In How to Kill a Mockingbird, Atticus warns them not to kill a mockingbird, because it doesn't harm anybody. Boo Radley could be considered the mockingbird, because although he is away by himself and harming nobody, the children mock and disturb him.
D.) COLORFUL FLOWERS is the structural adaptation that some plants have to attract pollinators.
The more colorful the flowers are, the more insects are attracted to the flowers. Insects would then land on the flowers wherein the pollen in the flower will stick to the body of the insect. Insects are called pollinators. They help in the pollination of the flowers.
Pollination is the transfer of pollen from the flower's anthers to its stigma or another flower's stigma which will start up its fertilization.
Answer:
The correct answer is: deposition of interferon on bacterial cells.
Explanation:
Phagocytosis is the mechanism by which a cell uses its plasma membrane to ingest a big particle, forming a phagosome within the cell. It's a form of endocytosis used by the <u>immune system to eliminate pathogens such as </u><u>bacteria </u><u>and cell debris</u>.
Phagocytosis can be enhanced through various ways when an infection is taking place in the body. For example, cytokines and TNF are secreted by different kinds of cells to stimulate this process - for these cytokines to be released, certain parts of the bacteria called PAMPs need to be recognized by specific receptors located in phagocytes and epithelial cells called TLRs. Another way to stimulate this mechanism is by depositing complement fragments on bacterial cells, which is done thanks to the Complement cascade, a system of great importance in the innate immune response against extracellular bacteria - these fragments will opsonize ("mark") the pathogens for the phagocytes to recognize them and engulf them.
Interferon, on the other hand, while hugely important on the immune response against viruses and other pathogens that infect our cells by entering them and using their organelles to replicate and translate proteins, is not an enhancer of phagocytosis, as it is mostly involved in the translation of genes that will lead to the infected cell's death.
Because they rely on their dense fur for insulation from the chilly ocean water, sea otters are particularly vulnerable to the detrimental effects of an oil spill. If a sea otter swims into an oil spill, its fur becomes soiled and loses its insulating qualities, allowing water to penetrate to its skin, causing hypothermia and ultimately, death.
hope this helps?
