Answer:
It means one trait does not influence the expression of the other. Example is given in the explanation section.
Explanation:
A trait is the phenotypic characteristics an organism possesses. It is determined and controlled by genes. According to Mendel, an organism receives two forms of every gene called ALLELE. Each allele of a gene encodes a different trait.
Mendel, in his law of independent assortment stated that the inheritance of a trait encoded by the alleles of one gene does not influence the inheritance of another trait encoded by the alleles of another gene. A trait is said to be independent of another if it doesn't influence the expression of the other trait.
An example is the seed colour and seed shape trait in a plant. The seed colour trait is encoded by a certain gene and its expression and inheritance is independent of the seed shape trait encoded by another gene.
Calcium ion is responsible for Muscle Contractions.
Red Blood Cell: Binds and carries Oxygen
White Blood cell: Fights pathogens that can cause sickness
Platelet: Helps in the healing of cuts and wounds
Plasma: Contains the liquid portion of blood
The right option is; a. fatty substances called lipids inside the cell
Among other changes caused by cell aging, there is an increase in pigments and fatty substances called lipids inside the cell.
Aging occurs in the body's cells, tissues, and organs and it therefore affects the functioning of all body systems. Cell aging makes cells sizes to increase and reduces their ability to reproduce. It causes an increase in pigments and fatty substances (lipids) inside the cell. This makes the cells to be inactive or to function abnormally. Aging also causes the accumulation of waste products in tissues.
Answer:
The correct answer is: Hydrophobic, Hydrophobic.
Explanation:
- Proteins are made up of polypeptide chains which are formed by the polymerization of amino acid molecules, linked together by peptide bonds.
- The amino acids can be broadly classified into non-polar and polar.
- The non-polar amino acids can be defined as those amino acids whose side chains possess hydrocarbon molecules only. They do not possess any charge and are incapable of forming hydrogen bonds with water molecules. They tend to avoid water and so they tend to remain buried into the interior of a protein. Examples can be illustrated as Leucine, Valine, Isoleucine, Phenylalanine, etc.
- The polar amino acids can be defined as those amino acids whose side chains either possess a charge (positive or negative) or a hydroxyl group which is capable of forming hydrogen bonds with water molecules. As they tend to form hydrogen bonds with water molecules they are usually found on the surface of the proteins. Examples can be illustrated as Lysine, Arginine, Serine, Asparagine, etc.
