What part did you need help understanding? Your definition is pretty strong- the epiglottis keeps food from entering the trachea and lungs. It also opens during breathing to allow air into the lungs. Good luck on your test, let me know if you need anymore refreshers!
Answer:
<em>B. Methyl yellow, which changes from yellow to red around a pH of
</em>
<em>4.0</em>
Explanation:
A pH indicator is a technique by which the pH of a solution can be known. The scenario in the question describes that the scientist wants to determine a pH after it gets converted from 6 to below 4. For this recognition, the scientist should use a methyl yellow indicator which will change from yellow to red once a pH around 4 is achieved.
Natural selection is the process through which species adapt to their environments
natural selection is the method through which populations of dwelling organisms and species adapt and exchange. individuals in a population are obviously variable, that means that they will be all unique in a few methods. this variation approach that some humans have trends higher suited to the environment than others. people with adaptive tendencies—traits that supply them a few advantage—are more likely to live to tell the tale and reproduce. those humans then pass the adaptive developments directly to their offspring. over the years, the ones powerful trends come to be more not unusual within the populace. through this machine of natural selection, favorable trends are transmitted through generations.
natural selection can cause speciation, in which one species offers rise to a brand new and rather precise species. it is one of the processes that drives evolution and permits to provide an cause of the sort of existence inside the world
Darwin selected the decision natural choice to contrast with “artificia selection,” or selective breeding that is controlled via human beings..

Answer:
It would have disastrous consequences on the viability of the individual
Explanation:
The genome can be defined as the genetic material of an organism, which is composed of DNA molecules named chromosomes whose building blocks are four different nucleotides: Adenine, Thymine, Cysotcine and Guanine. The order of these nucleotides specifies the information contained in the chromosomes and, ultimately, in the genome. The genes, which are recognized to be the basic units of inheritance, are genetic sequences composed of ordered nucleotides along the chromosomes. During transcription, a gene encodes different RNA codons (for example, start and stop codons) which are specified by the order of the nucleotide sequence. Finally, the order of the RNA codons will be critical to specify the polypeptide chain during the translation from RNA to protein.
The answer is : exponentially
