Answer:
Cloud iridescence
Sunlight travels through the cloud and is diffracted by the droplets, creating the rainbow effect. It can appear as a patch or band at the cloud's edges and changes as the cloud evolves.
Explanation:
<span>The correct answer is horizontal gene transfer, transduction.</span>
Transduction (a type of horizontal gene transfer)is the process by which foreign DNA is introduced into a bacteria cell. When viruses infect bacterial cells, their DNA is integrated into a bacterial chromosome and thus harness the replicational, transcriptional, and translation machinery of the bacteria. As a result, bacteria cell makes numerous virions (viral particles).
Answer:
Adaptive immune defense system consists of lymphocytes like B-lymphocytes and T- lymphocytes. B-lymphocytes provides humoral immunity while T- lymphocytes provide cell-mediated immunity to the body.
99% of lymphocytes circulate freely in the blood and lymph. B lymphocytes differentiate into plasma B cells and B memory cells when interact with antigen presented by T helper cells.
Then plasma cells secrete antibodies in the circulation which binds to extracellular antigens through antigen-binding site. Then the bounded antigen is recognized by receptors present on phagocytic cells. This receptor binds the Fc region of antigen bounded antibody and destroy the antigen by phagocytosis.
Answer:
spindle fibers act as guides for the alignment of the chromosomes as they separate later during the process of cell division.
Explanation:
They play a role in mitosis of animal cells and plant cells are able to reproduce without them.
Research however has shown that mitosis can take place in animal cells after centrioles have been destroyed. ... In higher plants mitosis takes place perfectly satisfactorily with microtubules forming spindle fibres but without the help of centrioles.
Hope this helpse!! Brainliest?? Anyways have a great day my loves<3
