Answer:
Plants, animals, and fungus
Explanation:
A protist is an organism with eukaryotic cells that is not a(n) plant, animal, or fungus.
Answer:
Parasitic
Explanation:
The species that is described is a parasitic species. The reason why it will fall into this category is that its key feature is that it is entirely dependent on other organisms for its food. This type of species are not able to produce food for themselves, nor are able to get it from the environment, which is way they have evolved in a manner to use the other organisms. They find a host organisms, attach to it, and then they are extracting the nutrients out of that organism, thus classical parasitism. The extraction of the nutrients can be so severe that the parasitic species can actually kill systemically its host.
Answer:
The bell of the stethoscope is used during auscultation to listen for low pitched sounds typical of a heart murmur.
Explanation:
Auscultation is a diagnostic test that listens to sounds from the heart, lungs, bowels, the circulatory system and other parts of the human body.
The stethoscope is an instrument that is designed for auscultation.
The diaphragm of the stethoscope listens for high pitched sounds typical of the bowels, a normal heart, and breathing.
The bell of the stethoscope listens for low pitched sounds typical of a heart murmur.
Answer:
The organism closest to the coral snake is organism 3, followed by organism 1 and finally organism 2.
Explanation:
The more similar the DNA composition of the organisms, the closer and more closely related they are. With that we can say that the coral snake is closer to organism 3, since the sequence of nitrogenous bases in its DNA is more similar, in relation to other organisms. After organism 3, it is organism 1 that most resembles a coral snake. Organism 2, however, has a different DNA composition, the organism being less similar and the more distant from the coral snake.
Answer:
The correct answer is a and e.
Explanation:
Translation is the process by which mRNA is translated into proteins. It occurs in both prokaryotes and eukaryotes. In prokaryotes, transcription and translation occur simultaneously while in eukaryotes translation is a separate process occurs in the cytoplasm after transcription.
The first amino acid incorporated in the polypeptide is methionine in eukaryotes and formyl methionine in prokaryotes. After protein synthesis in both eukaryotes in prokaryotes, post-translational takes place like glycosylation, acetylation, alkylation, etc.
Post translation is important for proteins to provide them heterogeneity and functional activity. Thus, the correct answer is a. the first methionine in eukaryotic translation contains a formyl group and e. many eukaryotic proteins are chemically modified after translation, which is a much rarer phenomenon in prokaryotes.
