Read the excerpt from The Mother of America:

Martha Washington's promotion of democratic values as America's original first lady also proved her worthy of the name "Mother of America." She realized that the way she treated the role of first lady would set precedents for future women. Martha had to figure out how to create an atmosphere that reflected democracy and commanded respect from the rest of the world. To accomplish this, she held a reception once a week where different people could enjoy refreshments and exchange ideas. Unlike other events, Martha's reception was representative of democracy, as it was open to different groups of people, including both men and women. Overwhelming respect for Martha led to others calling her "Lady Washington." Despite praise for her work, Martha disliked the restrictions put on her as the first lady and missed her son. In spite of these concerns, Martha did her duty and remained to support the president and her country. Her role in defining America's first lady—the figurative "Mother of America"—was invaluable.

Indeed, Martha Washington's roles as first lady and general's wife revealed her nurturing nature and her promotion of democratic values, making her a prime candidate for the honorable title "Mother of America."

Which of the following passages best summarizes the point and second reason of The Mother of America?

Martha understood that she would be setting the standard for future first ladies. As a result, she held receptions that encouraged people from different walks of life, including women, to discuss ideas, which was very unusual for that time. Martha attempted to establish a democratic tone that also invited respect from other nations. She missed her son greatly but continued to fulfill her duties as first lady and representative of America.
Martha Washington could be considered the "Mother of America" for her devotion to democratic values as the first lady. She understood that she would be setting the standard for future first ladies. As a result, she held receptions that encouraged people from different walks of life, including women, to discuss ideas, which was very unusual for that time. The original first lady's success at incorporating democratic values proved that she was the "Mother of America."
Martha Washington could be considered the "Mother of America." She stayed to help her husband even though she hated life in the public eye. She missed her son greatly, but she insisted on staying. She also realized that the way she treated the role of first lady would set precedents for future women. Many people loved Martha Washington and treated her with respect. They even called her "Lady Washington" to honor her.

During ripening, there is an increase in the breakdown of starch inside the fruit. The corresponding increase in the number of simple sugars which taste sweet, such as sucrose, glucose, and fructose. This process is particularly obvious in bananas as they ripen.

Explanation:

Light shining on fruit could increase the temperature in that fruit's path. If the light results in a favorable temperature, the fruit ripens.

Identify the artery and the vein in the figure below. Explain your answer.

Answers

Answer:

Artery is red, Vein is blue

Explanation:

Arteries carry oxygenated blood while veins carry CO2.

The arteries are red and the veins are blue.
Arteries carry oxygenated blood whereas the veins carry deoxygenated blood (Co2 rich blood).
The middle of the picture which looks like a web of nerves is the capillaries, this is where gaseous exchange takes place between cells and the arteries/veins.

Explain how oxygen moves into and out of the structures shown below

Answers

Explanation:

In a process called diffusion, oxygen moves from the alveoli to the blood through the capillaries (tiny blood vessels) lining the alveolar walls. ... From the heart, this blood is pumped to the lungs, where carbon dioxide passes into the alveoli to be exhaled.

The process that is shown in the structure is called diffusion. The structure shows the movement of oxygen from the alveoli to the blood.

What is diffusion?

Diffusion is a process of movement of a substance from a higher concentration to a lower concentration region. This movement is according to the concentration gradient. This process doesn't need any energy because of the movement according to the concentration gradient.

The capillaries (small blood vessels) lining the alveolar walls allow oxygen to diffuse from the alveoli to the blood throughout this process. This blood is pushed from the heart to the lungs, where carbon dioxide enters the alveoli and is expelled.

Thus, the process is diffusion, in which the oxygen moves from a higher concentration to a lower concentration.

To increase the probability of successful reproduction, there are specialized plant structures such as brightly colored petals to attract potential pollinators and extended stamens that require animals to brush against the plants in order to receive the nectar.

Explanation: (Hope this helps!)

Answer:

Because everyone has different answers, here is a possible answer you may took. Hope this helps.

Explanation:

Claim: How does plants reproduce?

Evidence: They reproduce by their structures.

Reasoning: The structures of a plant work together so they have the ability to reproduce. The roots absorb the nutrients. The stew helps to keep the tree or plant straight so it don't fall. And the branches are used to transport the water and nutrients into all the parts of the plant.

What is produced by the process of meiosis?

A.
Cells that are an exact copy of the parent cell.
B.
Cells that are exact copies of all the other daughter cells.
C.
Cells that contain half of the number of chromosomes present in the parent cell.
D.
Cells that contain the exact number of chromosomes present in the parent cell.

Answers

Answer:

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for reproduction. So basically saying, C is the right answer.

Explanation:

C.cells that contain half of the number of chromosomes present in the parent cell

For how many two-digit primes is the sum of the digits equal to 8?

Answers

3 two-digit primes. 17, 53, and 71

Hope this helps !!

You'll need a list of 2-digit prime numbers, shown below:
11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97

The first one on the list that qualifies is 17, because 1+7=8. So check out the rest on the list. I find a total of three, including 17.

First, we list all the two-digit numbers with a digits sum of 8:

17, 26, 35, 44, 53, 62, 71, 80

Clearly, 26, 44, 62, and 80 are not prime. 35 is not prime, but 17, 53, and 71 are (we can verify this by dividing each number by all the primes less than its square root.

Mitosis produces cells used for growth and repair, while meiosis produces cells used for reproduction.
B.
Mitosis is only used by single-celled organisms, while meiosis is only used by multicellular organisms.
