State one way the white blood cells protect the body from foreign microbes

Answers

Answer:

Two types of white blood cells are lymphocytes and phagocytes which protect the body from foreign microbes.

Explanation:

The acquired immunity requires white blood cell which are phagocytes and lymphocytes that act on the microbes or antigen.

Phagocytes surround any microbes present in the blood and inundate them. these white cells are attracted to pathogens and attach to them.

Lymphocytes recognize proteins present on the surface of microbes or pathogens called antigens. They detect that these are not naturally found within your body and produce antibodies.

Thus, through the phagocytes and lymphocytes are the white blood cells protect the body from foreign microbes.

Phagocytosis of the microbes that enter the body or tissues. Also lymphocytes build specific antibodies against microbes.

Place the events of fertilization and implantation in order. 1. Implantation of the developing embryo. 2. The developing embryo becomes a blastocyst which consists of a hollow ball of cells. 3. Mitosis occurs in the Fallopian tube. 4. The cortical reaction occurs, preventing polyspermy. 5. The egg is fertilized by the sperm.

Answers

Answer:

The correct order is

5, 4 , 3, 2, 1

Explanation:

The first stage is the fusion of sperm with egg in fallopian tube which induces chemical reactions that prevents fusion of multiple sperm with one egg. This is known as preventing polyspermy.

After this the fused egg starts dividing and growing through the process of mitosis. The growing zygote reaches the stage of morula after few cell division and continues the division process till it reaches the stage of blastocyst.

The blastocyst now move down the fallopian tube to attach to the wall of uterus. This stage is known as implantation.

Hence, the correct order is 5, 4 , 3, 2, 1
