Which of the following statements best describes what happens when a bacterial cell is placed in a solution containing 5 percent
lora16 [44]

Answer:

C) Water will move out of the cell.

Explanation:

In microbial growth experiments, when a bacterium is placed in a Petri dish with a solution that contains dissolved salt (NaCl) - a hypertonic solution -, the result will lead to the <u>dehydration and shrinking of the bacterial cell</u>.

This condition will eventually cause the rupture of the cell, resulting in the diffuse of H20 molecules from the plasma membrane, that is, the water moving out of the cell.

Here are the cases for you to solve remember that you just have to choose ONE of the following cases to discuss in your Case Stu
Zielflug [23.3K]

Answer:

It is known that the lungs and mouth are associated with a passage known as trachea. At the time of an infection, if there is a passage between the lungs and the mouth, the body makes a fluid known as sputum, also known as phlegm. By coughing the body is in real sense attempting to get rid of this phlegm.  

The most general pathogens, which are found in Sputum culture are Haemophilus influenzae, Streptococcus pneumonia, Mycobacterium species, and Staphylococcus aureus. In the given case by observing the symptoms demonstrated by Navin, one can presume that Navin is suffering from Tuberculosis.  

The disease is the result of Mycobacterium tuberculosis bacteria. These are the pathogenic bacteria, that comprise a mycolic acid on its cell surface. Due to the presence of this coating, it is tough to determine it with the help of Gram staining. Thus, Acid-fast staining, like Zehl-Neelsen is used.  

These bacteria are aerobic in nature and need a huge concentration of oxygen, it mainly infects the respiratory system of the mammals, and generally spreads from infected persons via sneeze, coughing, talks, or laughing. Smoking is also a supplementary element of the condition. The major symptoms of the condition are weight loss, fatigue, severe cough, no appetite, chest pain, and night sweats.

A pea plant with round seeds (RR) is crossbred with another pea plant with wrinkled seeds (rr). What is the probability of the o
vichka [17]

Answer:

0%

Explanation:

The cross of a pea plant with round seeds (RR) with another pea plant with wrinkled seeds (rr) is shown as under :

P              RR  x   rr

F1          Rr    Rr    Rr   Rr

It is clear from the cross above, all the 4 probable progenies in filial 1 (F1) generation will be heterozygous with Rr genotype. Not even a single progeny will have homozygous recessive genotype which is responsible for producing wrinkled seeds. Also, even though the genotype of the progenies will be Rr not RR yet phenotypically they all will have round seeds i.e. they will show dominant trait. The reason behind it is that one of the alleles R which is responsible for dominant trait will mask the expression of recessive allele r. So, wrinkled phenotype which is a recessive trait will not be observed in any of the progenies.
