Answer:
Polar; hydrophobic (Ans. B)
Explanation:
Glycerophospholipids are known as the class of lipids which are found extensively in the biological membrane. They are usually consisting two regions of lipids which provide structure to the lipid bilayer in which the hydrophilic heads (polar) attaching outside to the cell and the hydrophobic tails (non-polar) pointing insides to the cell membrane.
Glycerophospholipids helps to provide permeability and fluidity to the membrane and also helps in the programmed cell death, and modulation of actions of membrane-bound enzymes.
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.
The excretory system is most likely to respond when an animal is thirsty in this way: B. by retaining body fluids.
Because the body doesn't get enough fluids to not be thirsty anymore, it retains whatever fluids it already has in it until the thirst is satiated.
