Three species of frogs—Lithobates pipiens, Lithobates clamitans, and Lithobates sylvatica—all mate in the same ponds, but they p
Sladkaya [172]

Answer:

"This is a specific example of a reproductive barrier, called behavioral isolation or sexual isolation".

Explanation:

Reproductive barriers are <em>isolation mechanisms</em> that prevent mating between two or more species. The <u><em>prezygotic mechanism</em></u> avoids fertilization between individuals of different species, and the <u><em>postzygotic mechanism</em></u> avoids the zygote to develop and reach the adult stage.

There are different types of reproductive barriers, one of them is <em>behavioral isolation</em>, also known as <em>ethological isolation</em> or <em>sexual isolation</em>. This is a <em>prezygotic barrier</em> that refers to the fact that <em>many species occupy the same area</em> but they are <em>not sexually attracted</em> to each other and might even be rejected <em>because of behavioral factors</em>, and this is why they do not get to mate. This mechanism includes courtship patterns or mating rituals, and specific chemical signals that allow the recognition between individuals of the same species. A typical <em>example</em> is the <em>recognition songs</em> of some species like frogs, birds, insects, and etcetera.

Cytosine guanine thymine and adenine are referred to as phosphates. True or False
Harman [31]

Answer:

False

Explanation:

Cytosine, guanine, thymine, and adenine are collectively referred to as nitrogenous bases. These are not phosphates. The cytosine, guanine, thymine, and adenine are the four different types of nitrogenous bases. These nitrogenous bases are present in the deoxyribonucleotides. Cytosine and thymine are smaller in structure and have single ring structures. These are collectively called pyrimidines. On the other hand, adenine and guanine are the larger nitrogenous bases each with double ring structures. They are collectively called purines
