OSMOREGULATION IN CLAMWORMS
The greater the dilution, the greater the increase in the body weight. The worm tends to accommodate itself to the new environment. After the increase in the body weight, they tend to return back to the normal weight if they are left in the original sea water. These euryhaline osmoregulators are thus capable of surviving in reduced, increased salinity levels. They are found to show two types of blood osmo regulation. First they act as hyper osmotic in the diluted sea water with greater osmo

Adaptation of the body to hot and cold
The heat can affect the protein’s biological processing and this can lead to complication in the health of the human being exposed to extreme heat. The change in the protein configuration of the cell is called “denaturation.” High temperature can alter the nature of protein or kill the cells. If a living cell is exposed to heat above 45 degrees, then burning of the skin occurs.The damage of the skin depends on the duration and intensity of the heat applied to the human body. We, human

Bioinformatics and molecular modelling
The activities of all lipases often rely on the catalytic triad that is usually fromed by the Asp, Ser, and His residues. In the sequence of the amino acid especially involving α/β hydrolases, these three residues often follow the user-Asp-His order. Additionally, lipases often share the consensus sequence defined by the Gly-Xaa-Ser-Xaa-Gly where X may be a residue of an amino acid (Bos and Laxminarayan, 2011; p.The three dimensional structure of any protein molecule often provides valuable

How the eye is suited for the purpose of converting visible light into neural activity and how visual information is then conveyed to the visual cortex
The light first passes through the space between the cornea and the lens that is filled with fluid called aqueous humour. It consequently goes through the t pupil ‘s circular aperture that is surrounded by the iris diaphragm muscles prior to going through the lens (Jones, et al 2004). However, the quantity of light that passes through the pupil is determined by the pupil’s diameter and still goes ahead to be regulated by the iris’s circular and radial smooth muscle fibres. This regulation

Planning research
When different concentrations of sucrose are used, the highest concentration creates a higher concentration gradient that increases the movement of water across the zones as opposed to the experiment with low concentration. When water moves to the plant cell, it swells and becomes rigid because it cannot burst as animal swells that lack a cell wall.The prediction for this piece of experiment is that the visking tube will increase its mass with time because of the osmosis process.
