We must first define these three prominent definitions of species. Biological species concept means that organisms resemble each other because of genes being passed from parent to offspring. Phylogenetic species concept means that organisms resemble each other because they evolved from a common ancestor. Lastly, morphological species concept characterizes species on the structure of their body parts rather than genetic or phylogeny.
In this case, (1) biological species concept is not applicable for extinct species, (2) phylogenetic species concept is based on evolutionary history, (3) morphological species concept relies on similarities in structure, (4) Morphological and phylogenetic species concept accommodates asexual reproduction, and lastly (5) all species concepts are used by scientists in classification.
The characteristic best distinguishes glycolysis and the Krebs cycle from the electron transport chain is the amount of ATP produced . In glycolysis net ATp production is 2 ATP and in 1 Kreb's cycle 38 ATP are produced. Hence option A is correct.
Answer:
A malaria outbreak causing allele frequencies to change is an example of <u><em>natural selection.</em></u>
Explanation:
Natural selection is a type of selection in which those organisms are favoured to live and reproduce which are better adapted to live in an environment. Due to natural selection, the allele frequencies of a population will tend to change with the passage of time.
When the outbreak of malaria occurs, those organisms which do not catch malaria are able to survive and pass on their characteristics to their offsprings. the other organisms die and do not reproduce. This will cause changes in the allele frequencies.
The answer is; Beads of different color joined together on a piece of string
Primary structure of a protein is right after it has been translated from an mRNA by a ribosome. It is linear and has not yet been folded into a functional protein. The beads in the item represent amino acids joined together by peptide bonds.
They cool too quickly to form crystal.
