Nebulae are different luminous regions of the interstellar medium that can be made up of cosmic dust as well as ionized, neutral, or molecular hydrogen, hence option C is correct.

What is dust?

All the stuff between stars is referred to as interstellar matter by astronomers, and the complete collection of interstellar matter is referred to as the interstellar medium (ISM). Some interstellar material is gathered into massive clouds that are each referred to as a nebula.

Tiny pieces of solid matter drifting about in the region between stars make up cosmic dust. It's not like the dust you find in your home; instead, it has tiny particles that range in size from collections of just a few molecules to grains that are 0.1 mm in size.

Therefore, an interstellar medium can be made up of cosmic dust as well as ionized, neutral, or molecular hydrogen, hence option C is correct.

A stone 'X' of mass 2 kg is at the height of 2 m from the ground level
Another similar stone 'Y' of mass 4 kg is at the height of 4 m from the ground
level. What is the difference between their potential energy?
un minutes Calculate​

Answers

Answer:

120 joule.

Explanation:

Given

For the stone X

Mass (m) = 2 kg

Height (h) = 2 m

Acceleration due to gravity (g) = 10 m/s²

Then we have the formula to calculate the potential energy

P.E 1 = mgh

= 2 * 10*2

= 40 joule

Now for Stone Y

mass (m) = 4 kg

height (h) = 4 m

acceleration due to gravity (g) = 10 m/s²

Now

P. E2 = mgh

= 4 * 10* 4

= 160 joule

Now the difference between their potential energy is

= P. E2 - P. E 1

= 160-40

= 120 joule

Hope it will help you :)

What molecule do organisms obtain energy from

DNA
ADP
Sugar
ATP
All the above.

Answers

Organisms mainly use the molecules glucose and ATP for energy. Glucose is a compact, stable form of energy that is carried in the blood and taken up by cells. ATP contains less energy and is used to power cell processes. The flow of energy through living things begins with photosynthesis, which creates glucose.
Answer:
ATP

Explanation: as the other person said they mainly use glucose or ATP for energy. Adenosine triphosphate (ATP) is the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.

What is osmoregulation?

Answers

Answer:

adalah penghijauwan kota

Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated. Osmotic pressure is a measure of the tendency of water to move into one solution from another by osmosis.[1] The higher the osmotic pressure of a solution, the more water tends to move into it. Pressure must be exerted on the hypertonic side of a selectively permeable membrane to prevent diffusion of water by osmosis from the side containing pure water.

Organisms in aquatic and terrestrial environments must maintain the right concentration of solutes and amount of water in their body fluids; this involves excretion (getting rid of metabolic nitrogen wastes and other substances such as hormones that would be toxic if allowed to accumulate in the blood) through organs such as the skin and the kidneys.

Which of the following processes cycles matter through different parts of an ecosystem?
More than one answer may be correct.
1. the nitrogen cycle
2. the water cycle
3. the carbon cycle

Answers

Answer:

the nitrogen cycle, the water cycle, and the carbon cycle

Explanation:

The water, carbon, and nitrogen cycles move nutrients through the different parts of an ecosystem. Water moves through organisms and the environment in different phases. Carbon moves through an ecosystem in carbon dioxide, minerals, and organic compounds. Nitrogen moves through an ecosystem in nitrogen gas, ammonium, nitrates, and organic compounds.

The biogeochemical cycle is a pathway that circulates the chemicals through the abiotic and the biotic factor. The nitrogen, water, and carbon cycle through various regions of an ecosystem.

What is a biogeochemical cycle?

The biogeochemical cycle is the movement of the chemicals and compounds of carbon, nitrogen, and water in the biosphere (biotic) and the atmosphere, lithosphere, and hydrosphere (abiotic) spheres of the earth.

These cycles move the nutrient through different spheres in the form of inorganic and organic compounds. It is an essential part of the ecosystem as they regulate the flow of the natural elements.

Therefore, option 1. nitrogen cycle, option 2. water cycle, and option 3. carbon cycle move through various parts of an ecosystem.

What type of energy has to do with a change in temperature?

Answers

Answer: changes in heat energy change temperature

Explanation: heat energy can be thought of as energy in individual atoms or molecules, which vibrate more as energy increases. Temperature is a measure of heat energy. For example, many substances expand as heat energy causes it atoms/molecules to vibrate more and occupy more space. We can use this property to measure energy as temperature by using the expansion of a liquid as in thermonmeters.
