Answer:
The correct answer is A. Brief stressors lead to changes in cytokine production.
Explanation:
Cytokines form an important group of proteins that act as mediators of communication between living cells. They can exert their action in a paracrine way (between neighboring cells within the same tissue), or endocrine (between cells located in different tissues). The imbalance on the immune system that stressful events exert is an increase in the production of pro-inflammatory cytokines and their associated spectrum of age-related syndromes and diseases. Proinflammatory cytokines are soluble mediators that promote and mediate inflammatory processes, the following stand out: interleukin 1 (IL-1) is involved in the regulation of the immune process and inflammation; interleukin 6 (IL-6) that also serves as a link between the endocrine system and the immune system; and Tumor Necrosis Factor (TNF), which has the ability to destroy certain cell lines and initiate the cascade of pro-inflammatory cytokines and other mediators.
Continuous microfluidic self-assembly of hybrid janus-like vesicular motors.
- Artificial micro/nanomachines have enormous applications in such as targeted drug delivery, [ 1 ] separation of biomolecules or cells, [ 2 ] surface patterning, [ 3 ] and environmental remediation
- Micro/nanomotor systems that have been investigated include multimetallic and dielectric particles, [ 6 ]bimetallic nanorods, [ 7 ] tubular catalytic microengines, [ 8 ] andcapsule motors
- In the past decade, microfl uidic technology has emerged as a powerful platform for a wide range of applications such as bioanalysis, [ 15 ] tissue engineering, [ 16 ] cellular biology, [ 17 ] and chemical synthesis/assembl
- Microfluidics offers several advantages over conventional batch reaction or assembly, such as continuous and automatic processing, precise control over synthetic conditions, and high reproducibility. [ 19 ] Microfluidic approaches have been used for the assembly of amphiphilic building blocks such as lipids, block copolymers (BCPs), and inorganic NPs into vesicular structures with superior controllability. [ 18a , 20 ] However, to date, there has been no report of continuous micro fluidic synthesis of nano- or micromotors.

Answer:
C) Primary, tertiary and quaternary levels of protein structure
Explanation:
Primary structure; Covalent bond is present in form of peptide bond in the primary structuture of proteins. The amino acids are held together in the polypeptide chain by peptide bond.
Tertiary structure; Disulfide bonds are present between cysteine amino acids, that keeps the parts of polypeptide chain strongly attached to one another.
Quaternary structure; The Quaternary structure of protein is held together by hydrophobic interaction and disulfide bonds.
Sup if u go to enter st and type this is it will give u all information
-3x + 3(2x - 6) = 6
-3x +6x - 18 = 6
3x - 18 = 6
3x = 6 + 18
3x = 24
x = 8
hope this helped, blessing! :)
