C. Macrophages
When Macrophages approach a foreign pathogen they ingest the pathogens through phagocytosis, the Macrophages show the foreign antigen proteins on their cell surfaces.
The Helper T Cell recognizes the antigen on the surface of the macrophage and starts an immune response to the invading pathogen by sending out a chemical message
After that the B-cells produce antibodies that are specific to the antigens of the pathogens that slow them down so the macrophages can engulf them.
Answer:
These organisms are called the producers, and they get their energy directly from sunlight and inorganic nutrients. The organisms that eat the producers are the primary consumers. They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians).
Los peroxisomas juegan un papel clave en la oxidación de biomoléculas específicas. También contribuyen a la biosíntesis de lípidos de membrana conocidos como plasmalógenos. En las células vegetales, los peroxisomas llevan a cabo funciones adicionales, incluido el reciclaje de carbono del fosfoglicolato durante la fotorrespiración.
Answer:
If the cells are submerged in pure distilled water, each cell will absorb water from the environment where it is located, increase its volume and possibly break.
Explanation:
The cells maintain an osmotic balance relationship between their cytoplasm and the extracellular space, that is, the cell is isotonic with the medium.
When a cell is exposed to a hypotonic medium -such as that which provides pure distilled water- water will pass through osmosis from the extracellular space to the cytoplasm, causing the cell to increase in volume (swell) and the increase in internal pressure can Make it break.
<u>In osmosis, water passes from space with less concentration of solutes to the highest concentration</u>.
