From this we can conclude that the human digestive system does not produce enzymes that can break down cellulose. The correct option among all the options that are given in the question is the fourth option or the last option. I hope that this is the answer that has come to your desired help.
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.
Answer:
The False statement is
Exchange gases with blood
Explanation:
Gas exchange occurs at the alveolar level which is part of the lower respiratory track
By looking for the presence of the germ layers and the primitive gut in the embryo
