Answer:
From each trophic stage in an ecosystem, a pyramid of energy reflects how much energy, originally from the sun, is retained or deposited in the form of new biomass. Around 10% of the energy is typically passed from one trophic level to the next, preventing a large number of trophic levels from forming.

How do endoparasites survive inside the body of the host?
Answers
Endoparasites have extreme specialisations which makes their life cycles more complex. Some examples of endoparasites are Taenia solium and Fasciola hepatica (liver fluke), etc.
The special structures possessed by endoparasites are as follows:
➥ Hooks .
➥ Dorsoventrally flattened body.
➥ High reproductive potential.
➥ Indirect development.

Please help.What would you expect to occur if you were to repeatedly lift 25 pounds over your head for 1 minute,
rest for 1 minute, and then repeat the exercise? Why do you expect this outcome?
Answers
Answer:
Strengthen the arms.
Explanation:
If a person repeatedly lift 25 pounds of weight over the head for 1 minute and then rest for 1 minute, the outcome of this exercise is to strengthen the muscles of the arms. The lifting of weight with the help of arms, the muscles of the arms will get stronger and increase occurs in the width of the arms. This exercise done by bodybuilders to get their arms stronger as well as athlete for stronger arms and hand muscles so the outcome of lifting the weight will leads to the increase in the strength of the arms.
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
Answers
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.

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.

Answers
Answer:
Explanation:
Fast-twitch muscle also uses glycolysis to produce energy, but it skips harvesting energy from pyruvate, a process that takes oxygen. Instead, pyruvate gets converted into a waste product, lactic acid, and released into the bloodstream
Answer: Lactic acid is produced in your muscles when you perform strenuous exercise. It’s produced mainly in muscle cells and red blood cells when the body breaks down carbohydrates for energy when oxygen levels are low. These levels decreases during intense exercise or when a person has an infection or disease.

Answers
Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.
What is the purpose of the theory of evolution?The Theory of Evolution states that it is the environment, through natural selection, that determines the importance of the individual's characteristic or its variations, and the organisms best adapted to this environment have a greater chance of survival, leaving a greater number of descendants.
With this information, we can conclude that Evolution is the key to understanding the history of life on our planet, since it is through it that we understand the changes in life forms over time.

Answers
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.
