Speciation, when populations evolve to become distinct species
Directional selection is a type of natural selection that favors one extreme phenotype over the mean or another extreme. Examples of directional selection include giraffes that have long necks and the darkening of London's peppered moths after the Industrial Revolution.
Stabilizing selection, also known as purifying selection, is a type of natural selection in which genetic diversity decreases as the population stabilizes on a particular trait value. An example of stabilizing selection is birth weigh in humans.
Disruptive selection is a type of natural selection that shows a preference toward the reproduction of genetic material at the extremes within a population.One of the most studied examples of disruptive selection is the case of London's peppered moths.

Answer:
That is the smooth endoplasmic reticulum.
Explanation:
You can tell because there are no ribosomes on it.
Answer:
Choosing protein as macromolecule.
Explanation:
The given environmental changes can lead to structural changes in protein as well:
pH - Several amino acids contain sidechains with practical gatherings that can promptly pick up or lose a proton. Changes in pH would prompt an adjustment in the charge of the amino acids, prompting charge-charge attraction or repilsion between non-interfacing amino parts.
Temperature - High temperatures can prompt protein denaturation. Warmth can upset hydrogen bonding and hydrophobic interactions.
Reduction or oxidation Environment - Some tertiary structure of protein folding is held by disulfide linkages. Reducing agent will lead to unfolding by introducing itself to break disulfide bonds.
Effect of these change: Sequence of amino acid and structure of protein molecule form determines function, any slight change to a protein's structure may result in the protein to become dysfunctional or produce different product.
Answer:
Insecta
Explanation:
The classification levels are the following from broadest to the most specific:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
In your selection it is listed in that order:
Domain --- Eukarya
Kingdom --- Animalia
Phylum --- Arthropoda
Class --- Insecta
Order --- Hymenoptera
Family --- Apidae
Genus --- Apis
Species --- Mellifera
When you name the organism, we use the two name or binary naming system, getting the genus and the species. So the scientific name of the honey bee is: Apis mellifera
