Stem cell and cancer question. Please answer Asap!!
malfutka [58]

Metastasis will happen and cancer cells invade nearby healthy cells, tissues, lymph nodes, organs or will migrate to distant organs.

The two different types of stem cells broadly classified as  are Embryonic stem cells and adult stem cells. Embryonic stem cells are obtained from the blastocyst layer of the embryo and are pleuripotent. Whereas adult stem cells are the undifferentiated cells from tissues of an adult or a child. They can be unipotent or multipotent.

Explanation:

Cancer cells migrate to other parts of the body via blood and lymphatic system. This is called as metastasis. Cancer cells when becomes tumour they develop their own blood vessels and obtain nutrients from them. Once the tumour gets big it pushes the normal healthy cells of the neighbouring tissues and keeps on spreading.

Stem cells obtained from the embryo can differentiate into any types of cell and when grown in-vitro can dramatically form the three germ layers.

The adult embryo cells are found in less quantity, their role is to repair the tissue they reside in.

mestny [16]

Answer and Explanation:

  • Eosin Methylene blue agar or EMB agar consists of sucrose, lactose, methylene blue and Eosin Y. These segments make it a differential medium which permits development of gram-negative microorganisms. Gram positive microscopic organisms develop inadequately on this medium.  
  • It is particular for development of gram-negative microscopic organisms. It likewise separates between non-fermenting gram negative enteric microscopic organisms and lactose fermenting.  
  • Lactose fermenting gram negative microscopic organisms use lactose to deliver corrosive which changes the shading to dull purple. Some of the lactose fermenter will exhibit dim provinces with green metallic sheen while different settlements with purple focus. Green metallic sheen is because of creation of solid acids.  
  • In the event that the beginning pH is 7.8 rather than 6.9-7.3, the color won't change shading regardless of creation of acids. Consequently, it won't be conceivable to separate between lactose fermenter and non-fermenters.
