By elimination: d is wrong for sure.
c is not right as there is no gland in the esophagus or the pharynx
b is also wrong as if there is no gland, then there is no enzyme and no chemical digestion in <span>esophagus or pharynx
a is the only one left.</span>
<span>The prescription should be an intravenous line into the patient. The reason for this is that Grey Turner's can cause a bluish color to be seen in the patient's upper abdominal area as well as the lower back. This is known as the 'flank area'. This pain is caused by bleeding. The intravenous line will give a replacement in terms of volume.</span>
<h3><u>Answer;</u></h3>
B. Her claim is correct because changing the DNA sequence will alter the amino acid sequence that codes for traits.
<h3><u>Explanation</u>;</h3>
- <em><u>Genetic mutations caused by the insertion or deletion of one or more nucleotides causes a change in the amino acid sequence from the site of the mutation forward.</u></em>
- Insertions and deletions results to frame-shift mutations when base pairs that are not a multiple of three are added to or deleted from the sequence.<u>This type of gene mutation alters the template from which amino acids are read, it thus alters the amino acid sequence that codes for characteristics shown by an organism.</u>
Answer:
There are no electrons in the atom.
Explanation:
The electron is a subatomic particle, symbol e⁻ or β⁻ , whose electric charge is negative one elementary charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.
Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.
Answer:
The bacterium Vibrio cholerae is the primary cause of cholera disease that mainly infects the small intestine and primarily leads to the dehydration of the body.
Explanation:
The genetic analysis reveals that the aforementioned causative bacteria surpass the acidic conditions of the stomach and eventually reaches the intestinal wall and attaches to it. This is followed by the production of toxic protein by the bacterium. This protein is taken inside the cell via receptor mediated endocytosis followed by its binding to the host protein Arf6. This binding leads to the production of cAMP that results in the dehydration process. This mechanism leads to excessive accumulation of chloride ion in the intestine preventing the entry of sodium ion.
These two ions are associated with the creation of water-salt environment in the intestine that leads to tremendous diarrhea via the process of osmosis.
Hence, we can say that cholera bacterium affects the individuals at the cellular level and osmosis plays a vital role in the process.
