The correct answer is that it produces antibodies against the sensitizing antigen.
Plasma cells are formed in the bone marrow, the B cells divide into plasma cells, which generate molecules of antibody. Once discharged into the lymph and blood, these antibody molecules combine with the target antigen, that is, foreign substance and starts its destruction or neutralization.
Answer:
Producers ( also called autotrophs) are the organisms that synthesize their own ( glucose) food using carbon dioxide and water in the presence of sunlight ( photosynthesis). They use energy from sunlight to convert it into chemical energy ( that is stored in the glucose). Autotrophs occupy the base of a food chain within the ecosystem as they are first trophic level for the energy transfer.
Decomposers ( such as bacteria and fungi that act on dead plants and animals) can recycle the organic matter back into the food web and biogeochemical cycles in the form of nutrients such as carbon and nitrogen.
Thus, the correct answers are-
1) Producers
2) Decomposer
3) Sunlight
4) Base
Answer:
True
Explanation:
The Devonian Period comprises the years between 416 million and 354 million and is subdivided by periods: Lower (the oldest), Middle and Upper (the most recent).
During this period, the main transformations occurred in the flora, with the exponential growth of small terrestrial plants through the development of spores. With this process, plants will become more similar with modern plants. During this period the plants were able to fertilize themselves with the seeds and reach the height of trees. They formed the first forests to be recorded, with the appearance of licopodia, ferns and progimosperms.
