Decide which image you would include in a yearbook project about Elizabeth Cady Stanton. Tell what text you would write to go with the image, and explain why you selected the image
Answer:
Decide which image you would include in a yearbook project about Elizabeth Cady Stanton. Tell what text you would write to go with the image, and explain why you selected the image
To answer that question I said that: I would pick the second picture because it shows a close up view of just her and so it wont be confusing because the other picture had two people.
I prefer the second image of Elizabeth Candy Stanton in a yearbook project. The image determines her leadership towards the women's rights movement.
Who is Elizabeth Candy Staton?
She was an American writer and activist who was a leader of the women's rights and suffrage movement in the U.S. She formulated the agenda for women's rights that guided the struggle well.
Stanton changed the social and political landscape of the United states of America by providing rights for women and slaves.
She established the National Women's Suffrage Association (NWSA) whose main goal is to secure the vote for women and supported a variety of reforms that aimed to make women equal members of society.
The word suffrage means the right to vote Women in the United states fought for suffrage since Andrew Jackson's presidency.
I preferred the second image because it depicts the dedication of Elizabeth to provide equal rights to women as men.

The first energy-generating steps in glycolysis begin when glyceraldehyde 3-phosphate undergoes an energetically favorable reaction in which it is simultaneously oxidized and phosphorylated by the enzyme glyceraldehyde 3-phosphate dehydrogenase to form 1,3-bisphosphoglycerate, with the accompanying conversion of NAD+ to NADH. In a second energetically favorable reaction catalyzed by a second enzyme, the 1,3-bisphosphoglycerate is then converted to 3-phosphoglycerate, with the accompanying conversion of ADP to ATP. Which of the following statements is TRUE about this reaction?
a. The cysteine side chain on the enzyme is oxidized by NAD+.
b. The energy stored in the phosphate bond of glyceraldehyde 3-phosphate contributes to driving the reaction forward.
c. The ΔG° for the oxidation of the aldehyde group on glyceraldehyde 3-phosphate to form a carboxylic acid is more negative than the ΔG° for ATP hydrolysis.
d. The reaction glyceraldehyde 3-phosphate---->1,3-bisphosphoglycerate should be inhibited when levels of NADH fall.
Answer:
The answer is option B.
Explanation:
It is stated that "the enzyme glyceraldehyde 3-phosphate dehydrogenase to form 1,3-bisphosphoglycerate" which indicates that the energy from the broken bonds of the glyceraldehyde 3-phosphate provides energy for the reaction to take place.
So the correct answer is option B.

The surface area and volume for four cells are given. Which combination of cell dimensions would be considered the MOST metabolically favorable?
A. cell 1: surface area 14 mm^2, volume 33 mm^3
B. cell 2: surface area 20 mm^2, volume 12 mm^3
C. cell 3: surface area 7 mm^2, volume 17 mm^3
D. cell 4: surface area 5 mm^2, volume 2 mm^3
Answer:
D
Explanation:
This is because a bad ratio would be one where the volume is larger than the surface area. Once a cell's volume is larger than the surface area, there's not enough surface area to process all the products coming in and waste coming out. Ideally, you'd want a surface area and volume to be as close to each other as possible in number, but you'd rather have the volume be less than the surface area.

which cell is placed into a hypotonic environment
Answer:
I can’t see the cells you’re referring to, however, if there is a cell that is larger than the initial portrayal of the cell, that one is in a hypotonic solution.
Explanation:
Hypotonic solutions are solutions in which the ratio of solvent to solute is low. This allows more water particles to flow into the cell, thus making it appear larger.

Explain why resistance to antibiotics is considered an example of the process of evolution
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

Explain the relationship between coral and algae, and how a problem with algae photosynthesis caused coral bleaching in the Great Barrier Reef.
The relationship between Coral and Algae and how a problem with Algae photosynthesis caused Coral bleaching in the Great Barrier Reef happens in a way that when Coral reefs become stressed as a result of changes in condition such as the temperature, lights or nutrients,These Coral beef therefore expel the symbiotic algae living in there tissue which they have feeding relationship with, the expulsion of those algae will make them to turn to white completely.
However,warmer water temperatures can give rise to Coral bleaching.
The relationship between coral and algae is mutualism.
There is a mutualistic relationship between corals and algae because both coral and algae provides benefits to each other. The coral provides a protected habitat and raw materials which the algae need for photosynthesis. whereas the algae produce oxygen and remove waste materials from coral.
A problem with algae in the process of photosynthesis caused coral bleaching because warm water restrict algae from photosynthesis which leads to the death of algae which results in the coral bleaching in the Great Barrier Reef so we can conclude that the relationship between coral and algae is mutualism.

Identify EITHER one nitrogen compound OR one phosphorus compound that is considered a pollutant when released by human activity into the environment. For the compound you identified, describe the human activity and a specific environmental problem that results.
Answer:
Sodium tripolyphosphate (STPP)
Explanation:
Sodium tripolyphosphate (STPP) is a compound of phosphorus that is used to manufacture detergent.
This chemical is released into the environment when detergents are used to wash dishes or in laundry.
This compound finds its way into water bodies and leads to overgrowth of algae. This is known as eutrophication.
As these algae die, decomposition of the organisms lead to a drop in oxygen level of water bodies and increase in biochemical oxygen demand. As a result of these, some aquatic species may begin to die or relocate to other water bodies.

In your summary be sure to use at least two of the following terms cells, energy, organism, macromolecules, homeostasis
Answer:B
Explanation:
Answer:
The Grand View College (GVC) 2 focuses on understanding the basic components, structures, and functions of living organisms. This includes exploring the cells, macromolecules, and processes that allow an organism to have homeostasis and to obtain, use, and store energy.
Cells are the basic unit of life and have many complex components and functions. They have specialized membranes and organelles, are capable of moving, and interact with their environment to maintain homeostasis. Understanding how these components work together and the ways they communicate is essential.
Macromolecules, such as proteins and carbohydrates, are responsible for the majority of the work done by cells. A deeper understanding of macromolecules helps one understand how cells interact with the environment and how they use energy.
Energy is vital for organisms to maintain their homeostasis. This energy can come from sunlight, chemical reactions, and respiration. Understanding how these processes interact with the cell’s structure and components can help explain the role energy plays in an organism.
Homeostasis is essential for any organism to remain healthy and function properly. It is the result of a combination of factors, including the cell’s structure, components, and potential hazards in the environment. Knowing how organisms handle these factors is important to understanding their ability to maintain homeostasis.
The GVC 2 is a great way to delve deeper into biologists’ understanding of living organisms. By examining the components, structures, and processes that make up an organism, it becomes easier to understand the role they play in its ability to maintain homeostasis and use energy efficiently.

Levi decides to examine the effect of fertilizer on the growth of tomato plants. He chooses four plants for his experiment and applies varying amounts of fertilizer to the three of them. He does not apply fertilizer to one plant. Over a 15-day period, the plants receive fertilizer on Days 1, 4, 7, 10, and 13. Levi measures the height of all of his plants with a meter stick on Days 3, 6, 9, 12, and 15. He also makes sure to hold all experimental factors constant except for the fertilizer. Which statement describes what Levi did to prepare the control group in his experiment?
This question is incomplete because the options are missing; here are the options:
Which statement describes what Levi did to prepare the control group in his experiment?
A) Levi held all experimental factors constant except for fertilizer.
B) Levi did not apply any fertilizer to one of his plants.
C) Levi applied different amounts of fertilizer to three of his plants.
D) Levi measured his plants on five separate days.
The answer to this question is B. Levi did not apply any fertilizer to one of his plants.
Explanation:
In an experiment, the control group refers to the subject or subjects, in this case, the plants, that do not receive the treatment or variable tested by the researcher. This implies the control group for Levi is the plant with no fertilizer because this is the only plant that does not receive the treatment or fertilizer. Moreover, this acts as a control group because Levi can use this plant to determine if the growth of the other three plants is positively or negatively affected by the use of the fertilizer.
