The correct answer is D. Abstinence

Explanation:

A contraceptive method or birth control method refers to a method used to avoid pregnancy or reduce the probability of getting pregnant. From antiquity, there have been different contraceptive methods but only in the last decades, methods have been designed based on science and its effectiveness has been studied.

Because of this, nowadays there are many contraceptive methods such as pills, condom, and implants that are about 80% to 95% effective, sterilization that is a around 98% effective and natural methods that have a lower percentage of effectiveness. But the only method that has been proven as completely effective or 100% effective is abstinence because by avoiding any type of sexual intercourse it is virtually impossible an egg can be fertilized by a spermatozoid.

Biology &amp; Behavior: Evolution &amp; Genetics<br> Why people behave the way they do?
xxTIMURxx [149]

People behave the way they do because of situation as well as genetics.

<h3>Why people behave the way they do?</h3>

People behave as they do in response to the way they are treated by other people as well as in response to situation. In their behaviour, they have also a genetic factor that influence their behaviour.

So we can conclude that people behave the way they do because of situation as well as genetics.

Electron microscopes use
Pavel [41]

Electron microscopes use _beam of electrons___ in order to allow for higher magnification and more detail when viewing specimens.

Explanation:

A beam of electrons has a shorter wavelength than normal light used in light microscopes, by approximately a factor of X 100000. Therefore, electrons microscope have the inherent attribute of having a very high resolution. They have been used to discover very small organelles in cells such as the ribosomes and mitochondria that cannot be clearly viewed even with the highest resolution in light microscopes.

3. How does fluoroquinolone affect bacterial cells but not eukaryotic cells?
Valentin [98]

Answer:

In order to be useful in treating human infections, antibiotics must selectively target bacteria for eradication and not the cells of its human host. Indeed, modern antibiotics act either on processes that are unique to bacteria--such as the synthesis of cell walls or folic acid--or on bacterium-specific targets within processes that are common to both bacterium and human cells, including protein or DNA replication. Following are some examples.

Most bacteria produce a cell wall that is composed partly of a macromolecule called peptidoglycan, itself made up of amino sugars and short peptides. Human cells do not make or need peptidoglycan. Penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium. No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us.
