Answer:
Inflammation
Explanation:
Inflammation is an immune response produced in the body in response to the damage or trauma caused by physical or chemical factors.
The injured tissue can allow the entry of the microorganism in the body which could cause disease therefore the immune response gets activated to eliminate the pathogen.
The inflammation is marked by the swelling and redness in the injured portion due to the increased flow of blood carrying the White blood cells in that area. The immune cells interact with the pathogen and kill the pathogen.
Thus, Inflammation is the correct answer.
Answer:
This is a scientific model
Explanation:
This is a scientific model because it rightly explains the water cycle and makes it easy to understand in a list of steps and examples
hope it helps!
Answer:
Temperatures gradient
Explanation:
There are distinct temperature gradient differences in the layers of atmosphere usually due to the main air molecule composition of the layers, the density of the molecules. The Troposphere the lowest layers is the densest and temperature decreases with increase in altitude. The stratosphere, on the other hand, has an increase in temperature with increase in altitude. Temperatures decrease with altitude in the mesosphere while the parameter increases with altitude in the thermosphere.
Answer:
The correct answer is option B, that is, less genetic diversity in later generations.
Explanation:
A pandemic that spread across Europe between 1348 and 1350 was named as the Black Death. It has been predicted that of the total population of Europe at that time 30 to 60 percent died due to the pandemic. The geneticists are still trying to document the influence of Black Death on the population of Europe today.
It has been found that in England, the genetic diversity is found much lower in comparison to what it was in the eleventh century, and is primarily due to so many people dying in the 1300s. However, the rest of Europe does not demonstrate a dropped amount of genetic variation, which maybe because of the enhanced patterns of migration in other places.
Answer:
Endospores Staining
Endospores are substances that are formed inside of specific bacterial cells which boost their survival rate in times of harsh conditions.
Gram staining alone is not sufficient to observe the endospores, which seems apparently clear when Gram-stained cells are observed.
Endospore staining employs two stains to identify endospores from other cell components.
•The Schaeffer-Fulton method employs heat to promote the primary stain (malachite green) into the endospore. Rinsing with water will well wash away the colour from the cell, as the endospore still appears to be green stained. Counterstaining pink with safranin will show the shape and location of endospores, if they are a part of the cell. The green endospores will be seen inside the pink vegetative cells or it will appear distinct from the pink cells in total. If no endospores are seen, only the pink vegetative cells will be observable.
The attached image shows a stained preparation of Bacillus subtilis revealing the endospores as green and its vegetative cells in pink coloration.
Endospore-staining procedures are essential for observing Bacillus and Clostridium, two genera of endospore-forming bacteria, production of bioterrorism agent from B. anthracis (which causes anthrax.
