Explanation:
Sugar dissolves faster in a warmer solvent than it does in a cooler solvent because particles have more energy of movement.
What is an example of a problem that a chemical engineer solves.
Answer:
Well, it would be easier if I had choices, but here's what I found:
"Chemical engineers also develop solutions to environmental problems, such as pollution control and remediation. And yes, they process chemicals, which are used to make or improve just about everything you see around you.""Another source mentioned that they use chemistry to solve everyday problems. They also help make [them] as environmentally safe as possible, and eliminate as much waste as they can."Hope this helps! :)
Indicate whether the statements below are TRUE or FALSE.
1. You work with two sugars. Glucose (MW = 180 Da) and Sucrose (MW= 342 Da). You make various solutions of each sugar separately and compare them. When you compare two 1-liter solutions containing these sugars at a 10mM concentration, there are more molecules of sucrose in 1 liter because its MW is higher than that of glucose.
2. When you compare two solutions at the same percentage concentration (e.g. 1%), the molarity (= concentration in mole/liter) is higher for glucose because the molecular weight of glucose is lower.
3. When you have 1 liter of a solution containing 90g of glucose, you must use 171g of sucrose to make a 1-liter sucrose solution with the same molar concentration.

Is a plant that has the natural ability to protect itself against predation a genetically engineered organism
Answer:
No, genetically engineered organisms are engineered by humans. The plant evolved to be this way.
Explanation:
Answer:
If it's a natural ability for the plant, it's probably not genetically engineered. It depends on the plant species/fruit.
Explanation:
Predation: A biological interaction where one organism, the predator, kills and eats another organism, its prey.
Genetically Engineered Organism: An animal, plant, or microbe whose DNA has been altered using genetic engineering techniques.
In most cases with let's say a pepper plant, the plant will produce a chemical compound called capsaicin. This is what makes the peppers spicy. It really just depends on the plant we're talking about.

Scientists once thought that life spontaneously arose from nonliving things. It took extensive experimentation and the invention of new technology to confirm the tenets that now make up the cell theory. Now, we don't even question that cells are the basic units of life and only come from preexisting cells. What technology had the biggest impact on the development of the cell theory?
A) centrifuge
B) electrophoresis
C) microscope
D) telescope
Answer:
Microscope.
Explanation:
Microscopes were extremely influential in the development of cell theory, as they allow us to see down to the level of cells and observe them. Through process of elimination, we know it cannot be a telescope (used for observing large, far away objects) or a centrifuge (separates substances based on density). Electrophoresis is moreso used for DNA, and not for the entire cells.

Explanation:
Imagine that fully functioning kidneys have been successfully created through bioengineering. What data analysis would measure the effectiveness of bioengineered organs in improving access to organ transplants among diverse groups of people, and what evidence would be needed to demonstrate that bioengineered organs have improved access
Answer:
The correct data analysis and evidence is:
Analysis: Compare the percentage of different ethnic groups who receive kidney transplants before and after bioengineered kidneys are available.
Evidence: A greater percentage of African Americans, Asians, and Pacific Islanders, and Hispanic/Latinos receive transplants after bioengineered kidneys are available compared to before
Explanation:
Bioengineered organs may be used to repair organs that have been destroyed. If the bioengineered organs are identical to the initial ones, transplantation rejection may be reduced.
So, to assess the effectiveness of organ donation adoption in people of various ethnicities, we should compare the percentage of people of various ethnicities receiving organ transplants before and after bioengineered organs became viable, and look for signs of a higher percentage of people of various ethnicities receiving organ transplantation after bioengineered organs became available.

In which numbered cells should he place pressure?
O 2, 4, and 5
O 1, 4, and 6
O2, 3, and 5
O 1, 3, and 6
The correct option is D.) 1, 3, and 6 because pressure is the changing factor in Gay-Lussac's Law, the constant factor in Boyle's Law, and the changing factor in Charles's Law.
Gay-Lussac's Law states that the pressure of a given quantity of gas held at constant volume is directly proportional to the Kelvin temperature which means the pressure of a gas increases as the temperature increases, and decreases as the temperature decreases.
Boyles Law states that the pressure of a gas is inversely proportional to its volume that means as the volume of a gas increases, the pressure of the gas decreases, and vice versa.
Charles's law is a basic physical law that states that the volume of a given amount of gas at a constant pressure is directly proportional to its absolute temperature. This means that when the temperature of a gas increases, its volume also increases, and vice versa.

Return to the MyPlate food plan calculator, and make an eating plan for someone whose weight and age are different from yours. You can change the person’s age, gender, and activity level. How does this checklist differ from yours? Why do you think the person’s energy needs are different?
Answer:
Increase consumption of food to increase weight.
Explanation:
There is my friend who is very weak and thin about 52 kg weight and he is one year older than me. I wanted to increase his weight up to 70 kg so I will recommend him to eat more nutritive food having large amount of proteins because proteins made muscles in the body. I suggest him to eat more food and exercise regularly to have a muscular body. The checklist is different from my checklist due to different goals. I wanted to lower my weight and increases the weight of my friend. My friend's energy needs are different from mine due to different goals to achieve.
Answer:
Males generally need more calories than females. Because men have an overall larger body in both height and weight, they need to consume more calories. For a male who is 20 years old, 5 feet and 10 inches, weighs 198 pounds, and has moderate physical activity, he should consume about 2,800 calories per day. That is about 1,000 calories more than my average caloric intake. To consume that many calories, he should eat 2 ½ cups of fruit, 3 ½ cups of vegetables, 7 ounces of protein, 3 cups of dairy, and 10 ounces of grains per day.

What is the greatest source of carbon that enters the ocean
from the atmosphere?
a
carbon monoxide
w
b carbon dioxide
C
bicarbonate ions
Answer:
c.)carbon dioxide
Explanation:
Most carbon enters the ocean when carbon dioxide in the atmosphere dissolves in ocean water. When carbon dioxide dissolves in water (H2O), it forms an acid called carbonic acid (H2CO3). The reaction is given by the equation: CO2 + H2O ↔ H2CO3.
