Streptococcus infection carries all the symptoms mentioned.

<h3><u>Explanation</u>:</h3>

<em>Streptococcus pneumoniae</em> and <em>Diplococcus pneumoniae</em> are the organisms that gram positive bacteria. These bacteria enters the respiratory system from droplet method propagation which is through aerosol or water droplet inhalation which are infected with these bacteria. These bacteria leads to the severe antigen antibody reaction inside lungs which leads to high rate of mucous secretion. This leads to formation of pneumonia.

These bacteria are mainly seen in tropical countries with warm climate and humid environment. These bacteria doesn't spread through contagious methods like touching. But the protection must be taken as these patients cough can contain lakhs of these bacteria which are enough to infect a healthy individual.

Legionella infection

Explanation:

Legionella genus of bacteria are pathogenic gram-negative bacteria. The species Legionella pneumphila causes legionella infection which leads to legionellosis.

Legionellosis includes both the flu-like Pontiac disease as well as the acute highly severe pneumonia called the Legionnaires.  

Legionellosis occurs when water droplets or aerosolized water contaminated with Legionella species is inhaled. These bacteria mostly are present in aquatic environment and can thrive and survive in water with warm temperatures.

Legionella infections are non-contagious and does not spread from person to person but only spreads through inhalation of contaminated water droplets.

Legionnaires causes lung inflammation and severe pneumonia and if untreated can also be fatal

What part of the intestinal tract prevents backflow of food from the stomach into the esophagus? a. diaphragm b. lower esophagea
lara31 [8.8K]

Answer:

The correct option is b. lower esophageal sphincter

Explanation:

The esophagus is the initial part of the digestive tract and its function is the transport of the alimentary bolus from the pharynx to the stomach, through the thorax and avoid the reflux thereof. It begins and ends in two sphincter structures, the upper esophageal sphincter and the lower esophageal sphincter, which separate it from the pharynx and stomach. The lower esophageal sphincter has two functions: relax during swallowing and prevent reflux of the gastric contents into the esophagus in the postdeglutory period. After swallowing, there is a relaxation of the lower esophageal sphincter, pressure dropping to levels similar to those of the gastric fundus, which allows the bolus to enter the stomach. This relaxation lasts a few seconds and is followed by a strong contraction that prevents backflow of food.

Step 11 of skeletal muscle contraction:__________.
malfutka [58]

Answer:

The suitable option will be - B

B) Phosphate and ADP form to make ATP which binds to the myosin head and causes cross-bridge to detach.

Explanation:

Until step 11, skeletal muscle has already done cross-bridge and power stroke. ADP is released just after the power stroke. After that phosphate and ADP form a new ATP which gets bound to the myosin head.  

Then at step 11, cross-bridge is released as a new ATP is bound to myosin head.  

So, we can say that option B is correct.
