Answer:
Which of the following mechanisms is used by gram-negative bacteria to cross the blood-brain barrier? D) Inducing TNF
Explanation:
The blood brain barrier is a barrier formed by brain microvascular endothelial cells, astrocytes and pericytes. Pathogens can cross this barrier by using different mechanisms. The Tumor Necrosis Factor (TNF) is the way gram-negative bacteria cross this mentioned blood-brain barrier.
Answer:
Complex Carbohydrates: Also know as polysaccharides (poly = many), these carbohydrates have more than two units of glucose (sugar) linked together. Polysaccharides are generally not sweet and are not water soluble. Starches and dietary fiber are complex carbohydrates.
Complex carbs pack in more nutrients than simple carbs. They're higher in fiber and digest more slowly. This also makes them more filling, which means they're a good option for weight control. They're also ideal for people with type 2 diabetes because they help manage blood sugar spikes after meals.
Simple carbs — also known as simple sugars — contain one or two sugar molecules, whereas complex carbs have three or more. A simple sugar may be a mono- or disaccharide.

<h3>What is sustainability ?</h3>
The main objective of sustainability is for people to live in peace and harmony on Earth for an extended period of time. Specific definitions of sustainability are difficult to agree on and hence vary in the literature and across time
- Sustainability is often represented diagrammatically. The figure at the top of this page suggests that there are three pillars of sustainability – economic viability, environmental protection and social equity.
- Sustainability is important for many reasons including: Environmental Quality – In order to have healthy communities, we need clean air, natural resources, and a nontoxic environment. Growth - UNTHSC's enrollment continues to expand, thus we demand additional resources such as energy, water, and space.
