Answer:
The phenomenon seen by the students is Osmosis.
Explanation:
Osmosis is the movement of molecules from higher concentration to lower concentration through a semi-permeable membrane. This type of movement of molecules occurs in the body cells. When the concentration of molecules is higher outside the cell than the inside, the molecules goes inside the cell through semi-permeable membrane.
Ans.
The blood pressure is defined as the pressure applied by blood cells to the wall of blood capillaries. The normal blood pressure ranges between 120/80 to 140/90, in which upper range shows systolic pressure and lower range shows diastolic pressure.
According to given data, the blood pressure of adult is 200/120, which shows an increase in blood pressure. This condition is known as hypertension. Thus, the nurse should perform next nursing intervention by keeping in mind that the patient is having hypertension and there is a need to control his blood pressure as hypertension can lead to various adverse effects on organs and systems of the body.
Answer: A) Layers 1 and 2.
Explanation:
Secondary succession refers to when species of plants and animals come back to recolonise an area that was destroyed by a natural disaster of some sort or human activity that change the makeup of the area but somehow left it still capable of supporting life.
As the species that come during secondary succession come after the land has been destroyed so to speak, they would be the later species to arrive which would mean that when they died they would be the closest to the surface when their body decays.
Secondary succession would therefore most likely be observed between layers 1 and 2.
Ans.
<em>Viscum album </em>is a plant species, commonly known as mistletoe. It is a hemi-parasitic plant that grows on other trees.
Birds cause seed dispersal as they pick seeds from parent plant and drop them in other places. Seeds of mistletoe are sticky or viscous due to mucus and they provide nutritious food to the birds.
Hence, it can be concluded that the mistletoe seeds show adaptations primarily for seed dispersion, not for infecting the host plant.
Thus, the correct answer to be filled in the blank is 'is nutritious to the dispersing birds.'
