1) Not all of the answers were the same because, everyones heart rate and blood type would be different from each other.

2) Athletes have a low resting heart rate.

3) During blood lost, you'll need a blood transfusion, if you don't know what blood type you have then it's most likely take longer to give you the correct blood type by doing a blood test.

1. Identify a period of time when this population showed exponential growth? Explain how you know this.

2. At what point in time did the population reach its carrying capacity? Explain how you know this.

3. The population's actual growth (in red) often goes above and below the carrying capacity in a cycle, why do you think this happens?

Answers

Answer:

1. 1850

2. it stays on carrying capacity until, about 1835

3. because people are born in generations

Explanation:

1. because the overshoot line grows very quickly around 1850

2. simply an estimate to where i think it lines up

3. once one generation is born, the older one dies.

Answer:

1. Around 1850 is the period of time when the population showed exponential growth.

2. The population reached its carrying opacity technically around 1850 as well but it was much closer to the direct line at around 1870-1875.

3. I believe this happens because of sickness and people choosing to leave the area. (There are many other reasons I am sure you can come up with)

based on
-global warming
- Temperatures
- ocean currents
-Climate

Answers

Answer:

it always going to be hot

Explanation:

Answer: Ice in the North and South Pole triggers the movement of ocean currents by starting a motion called the global conveyor belt. When water freezes in these areas, the water surrounding the newly formed ice decreases in temperature and becomes saltier. This results in an increase in density, so the water sinks to the bottom of the ocean floor where it becomes a cold current. Afterall, the water has to move somewhere so it travels horizontally to spread out over the surface of the earth. Warm water then takes its place and moves to the North. One event such as water freezing in the North and South Pole has resulted in something called the global conveyor belt.

Based on

Answers

Answer for #8:

Cold water is heavier than warm water, and because of that it sinks. Ice dissolving into the water cools the ocean, causing it to drown. This creates a wave by which cold water is drowning near the poles, which forces the water into the depths of the ocean, leading the entire ocean to swirl. This cold, thick water is then forced back up against the west shores of the continents where it can be warmed.

Paramecia that live in freshwater have contractile vacuoles, while those that live in salt water do not. Why do you think this is the case?

Answers

Answer:

water enters by osmosis, vacuole is used to pump out excess water.

Explanation:

Paramecia that live in freshwater would have contractile vacuole because they will need to get rid of excess water unlike those that live in salt water.

The vacuole primarily functions to get rid of excess water from the cell.

Freshwater is hypotonic to the cytosol of paramecia. Thus, water will always enter the paramecia cells by osmosis. If the excess water is not excreted from the cell, turgidity will result and the cell may burst.

On the other hand, salt water is likely hypertonic to paramecia cells. Thus, instead of having vacuoles for water excretion, a mechanism would have to be put in place so as not to lose too much water to the surrounding salt solution. In other words, a vacuole would be totally redundant in the hypertonic solution.

Need this for homework
1.What happens when fertilizer ends up in waterways?
2. Describe eutrophication.
3. What has happened at the mouth of the Mississippi River?

Answers

Bxnzjsbdmsgdjcdpdjxjdk
1. When fertilizer ends up in waterways, the fertilizer gets carried to larger bodies of water. The added nutrients from the fertilizer creates excessive growth of algae, creating algal.

2. Eutrophication is what a water based ecosystem does when too much nutrients are added to it. it’s mainly caused by two nutrients, phosphorus and nitrogen. The biggest problem in eutrophication are algal blooms.

3. At the mouth of the Mississippi River there is a dead zone. Due to algae using up all the oxygen, aquatic organisms can not survive there. Things that can help prevent dead zones are cutting down on fertilizer use and preserving wetlands.
