They migrate though the North Atlantic Ocean. And also they migrate from North America,Europe,Iceland,and northwestern Russia.
Most people in the world get our water from rivers and lakes, including the vast majority of the world’s poorest people.
But half of the world’s 500 most important rivers – water sources for hundreds of millions of people – are being seriously depleted or polluted.* Approximately 40 percent of the rivers in the U.S. are too polluted for fishing and swimming.**
Water shortages will likely be a fact of life for most people on the planet within the next ten years.*** We can’t afford to pollute and destroy our drinking water sources. But that’s exactly what we’re doing – often without knowing it.
Forests, grasslands and wetlands are nature’s water filters. They help keep erosion and pollution from flowing into our waters and they slow rainwater down, sending more water into underground supplies. But every year we lose 32 million acres of forest – that's a lot of water filters, gone, every year.
We are facing dirtier, unsafe water and more risk of water shortages and scarcity. This crisis is real, it’s happening now and it’s getting worse fast.
The Nature Conservancy partners with people communities in all 50 states and 30 countries to protect water sources. We work on the ground to:
<span><span>Prevent deforestation and destruction of grasslands – nature’s water filters</span><span>Restore forests and grasslands that have already been lost or damaged and sending erosion into our waters</span><span>Equip farmers with practical ways to keep harmful run-off out of our waters</span><span>Restore floodplains that act as sponges and send water down into groundwater supplies and filter pollution out of rivers</span><span>Create new science that helps pinpoint the greatest threats to our waters and the most effective ways to combat them</span></span>
But we understand that nature won’t solve everything, so we’re finding new ways to reduce water use. More than 70 percent of water withdrawn from nature goes to agriculture, so we’re helping farmers access new technologies and practices that use less water while continuing to produce the food we need.
For the Data and Observation refer the image attached.
Data Analysis:
Calculate the percentage of the cell cycle spent in each stage.
Number of cells in given stage ÷ total number of cells counted × 100 = % of the cell cycle spent in this stage
Conclusion:
Be sure to answer the following reflection questions in the conclusion of your lab report:
Based on your data, what can you infer about the length of time spent in each stage of the cell cycle?
The most time is used in the cell cycle is in the interphase.
What stages were the longest and shortest? Give a brief explanation of why these stages may have that time period.
The longest phase of the cell cycle is the Interphase. Most of the total time of cell cycle is spent in the Interphase. The reason for this being is that the cell prepares itself for its division, and also in this phase, the necessary protein for the duplication of organelles occurs.
True??? I think u don’t need to put the answer I gave u but it’s just my thought
The best and most correct answer among the choices provided by the question is the fourth choice. The organisms survived in high and low salinities because of the t<span>emperature fluctuations can cause changes in the salinity levels of the water. </span>I hope my answer has come to your help. God bless and have a nice day ahead!
