During evaporation the sun heats a large body of water causing water vapor. What vapor is a gas. Evaporation is also apart of the water cycle, which evaporation in an important tool in the water cycle.
Remember this:
- When water is heated it turns into a gas.
-When water gets to 0°c water freezes.
-When ice is heated, it turns into a liquid.
Answer:
Through natural selection the disease gain immunity to the antibiotic.
Explanation:
As the antibiotic kills off the members of the population that are not resistant, leaving only the resistant members. These members then reproduce, passing the immunity to their offspring, causing the population to become immune.
Answer:
Matter is conserved because atoms are conserved in physical and chemical processes. As complex as the water cycle is, water molecules are conserved and endlessly recycled in nature. Conservation of mass is a physical law that s never broken.This cycle continues with no loss of water.
As mean arterial pressure increases, <u>the frequency of action potentials from the </u><u>baroreceptors</u><u> increases,</u> informing the medulla oblongata that blood pressure has indeed increased.
- Special receptors called baroreceptors monitor variations in your blood pressure.
- The aorta and carotid sinus both contain significant baroreceptors. The walls of the arteries stretch when the blood pressure in the aorta or carotid sinus rises, stimulating an increase in baroreceptor activity.
- Action potentials are more quickly fired when baroreceptors are activated, with the speed being inversely correlated with the mechanical stretch.
- The brain interprets the information that the baroreceptors send as a rise in blood pressure.
- The blood vessels, heart, and kidneys are just a few of the bodily organs that get signals from the brain to lower blood pressure.

If a zebra mussel is discovered in a lake in Pennsylvania, then the ecologist would be worried because it is an invasive species. The zebra mussel is native to Ukraine and Russia, but if it has been found in Pennsylvania, than it means that it has been introduced in this area. As an invasive species, the zebra mussel can be very dangerous for the native species in the lake. The invasive species usually are more competitive for food sources than the native species, manage to reproduce quicker, bring in diseases, and the native species tend to not have defense mechanisms for them. This leads to rapid decline or even extinction in the native species, while the invasive spreads out quickly and takes over, resulting in dramatic change in the whole ecosystem.
