How can you account for the great number, size, and complexity of organic compounds?

Answers

Answer:

Explanation:

"how can you account for the great number, size, and complexity of organic compounds? carbon can bond with so many elements. It can bond with itself and form long chains. Also, all macromoleculse are composed of C,H,N, and O."

Organic compounds number in the millions, far outnumbering inorganic compounds. The reason for this is due to the uniqueness of carbon's structure and bonding abilities.

What are organic compounds?

Any of a wide range of chemical compounds in which one or more carbon atoms are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.

Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.

Organic compounds in the body include carbohydrates, lipids (including phospholipids), proteins, nucleotides, and nucleic acids.

Water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and some acids, bases, and salts are the most important inorganic compounds. The human body is 60-75% water.

Organic compounds outnumber inorganic compounds by orders of magnitude. This is because of the uniqueness of carbon's structure and bonding abilities.

Thus, this way, one can account for the great number, size, and complexity of organic compounds.

How do trees offset our carbon footprint? Put an x in each box that applies
Trees absorb carbon dioxide from The atmosphere and turn it into oxygen
Trees help limit the amount of greenhouse gasses in our atmosphere
Trees absorb oxygen from the atmosphere and turn it into carbon dioxide
Trees are great for shade

Answers

Answer:

Trees absorb carbon dioxide from the atmosphere and turn it into oxygen

Explanation:

Trees help to offset our carbon footprint by absorbing carbon dioxide from the atmosphere and turning it into oxygen.

Trees are often regarded as carbon sinks because they take in more carbon dioxide than they release.

The process of photosynthesis is one that allows plants to use carbon dioxide and water in the presence of sunlight to produce their own food. In this process, oxygen is the by-product.

The epicenter and hypocenter are two important points in causing earthquakes.

Both the epicenter and hypocenter are different from each other in the following basis:

Location: Hypocenter is present within the earth surface where an earthquake rupture starts and the epicenter is located in the earth's crust just above the hypocenter where a seismic rupture begins.

Associated waves: Seismic waves propagate from the hypocenter caused by seismic velocity and rock density which reaches the epicenter where P and S waves hit the surface of earth.

What is Symbiosis?

Symbiosis can be defined as a type of relationship or interaction between two different living organisms which share a similar habitat. There are three different types of behaviors that were observed in symbiotic relationships, namely mutualism, commensalism, and parasitism.

In this type of interaction, the organisms live in a close physical association with each other. In the case of symbiosis, both the organisms are benefitted from the interaction. This type of interaction provides an advantage to both the organisms. The common example of symbiosis is the Rhizobium bacterium species and the leguminous plants.
