<span>When you are on
standby and it happens that a nearby infant suddenly begins to cough, you need
to give your attention to the infant just to check the infants’ condition. If
you have the medical knowledge, you can assess the infant by checking if there
is an obstruction to his/her mouth and if it is conscious. Then, you can give
sets of 5 back slaps and 5 chest thrusts to remove the object.</span>
Frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.
<h3>Is frozen water more or less dense than liquid water?</h3>
Ice is less dense than liquid water because when the water becomes solid due to low temperature, the density of ice become decreases. Due to less density, the ice floats on the water surface.
Water is attracted due to its polar nature so adhesive forces pull the water toward other molecules. Water is transported in plants through both cohesive and adhesive forces. These forces pull water and the dissolved minerals from the roots to the upper parts of the plant.
So we can conclude that frozen water is less denser than liquid water so that's why ice floats on the water in cold areas.

Answer:
The correct answer is - carriers of Sickel cell have advantages.
Explanation:
Sickle cell is a condition or disease that involves several other groups of disorders that affect the molecule that carries oxygen in RBC to cells all over the body. It leads to the atypical hemoglobin called hemoglobin S that distorts the RBC in the crescent or sickle shape.
The people with sickle cell trait that is that an individual is a carrier for the disease have one normal hemoglobin gene and other is hemoglobin S gen has an advantage and increase the chances of survival. It is determined that it has some kind of protective advantage against malaria.
Thus, the correct answer is - carriers of the sickle cell have an advantage.
The answer would be B.
The new species will start competing for all of the necessities that everything else needs to survive resulting in everything else reducing in population size.
Hope this could help,
