Answer:
Pulmonary plague, septic plague and bubonic plague.
Explanation:
So, Yersinia pestis is a rod-shaped bacterium. This microorganism can affect humans through the flea Xenopsylla cheopis. Then, the disease can manifest in three ways: pulmonary plague, septic plague or bubonic plague.
Pneumonic plague is the form of the disease that infects the lungs and its symptoms begin abruptly two to three days after exposure to bacteria. Patients have a high fever, chills, fast heart rate and often severe headaches.
Another form of the disease is the septicemic plague and the infection spreads in the bloodstream. The most common symptoms are nausea, vomiting, diarrhea, and abdominal pain.
Finally, bubonic plague, or also known as the minor plague, is a milder form of the disease that affects the lymphatic system and its symptoms are swollen lymph nodes, fever, headache, and exhaustion.
Answer:
<h3>
<em><u>Archaea</u></em></h3>
Explanation:
Archaea contains DNA not held in a nucleoid or nucleus. They tend to live in harsh temperatures/climates and are found in thermal vents, and they can survive on certain non-organic substances.
Now bacteria contains a nucleoid which holds the DNA, and Eukarya (plant and animal cells) also have DNA but have membrane-bound organelles that are like nucleus.
Answer:
Antibiotic resistance occurs when bacteria do some variation in their genome that allows bacteria to eliminate the effect of antibacterial drugs. Irregular or excessive antibiotics use is the main cause of generating antibiotic resistance bacteria.
So antibiotics should be taken only on the prescription of doctors and a complete course of antibiotics should be done to eliminate all the bacteria so that no bacteria is left to generate antibiotic-resistant bacteria.
Antibiotics should be avoided in viral infection as antibiotic does not kill viruses as it is only beneficial in bacterial infection.
<span>Antlion pits are often spatially aggregated even though there are potential negative effects associated with the aggregation (e.g., heightened competition and predation risk). This study investigated the possibility that a strategy leading to aggregation can be an evolutionarily stable strategy (ESS). In particular, the strategy considered was ‘decreasing relocation tendency when there are neighbors’. An individual based model showed that the strategy can be the unique ESS when the spatial distribution of prey is not completely random and antlions can learn it from their past foraging experiences. A laboratory experiment was conducted to examine the effects of the presence of neighbors and foraging success on the relocation behavior of antlion larvae. Antlions reduced their relocation tendency with respect to these factors, consistent with the predicted ESS. The results suggest that pit aggregations are formed because antlions reduce their relocation tendency when neighbors exist, and this strategy is an ESS.</span>
