Which item best completes the chart?
A. Provide nutritious food for the unemployed
B. Ensure mortgages against economic recession
C. Protect again future economic crises
D. Promote foreign trade for American businesses
Answer: Protect against future economic crises
Explanation:
New Deal Agency in which unemployment is reduced and Social Security Administration prevents poverty among the elderly, protects against future economic crises again, hence option c is correct.
What is New Deal Agency?The Social Security Administration was founded in 1935 as a separate organization. Its main responsibilities were for public assistance, unemployment insurance, and old-age insurance.
Payroll taxes help to support Social Security, it covers medical expenses, medication, and in some situations, a stipend for the elderly, with New Deal Agency.
Therefore, protection from future crises in the New Deal Agency for Social Security completes the chart, hence option c is correct.

Explanation:
Example of how organisms that were previously thought of as related are actually more genetically related to organisms outside their species?
Answer:
Explanation:
Examples includes the relationships between chimpanzees, gorillas and humans. It is actually believed that the chimpanzees are more closely related to humans. About 99% of ther genome is thought similar to humans while for the gorillas about 98%.
But then, it is thought that chimpanzees and gorillas should be closely related to each other than to humans, but comparison of their genomes has shown that across 15% of the gorillas genome, they share a closer relationship with humans than with chimpanzees.
1. Chargaff’s rule states that the amount of _______ in DNA is always roughly equal to the amount of thymine, and that the amount of guanine in DNA is always roughly equal to the amount of cytosine.
2. The outside of the DNA double helix is made of alternating groups of deoxyribose sugars and _______.
3. The DNA double helix is _______, meaning that the two strands run in opposite directions.
4. What's x-ray crystallography?
5. Explain how Rosalind Franklin's x-ray crystallography work helped Watson and Crick in their quest to determine the physical structure of DNA.
6. What did Watson, Crick, and Franklin discover about the structure of DNA?
7. How did Watson, Crick, and Franklin's work reiterate Chargaff's findings?
1. adenine
2. phosphates
3. antiparallel
4. X-ray crystallography is a technique used to learn more about the three-dimensional structure of biological molecules. In x-ray crystallography, a molecule (for example, DNA) is crystallized. Then, x-ray beams are directed onto the molecular crystal. The pattern of diffraction, or bending, of the x-rays provides information about the physical properties of the molecule. Rosalind Franklin used x-ray crystallography to investigate the three-dimensional structure of DNA.
5. Watson and Crick were interested in learning more about the physical structure of DNA. They had come up with several hypotheses about how DNA could be structured, but they needed more concrete evidence of the molecule's structure. Rosalind Franklin's Photo 51 provided important information to Watson and Crick as they worked on a model of the three-dimensional structure of DNA.
6. Photo 51 confirmed that DNA is a double helix. Watson and Crick's model of DNA included that it is antiparallel, and that each base pair is held together by hydrogen bonds. The DNA chain is comprised of an outer backbone alternating between the sugar deoxyribose and phosphate groups. The base pairs, which are held together by hydrogen bonds, are located on the inner portion of the double helix.
7. Chargaff found that the number of adenine nucleotides was always roughly the same as the number of thymines, and the number of cytosines was about the same as the number of guanines. This provided the insight that in the DNA double helix, A selectively bonds with T, while G bonds with C. This explains why Chargaff consistently found that the number of As and Ts, and the number of Cs and Gs, were the same in his studies.
Answer:
adenine
phosphates
antiparallel

What term describes a species whose removal would affect many other species, both directly and indirectly
A. predator species
B. Keystone species
OC. cascading species
OD. phoresy species
Next
Answer:
Keystone species
Explanation:
Keystone species is that species whose presence and number in the ecosystem plays an important role in balancing the ecosystem and without them, the other species would be affected directly and indirectly.
A dominant predator is considered to be a keystone species because the removal of that predator allow their prey to explode in numbers which will decrease the overall biodiversity of the area. Prairie dogs, otters, bison are the examples of keystone species. So the correct answer is B. Key stone species.

Which was not produced by volcanic outgassing?
O A. Oxygen
O B. Sulfur
O C. Water vapor
O D. Carbon dioxide
Answer: A. Oxygen
Explanation:
The component that was not produced by volcanic outgassing is oxygen, while the rest of all the released during the process of a volcanic eruption.
What do you mean by Volcanic outgassing?Volcanic outgassing may be defined as an eruption that releases a gas that was dissolved, trapped, frozen, or absorbed in some material.
Volcanic eruption transfers various gases from the interior of the Earth to the atmosphere leading to outgassing which includes water vapor, carbon dioxide, and sulfur.
Therefore, the component that was not produced by volcanic outgassing is oxygen, while the rest of all the released during the process of a volcanic eruption.

Which of the following occur in a maple tree growing in a temperate climate in response to increasing cold weather? Choose three correct
answers.
A. Auxin production stimulate one final growth spurt before winter arrives,
B. The chlorophyll in the leaves break down, revealing yellow and red pigments that had been masked by the green pigments.
C. Xylem and phloem fill with ions and organic substances that prevent freezing.
D. Meristems form thick scales to protect next year's buds from cold winter temperatures,
Answer: Option A, C and D.
Explanation:
Cold temperature affects plants that cannot adapt to it and can eventually lead to their deaths.
If the temperature, and therefore the metabolism, remain low for an extended period, plant quality will suffer, and death may occur. A period of cold weather may also alter plant growth, as when certain vegetables “bolt,” or produce seed stalks, in response to several days at low temperatures
But maple plants in temperate region has develop some characteristics or adaptions that help its survive cold temperatures. Maple plants can tolerate frost and light freezes for short duration because they are cool plants and development characteristics to do so.
Auxins in them stimulate one final spurt before winter. Their xylems and phloems are filled with ions that prevent freezing.
They have a thick meristems which form thick scales to protect next year's buds from cold winter temperatures,
How does the experiment contribute to our understanding of altruism in different creatures?
Answer:
TWO YEARS AGO, a group of Ugandan chimps provided a blow to the idea that humans are the only animals that truly behave selflessly to one another. These chimps showed clear signs of true selflessness, helping both human handlers and other unrelated chimps with no desire for reward.
The question of why we help each other, instead of looking out for ourselves, is one of the most compelling in modern biology. Evolutionary and game theory alike predict that selfish behaviour should be the rule with altruism the exception, and animal experiments have largely supported this idea. Nature, ‘red in tooth and claw’, is painted as a fierce competition between selfish individuals and their even more selfish genes. In this stark landscape, true altruism is apparently a rare quality and some scientists believe that it’s one

2. What is an example of fast and dramatic erosion?
Explanation:
Erosion by Ice Ice, usually in the form of glaciers, can erode the earth and create dramatic landforms. In frigid areas and on some mountaintops, glaciers move slowly downhill and across the land. As they move, they transport everything in their path, from tiny grains of sand to huge boulders.
