Answer: B) Recycle resources more frequently

Minerals are naturally occurring chemical compounds, these are non- renewable resources. These can be found in the rock mass develop by physical process inside the earth crust due to changes in temperature and pressure. Due to increase in population cover all over the world, the minerals are becoming scarce.

Recycling is a process in which the used resources are transformed or converted in a form so, that it can be used again or may degrade the resource completely, so that it does not contaminate the environment. With the recycling process many minerals like metals can be recycled so that they can be used again. Hence, ensures sustainable use of minerals, and making them available for future generation.

A total of _____ amino acids compose the majority of protein in living things and nine are _____ to human

Evgen [1.6K]

A total of 20 amino acids compose the majority of protein in living things and nine are essential to human.

All living organisms, from bacteria to people, depend on amino acids for survival.
The same 20 types of amino acids are present in all living things.
Only 21 amino acids are required by the human body to create all the proteins required for growth and function.
Your body can create thousands of different types of proteins with only the same 21 amino acids because they can be ordered in a wide variety of ways.
The body is unable to produce essential amino acids. They must therefore originate from food.
Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.

aliina [53]

Answer:

Genetic drift

Explanation:

Genetic drift can also be referred to as allelic drift, it refers to the variation in allelic frequencies within a particular population over a period of time. It can also be referred to as the random fluctuations in the number of genotypes within a population. Genetic drift is not influenced by the environment and is usually more pronounced in a small population of organisms.

For example, a population of birds can consist of green feathers and blue feathers with the green feathers as the dominant allele, but as a result of random fluctuations, the offspring may all be with green feathers and hence could eliminate or reduce the allele responsible for blue feathers over time.

What two compounds are the waste products of cellular respiration? * H2O and CO2 H2O and C6H12O6 CO2 and C6H12O6 ATP and CO2

rusak2 [61]

Answer:

The two compounds that correspond to waste products of cellular respiration are H₂O and CO₂.

Explanation:

The cellular metabolic waste products, specifically from cellular respiration are water (H₂O) and carbon dioxide (CO₂), from the oxidation of glucose into energy.

The process of cellular respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions where, from a glucose molecule, energy is obtained in the form of ATP molecules.

Obtaining H₂O and CO₂ from glucose can be summarized with the schematic reaction:

C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂

This summary indicates that a glucose molecule, when oxidized, produces as waste 6 molecules of water and 6 molecules of carbon dioxide. To reach this process all the reactions of the oxidative phosphorylation occur and 24 molecules of ATP are obtained for each molecule of glucose.

For the other options it is important to mention that:

C₆H₁₂O₆ is the substrate from which cellular respiration takes place.
ATP is the final product of cellular respiration, translated into energy to be used by the cell.
