Air at 1 atm was closed into a rigid container. It was then heated to a temperature of 911
otez555 [7]

Answer:

Final temperature, T2 = 2460 Kelvin.

Explanation:

Given the following data;

Initial pressure = 1atm

Final pressure = 2.7atm

Initial temperature = 911K

To find the final temperature, we would use Gay Lussac's law;

Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Gay Lussac's law is given by;

PT = K

\frac{P1}{T1} = \frac{P_{2}}{T_{2}}

Making T2 as the subject formula, we have;

T_{2}= \frac{P_{2}}{P_{1}} * T_{1}

Substituting into the equation, we have;

T_{2}= \frac{2.7}{1} * 911

T_{2}= 2.7 * 911

Final temperature, T2 = 2459.7 ≈ 2460 Kelvin.

The artificial cell in the picture below is permeable to monosaccharides but not polysaccharides. Initially, the artificial cell
Ne4ueva [31]

Answer:

Osmosis.

Explanation:

Osmosis is the process which is responsible for the transportation of glucose inside the cell. Osmosis is a process in which micro-molecules such as glucose, ions and gases etc go inside the cell through a semi-permeable membrane. This semi-permeable membrane of the cell only allow monosaccharides but not polysaccharides because monosaccharides is small in size while polysaccharides are larger in size.

Which of the following organisms exhibits cephalization?
bezimeni [28]
Cephalization describes the process by which organisms develop a distinct head. The head of a cephalized organism contains a concentrated group of nerves, or brain, that controls the rest of the organism, as well as specialized organs for consumption and perception, like mouths, eyes and ears. Cephalized organisms exhibit a distinct division between parts of the body; they have a front, back, top and bottom. These animals comprise the bulk of animals that are encountered on a daily basis.
