Response: a) true
Clarification: The liquid within the egg plays a critical role in ensuring the embryo's survival and providing a fluid medium necessary for its development.
Population density = total number of individuals divided by land area
land area should be expressed in square kilometers
thus, 120 ha = 120 x 0.01 = 1.2 square kilometers since 1 ha = 0.01 square kilometers
total population= (80 x 1500)/100 = 1200
so, the population density is 1200/1.2 = 1000
Answer: Amino acids enter the body using a Sodium cotransporter, employing a mechanism similar to that of monosaccharides.
Explanation: Amino acids are taken up via a Sodium cotransporter, akin to the absorption of monosaccharides. Once absorbed, they cross the alabaster membrane through facilitated diffusion. Di- and tripeptides utilize distinct H+ dependent cotransporters, and upon entering the cell, they are hydrolyzed into amino acids.
