The _____ passively diffuses oxygen and carbon dioxide in and out of the cell.Through the plasma membrane, oxygen and carbon dioxide diffuses passively.
However, it is thru a transport that they in act to diffuse, -concentration gradient.
The right answer is thinking.
The "thinking" is not a reflex, it is a competence that the newborn will acquire a few months after his birth.Studies have shown that babies begin to think 4 months already, they have an idea about the laws of physics. He continues to reconstruct the image he makes of the world according to the latest information he receives.
At 8 months, his brain already models the probability of future action by confronting his memory with the information his senses provide. One of the keys to human intelligence.
Answer:
The solution is 0, 90 molal. See the explanation below, please
Explanation:
Molality is defined as moles of solute in 1 kg of solvent (1000 grams). The following three simple rule must be performed:
We calculate the weight of 1 mol of CaCl2
Weight Ca =40, 078 g
Weight Cl= 35, 453 g
Weight of 1 mol of CaCl2=40, 078g + 2x (35, 453g )= 110, 98g
110, 98 g ---1 mol
25 g---X= (25g x1 mol)/110, 98g= 0,23mol
250g solvent -----0,23 mol CaCl2 (the solute)
1000g solvent ----X = (1000g x0,23mol)/250g =0,90 mol solute
The solution is 0,90 molal
