Two frog populations (same species) living in two neighboring lakes sing slightly different courtship songs. Increased irrigatio
dedylja [7]

Answer:

C. The songs will become more similar to each other.

Explanation:

To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.

One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.

So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.

The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.

Whole-genome sequencing can be used for advances in:
Mariana [72]

Answer:

all of the above

Explanation:

When the human genome was sequenced, one of the first information generated was related to the structure of the genetic material. For example, it has been found that there are long repeated sequences in different parts of the DNA or regulatory parts of its functioning in other parts of the genetic material itself.

When determining the order of nucleotides of a living being and comparing it with others of the same species, we find some regions that accumulate more differences than others, that is, are more diverse than others. Very similar sequences, that is, conserved in all living beings of the same species, can determine essential characteristics of these organisms. These essential characteristics can be very important for many different sectors and improve the lives of humanity in unimaginable ways.

The discoveries made through the complete sequencing of a genome can cause immense improvements in the fields of medicine, agriculture, biofuels and many other fields.

amm1812

Any specimen that is not handled properly may result in erroneous test results due to variables at pre-examination phase of laboratory testing.

A laboratory is a place where experiments and researches are performed. These scientific laboratories have a set of rules and protocols that are essential to follow to obtain the perfect results. A laboratory can be at school level, university level or even at industrial levels.

A specimen is defined as as the substance that is studied in the laboratory to obtain certain results or to make a new discovery. In biology, specimens can be living or dead organisms, cells, tissues, fluids, etc.
