NaBr is a soluble salt. When you dissolve the solid in water it will first separate the íons: Na+ interact and is surrounded by about 6 water molecules, and could be now represented by [Na.6H2O]+, still a positive íon; the Br- will also separate from the Na+ and interact with water molecules (typically 4–6), forming the [Br.nH2O]-, a negative íon.

Suppose a population of 5000 humans were sent to live on Mars. If the humans on Mars
and the humans on Earth are separated for 500 years, will they start to evolve
dierendy? they come back into contact with each other 1.000 years later, is it
made they could have become different species? Explain (Must be 6+ sentences)
Answer:
Yes, this is plenty of time for the humans in Mars to revolve differently. Due to Mars having different features (plants, air quality, etc) the people on Mars may develop differently to aid them in living on a different planet. They may develop a different variation of lungs to help them breathe better. Another possibility is a development that allows them to store water linger due to possible lack of water. In this span of time, humans on Mars may have begun developing these difference tools. As a result, in many years after the humans on Mars could almost be completely unrecognizable to the humans on Earth.

Homeostasis plays a major role in the proper functioning of the body. It is regulated
by different mechanisms such as osmoregulation, thermoregulation, and chemical
regulation by different systems in the body like respiratory system, digestive
system, nervous system, and urinary system.
These systems maintain homeostasis in the human body by -
A releasing a stimulus when hormone levels increase or decrease
B decreasing the movement of blood to organs to maintain heart function
creating more proteins to code for cell repair

which three sentences describe how a wildfire can harm a forest
ecosystem?
Answer:
The wildfires can damage forests that remove carbon dioxide. The wildfires also emit carbon dioxide, and these damaged trees do not have the strength to remove the carbon dioxide from the air. So this causes well-known global warming, which is a bad sign and is harmful to the atmosphere. And on top of that, the wildfires inject soot and aerosols into the air, causing quite complicated effects on the environment's ability to warm and cool on a regular basis.
Wildfires can ruin not just forests, but our world.

Answer:
Explanation:
Distilled water has no contaminants and minerals thus the solute concentration inside the RBC is more than water. Water moves towards high solute concentration, therefore, water will go inside the RBC and burst it. This is why no RBC will be seen.
