Which form of cell transport allows small molecules to move from an area of higher concentration to an area of lower concentration without energy being required from the cell?a. osmosis
b. pinocytosis
c. phagocytosis
d. simple diffusion

Answers

Osmosis is the movement of small molecules from an area of higherconcentration to an area of lower concentration without energy being requiredfrom the cell. It only uses the difference in concentration of the surroundingmolecule. The answer is letter A. It is not a simple diffusion because thestatement above is in the form of cellular transport. It is not phagocytosis becausephagocytosis is the process by which a protest or phagocyte engulfs a solidparticle to form phagosome. It is not pinocytosis beacasue it is a form of celldrinking wherein small particles are brought into the cell and then suspendedwithin the vesicle.

Name the internal cross walls that separated the inside of an earthworm.

Answers

Interior to the muscle layer is a fluid-filled chamber called a coelom that by its pressurization provides structure to the worm's boneless body. The segments are separated from each other by septa (the plural of "septum") which are perforated transverse walls, allowing the coelomic fluid to pass between segments.

Final answer:

The internal cross walls in an earthworm are known as septa, which divide the earthworm's body into segments, aid in locomotion, and play a role in respiration and excretion.

Explanation:

The internal cross walls that separate the inside of an earthworm are called septa(singular: septum). These septa compartmentalize the earthworm's body into a number of segments. The septa provide structural integrity to the earthworm's body, help in locomotion by allowing different body segments to move independently, and also play a crucial part in the earthworm's respiration and excretion processes.

During cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes. In order for this to occur, which of the following statements must be true?A.) The energy in the new compounds that are formed must be equal to the energy in the bonds of the food molecules.

B.) New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.

C.) New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken.

D.) The new compounds that are formed must be more complex than the food molecules that were broken down.

Answers

During cellular respiration, the bonds of food molecules are broken to energy can be released to fuel other cellular processes. In order for this to occur, new compounds with lower-energy bonds must be formed when high-energy bonds in food molecules are broken.
This is due to the Law of Conservation of Energy. 

Answer:

The correct answer is statement B.

Explanation:

The cellular procedures of respiration and photosynthesis involve the transformation of energy and matter. On the basis of the law of conservation of energy, energy can neither be formed nor destroyed. Thus, to attain excess energy in order to provide energy for the cellular procedures, the bonds produced in the new compounds must possess less energy in comparison to the bonds in the original food molecules.
