IrinaK [193]

Answer:

functional groups

Explanation:

Functional groups are molecules with specific atoms and have their own chemical properties when attached to some other substances. Glucose is a simple sugar and has an aldehyde group (CHO) as its functional group. The presence of CHO in it makes it be present in food without any harmful impacts. On the other hand, hexanoic acid has COOH (carboxylic group) as its functional group. COOH group has a tendency to donate its protons and become ionized. It is toxic as it is reactive and tends to affect the pH of the food or solution in which it is present.

According to biochemist sidney fox, once amino acids formed in the oceans, they may have collected in small pools to form small
Blizzard [7]

Formed tiny polypeptides known as Proteinoids when they gathered in little pools.

<h3>What is a polypeptide and how does it work?</h3>

Polypeptides. By joining many amino acids together, polypeptides contribute to the creation of proteins. When two or more polypeptides are joined together to form a protein, the resulting structure is unique to that protein.

<h3>What conclusions did Sidney Fox's experiment reach?</h3>

In the 1950s, Sidney Fox demonstrated that when amino acids were splashed in hot, dry circumstances, they immediately polymerized into proteins. Other studies that used cyanide, clays, and heat to cause the polymerization of amino acids into proteins were effective.

Which of the following environments would not contain fossils
juin [17]

Answer:

as I know

Explanation:

<em>Igneous rocks, which form from cooling magma or lava, and metamorphic rocks, which have been altered by heat and pressure, are unlikely to contain fossils. The “soft” tissues of an organism, such as skin, muscles, and internal organs are typically not preserved as fossils.</em>

State the five requirements for a population to be in Hardy-Weinberg equilibrium.
mihalych1998 [28]

When it comes to population evolution and genetics, we cannot fail to cite the Hardy-Weinberg principle which emphasizes that if evolutionary factors such as natural selection, mutation, migration and genetic oscillation do not act on a particular population, the frequencies genotypic proportions will remain constant.

The five requirements for a population to be in Hardy-Weinberg equilibrium are:

  • Large-scale breeding population: For a population to be in Hardy-Weinberg equilibrium, it is important that this population is large, as small populations favor genetic drift (unanticipated fluctuations in allele frequencies from one generation to another).
  • Random mating: In order for the Hardy-Weinberg equilibrium to occur, it is necessary that the mating occur at random, with no preference for certain groups within the population. In this case, we say that the population is in panmixia, that is, they all mate at random.
  • No mutations: Mutations alter the total alleles present in a population (gene pool). Therefore, in a Hardy-Weinberg equilibrium population, no mutations should occur.
  • No gene flow: When there is gene flow due to migration or immigration of individuals, some genes may be included or excluded from the population. Thus, in an equilibrium situation, no gene flow occurs.
  • Lack of natural selection: For a population to be in Hardy-Weinberg equilibrium, natural selection must not be acting on it. If natural selection acts, some genotypes will be selected, modifying the allelic frequencies of the population.
