Which of the following values best represents the amount of energy available for primary consumers in the food chain?
The value which best represents the amount of energy available for primary consumers in the food chain is: C. 93,000 kilocalories.
What is a food pyramid?A food pyramid is sometimes referred to as a food chain, or pyramid of energy and it can be defined as a model that is used to depict the food chains and flow of energy from one trophic level (feeding level) to the next in a single ecosystem.
This ultimately implies that, a food chain is a pictorial diagram that compares the energy used by living organisms at each trophic level of the food pyramid.
In this scenario, we can reasonably infer and logically deduce that the value which best represents the amount of energy available for primary consumers in the food chain is 93,000 kilocalories.

Of the three types of subatomic particles, only neutrons do not carry charge. Protons carry a positive charge, and electrons carry a negative charge. Protons and neutrons are bound in the nucleus, while electrons orbit the nucleus. When the number of each type of subatomic particle in an atom changes, the characteristics defining the atom also change. Match the appropriate phrases with the type of subatomic particle that completes the defining characteristic.
Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer.
1. The number of ______ identifies whether an atom carries a charge as an ion or is neutral.
2. The number of ______ identifies the type of element.

What is a scientific investigation?A plan for raising questions and putting potential solutions to the test is scientific research. Observations are frequently the first step in scientific research. Questions frequently follow observations.
A hypothesis is a potential explanation for a scientific question based on current scientific understanding.
Making conjectures (hypothetical explanations) is a step in the scientific method. Predictions are then derived from the hypotheses as logical conclusions, and experiments or actual observations are conducted based on those predictions.
Therefore, the correct option is D. this ensures that all variables have full reliability and validity.

Due to changes in the tax structure and stagnant wages over the past fifty years, the income inequalities between the top and lowest earnings in the United States have significantly widened.
What is meant by the income gap?
An income gap is a term used to describe the disparity in income between demographic groups. The average income shortfall of families or people with incomes below the poverty line, represented as a percentage of the poverty line.
Numerous factors contribute to income inequality, such as historical racial segregation, political policies, a stagnant minimum wage, outsourcing, globalization, technological advancements, and the declining influence of labor unions.
What is the income inequality gap in the United States?
The wealth of the United States was owned by the wealthiest 10% of citizens in 2021, up from roughly 61 percent at the end of 1989. Over that time, the share held by the bottom 40 percent decreased proportionally. In 2021, the bottom 50% of the population, or around 63 million families, possessed 2.5% of the total wealth.

name at least two erroneous ideas about weightlifting that persist to the present day, and explain why they are in error
Answer:
Let understand that "Weightlifting" is a section of sport which involves individuals lifting heavy weight from the floor to shoulder position, back position and so on.
In essence, Weightlifting are used to build muscle and strengthens the bones & joints but also, the idea are passed as sport to see the ability of sportsmen in lifting heavy weight.
Some of the erroneous ideas about weightlifting are:
Lifting weights leads to bulking up: This idea is false and bulking up of muscles is determined by intake of calories to build the muscle internally. Weightlifting only make the muscles firm.
That weightlifting is bad for the joints: This idea is erroneous and not can not be proved. This exercise aids increased range of motion of the joint and thus ensure flexibility.

(First image) The Bohr model accounted for most of the general characteristics of the atom. However, the modern model based on quantum mechanics explains that, although the energy of each orbital is fixed, the orbital radius is actually an average distance. The result is a "cloud" where the electron would most probably be located.
When electrons are excited to different energy levels, the average radii from the nucleus also changes. Rank the following electron energy states according to the average distance of the electron from the nucleus. Rank from largest to smallest distances.

The atom consists of three types of subatomic particles: protons, neutrons, and electrons. The electron is by far the lightest of the three, while the much heavier proton and neutron have masses very similar to each other. Two of the types of particles carry an electrical charge, while the third is neutral. Label the subatomic particles and appropriate charges by their relative locations.
Identify the subatomic particles by dragging the appropriate labels to their respective targets.
Do you think government should provide easily accessible loans to students? What are some of the secondary effects of doing so?
Answer:
Below
Explanation:
If the government were to provide easily accessible loans to students, then there would likely be more students going to college, which would be a good thing because we would have a more educated society and workforce. However, taxes would have to be raised in order for people to receive these loans. There also would be a high percentage of the population in debt. Those would be the secondary effects.

Shown following are the primary mirror arrangements and total light-collecting area of five different telescopes. Each mirror uses a different segmented arrangement, but assume that they are all equivalent in quality and in their ability to focus light. Also assume that the telescopes use identical detectors and have the same observing conditions. Rank the telescopes from left to right based on their ability to detect very dim objects, from greatest to least. To rank two (or more) telescopes as equal, drag one on top of the other(s).
