Biology

Vilka [71]3 years ago

Answer:

Polar

Explanation:

Polar is a concept which explains the formation of a particular molecule as a result of a separation of electric charges. In such molecule formed, there is a negatively charged end and a positively charged end. The difference in their electronegativity is what determines the strength of the bind formed in the molecule.

Electrically charges object can be used to attract molecules that are polar. This is because, when polar molecules are placed in an electric field, the positive charged end tends to align with the negative plate while the negatively charged end tends to align with the positive end.

Examples of polar molecules are water, hydrogen sulphide, ethanol, and some others.

Which of the following are NOT correct based on Darwin's theory of evolution?

Answer:

D variations in individuals are not heritable

Explanation:

Genetic variation in individuals is what drives evolution. In a population of individuals in an environment, with the adequate resources, overpopulation can occur. However, resources are usually a limiting factor for population growth: there is not sufficient food/shelter etc. for everyone to survive.

Some individuals are better suited to success in the environment. This is because of random variation in their DNA that has arisen that give them a selective advantage. This allows them to thrive, take advantage of the limited resources over other members of the population, and be more likely to survive to reproductive age. This is natural selection.

Because this variation is genetic (in the DNA), they can then pass it on to their offspring. Over time, this leads to evolution over time.
