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 probability is 1/16 that a gamete will receive only paternal chromosomes. In life
cycles that alternate between haploid and diploid stages, fertilization doubles
the number of chromosomes per cell, The pairing of chromosomes along
their lengths , which is essential for crossing over is referred to as synapsis
The cold-blooded animals need to bask in sunshine before they can move as quickly as warm-blooded animals on a cold day because it increases their rate of metabolism.
<h3>What are cold-blooded animals?</h3>
Cold-blooded animals are those animals that are not able to regulate and maintain their internal body temperature when there is change in the external environment.
Example of cold-blooded animals are snakes and turtles. They expose themselves to sunlight to help them with their body metabolism.
Therefore, the cold-blooded animals need to bask in sunshine before they can move as quickly as warm-blooded animals on a cold day because it increases their rate of metabolism.

The process of dissolving two organic molecules in a polymer and recombining the water molecules to create new monomers is known as hydrolysis.
<h3>What is hydrolysis?</h3>
The molecule is broken in a hydrolysis reaction involving an ester bond, such as the one between two amino acids in a protein. As a result, the water molecule (H₂O) splits into two groups: one that forms a hydroxyl (OH) group with the remaining hydrogen proton (H+) and another that transforms into a carboxylic acid.
Practically speaking, hydrolysis refers to the process of separating compounds when water is present.
Condensation, which is the process by which two molecules combine to produce one bigger molecule, can also be thought of as the opposite reaction to hydrolysis. The outcome of this reaction is that a water molecule is ejected by the larger molecule.
The three primary hydrolysis processes are
- Acid hydrolysis.
- Base hydrolysis.

The leaves no longer have water, which means that there is little osmotic pressure which keeps it turgid.
