Answer:
The movement of ions or molecules across a cell membrane into a region of higher concentration
Correct answer: B). The phagocytotic barrier, which is a part of innate immunity
The scenario represents the phagocytosis, which is a type of endocytosis by which the cell engulfs microbial pathogens. The main cells of the immune system that are involved in phagocytosis include macrophages, neutrophils, and dendric cells.
It is a mechanism which is used by the immune system to kill and processing of antigen that play an important role in innate immune response.
Hence, the correct answer would be option B.
Answer:D. Prothetic leg
Explanation:
All the other answer choices are still dreamt of by many scientists and engineers. but you always see people wearing prosthetic legs. D is the obvious answer.
The answer is template strand; daughter strand.
<span>In DNA replication, each individual parent strand acts as a <u>template</u> strand for the synthesis of a <u>daughter</u> strand. DNA replication is a process of producing of two identical copies of DNA from the original DNA. DNA molecule consists of two strands and each strand serves as a template strand for the synthesis of a daughter cell. DNA polymerase binds to the origins of replication and synthesises daughter strands by adding complementary nucleotides.</span>
