Which line-angle formula represents an alkene?

Answer:

Option 3.

Explanation:

Alkenes are generally unsaturated hydrocarbon with carbon to carbon double bond (C=C).

From the options given above, only option 2 and 3 contain carbon to carbon double bond (C=C).

Option 2 is called a benzene ring and not an alkene. Benzene are not classified as alkenes because the double bond between the carbon can not be broken i.e benzene does not undergo addition reaction like the alkenes. Benzene tends to show more stability than the alkenes.

This leaves us with option 3 as the answer to the question because it contains carbon to carbon double bond (C=C)

Scenario:Fossils show that many species, or kinds of organisms, have died out or become extinct because they could not respond to the pressures fast enough to survive. Those that did survive were better suited to their environment. Evidence shows that new species develop from old species as a result of gradual change. Natural selection is one process by which organisms change over time. Evidence shows that species change over time, sometimes giving rise to new species.External DataPrompt:Look at the pictures above that show how the giraffe got such a long neck. Write a scientific explanation of how natural selection applies to this process.

Scientists have discovered a colony of potential organisms on the Planet Moby and named them "Maxoids." Read the information below that scientists have gathered on Maxoids and decide whether Maxoids are living or nonliving things. Explain how you came to this conclusion.

Through testing and observation, scientists have recorded the following characteristics of Maxoids. Maxoids reproduce via sexual reproduction. One parent carries the Maxoid eggs for 12 weeks before they hatch. After hatching, juvenile Maxoids continue to grow for seven months. To acquire energy for growth, Maxoids consume a peculiar liquid substance native to the planet Moby. The Maxoids' cells use this energy, as well as large amounts of water, to carry out important functions. The Maxoids are sensitive to changes in internal temperature. Sometimes they dig holes and lay in them to cool down if they get too warm.
