Homozygous Definition Homozygous is a genetic situation in which a person inherits the same alleles from both parents for a gene. Both alleles are dominant or recessive in homozygous chromosomes. Two capital letters (XX) denote the dominant trait, while two lowercase letters denote the recessive trait (xx). Homozygous-dominant chromosomes have two copies of the dominant … Read more
Table of Contents Definition of Lipids Lipids are a diverse collection of chemical molecules that are soluble in non-polar organic solvents but insoluble in water. They are employed as cell membrane components, energy storage molecules, insulation, and hormones in most plants, animals, and microbes. Lipids Characteristics At room temperature, lipids can be either liquids or … Read more
What is Diploid? A cell or creature that is diploid has two sets of chromosomes, one from each parent. Somatic cells are diploid in most organisms, whereas sex cells are usually haploid. The two chromosomes obtained from two parents are duplicated twice in diploid cells. Except for a few rats, almost all mammals are considered … Read more
Glycolysis Definition Glycolysis is the main pathway for glucose catabolism, in which glucose (6-carbon component) is transformed to pyruvate (3-carbon compound) in a ten-step process. Glycolysis is the initial stage in the glucose metabolism process in both aerobic and anaerobic organisms. The mechanism of control and the following metabolic destiny of the pyruvate generated at … Read more
Definition of Voluntary Muscles Voluntary muscles are those that can be moved by a person’s free will and are virtually always linked to the skeletal system. These muscles are responsible for all types of motions in vertebrates and are connected to the bones via tendons. Voluntary muscles make up around 40% of the body’s total … Read more
What is Celsius scale ? The Celsius scale, sometimes known as the centigrade scale, is a temperature scale based on water’s freezing point of 0°C and boiling point of 100°C. In 1742 A.D., Swedish astronomer Anders Celsius introduced the scale, which was also named after him. The sign for this scale is °C. The Celsius … Read more
Phenotype Definition In genetics, phenotype refers to all observable features in organisms that are the outcome of the genotype’s interaction with the environment. Phenotype is derived from the Greek word pheno, which meaning “observation.” Phenotypes are used to describe observable features in animals such as height and colour. A phenotype describes an organism’s morphology, physical … Read more
Definition of Cladogram The graphical representation of the potential relationship (phylogenetic relationship) between distinct groups of species is called a cladogram. It is used to discover the evolutionary link between organisms through phylogenetic analysis. The cladogram is made up of the Greek words clados and gramma, which represent “branch” and “characters,” respectively. Only the topography … Read more
The animal kingdom has been isolated into two subgroups: Vertebrates and Invertebrates. The vertebrate column which is also referred to as the backbone is present in some animals, those animals are known as vertebrates. Those animals that do not contain backbone or vertebrate column are known as invertebrates. What is Invertebrate ? Invertebrates can be … Read more
Vacuoles Definition: A vacuole is a film-bound organelle that is available in all plant and contagious cells and some protist, creature, and bacterial cells. The most prominent compartment in most plant cells is an extremely huge, liquid-filled vacuole. Huge vacuoles are likewise found in three genera of filamentous sulfur microorganisms, the Thioploca, Beggiatoa, and Thiomargarita. … Read more
