Answer:

D) passive transport

Explanation:

Passive transport is the movements of molecules or ions from the region of its higher concentration to its lower concentration or along the concentration gradient. Since passive transport occurs along the concentration gradient, no energy input is required in the process. An example of passive transport is simple diffusion or facilitated diffusion.

Substances like oxygen pass through the cell without the use of energy and move from an area of high concentration to an area of low concentration that occurs during passive transport.

Further Explanation:

Every molecules that passes across the cell has to cross the cell membrane barrier. The cell membrane is mainly made up of lipid bilayer which allows the hydrophobic molecules to pass throughit and restricts the entrance of hydrophilic molecules. It also allows the uncharged molecules to pass through the cell by simple diffusionand restricts the passage of charged molecules.

<u>There occurs two basic type of transport-</u>

  1. Passive transport
  2. Active transport

Passive transport is the type of transport wherein energy is not required for movement of molecules across the cell. During this type of transport the molecules moves from high concentration gradient to low concentration gradient.

The oxygen is an uncharged molecule that can easily pass through the cell from high concentration to low concentration without the expenditure of energy. In the active transport the molecules moves from low concentration gradient to high concentration gradient which requires energy in the form of ATP.

Osmosis is specifically used for the transport of water molecule from high concentration to low concentration gradient.

ZWhat Organelle that conducts respiration for the cell
baherus [9]

Answer:

The organelle that conduct respiration for the cell is MITOCHONDRIA.

Explanation:

The cells of living organisms are made up of different organelles, each of the organelles have specific functions, which they perform. The mitochondria is the cell organelle that is responsible for carrying out respiration in the cells. Respiration involves the breaking down of glucose molecules in order to produce energy in form of ATP. Mitochondria is also called the power house of the cell because of its function of energy production.

A researcher determines an organism to be eukaryotic, unicellular, and autotrophic. In which taxonomic group should this organis
Aleksandr-060686 [28]

According to the characteristics of this organism, it is classified into the Protist kingdom, which brings together unicellular or simple multicellular organisms that do not form tissues, both autotrophic and heterotrophic.

<h3>What is the kingdom protista?</h3>

It includes eukaryote-type organisms that, due to their characteristics, cannot be included in the rest of the kingdoms of this class.

Although most protists are unicellular, there are also multicellular protists and they can have autotrophic or heterotrophic metabolisms.

Therefore, we can conclude that the protist kingdom groups living beings that have cells belonging to the eukaryote group.

Galina-37 [17]

Answer;

"couples" energetically unfavorable reactions to ATP condensation in order to drive the reaction toward the required product.

Explanation;

-Metabolic pathways are designed to synthesize necessary cellular reagents as required for cellular and tissue function. To accomplish this, the reaction sequence includes both reactions that are essentially irreversible and reactions that are freely reversible (near equilibrium).

-In most cases, cells use a strategy called reaction coupling, in which an energetically favorable reaction (like ATP hydrolysis) is directly linked with an energetically unfavorable (endergonic) reaction.
