Structural Organisation in Animals and Plants

Molecular Weight

A molecule’s weight is the sum of the weights of the atoms that make it up. The unit of weight is the dalton, which is one-twelfth the weight of a 12C atom. Water’s molecular weight (MW) is, thus, 18 daltons. Because different isotopes of an element are present in different molecules of the same compound, […]

Phylum Protochordata

The phylum family comprises different species having different habitats. Many of these species follow the ground-level living style, and some depend on their host to reach their adult stage. Most of the species in this family lead marine life, either in freshwater or salty seawater. This is because water life is a safe option for

Secondary protein structure

A polymer of amino acids connected by peptide bonds is referred to as a protein structure.  Protein structure is when the peptide backbone of the protein structure will fold into itself, to give proteins their unique shape. This folding of the polypeptide chains happens due to the interaction between the carboxyl groups along with the

Vertebrates Classification

Introduction The term vertebrate refers to the spine’s joints. These animals’ spines or backbones are made up of discrete pieces called vertebrae that are connected by movable joints. Vertebrates emerged over 530 million years ago during the Cambrian epoch. From the Polar Regions to the Tropics, this subphylum, or sub-division, contains species. They range in

Vertebrates

The existence or absence of vertebrates is one of the ways life is characterised. Vertebrates and invertebrates are thought to have descended from a common ancestor that lived roughly 600 million years ago. True vertebrates first appeared 525 million years ago, and since then, they have evolved into a vast lineage which contains armoured fish

Venom and Poison

The majority of individuals are unaware of the distinctions between venom and poison. They are not, however, the same thing. Both are poisonous poisons, but they are administered to victims in distinct ways. They are biologically produced substances that have an impact on an organism’s normal functioning. Venom and Poison Although the words “venomous” and

Uncompetitive inhibition

While uncompetitive inhibition necessitates the formation of an enzyme-substrate complex, non-competitive inhibition can occur with or without the presence of the substrate in the reaction. Uncompetitive inhibition is distinguished from competitive inhibition by two observations: first, uncompetitive inhibition cannot be reversed by increasing [S], and second, as shown in the Lineweaver–Burk plot, parallel lines rather

Types of Carbohydrates

Bread, beans, milk, popcorn, rice, potatoes, biscuits, chapati, soft drinks, and cherry pie are just a few carbohydrate-rich foods. Carbohydrate-dense meals are an essential component of a healthy diet. Carbohydrates give the body glucose, converting it into energy for biological and physical tasks. Eating carbohydrates from nutritious meals is more important than following a strict

The Ventral Nerve Cord

The kingdom Animalia developed from the phylum Porifera, which involves sponges. The nervous system is not differentiated in such a manner in invertebrates. Invertebrates include the phylum Porifera to the phylum Echinodermata. Invertebrates possess the ventral nerve cord. The ventral nerve cord has two ganglia connected to the brain to coordinate neural signals. The ventral

The scientific name of tiger

The scientific name of the tiger is Panthera tigris. Tigers (Panthera tigris) are the most dominant and largest of all cats. Despite their size, they are highly agile. Tigers can leap between 26 and 32 feet in a single bound. Their distinctive orange coat, black stripes, and white markings make them one of the most
