Mars is known as the ____ planet.
A) Blue
B) Gaseous
C) Red
D) Sandy
Answer:
Of course it's C
Red planet
Explanation:
It is because the soil on Mars is rich of Fe (Iron).
That makes the soil look red.
Even on our planet we have such this places like hormuz island in Iran.
Usable forms of nitrogen can intentionally be increased in the soil by(1 point)
lightning.
planting more trees.
allowing organic matter to decompose.
planting fewer beans.
Usable forms of nitrogen can intentionally be increased in the soil by allowing organic matter to decompose. Therefore, option C is correct.
What is organic matter ?Organic matter is defined as anything that contains carbon compounds formed by living organisms. It includes lawn clippings, leaves, stems, branches, moss, algae, lichens, animal parts, manure, droppings, sewage sludge, sawdust, insects, earthworms, and microbes.
The majority of organic matter in soil comes from plant tissue. Plant residues have a moisture content of 60-90 percent. Carbon (C), oxygen, hydrogen (H), and trace amounts of sulphur (S), nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and magnesium make up the remaining dry matter (Mg).
Microorganisms such as bacteria, viruses, fungi, protozoa, and algae are among the living components of soil organic matter. Plant roots, insects, earthworms, and larger animals such as moles, mice, and rabbits are also included.
Thus, option C is correct.

magnesium reacts with oxygen and forms magnesium oxide , for example
Answer: When the magnesium metal burns it reacts with oxygen found in the air to form Magnesium Oxide, which is a compound. ... After it burns, it forms a white powder of the magnesium oxide. Magnesium gives up two electrons to oxygen atoms to form this powdery product. This is an exothermic reaction.

5. When a copper metal is exposed to moist air for a long time,then a green coating is formed on its surface .What is the green material formed on its surface. Support your answer with word equation.Is it acidic or basic in nature.
PLEASE HELP ME !!!!
Answer:
A. oxygen
B. chlorine
2. iodine
(a) because aluminium is a soft malleable metal. it can be made to in sheets to form thin wrapping sheets. also, it does not react with food items.
(b) because metals are good conductors of heat and electricity. the immersion rod needs electric supply to get heated and to heat liquids.
(c) they're kept in kerosene to keep them from coming in contact with oxygen and moisture as they react to form their hydroxides.
4. Magnesium is a metal. Metals react with oxygen to form metallic oxides. So Magnesium oxides are basic in nature. But nonmetals react with oxygen to form nonmetallic oxides. These oxides differ from metallic oxides because they are acidic in nature. Nonmetallic oxides react with water to form acids. Therefore, Sulphur dioxide is acidic in nature. Magnesium oxide is basic in nature.
5. Copper forms a green deposit on its surface when exposed to air which is usually a mixture of copper carbonate and copper hydroxide. It's acidic in nature.

What is the structure labeled with an arrow?
A. Cytoplasm
B. Nucleus
C. Cell wall
D. Flagellum
In the given diagram, the structure labeled with an arrow is the nucleus. Therefore, option (B) is correct.
What is the nucleus of a cell?The nucleus is the most integral component of the cell. A nucleus can be defined as a double-membraned eukaryotic cell organelle that consists of genetic material.
The nucleus is typically the most evident organelle in the cell. The nucleus is entirely bound by membranes and is surrounded by the nuclear envelope.
The contents of the nucleus distinguish from the cytoplasm by the membrane. The nucleus contains hereditary information about the cell and controls its growth and reproduction.
The nucleus is not just a storage section for DNA but also occurs to be the home of cellular processes. In the nucleus, DNA can be duplicated and the process is named as named DNA Replication and produce an identical copy of the DNA.
In the diagram, the arrow indicates the nucleus.

A student asks a class the following question, “Polyethylene has a relatively short formula (C2H4) while nylon has a long formula (C12H22N2O2). However, in a toothbrush, the handle is relatively long while the bristles are relatively short. How is this possible?”
Choose the explanation below that best responds to the student’s question.
A
Molecules are so small that they cannot be seen with a naked eye. Therefore, being a slightly bigger molecule on that scale will not influence how big the part of the toothbrush is.
B
In a toothbrush, the polyethylene chain is most likely a longer chain of molecules than the nylon chain, making the handle longer than the bristles.
C
Polyethylene is used for the bristles and nylon is used for the handle, because the size of the molecule does determine the size of the object being built by the molecules.
D
Polyethylene has a short formula, but it makes a long chain. Nylon has a long formula, but it is fat, not long. That is why the nylon bristles are short while the handle is long and thin.
