I just took the Test
Answer: When you mix sand and water there are no reactions. The sand sits at the bottom of the water because the sand is heavier than the water is.
Answer:
Root hairs appear in the root maturation zone and differentiate from unspecialised cells called trichoblasts.
Explanation:
Root hair arises as a small protrusion surrounded by a cell wall, they are found in the piliferous area; they can originate in unspecialised epidermal cells, in some called trichoblasts. The bump begins to elongate and moves away from the epidermis, forming root hair. The root hairs as they lengthen, it is seen that their content shows a polarized distribution, the apical part is constituted mainly by vesicles secreted by the Golgi apparatus that contain the precursors of the cell wall that are to be released by exocytosis. Trichoblasts can be arranged in different ways, there are roots where any of the cells that are part of the rhizodermis can give rise to a root hair. In other roots, trichoblasts and atricoblasts have been seen to be distinguished alternately along a row of cells.
Answer: 3
Explanation:
Given :
numC = 12
while numC > 3:
numC = numC / 2
Initial value of numC = 12
The condition checks if the value of numC is greater than 12, only then will the statement be executed and the loop isn't altered
numC = 12 is greater Than 3 ;
numC = numC/2 = 12/2 = 6
numC is now 6 ;
numC = 6 is greater than 3
numC = numC / 2 = 6/2
numC is now 3
numC = 3 is not greater than 3 ; hence, loop terminates (condition isn't met)
Hence , numC = 3
Answer: Cellular transport independent of ATP like osmosis and difussion (Simple and facilitated).
Explanation: The animal affected has a mitochondrial disease that affects its capacity of ATP production, thus, the animal active transport will be afected since require ATP. On the contrary, the animal passive transport will be functional because its independent of ATP, like osmosis which is water transport in favor of concentration gradient and facilitated diffussion of small molecules.
