How has vehicle fuel consumption in comparison to miles traveled changed since 1960? What is the likely cause for this change?
Answers
Answer:
After World War II, economic growth, population growth, rapid suburbanization, and the closing of some public transit systems led to more reliance on personal vehicles for transportation. The number of cars and trucks in the United States increased dramatically, as did the number of highways. One result of the rapid increase of motor vehicles was air pollution, especially in cities, that had serious impacts on public health and the environment.

this year there were 32 ants born in an ant hive. Due to the new pesticide that was used in the area, 32 died. With an overall population of 1000 ants in the hive, what is the change in population? Do you have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. Work for calculating the new population.
Answers
Answer:
0 change in population. I think.
Explanation:
first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.
Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.

It takes energy for an organism to produce a particular structure such as a stripe on a clover leaf that is otherwise plain.
Why might cyanide-producing clover produce striped leaves?
Answers
Answer:
increases its ability to resist predation because the snails that eat it die
In general, two types of white clover can be found in a variety of habitats around the world. The first has plain green leaves, while the second produces cyanide as a defensive strategy against herbivores and signals its presence with white stripes on the leaves.
What are defensive behavior?Claws, teeth, disguising, poison, imitation, and adaptations such as echolocation are all common defense mechanisms. Some are uncommon but extremely effective.
A nonhuman animal's behavior to avoid of been hurt or killed by another.
This could include defensive aggression against a potential predator or a member of its own species, from its own group or from another group, or animal escape actions to avoid the source of harm.
In general, two types of white clover can be encountered in a variety of habitats worldwide.
The first has plain green leaves, whereas the second, as a defensive mechanism against plant eating organisms, produces cyanide and signals its presence with white stripes on the leaves.

what experiments led to the discovery of dna as the hereditary material?
Answers
Answer:
In the 1920s, Frederick Griffith He was studying two different strains of a bacterium, called R (rough) strain and S (smooth) strain. He injected the two strains into mice. The S strain killed (virulent) the mice, but the R strain did not (non-virulent). Griffith also injected mice with S-strain bacteria that had been killed by heat. As expected, the killed bacteria did not harm the mice. However, when the dead S-strain bacteria were mixed with live R-strain bacteria and injected, the mice died.
