Which best describes the relationship of the embryo and the fetus.

1 answer:

8 0

The words are synonyms, if you look it up in a dictionary you can find that a fetus is "an unborn or unhatched offspring of a mammal, in particular an unborn human more than eight weeks after conception". However, in organisms that reproduce sexually, an embryo develops from a zygote, the single cell resulting from the fertilization of the female egg cell by the male sperm cell. The aforementioned zygote possesses half the DNA of each of its two parents. Moreover, for plants, animals, and some protists, the zygote will begin to divide by mitosis to produce a multicellular organism, which in turn will create and embryo.

The process of phagocytosis involve all of the following except

evablogger [386]

Hello, I figured your question was missing its options so I went online to find them. Here they are:

The process of phagocytosis involves all of the following EXCEPT :

a. adhesion.

b. secretion of cytotoxins.

c. elimination.

d. vesicle fusion.

e. chemotaxis.

Answer:

The correct answer is: b) secretion of cytotoxins.

Explanation:

Phagocytosis is a mechanism performed by cells in which the plasma membrane engulfs a large particle. Phagocytosis is used by cells in the immune system to ingest pathogens like viruses and bacteria.

Phagocytosis consists of many steps:

activation - the phagocytes that were resting are activated in the inflammatory response when a pathogen enters the body.
chemotaxis - this refers to the process in which the phagocyte moves to the pathogen by following the chemical factors released by these germs.
adhesion - the phagocyte attaches to the pathogen.
ingestion /vesicle fusion - the phagocyte sends pseudopods to engulf the pathogen, and places it in a phagosome, which is an endocytic vesicle. The phagosome and the phagocyte will fuse so the pathogen gets inside.
elimination - the pathogen is destroyed in the phagocyte by the lysosomes present in it.

The secretion of cytotoxins is not a part of the phagocytosis, and is a process exclusive to T cells (leukocytes that lack the ability to phagocyte).
