Answer: True
Explanation: If you have a dominant allele it will show in the phenotype of the organism. To show a recessive allele you need a recessive pair consisting of only recessive alleles

Vaccines are a boon in eradicating various lethal diseases and increase the immunity of the people. The development of vaccines started with the understanding the cell itself, various pathways that regulate its fate. The immunology, a branch of biological science, gave the idea of the working of the defense or the immune system of the body, and of the various specia cells that function for it. This led us to the discovery of antibodies and antigens. Vaciines are artificial means of injecting antigens into the body to generate antibodies beforehand, so that the immune system remembers producing it at the time disease causing agent strikes us.
Thus, we can summarise that STEM research or core science research has led to innovations that have shaped our lives and lifestyle to contribute to an overall good social health.
The two main components of the extracellular matrix are Elastin and Collagen.
The extracellular matrix is an intricate macromolecular network that is found in the extracellular space. The matrix is composed of polysaccharides and very diverse proteins, locally secreted and assembled forming a complex network that surrounds the cells. The matrix is highly developed in connective tissue and its derivatives. The extracellular matrix is formed mainly by proteins, glycosaminoglycans,proteoglycans and glycoproteins, organized in diverse networks that constitute the different tissues. <em>The most abundant proteins are collagen and elastin.</em>
Collagen is a family of very abundant proteins in the body of animals. Collagen molecules can represent 25 to 30 % of all body proteins. Its main mission in the tissues is to form a framework that supports the tissues and that resists the forces of mechanical tension.
The elastin molecules are very close to each other through links between the regions rich in the amino acid lysine. It is an abundant protein in may extracellular matrices and appears as a component of the so called elastic fibers, which are onsoluble aggregates of proteins.
