What are some of the challenges with using solar energy?
Answer:
A chanllenge can be that it's very pricy
Answer:
Some problems using solar energy are that it may not be a very reliable source because if you have an emergency in te middle of the night and need t charge your solar charged flashlight, you can't because it's nighttime. Solar panels are also not the prettiest thing and huge amounts of them can still mae very little power. Solar panels are also very expensive to install. On top of that, some communities don't want you using solar panels due to the bulky and blinding look of them.

What best explains the relationship between structure and function of the cell membrane?
Answer: The lipids and proteins that make up the membrane allow it to be selective about what enters and leaves the cell. The fluid inside the membrane buffers the chemical reactions taking place inside the cell.
Explanation:
Human red blood cells contain an important protein called?
Answer:
Explanation:
Red cells contain a special protein called hemoglobin, which helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs so it can be exhaled. Blood appears red because of the large number of red blood cells, which get their color from the hemoglobin.

Which statements represent convection? Select two options. Black asphalt gets very hot on a sunny day. The movement of air in a hot-air balloon makes it rise into the sky. A dark sand beach can burn the soles of your feet. A spoon gets warm from sitting in a soup pot. A house has high heating bills because the heat ends up in the attic. A house loses heat through an exterior wall.
Answer:
B. and E. are the correct answer because convection is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Explanation:
hope this helps
Convection is a heating transmission process. The options are B) The movement of air in a hot-air balloon makes it rise into the sky, and E) A house has high heating bills because the heat ends up in the attic.
What is convection?Convection is a natural process that results from heating transmission between two substances.
The change in temperature between these substances produces a change in density as well, and hence, the movement of the substances.
The cyclic circular ascending and descending motion of materials as they get heated or cooled is known as convective currents.
Among the options, the correct statements are,
B) The movement of air in a hot-air balloon makes it rise into the sky.
E) A house has high heating bills because the heat ends up in the attic.

Why must you avoid breathing or coughing on an agar plate?
Answer:
Explanation:
An agar plate is simply a Petri dish and it contains agar as a solid growth medium. It also contains nutrients for the culturing of microorganisms. Because of this reason, we must avoid breathing and coughing on these agar plates to avoid contaminating them. If they get contaminated we won't only see microorganism growth that we want to see for the experiment or test but also all the organisms from our body.

What happens when a light wave hits a translucent object, in terms of energy?
1) some of the energy is transmitted, whilst the rest is absorbed and reflected
2) most of the energy is transmitted
3) all energy is reflected
4) all energy absorbed
Answer:
1) some of the energy is transmitted, whilst the rest is absorbed and reflected
Explanation:
"When light strikes translucent materials, only some of the light passes through them. The light does not pass directly through the materials. ... Opaque objects block light from traveling through them. Most of the light is either reflected by the object or absorbed and converted to thermal energy."

Relate the law of conservation of mass to photosynthesis
The Law of Conservation of Mass holds true in photosynthesis
because the number of ______________
Answer:
moles of reactants is the same as the number of moles of products
Explanation:
Photosynthesis is the process whereby green plants manufacture their food in the presence of sunlight and water using energy from the sun. It is chemically symbolized as;
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
In the reaction above, the number of moles are balanced so as to comply with law of conservation of mass.
The law of conservation of mass states that "matter is neither created nor destroyed in the course of a chemical reaction but are simply transformed from one form to another".

calculate the mass of 0.35 mole of copper (||) sulfate (CuSO4).
The mass of 0.35 mole of copper (||) sulfate (CuSO4) is found to be 55.86 g.
What is the mass of any substance?The mass of any substance may be defined as a measure of the amount of matter in that particular substance. It is usually measured in grams (g) or kilograms (kg). Mass measures the quantity of matter regardless of both its location in the universe and the gravitational force applied to it.
According to the question,
The mole of copper (||) sulfate (CuSO4) = 0.35 mole.
The molar mass of copper (||) sulfate (CuSO4) = 159.60.
∴ The mass of any substance is calculated by the given formula:
Molar mass × No. of moles.159.60 × 0.35 = 55.86 g.
Therefore, the mass of 0.35 mole of copper (||) sulfate (CuSO4) is found to be 55.86 g.

Four cats are sitting in a living room. Which cat has the greatest gravitational potential energy? (Lesson 3.10 Gravitational Potential Energy) O A 15 lb cat sitting 3 feet off the ground in a window O A 15 lb cat sitting 1 foot off the ground on a box O A 10 lb cat sitting 1 foot off the ground on a box O A 10 lb cat sitting 3 feet off the floor in a window
Answer
I believe it is "A 15 lb. cat sitting 3 feet of the ground in the window"
Explanation:
I think it is this one because it is one off the heaviest cats and it is this one because this 15 pound cat is higher than the other one. I hope you get an A
The cat that has the greatest gravitational potential energy is A. A 15 lb cat sitting 3 feet off the ground in a window.
Gravitational potential energy refers to the energy that is possessed by an object due to its position on the gravitational field.
Gravitational potential energy is also referred to as the potential energy that an object has in relation to a different object due to gravity. Therefore, the greatest gravitational potential energy will be the 15 lb cat sitting 3 feet off the ground in a window.
