or exchanges bodily fluids with another person. This can happen before the infected individual even realizes they are sick.
After a weekend field trip to the aquarium with their classmates, five pupils catch a cold. Because they may have come into contact with an infectious person, students became ill. Students became sick as a result of B. contact with an infected person

What do you call a process in which cells and organisms produce other cells and organisms of the same kind
A. reproduction
B. oxidation
C. respiration
D. perspiration
Answer:
A. reproduction
Explanation:
X- it's not oxidation because oxidation is just a reaction in which atoms of an element lose electrons
X- it's not respiration because it's literally just taking a breath; breathing
X- it's not perspiration because perspiration is just sweating
✔- reproduction is making copies of the same kind.

She fed five turtles their normal turtle food. She fed the other five carrots. All
the turtles got their normal sleep and water requirements. Then, after a week
she had a turtle race. She kept a record of the times and realized that she was
wrong. In fact, all the carrot-eating turtles finished last.
How was the dependent variable measured?

Predict one possible problem with a DNA molecules' structure that could occur.
Answer: DNA damage due to environmental factors
Explanation:
DNA is a genetic material present in the cell of living organisms. The DNA can be damaged by the environmental factors which can induce mutations in the structure of the DNA further affecting the function. The environmental factors like ultraviolet rays, chemicals, ionizing radiation can damage the structure of the DNA. For example, the chemical may contain alkylating agents which can cause the hydrolysis of the chemical bonds in the DNA.
