Which of the following is not a function of the bacterial cell wall?

A. Provide the cell with shape and rigidity
B. Prevent the cell from lysing
C. Protect the cell
D. Provide the cell with locomotion

Answers

Answer:

D

Explanation:

I believe locomotion would be the job of the flagellum

The correct option that is not a function of the bacterial cell wall is : ( D ) Provide the cell with locomotion

The Bacterial cell wall acts mainly as a protective cover to the cell of the bacterium, protecting the cell from lysing ( preventing the breakdown of the cell via osmotic pressure ). The cell wall also provides the cell with shape a and rigidity.

While The locomotion of the cell is not the responsibility of the cell wall but it is made possible by the flagellum.

Hence the non - function of a bacterial cell wall is providing the cell with locomotion.

Determine the rate of oxygen consumption at each temperature for comparison. Then divide the higher rate by the lower rate to obtain the difference (ratio) between the two temperatures. Round your answer to the nearest 0.1. It can be concluded that mouse respiratory rate (increases or decreases) when temperature is lowered. In this experiment there was a fold difference in respiratory rate at the two temperatures.

Answers

Answer:

In mice rate of respiration increases as the temperature drops.

Explanation:

As the temperature decreases, the respiration rate also decrease because the body needs less oxygen for the production of energy. But in the case of mice, the rate of respiration decreases and the reason is the fear. Results showed that the respiration increased in mice as the decrease in temperature occur, caused due to the fear instilled in the mice towards cold temperature so in mice rate of respiration increases as the temperature drops.

Introspection is one of the many sleeping disorders experienced
by people with sleep apnea.
Select one:
True
False​

Answers

Answer:

The statement is false.

Explanation:

Sleep apnea is a respiratory disease characterized by the fact that people who suffer from it habitually snore, have repeated stops of breathing (apneas) and drowsiness during the day. As a consequence, patients who suffer from it cannot rest well during the hours of sleep.The obstruction of breathing causes a decrease in oxygen levels in the body, the persistence of this lack of oxygen could cause pulmonary hypertension and a future right-sided heart failure or myocarditis. Introspection, on the other hand, is the immediate reflective capacity of the human mind to know its own states; it is not associated with sleep apnea.

Explanation:

You perform an experiment in which chromatin is isolated from sea urchin sperm cells and briefly digested with micrococcal nuclease. When the chromatin proteins are removed and the resulting purified DNA is analyzed by gel electrophoresis, you observe a series of DNA fragments that are multiples of 260 base pairs in length (that is, 260 bp, 520 bp, 780 bp, and so forth). a) Although these results differ somewhat from the typical results discussed in the chapter, explain why they still point to the likely existence of nucleosomes in this cell type. b) What can you conclude about the amount of DNA that is associated with each nucleosome

Answers

Answer:

a) DNA fragments associated with histone proteins are all multiple in length (i.e., 260 bp, 520 bp, 780 bp, etc), thereby suggesting the presence of a pattern of organization in the chromatin  

b) it suggests that each unit of organization (ie, each nucleosome) consists of 260 bp associated with chromatin proteins

Explanation:

The nucleosome is considered as the basic unit of chromatin. A nucleosome consists of approximately two turns of DNA wrapped around a core of eight histone proteins (i.e., a histone octamer). The histone octamer consists of two copies of each of the histones H2A, H2B, H3, and H4. Moreover, the nucleosomes are connected together by linker DNA sequences which vary between 10 and 100 bp in length.

A cluster of cases of legionellosis have occurred in your neighborhood. People with the illness have cough, fever, shortness of breath, chest pain and sometimes diarrhea. The illness is caused by the bacterium Legionella pneumophila, a facultative intracellular parasite that survives in certain ameba. The organism has an absolute requirement for L-cysteine. Typically, the organism is grown on buffered charcoal yeast extract (BCYE) agar. In some labs, samples containing suspected L. pneumophila are cultured on traditional BCYE medium as well as BCYE medium lacking L-cysteine. How would L. pneumohila be identified in this situation

Answers

Answer:

The correct answer is - comparing the presence of an essential component of the L. pneumophila that is cysteine.

Explanation:

As we know that L-cysteine is essential for the organism L. pneumophila to grow its colonies. The identification is easy in this situation by comparing the two cultured on the traditional BCYE medium and BCYE medicum without L-cysteine.

Colonies that grow on traditional BYCE medium are likely L. pneumophila as they required L-cysteine but not on BYCE medium lacking cysteine.

19. Fresh poultry should be rejected when:

A. It has been shipped in plastic wrap
B. It is slightly sticky to the touch
C. There is no discoloration
D. The receiving temperature is 38°F

Answers

Answer:

B

Explanation:

Fresh poultry should be rejected when the receiving temperature is 38°F. Therefore, option (D) is correct.

Poultry must be stored and transported at or below 40°F to guarantee food safety and inhibit the proliferation of harmful bacteria. Exposure to unsafe temperatures during storage or transportation can increase the risk of bacterial contamination and foodborne illness if the receiving temperature exceeds the threshold.

Indicators like plastic wrap during shipment, slight stickiness, or lack of discoloration do not necessarily imply safety concerns or spoilage with fresh poultry, as mentioned in the other options.
