Stem tendril provide support to the plant while leaf tendril helping in the formation of food by the process of photosynthesis. Stem tendril is made up of hard and strong fibres to provide rigidity for plant while leaf tendril is made up of soft fibres.
A tendril in botany is a specialized stem, leaves or petiole that is threadlike in shape and is utilized by climbing plants for support, attachment and cellular invasion by parasitic plants. Tendrils don't have lamina or blade but are able to carry out photosynthesis.
In a stem tendril the terminal bud is modified to be tendrils where the growth occurs with the help of axillary bud. This helps the plant body to climb e.g Grape vine and Passion fruit
On the other hand,
In a leaf tendril the entire leaf is modified into a tendril this helps in climbing plants or twining around suitable host. The leaf tendril helps a vining plant to secure itself through possessing a twining growth habit

Glomerular filtration is occurs due to the pressure gradient in the glomerulus. Increased blood volume and increased blood pressure will increase GFR. Constriction in the afferent arterioles going into the glomerulus and dilation of the efferent arterioles coming out of the glomerulus will decrease GFR. This mechanism works in the afferent arteriole that supplies the glomerulus and can regulate the blood flow into the glomerulus. When blood pressure increases, smooth muscle cells in the wall of the arteriole are stretched and respond by contracting to resist the pressure, resulting in little change in flow.

BOD stands for Biochemical Oxygen Demand.
It is the amount of dissolved oxygen required by aerobic biological organisms to break down organic material present in a given water sample at certain temperature over a specific time period. Biochemical oxygen demand (BOD) represents the amount of oxygen consumed by bacteria and other microorganisms while they decompose organic matter under aerobic (oxygen is present) conditions at a specified temperature.

A protein is a naturally occurring, extremely complex substance that consists of amino acid residues joined by peptide bonds. Proteins are present in all living organisms and include many essential biological compounds such as enzymes, hormones, and antibodies. The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain.

A characteristic of any species with only a limited number of possible values shows discontinuous variation . Human blood group is an example of discontinuous variation. ... There are no values in between, so this is discontinuous variation. Continuous variation is the combined effect of many genes (known as polygenic inheritance) and is often significantly affected by environmental influences. Examples of continuous variation include things like a person's height and weight. Examples of discontinuous variation include a person's blood group or the color of a species of bird. These variations can exist for two major reasons.

The continuous process of breakdown and synthesis of biomolecules through chemical reactions occurring in the living cells is called metabolism.
(i) Each of the metabolic reaction results in a transformation of biomolepules.
(ii) Most of these metabolic reactions do not occur in isolation but are always linked with some other reactions.
(iii) In these reactions, the metabolites are converted into another metabolite in a series of linked reactions called metabolic pathways.

Homeostasis is a property of a human biological system where the self-regulating process tends to maintain the balance for the survival. The regulation takes place in a defined internal environment. For example- the presence of glucose in blood plasma, regulation of body temperature, extracellular fluids of an animal despite changes- what the animal has eaten or what it is doing. Every variable is controlled by homeostasis together to maintain life.
In simple terms, it could be referred as a balance in a system to maintain a stable internal environment for the survival of the animal. If the homeostasis regulates successfully, life continues or if unsuccessful, death or disaster occurs.

In the presence of malonate, increase the concentration of the normal substrate and see whether the rate of reaction increases. If it does, malonate is a competitive inhibitor. Malonate is a competitive inhibitor of the enzyme succinate dehydrogenase: malonate binds to the active site of the enzyme without reacting, and so competes with succinate, the usual substrate of the enzyme.en water sample at certain temperature over a specific time period.
