The process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).
Cellular respiration refers to the reactions by which aerobic cells normally produce energy in the form of ATP by using energy stored in the chemical bonds of foods and oxygen.Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).Acid lactic fermentation is energetically much less efficient than cellular respiration, but ATP production in cellular respiration is much slower than in fermentation, thereby muscle cells use this pathway (fermentation) when they cannot get oxygen fast enough to meet their energy requirement.In conclusion, the process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).

There are two species of squirrel in the United Kingdom: red squirrels and gray squirrels. Red squirrels are native to the United Kingdom while gray squirrels were introduced to the United Kingdom from North America in 1876. Figure 1 show the distributions of the two squirrel species in 1945 and 2010.
Answer:
The grey squirrel has increased their rate of emigration to the UK
The grey squirrel has increased their rate of emigration to the UK.
What is emigration?Emigration is the act of relocating away from a resident country or place of residence (to permanently leave a country). Contrarily, immigration refers to the flow of individuals from one country into another (to permanently move to a country).
A migrant leaves their home nation and moves to their adopted one. Emigration and immigration thus both describe migration, but from the perspectives of various nations.
Demographers look at the push and pull factors that cause people to be drawn to one place and pushed away from another. Desires to escape unfavorable situations, such as scarcity of land or employment opportunities, or unfair treatment, are possible.
Therefore, The grey squirrel has increased their rate of emigration to the UK.

In other cases, researchers use natural experiments in which the dependent variable (typically a measure of organism health) is measured under differing contexts that are not manipulated. Say, for example, that an accidental chemical spill contaminates five ponds. To determine the possible effects of the toxic chemical on frogs, a researcher could compare the hatching rate of frog eggs laid in those five ponds to the hatching rate of eggs laid in five uncontaminated ponds nearby. This would be an example of a natural experiment because concentrations of the toxic chemical in the ponds were not controlled by the experimenter, but rather resulted from the chemical spill.
Drag type of experiment on the left to the example of experiment on the right.
A. Natural
B. Manipulative
1. ______: Blood concentrations of BPA in college students are compared to their recent consumption of canned food items
2. _____: The feeding behavior of fish in streams that receive acidic runoff from strip mines is compared to the feeding behavior of fish in unaffected streams.
3. _____: The deformity rate in baby birds from nests in pesticide-sprayed fields is compared to the deformity rate in birds from nests in unsprayed fields.

5. ______: Foraging activity levels are compared in tadpoles exposed to four concentrations of toxic metals in the laboratory.
6. ______: Growth of corn plants is compared in field plots sprayed with three different dosage:s of weed killer 7.
7. ______: BPA concentrations in the urine of people with diabetes are compared to BPA concentrations in the urine of people without diabetes
Answer:
1. Natural
2. Natural
3. Manipulative
4. Manipulative
5. Manipulative
6. Manipulative
7. Natural
Explanation:
1. Checking the blood concentration of BPA in college students in relation to their recent consumption of canned food items is a natural experiment because BPA concentration in blood is not artificially controlled by any means.
2. Comparing the feeding behavior of fish in streams with acidic runoff to that of fish in an unaffected stream is a natural experiment due to the fact that the acidity of the stream is not artificially controlled in any way by the experimenter.
3. Checking the deformity rate in baby birds from nests in pesticide-sprayed fields and that from unsprayed fields would require some manipulations except a sprayed and unsprayed one already existed long before the experiment was given birth to. Otherwise, the sprayed field might need to be artificially created just for the purpose of the experiment.
4. A known carcinogen would need to be administered to a group of the mice. This is manipulative.
5. The tadpoles would need to be artificially exposed to the toxic metals in the laboratory. Manipulative
6. The spraying would need to be carried out artificially in order for the comparison to be made. Manipulative
7. People with diabetes cannot be artificially created. They must have existed naturally long before the experimental design. Natural

Yellow light travels through a certain glass block at a speed of 3 * 108 m/s . The wavelength of the light in this glass is 3.81 * 10 - 7m . What is the frequency?
Answer:
f = 7.87×10¹⁴ Hz
Explanation:
Given data:
Speed of light = 3×10⁸ m/s
Wavelength of light = 3.81 ×10⁻⁷ m
Frequency of light = ?
Solution:
Formula:
Speed of wave = wavelength × frequency
Now we will put the values in formula.
3×10⁸ m/s = 3.81 ×10⁻⁷ m × f
f = 3×10⁸ m/s / 3.81 ×10⁻⁷ m
f = 0.787 ×10¹⁵ s⁻¹
s⁻¹ = Hz
f = 0.787 ×10¹⁵ Hz
f = 7.87×10¹⁴ Hz
Which chemical is released by (2) WBC's that produces a non-specific inflammatory response?
Answer:
cytokines
Explanation:
Non-specific immune responses are integral to host cellular defense mechanisms. It is a general response, mediated by white blood cells, where cells rapidly react to pathogenic infiltration.
Here receptors on cells recognise molecules shared by a broad spectrum of pathogens, or even react to signals from damaged, injured or stressed cells like inflammatory cytokines in a cytokine storm.
Create an example in which a mutation entered the gene pool and due to predator pressure. Becomes predominate. For example, think about how the color of the Peppered moths during the industrial revolution changed. The moths were light in color, but due to all the pollution from industry the trees they lived on turned dark making the light moths an easy target for birds. The moths with the mutation for dark color were able to blend with the darker bark and survived. These dark colored moths passed their genes on to their offspring and over a relatively short period of time most of the moths became dark. When the pollution decreased, the lighter colored moths predominated once again.
*Write a paragraph or so it can be a little under. Ill give you brainiest.*
Answer:
The population of light colour Peppered moths decreases and dark Peppered moths increases.
Explanation:
During the industrial revolution, the population of light colour Peppered moths decreases and dark Peppered moths increases because due to industrial revolution, air pollution increases which spreads a black dust on the trees and as a result the light colour Peppered moths can easily be seen in the dark by its predator and feed on them while dark colour Peppered moths can't be seen in the dark so the predator is unable to feed and as a result the population of dark colour Peppered moths increases.

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each? Meiosis has four cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has two cell divisions and results in two identical daughter cells. Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells. Mitosis occurs in gametes to increase genetic variation in daughter cells, while meiosis occurs in body cells for growth and repair. Mitosis produces genetic variation in daughter cells and increases the number of chromosomes, while meiosis occurs in body cells for growth and repair.
Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.
The main differences would be that Meiosis has 4 cell divisions and Mitosis had 2 cell divisions. Meiosis results in 4 haploid daughter cells and Mitosis results in 2 identical daughter cells.
Another big difference between the two could be that Meiosis produces genetic variation in the daughter cells and increases the number of chromosomes whilst Meiosis occurs in body cells for growth and repair. Each process has a different job.

What is the role of an enzyme in a reaction with the reaction ? would the reaction happen without an enzyme?
Answer:
Enzymes are not used up in a chemical reaction. Usually, the enzyme will “reset” and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction.
Explanation:
Enzymes serve a similar purpose for chemical reactions in an organism's body, which is to lower the amount of "activation energy" needed for a particular chemical reaction to occur. Without enzymes, many chemical reactions would occur at a much slower rate because the amount of activation energy required would be far greater.
