Hope it is helpful...a mass extinctions is
Answer:
Mass extinction is when biodiversity or species in a living habitat decreases to about three-fourths of its original number or to none. Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms. It occurs when the rate of extinction increases with respect to the rate of speciation. Mass extinctions are usually associated with organisms that are macroscopic rather than microscopic. Examples of mass extinctions are Permian extinction of marine species, and Cretaceous extinction of various species, including dinosaurs.

How does the population of red-tailed hawks affect the population of prairie dogs living in the meadow? How does the population of prairie dogs affect nonliving parts of the meadow, such as soil? Help, please.
Answer:
Explanation:
Red tailed hawks will often prey on prairie dogs. The hawks will eat the prairies dogs so they will lessen the population. Prairies dogs create more fertile soil, so this allows plants to germinate, or grow. This results in more food for prairie dogs and thus more food for hawks.

Do you think there should be government regulation against known carcinogens? Why or why not? Write a 5-6 sentence paragraph that states your opinion and explains the reasons for it.
Answer:
Yes,there should be government regulation against known carcinogens;
Because of following reason;
food containing carcinogens cause food poison,cancer and effect our health negatively.it degrades the immunity power of us which makes us weak.if regulations is made people be awared and stop consuming those type of food.people start to consume good diet.Answer:
Yes. I believe that there should be government regulation against known carcinogens. Take food into consideration. Before President Roosevelt passed the first Food and Drug Act, mothers would quite literally feed their children formula that could have heroin in it or any unregulated substance, because companies could do so without any repercussions. Meat factories were dangerous and its no secret that there were a significant amount of rats that fell into the meat. After this act was passed in the United States, factories cleaned up their conditions and food became somewhat safe to eat. This act protected the consumer and made them aware of what they were literally consuming. Why is this different from government regulation against carcinogens? Did you know that bug spray can contain carcinogens? Old fridges? Granite countertops? Weedkiller? Because I did not. Consumers should be aware of the contents of the things they are buying. Corporations SHOULD be held responsible for putting customers in harms way. Government legislation should be passed to protect those who do not know better. Because we should not have to know better. We should already know.

Granite is composed of coarse-grained quartz and feldspars in varying proportions and due to the varying proportions of these two constituent materials, the texture of granite varies as shown in the image.
Thus, option C is correct
Options A and B and D are incorrect because the constituent material of granite is not fixed. It varies from from place to the other.
Move the bonfire to the left side of the sand. Observe how the smoke from the bonfire moves"" Dose anyone know how to get past this?
Fire requires three things heat, fuel, and oxygen. The heat source is a match. The firewood burns and provides its own heat to keep it burning. Fire needs oxygen, which can be obtained from fresh air. Air gets hot and denser.
When fire burns, heat transfers kinetic energy to the molecules. As the kinetic energy increases, there are more collisions between molecules. The hot air becomes less dense. As less dense than the cold air around it, the hot air rises and carries the smoke with it. Therefore, the smoke moves away with the wind.

2. What does it mean for your body to be out of homeostasis?
Answer:
If homeostasis is disrupted, it must be controlled or a disease/disorder may result. Your body systems work together to maintain balance. If that balance is shifted or disrupted and homeostasis is not maintained, the results may not allow normal functioning of the organism.
Explanation:
One way to determine the density of animals in an area is to use the mark-recapture technique. A number of individuals from a population are captured, marked so they are easily identifiable, and released back into the population. It's assumed that the captured and marked animals will randomly mingle with the rest of the population. Later, the population is re-sampled and the number of marked and unmarked animals is recorded. The following equation can then be used to estimate the size of the entire population.
Number of individual marked in first catch/Total population size, N = Number of individual marked in 2nd catch / Total number of 2nd catch
If 25 Prairie Dogs were captured, marked, and released back into their population, and then subsequently 135 Prairie Dogs were captured, of which 18 were marked, what is the approximate total population size, N?
Answer:
N = 187.55
Explanation:
Here you just need to replace the terms and clear the equation.
You already know that,
First capture: 25 prairie dogs.First marked animals: 25 (the whole first capture)You let these animals leave and then you made another capture.
Second capture: 135 prairie dogsAlready Marked animals: 18 (these 18 dogs were caught in the first capture and marked before releasing them)To know the size of the prairie dogs population you just need to use the following equation and clear N, which is the value that you are looking for.
Number of individual marked in first catch/Total population size, N = Number of individual marked in 2nd catch / Total number of 2nd catch
Number of individual marked in first catch = 25 dogsTotal population size, N = this is what we want to knowNumber of individual marked in 2nd catch = 18 dogsTotal number of 2nd catch = 135 dogsSo now, we need to replace terms
25 / N = 18 / 135
25 / N = 0.1333
N = 25 / 0.1333
N = 187.55

Explain the role of insulin in the homeostatic regulation of blood glucose levels
Answer:
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.

How are primary and secondary succession similar and how are they different?
Answer:
They are similar in that both involve the growth of new organisms in an environment. However they differ in that primary succession occurs in a place where no life had been before, while secondary succession occurs in place where life had been before, but was destroyed.
Some examples of primary succession include the formation of a new ecosystem after a volcano, glacier outbursts, or a nuclear explosion. Some examples of secondary succession include succession after fire, harvesting, logging, or abandonment of land or the renewal after a disease outbreak.
Answer:
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
The mutation rate is the probability of a single gene mutating in an offspring bug.
a. True
b. False
Answer:
True
Explanation:
A mutation is any alteration in the genetic sequence of the genome of a particular organism. Mutations in the germline (i.e., gametes) can pass to the next generation, thereby these mutations can increase their frequency in the population if they are beneficial or 'adaptive' for the organism in the environment in which the organism lives (in this case, an insect/bug). The mutation rate can be defined as the probability of mutations in a single gene/locus/organism over time. Mutation rates are highly variable and they depend on the organism/cell that suffers the mutation (e.g., prokaryotic cells are more prone to suffer mutations compared to eukaryotic cells), type of mutations (e.g., point mutations, fragment deletions, etc), type of genetic sequence (e.g., mitochondrial DNA sequences are more prone to suffer mutations compared to nuclear DNA), type of cell (multicellular organisms), stage of development, etc. Thus, the mutation rate is the frequency by which a genetic sequence changes from the wild-type to a 'mutant' variant, which is often indicated as the number of mutations per round of replication, per gamete, per cell division, etc. In a single gene sequence, the mutation rate can be estimated as the number of de novo mutations per nucleotide per generation. For example, in humans, the mutation rate ranges from 10⁻⁴ to 10⁻⁶ per gene per generation.
