Blood-Brain Barrier prevent material from moving in or out of the brain's capillaries.
What is blood-brain barrier?
- All of the body's tissues and organs depend on blood arteries to carry oxygen and nutrients to them.
- The blood-brain barrier, a special property of the blood arteries that vascularize the central nervous system (CNS), enables these vessels to tightly control the transit of ions, chemicals, and cells between the blood and the brain.
- Correct neuronal function is enabled by the careful regulation of CNS homeostasis, which also safeguards neural tissue from toxins and infections.
- Alterations to these barrier qualities play a significant role in the pathophysiology and development of various neurological illnesses.

<h3><em><u>Prokaryotes</u></em> play several roles in the nitrogen cycle.

Answer: 1: Environmental effects
2: High Cost
Explanation:
1 Environmental Effects
Power farms on shore that are visible from land may cause conflicts with tourism and local acceptance. Due to this, coastal installations and facilities on land has to meet higher restrictions in terms of size and location.
We don’t yet know exactly how wave power affects sea life. We will hopefully in the next following years have more data in this area.
2 Costs
Wave power is in very early stages of development, which makes speculating on costs harder. Wave resources, connections to the power grid and the lifespan of the technology are just a few factors that result in different costs for different projects. Of these factors, the lifespan is the most uncertain one, since this is a relatively new technology and we are lacking data on how long these wave power inventions realistically can operate.
At the moment, the costs of wave power are generally very high. These power plants cannot be developed without sufficient funding from the governments. On the other hand, renewable energy is the future, and the costs are expected to drop when larger facilities are up and running.
Many of the parts that are involved in wave power generation require regular maintenance. The fact that some of these parts are under the water does not make it any easier – or cheaper for that matter.

Answer: The correct answer is (a)Spring and fall when warm and cold water mixes
Spring and fall when the warm and the cold water mixes and the mixing of water evenly distributes the oxygen present in lake. During winter the cold water is below the ice and the different areas of lake have different concentration of dissolved oxygen. In summer the warm water lies above the cold water, here also the concentration of dissolved oxygen varies.
Hence, during spring and fall the warm water and cold water mixes which evenly distributes the dissolved oxygen present in lake.
