Petrus brings his 87-year old grandmother to the emergency department where you work. His grandmother has a fever, is dehydrated and confused, and complains of pain when urinating. Petrus reports that she has not been eating or drinking, but she has no signs or symptoms of gastrointestinal distress. You request blood samples and also a urine sample. You decide to keep Petrus' grandmother in the hospital so that she can be given intravenous fluids. You also want to wait for the lab test results before you decide whether she required additional treatment or if she can return home.
1. When Petrus' grandmother's test results are sent to you, you discover that while her blood work is normal, her urine has Gram-negative bacilli in it. Based on this, you know that the cells are:______.
a) stained blue and are cylindrical in shape.
b) stained purple and are cylindrical in shape.
c) stained pink and are spherical in shape.
d) stained pink and are cylindrical in shape.
e) stained green and are oval in shape.
2. Petrus asks you what the Gram-negative result means and you explain that the bacteria causing his grandmother's UTI:____.
a) have a thin cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
c) have no cell wall but they have a thick outer membrane which makes the cells less sensitive to the antibiotic penicillin.
d) have a thin cell wall and an inner cell membrane which makes the cells less sensitive to penicillin.
e) have no cell wall which makes the cells more sensitive to the antibiotic penicillin.
Answer:
d) stained pink and are cylindrical in shape.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
Explanation:
Gram-negative bacteria are bacteria that do not retain the crystal violet stain. So they stain in pink and they have an outer cell membrane unlike gram positive bacteria.

Which is not a reason why organisms are classified into Domains and Kingdoms?
Answer:
for a better study of organisms
Explanation:
Organisms are classified into domains and kingdoms based on their cell type, their ability to make food, and the number of cells in their bodies.
Domains and kingdoms are the highest categories of classification. It is usually used to classify organisms to make it simple for their identification. It is not classified only to study the organism better.
What are domain and kingdom?A domain is the highest category of classification and a kingdom is a second-highest category.
Living things are placed in these categories according to their way of obtaining food, the number of cells, types of nuclei, etc.
It is used to avoid confusion between the organism and to show that the organisms are related to each other.
Thus, it can be concluded that it is not used not only study but for other purpose also.

The black panther phenotype in jaguars, which is a completely black coat, is thought to be determined by a single gene. If the presence of this phenotype were unrelated to habitat type, but was found to be much more common in populations in Costa Rica relative to populations in Brazil, what would be the most likely explanation for this geographic pattern
Answer:
Due to suitable climate and food availability.
Explanation:
The reason for this geographical distribution is the availability of suitable climate and food. Black panthers live in the hot, dense tropical rainforests environment where there is a lot of food present that is necessary for sustaining the population of black panthers. Black panthers are more common in Costa Rica as compared to populations in Brazil due to climate as well as food availability.
Which of the following statements is not true of the circulatory system and its transport of nutrients?
a. Water-soluble nutrients leave the small Intestine via lymph.
b. Nutrients that leave the small intestine via blood are delivered first to the liver.
c. Lymph empties into the blood just before the blood reaches the heart.
d. Lymph is formed from fluid that Is forced out of capillaries by blood pressure.
Answer: b. Nutrients that leave the small intestine via blood are delivered first to the liver.
Explanation:
Lymph is a clear fluid that leeks out from the interstitial spaces of the cells and this comprises of electrolytes, blood proteins, and antibodies. It is pushed towards the heart from the lymphatic vessels. The nutrients from the small intestine are drained into the bloodstream and they are circulated to all parts of the body and not directly destined towards the liver.

A group of scientists were using CRISPR to treat a mouse with cystic fibrosis, a disease caused by a defective Cl- channel protein called CFTR. The most common cause of cystic fibrosis in humans is the absence of a phenylalanine, an amino acid, in the CFTR protein, which prevents CFTR from achieving the correct 3-D structure.If the scientists wished to repair this mutation, how would they alter the mutated CFTR gene before using CRISPR to insert the DNA into the mice
Answer:
they can insert the codon that encodes phenylalanine by CRISPR-Cas mediated homology-directed repair
Explanation:
The CRISPR (clustered regularly interspaced short palindromic repeats,)-Cas (CRISPR-associated protein) is a versatile technology for genome editing which has been developed by adapting a natural defense mechanism found in prokaryotic organisms. The CRISPR-Cas genome editing tool can be used to edit DNA sequences in eukaryotic genomes (for example, in human genomes) and thus restore gene function (in this case, the CFTR gene function). The system consists of a Cas protein that cleaves the DNA at specific genomic sites and a single guide RNA (sgRNA) that guides the Cas protein at specific genomic locations. CRISPR-Cas mediated homology-directed repair refers to the process where Cas cuts the DNA to triggers the homologous recombination (HR) DNA repair pathway, by which it is possible to insert new genetic sequences at specific genomic sites (in this case, the codon that encodes phenylalanine within the specific CFTR gene).
