Mepolizumab and reslizumab improve asthma control by binding to

<span>Both Mepolizumab and reslizumab bind to interleukin-5 (IL-5), a key cytokine responsible for the differentiation, maturation, and activation of human eosinophils. Both antibodies bind to IL-5 and prevents binding to the interleukin 5 receptor alpha subunit, on the surface of eosinophil white blood cells. When these antibodies bind to IL-5, they stimulates B cell growth and increases immunoglobulin secretion, and this reduces the survival of eosinophils. Eosinophils, along with basophils and mast cells, are important mediators of allergic responses and severe asthmas.</span>

Interleukin-5 (IL-5). IL-5 is responsible for the recruitment and maturation of eosinophil. Eosinophils on the other hand are majorly involved in the inflammatory response in asthma- characterised by narrowing of the airways. Mepolizumab and reslizumab are, therefore, anti-IL-5

Answer:

osmosis is the movement of water molecules from a region of lower concentration to a region of higher concentration through a semi permeable membrane

Explanation:

note: osmosis only occurs in liquids

and a semipermeable is a membrane with very tiny holes that allows solvent molecules to pass through it readily but does not allow solute particles to pass through it

This sample is naturally occurring, inorganic, solid, has a square crystal structure, and a definite chemical composition (NaCl)

Alika [10]

Answer:

A Mineral is defined as an inorganic, naturally occurring, homogenoussolid, with a definite chemical composition, and ordered (crystalline) atomic structures.

Explanation:

Inorganic: Involving neither organic life nor the products created from or by organic life.

Naturally Occurring: Must be formed by natural processes, meaning a mineral cannot be manmade, manufactured, or created in a laboratory.

Homogeneous Solid: A mineral must be chemically and physically uniform down to the atomic level.

This homogeneity means that the mineral will have absolutely predictable physical properties

including hardness, density, and streak.

Definite Chemical Composition means that all occurrences of that mineral have a chemical

composition that varies within a specific limited range and the atoms that make up the mineral must

occur in specific ratios.

Ordered Atomic structure (Crystalline): The atoms in a mineral are arranged in a systematic and

repeating pattern. Glasses such as obsidian, which are disordered solids, liquids (e.g., water,

mercury), and gases (e.g., air) do not have a crystalline structure and are therefore not minerals.

Which of these organisms is a part of the group that produces all of the available energy in a food web

shusha [124]

the best organism for that would be grass because it collects water and sun energy and shares the energy with other organisms.

hope this helps you good luck.!!!!

How are oxygen and carbon dioxide exchanged between the alveoli and the

Lorico [155]

Answer:

B. Osmosis

Explanation:

Osmosis is the process in which oxygen and carbon dioxide exchanged occur between the alveoli and the capillaries because the oxygen enters the body and the carbondioxide gas leaves the cell through a semi-permeable membrane and we know that Osmosis is a process in which smaller molecules moves from higher concentration to lower concentration through semi-permeable membrane of the cell.
