emmasim [6.3K]

Chronic obstructive pulmonary disease (COPD) is the world's top cause of death for the greatest number of individuals, known for its chronic obstructive diseases, chronic bronchitis, and emphysema.

<h3>How genes impact on COPD?</h3>
  • The precise causal process of COPD is still unknown, despite several attempts to discover biomarkers and pathways.
  • In order to better understand the biological mechanism and network module underlying COPD, this study integrates information on biological interactions with information on gene expression.
  • 49 genes were chosen using a sparse network-based technique from the peripheral blood mononuclear cell expression data of 136 participants, comprising 42 ex-smokers and 94 COPD patients.
  • The findings indicate that these 49 genes may have an impact on COPD-related biological functions and molecular processes.

insens350 [35]

Answer:

Movement of particles from a region of high concentration to a region of low concentration

Explanation:

  • Diffusion can be defined as the movement of particles from a region of high concentration to a region of low concentration.
  • Diffusion is a special type of diffusion that involves movement of solute molecules from a region of a high concentration to a region of high concentration until equilibrium is achieved.
  • Diffusion is a passive transport of particles, which means it does not involve use of energy in the form of ATP like the case of active transport.

Madison is experiencing symptoms of paralysis after eating food contaminated by
snow_lady [41]

The consumption of the food contaminated with botulin can make a person experience the symptoms of paralysis. The <em>Clostridium botulinum</em> bacteria produces this toxin, which is also known as botox. It is a neurotoxin which prevents the release of the acetylcholine, which is a neurotransmitter.

Hence, the answer is 'botulin or botox'.
