Explanation:
Phagocytosis, describes the mechanism by which cells engulf large particles into compartments in the cell called phagosomes.
The steps of phagocytosis in order:
- Chemotaxis of phagocyte to microbe occurs.
- Phagocyte adheres or attaches to microbe.
- Pseudopods of the phagocyte engulf and internalize the microbe, forming a phagosome.
- Lysosome fuses with the phagosome, forming phagolysosome.
- Digestion of microbe occurs within phagolysosome.
- Indegistible material is discharged.
Further Explanation:
While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, active and passive transport. However some very large molecules require specialized type of active transport in order to move across the membrane this includes endocytosis and exocytosis.
During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of invagination; piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule, this breaks off from the membrane to form an intracellular vesicle. Different methods of endocytosis such as Phagocytosis, Pinocytosis and receptor-mediated endocytosis, take in cells, water and targeted substances respectively. During phagocytosis, cells engulf large particles into compartments in the cell called phagosomes, after which they are broken down by specialnlysosomes containing enzymes.
In exocytosis, large particles (proteins, neurotransmitters, waste material etc.) are surrounded by a phospholipid membrane in a vesicle. However, this membrane is formed in the cytoplasm, and attaches to the plasma membrane’s interior in a process opposite to endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.

There are multiple factors that don't play a part in water movement. We need a list of possible options.
The answer is mitochondrion, it is called as "the power of cell"
Answer:
Explanation:
A Pure bacterial culture must be grown in sterile tryptophan or peptone broth for 24–48 hours before performing the test. A sterile environment helps to avoid contamination.
When a test is conducted and it shows the presence of a red or red-violet color in the surface alcohol layer it means the result is positive
But when the colour is yellow it indicate negative reaction due to glucose fermentation.
A deviation from two color may also occur when we have an orange color. This colour change is due to the presence of methyl indole
When there is no color change this indicate No decarboxylase which is an enzyme needed for the fermentation reaction.
Color changes are indicator of how successful the reaction was.
The variation in beak type enables the different individuals in a population to feed on different food sources.
The shape of the beak is key to determining the primary food source of the bird. Certain birds species have specialized beaks, but within populations of those species, there is a variation in beak shape.
This gives the population the ability to respond to changes in the environment and availability of different food sources.
For example, if because of a dry period there is a shortage of fruit, some individuals in the population have the beaks that enable them to feed on other things, survive and leave offspring.
