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.

Explanation:
Chicken egg is biotic.
What are biotic or abiotic components?
Biotic components are living organisms while abiotic components are nonliving organisms. All biotic components are living components of ecosystem. Bacteria and birds, animals are living components.
Abiotic components are non living components. sunlight, water and temperature are the non living components. Biotic factors are producers, herbivores and omnivores.
Abiotic components are physical and chemical components that act on the living components. In chicken cell the yolk which is living cells.
Biotic components also include the waste from living things and dead organisms. Earth have many biotic components. The surface of Mars has no biotic components.

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
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.

You want to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%). How much of each will he have to mix together? Show your work for full credit.
Answer:
To make a 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%), 0.6 tons of soybean meal and 0.4 tons of corn are needed
Explanation:
Using the Pearson’s Square calculations:
1. Subtract across the diagonal:
a. 18% - 12% = 6 parts soybean meal
b. 18% - 22% = 4 parts corn
2. Sum the parts:
a. 6 parts soybean meal + 4 parts corn = 10 totalparts
3. Divide each part by the total to calculate the percentage of each feed to include in the ration:
a. 6 parts soybean meal ÷ 10 total parts * 100 = 60.0% soybean meal
b. 4 parts corn ÷ 10 total parts * 100 = 40.0% corn
So, to make 1 ton ration of an 18% protein ration using corn (12%) and soybean meal (22%),
60% of soybean meal is needed = 60/100 * 1 ton = 0.6 tons of soybean meal
40% of corn is needed = 40/100 * 1 ton = 0.4 tons of corn
What absorbs water in the digestive system
Your answer is Small Intestine.
Your small intestine makes digestive juice, which mixes with bile and pancreatic juice to complete the breakdown of proteins, carbohydrates, and fats. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.
