Explanation:
During endocytosis large cells, particles, and cell fragments moved across the plasma membrane through a process of invagination; part of the external cell membrane folds into itself and creates a small pocket that surrounds the target molecule, this breaks off from the membrane to form an intracellular vesicle.
Specific endocytosis processes, such as phagocytosis, pinocytosis, and endocytosis are regulated by receptors-they take in cells, fluids, and specific compounds respectively. During phagocytosis, cells absorb large particles in cell compartments called phagosomes, after which specifically enzyme-containing lysosomes break them down.

Answer;
D) D
(Gap junctions)
Explanation;
Gap junctions are tunnel like junctions that can occur anywhere along the lateral membranes of adjacent cells. They allow ions and small molecules to pass to one cell to the next for inter-cellular communication.
They function by allowing the exchange of ions, second messengers, and small metabolites between adjacent cells and are formed by two unrelated protein families, the pannexins and connexins.The protein channels that make up gap junctions consist of two connexons. One connexon resides in the membrane of one cell.
Explanation:
Determining a substance's physical or chemical identity. What are the two main requirements for identification? The adoption of testing procedures that give characteristic results for specific standard materials and the number and type of tests needed to identify a substance to exclude all other substances.
Heterotrophs are organisms that must consume food from other organisms because they are unable to synthesize their own food molecules.
<h3>What is heterotrophs?</h3>
- An organism is referred to be a heterotroph if it is unable to manufacture food on its own and must obtain it from other sources of organic carbon, primarily plant or animal materials.
- Heterotrophs are primary, secondary, and tertiary consumers in the food chain but not producers.
- Because they eat producers or other consumers, heterotrophs are referred to as consumers.
- Humans, dogs, and birds are all instances of heterotrophs.
- In a food chain, a group of creatures that supply energy and nutrients to other organisms, heterotrophs occupy the second and third levels.
- An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy.
- Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition."
- Autotrophs and heterotrophs are two main classifications of organisms depending on how they receive energy and nutrients.

Answer:
C). The particles move slower until the matter changes into a liquid.
Explanation:
When heat is removed the particles condense turning it into a liquid and further cooling will turn the gas into a solid.
