Answer is
body-brain barrier.
Explanation:
Mannitol injection is used to reduce swelling ande pressure around the brain.
It enhances flow of water from tissues including cerebrospinal fluid and the brain into plasma and interstitial fluid.
Answer:
Covalent bonds form when two atoms share valence electrons,
while Van der Waals forces cause an attraction between nonpolar
molecules
Explanation:
A covalent bond is said to be formed when two atoms of the same or different elements share electrons. In an ordinary covalent bond, each bonding atom contributes one valence electron while in a dative covalent bond only one of the bonding atoms provides the shared pair of electrons.
Van Der Waals forces is the major intermolecular interaction between non polar compounds. Van Der Waals forces " are caused by correlations in the fluctuating polarizations of nearby particles"(Wikipedia).
Embryologically, the space for the development of right lobe is made earlier by the closure of <span>pleuroperitoneal and pleuropericardial membranes, thereby creating more space for the development of right lobe. Molecular stimulation factors are also involved in the process. </span>
The answer is Proteomics.
<u>Proteomics</u> is a discipline of study that involves an examination of proteins and how the proteins encoded by genes interact to produce cell and tissue types.
What is Proteomics?
The extensive study of proteomes is known as proteomics. An organism, system, or biological setting produces a set of proteins known as a proteome. We might speak of an organ or a species' proteome (like that of Homo sapiens) (for example, the liver). The proteome is dynamic; it varies from cell to cell and alterations occur over time. The underlying transcriptome is somewhat reflected in the proteome. However, in addition to the relevant gene's expression level, a number of other factors also affect protein activity, which is frequently measured by the rate at which the processes in which the protein is engaged react.
Proteomics is employed to look into:
- When and where do proteins expressed.
- rates of protein synthesis, degradation, and abundance at steady state.
- how proteins are altered, for as by phosphorylation and other post-translational modifications (PTMs).
- the transfer of proteins among subcellular spaces.
- protein involvement in metabolic processes.
- what interactions proteins have with one another.
