Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.

I think I've finally figured out the problem with anti-vaccer's
Answer:
Wow. They're both right... I still think Vaccines aren't healthy.
Explanation:
I REALLY DO NEED HELP PLEASE!
Do not spam and do not send out links (those who do will get reported)
Part (a)
Enter the data into your calculator or a spreadsheet. Then perform an exponential regression to find the curve of best fit. This is the closest exponential function we can assign to each population, to measure it's approximate growth.
Let functions f, g and h represent group 1 through 3 in that exact order. You should get these approximate functions:
f(x) = 6830.52397(0.92755)^xg(x) = 3969.81548(1.00295)^xh(x) = 5.67328(1.42775)^xNote: Group 3 doesn't have its population start until 1995, which is 10 years after 1985. This means h(x) only works when [tex]x \ge 10[/tex] or it's meaningless otherwise.
Each function found is of the form y = a*b^x, where 'a' is the initial population (at time x = 0) and b helps determine the growth rate. We set b equal to 1+r and solve for r to get the growth rate.
For f(x), we have b = 0.92755 approximately. Set that equal to 1+r and solve for r
1+r = 0.92755
r = 0.92755-1
r = -0.07245
The negative growth rate indicates we have population decline. Specifically, the rate of decline is about 7.245%
Repeat those steps for the b value of g(x) and you should find that r = 0.00295 meaning we have roughly a 0.295% increase for Mussel group 2.
Group 3 has a growth rate of about 42.775% due to r = 0.42775 in this case. The steps will be the same as for group 1.
=========================================================
Part (b)
The graph is shown below as an image attachment. I used GeoGebra to make the graph, and to also find the exponential regression equations.
We have x as the number of years since 1985, which is the starting point, and y is the population size. Something like (0,4800) means in the year 1985, the population is 4800 mussels (see group 1).
Keep in mind that the green curve for h(x) doesn't make sense for positive x values smaller than 10, due to the fact that the third group wasn't introduced until 10 years after the starting point of 1985.
Also, be sure not to think that the blue g(x) curve is linear. It looks like a flat line, but it's really a very stretched out curve. This is because the growth rate is very small.
=========================================================
Part (c)
It appears that group 3 has caused group 1's population to decline, due to the red points (see part b) going downhill as we move from left to right. This drop-off occurs at around the time group 3 is introduced. Strangely, only group 1 is affected while group 2's population is still increasing. This increase is not much, but it's still a positive growth rate. So it's fairly likely that there are other confounding variables to consider, and it's not entirely group 3 that's causing the trouble.
=========================================================
Part (d)
There are many ways that people impact their environment, whether it's a positive or negative impact. When regarding this topic of marine life, specifically mussels, one way that humans affect the population is what was mentioned earlier: The fact that the third group of mussels was introduced to the habitat. Often, though not always, if you introduce a new species to some environment, then the species of animals already living there may have a hard time coping with the newcomer. The new species would be referred to as "an invasive species". The invasive species is more aggressive at getting food to crowd out the older species that isn't used to the newcomer. This may explain why Mussel group 1 experiences a decline after 1995 when group 3 is introduced. This decline is fairly significant as the graph in part (b) shows. Group 2 doesn't seem to be affected at all since it's growth rate is fairly flat yet steadily increasing even if done slowly. It's possible that group 2 is simply more adapted to deal with competition better than group 1.
Another way humans impact the environment is through pollution. Air pollution may contribute to acid rainfall that would lead to the ocean. There's also chemical pollution such as flushing harmful chemicals down the drain, which also leads to the ocean. This could apply to the average consumer, or to very big industrial companies. For instance, in the news recently in Florida, there was a very big worry that a holding pond could contribute to a spike in algae growth. While algae are beneficial, there are some species that invade more than their fair share of resources and kill off anything else more or less. This is one example where pollution contributes to harmful consequences to unfortunate species who likely die off. On top of pollution, there's general habitat loss that also may explain why group 1 is experiencing a sharp decline (however it wouldn't explain why groups 2 and 3 are growing).
Type the correct answer in the box. Spell all words correctly. What is the name of this ocean? The blank Ocean has the deepest depression in the world, called the Mariana Trench.
Answer:
Pacific Ocean
Explanation:
thats where it is
The Pacific Ocean has the deepest depression in the world, called the Mariana Trench. The Mariana Trench is the deepest part of the world's oceans, located in the western Pacific Ocean.
Explain The Pacific Ocean.The Pacific Ocean is the largest and deepest ocean in the world, covering an area of about 63.8 million square miles and accounting for more than one-third of the Earth's total surface area. It is located between Asia and Australia to the west, and the Americas to the east.
The ocean is known for its diverse marine life, including whales, sharks, dolphins, and various species of fish. The name "Pacific" was given to the ocean by Portuguese explorer Ferdinand Magellan in 1521, who called it "Mar Pacifico," meaning "peaceful sea," due to the calmness of its waters at the time.
However, the ocean is not always peaceful and is prone to natural disasters such as typhoons, hurricanes, and earthquakes due to its location on the "Ring of Fire," a region of intense seismic activity.
The Mariana Trench reaches a maximum depth of about 36,070 feet (10,994 meters) and is located on the floor of the western North Pacific Ocean, east of the Mariana Islands. The trench is crescent-shaped and about 1,550 miles (2,500 km) long, with a width of only 44 miles (70 km). It was named after the Mariana Islands, which are nearby.

Why is RNA necessary for protein synthesis?
Answer:
Ribosomal RNA (rRNA) associates with a set of proteins to form ribosomes. These complex structures, which physically move along an mRNA molecule, catalyze the assembly of amino acids into protein chains. They also bind tRNAs and various accessory molecules necessary for protein synthesis.

Sarah thinks that the number of worms on the sidewalk in front of her house increases after a rainfall. Which would be the best way to test her prediction?
Answer:
To collect data about the population of worms before and after the rainfall.
Explanation:
The best way to test her prediction, we have to wait for the rain and collect the data after the rain and before the rain. The difference between shows the result whether she is right or wrong. In my opinion, she is right because the worms comes out from the soil in order breathe. The rain water block the porous spaces in the soil through which the oxygen enters into the soil and the worms can breather so due to blocking no oxygen for them so they come out from the soil after rainfall.

The
_________.
Answer:

origin
During replication, the two DNA strands separates and each chain serves as a template for a new nucleotide chain. The sites where DNA replication and separation occur are called the origin.
What is DNA replication?DNA replication defines the biological process of making two identical copies of DNA from a single original DNA molecule. It occurs in all living organisms which acts as the most essential part for biological heritage.
During DNA replication, each of the two strands forming the double helix serves as a template from which the new strand is copied, while these new strands will be complementary to the parental or "old" strand. Each new double strand consists of a parent strand and a new daughter strand.
Steps involved in the DNA replication are:
1. Initiation
2. Elongation
3. Termination
Thus, during replication, the two DNA strands separates and each chain serves as a template for a new nucleotide chain. The sites where DNA replication and separation occur are called the origin.

Phytoplankton and algae form the bases of aquatic food webs. They are eaten by primary consumers like zooplankton, small fish, and crustaceans. Then fish get eaten by large predators, such as sharks, tuna, squid and octopus as well as marine mammals like seals and some whales form the top of the food chain. Next a shark is eaten by a whale. These whales have been known to attack and eat everything from small fish and turtles to squid, seals, sea lions, and even large whales. Killer whales also hunt, attack, and eat sharks. That is a food chain from smallest to biggest :)
