Answer is 55%.
Blood is fluid connective tissue that consists of two main components, plasma and formed element. Blood plasma is a clear extracellular fluid, which is a mixture of proteins, enzymes, nutrients, wastes, hormones and gases. Formed elements are made up of the blood cells (red blood cells and white blood cells) and platelets. All formed elements are cells except for the platelets, which are tiny fragments of bone marrow cells.
The formed elements can be separated from plasma by centrifuge. On separation of blood components, it is evident that formed elements make up 45% of total blood volume while the plasma makes up 55% of the total volume.
Answer:
D) Competition between organisms
Explanation:
Random mating between organisms, absence of any factor of evolution (mutation, recombination, gene flow, migration etc.) and a large population size serve to maintain the allele frequency and thereby the phenotype frequency over generations. However, competition between organisms for any natural resource leads to natural selection of "better competing organisms" and increases their phenotype frequency in the population.
