Which molecules are able to pass through the semipermeable membrane? Justify your answer
Answer:
hydrocarbons, oxygen, and water i think educated guess
Explanation:
Semipermeable membranes allow small molecules such as oxygen, water carbon dioxide and glucose to pass through.
What are the features of semi permeable membrane?Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by osmosis.
Membrane separation processes use semipermeable membranes to separate impurities from water. The membranes are selectively permeable to water and certain solutes.
The semi-permeable membrane plays three important roles in EFGF devices: (i) isolating the separation channel from the electrodes, (ii) restricting movement of solutes of interest.

The gases that make up Earth's atmosphere are commonly referred to as air. What are the two most abundant gases in the atmosphere? nitrogen and oxygen water vapor and argon oxygen and carbon dioxide nitrogen and carbon dioxide
hiii answer is nitrogen and oxygen
The two most abundant gases in the atmosphere are nitrogen and oxygen.
What is atmosphere?Atmosphere is defined as the environment that envelops Earth. The gravitational pull of the planet's neighbor, Earth, keeps it close to the surface. The strata of the atmosphere are separated based on temperature. The troposphere, stratosphere, mesosphere, and thermosphere are these layers. The exosphere is a further zone that is located 500 kilometers above the Earth's surface.
It is an amalgam of many gases. Approximately 78% of the air in Earth's atmosphere is nitrogen, while 21% is oxygen. In trace proportions, additional gases like carbon dioxide, neon, and hydrogen are also present in air.
Thus, the two most abundant gases in the atmosphere are nitrogen and oxygen.

What is energy? Give an example of how energy is used in a living organism.
Answer:
Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. Organisms use energy to survive, grow, respond to stimuli, reproduce, and for every type of biological process. The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move.
Explanation:
Energy is defined in the scientific community as the capacity to perform work.
What is Energy?Molecules need energy to be broken down, built up, and transported across plasma membranes.
Energy is required for all life's work. A significant amount of energy is also simply wasted as heat to the environment. The story of life is one of energy flow, including how it is captured, transformed, used for work, and lost as heat.
Because energy can never be regenerated (unlike matter), it is constantly needed by living things.
Therefore, Energy is defined in the scientific community as the capacity to perform work.

If a DNA molecule consists of 29% Guanine, how much cytosine will it contain?
Answer:
Chargaff's rule: C=G => answer is 29%
Explanation:
The percentage of cytosine contained in the DNA molecule = 29%
According the Chargaff's rule the percentage of Cytosine contained in a DNA molecule will be equal to the percentage of Guanine contained in the DNA molecule.
From the question the percentage of Guanine that is contained in the DNA molecule is 29% therefore the percentage of Cytosine that will be contained in the DNA molecule will be = 29%
Hence we can conclude that the percentage of cytosine contained in the DNA molecule is 29%

Did this airplane accelerate or decelerate? Explain your reasoning. c. Should your answer be positive or negative? Explain your reasoning. d. Calculate the acceleration.
Answer:
the airplane slowed down; it came to a stop over 53 seconds, which requires slowing. the airplane decelerated; decelerate is another word for slow down, it also is the opposite of accelerate. The answer should be negative; negative velocity is slowing down. And the acceleration is ~ -11.509 meters every second
Explanation:
the explanations are included in the answer.
Answer:
A) The airplane slowed down. It states that the plane lands and come to a complete stop over a 53 second period.
B) It decelerates. The speed doesn't increase. It slows down.
C) The answer should be positive. Although the deceleration is slowing down the plane, it's not going at a negative speed.
D) The answer is 11.5m/s. I divided the velocity by the amount of seconds it takes to make a complete stop.
