essay on atoms molecules and matter

Answers

Answer:

Atoms are typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the center of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.

Molecules are groups of atoms clumped together by chemical bonds. They are also distinguished from ions by their lack of electrical charge.

H20 is a molecule, N2 is a molecule even O3 is a molecule.

Matter is basically anything that takes up space and that has mass. All physical objects have matter. The original stated of matter are solid, Liquid, And gas.

seeds

Answers

answer is seeds

when you hear angiosperms think fruit

Angiosperms reproduce using seeds. Therefore, option (D) is the correct answer.

What type of seeds do angiosperms have ?

Angiosperms are plants that blossom and produce fruits that contain their seeds. With around 300,000 species, they are the most numerous and diverse group within the kingdom Plantae. Approximately 80% of all known extant green plants are angiosperms.

Varied plants are angiosperms. They have leaves, stems, and roots. Angiosperm seeds are found in a flower, as opposed to gymnosperm seeds found in conifers and cycads. Angiosperm ovaries, which are typically found in flowers, are where fertilized angiosperm eggs turn into seeds.

An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone.

True

False

Answers

Answer:

The answer is true.. it is attached to the carbon backbone.

The statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.

What is Unsaturated fat?

Unsaturated fat may be defined as a kind of fat carrying a high proportion of fatty acid molecules with at least one double bond. This type of fatty acid is considered to be healthier in the diet than saturated fat.

An unsaturated fat generally contains almost all of the hydrogen atoms which are directly attached to the carbon backbone in a series of systematic arrangements.

Unsaturated fat is typically fatty acid that remains liquid at room temperature and comes from a plant, such as olive, peanut, corn, cottonseed, etc.

Therefore, the statement "An unsaturated fat has the maximum number of hydrogens attached to the carbon backbone" is definitely true.

Inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.

True

False

Answers

Answer:

[tex]{ \underline{ \sf{true}}}[/tex]

Explanation:

because they chemically decompose

It is true that inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.

What are inorganic compounds?

Any substance in which two or more chemical elements usually other than carbon are combined, almost always in definite proportions, is an inorganic compound.

When carbon is bound to hydrogen, the compound is classified as organic.

Organic compounds are distinguished by the presence of carbon atoms. Most inorganic compounds do not contain carbon atoms.

Water, sodium chloride (salt), sodium bicarbonate (baking soda), calcium carbonate (dietary calcium source), and muriatic acid are examples of common inorganic compounds (industrial-grade hydrochloric acid).

Inorganic compounds are characterized by high melting points and varying degrees of electrical conductivity.

Thus, the given statement is true.

Reactant+ Reactant= Product.

Glucose (Reactant)+ Oxygen (Reactant)= Carbon Dioxide (Product) and Water (Product) (C02)

Hope this helps!

The one that is a reactant during cellular respiration is Glucose. The correct option is B.

What is cellular respiration?

Cellular respiration is a process of breakdown of food material to produce energy that is then saved in the form of ATP. The process occurs when oxygen is combined with food and produces energy and reduces the waste material removed from the body.

The chemical process includes four processes that occur in sequence to carry out the whole process. The processes are glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

All food that we eat gives us different macromolecules, glucose is the main source of energy. So glucose is converted into energy.

Thus, the correct option is B. Glucose.
