Belinda asked her teacher, "What could make turtles go faster?"
Her teacher replied, "I don't know. See if you could find out."
So Belinda did a lot of research in the library and come upon the idea that
eating carrots will make turtles go faster. She decided to test her ten turtles.
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?
The amount of sleep the turtles received
How fast the turtles ate
The turtle's speed in the race
How much the turtles ate

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.

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.

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between which two reservoirs of the carbon cycle? * A. Hydrosphere and biosphere B. Geosphere/lithosphere and atmosphere C. Atmosphere and biosphere D. Hydrosphere and geosphere/lithosphere
Answer:
B
Explanation:
When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between the Geosphere/lithosphere and the atmosphere.
Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.
Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.
The correct option is B.

The characters learned to respect each other enough to discuss why the boy tried to grab the purse.
Mrs. Jones took care of the boy's hunger.
The boy asked for the money to buy shoes.
Mrs. Jones taught the boy to have manners.
The answer is the boy asked for money
Answer:
The characters learned to respect each other enough to discuss why the boy tried to grab the purse.
Explanation:
In the short story "Thank You, Ma'am" by Langston Hughes, a young, hungry boy was about to rob a woman of her purse. But as circumstances would turn out, he was unsuccessful in that attempt but then learned a valuable lesson from the very woman he had targeted.
One conflict that was resolved in the resolution was that both of the characters, Mrs. Luella Bates Washington Jones and Roger, learned to respect one another. By her act of inviting him to her home and preparing food for him, Roger also came to respect and trust the woman. It was this faith that helped them discuss the events that led to Roger's failed attempt of robbing Mrs. Jones, and Roger left the house with a sense of appreciation and a change of heart.
Thus, the correct answer is the first option.

According to the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, T is not paired with G, hence option C is correct.
What is base-pairing in DNA?Because it is RNA, there is no complementary base pairing between the bases adenine and thymine in DNA. Uracil, which has a structure remarkably similar to that of thymine, is present in place of thymine.
Base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine structure of DNA is created by the binding of these base pairs
Although they keep the two strands of DNA together, they are not strong enough to withstand replication.
Therefore, the base pairing rule, guanine always forms a bond with cytosine, while adenine always pairs with thymine, hence option C is correct.
