death. What is this nearly constant number of
organisms called?

According to the article, there are 3,000 brown tree snakes in Guam per square mile (mi2). The average high school in the United States is approximately 121,000 square feet or 0.004 square miles. According to these numbers, how many brown tree snakes would be found in an area the size of a typical U.S. high school?
Answer:
12 snakes
Explanation:
Given
[tex]3000\ snakes = 1\ mi^2[/tex]
Required
Determine the number of snakes in 0.004mi²
Represent this with x;
So, we have:
[tex]3000\ snakes = 1\ mi^2[/tex]
[tex]x = 0.004\ mi^2[/tex]
Cross Multiply
[tex]x * 1\ mi^2 = 3000\ snakes * 0.004mi^2[/tex]
[tex]x * 1 = 3000\ snakes * 0.004[/tex]
[tex]x = 3000\ snakes * 0.004[/tex]
[tex]x = 12\ snakes[/tex]

how can a correlation measure aid the process of predictions
Prediction: Correlations can be used to help make predictions. If two variables have been known in the past to correlate, then we can assume they will continue to correlate in the future. We can use the value of one variable that is known now to predict the value that the other variable will take on in the future.
A positive correlation is one in which variables go up or down together, producing an uphill slope. ... Any type of correlation can be used to make a prediction. However, a correlation does not tell us about the underlying cause of a relationship.

How do you find the altitude of Polaris using Latitude and Longitude?
Answer:
At the Equator (0° of latitude), the North Star is on the horizon, making an angle of 0°. For any point between the Equator and the North Pole, latitude is obtained simply by measuring the altitude of Polaris: at 30°N the star is 30° above the horizon, at 63°N, it is 63° above the horizon, and so on.

explain how ostriches evolved to survive in their environment.
Answer:
Some scientists believe that there were huge fires and the skies were dark and full of pollution due to a meteor exploding and killing off the dinosaurs, and if it's true that this occurred, the Ostrich evolved to be a land animal due to it being too dangerous in the air for them. The long neck may have developed to help them get food that was higher up which is the same speculation for the Giraffe. To stay on land they had to be stronger, bigger, and faster than they were in flight.

#20 = The mitochondria would be most likely to be affected because it's the powerhouse of the cell, provides energy, and imports proteins. I hope this helps.
Explanation:
Which regions of the river in the figure above contain more nutrients than the other regions? Explain.
Answer:
Hello. You don't know what this question refers to, but the regions of the rivers that have more nutrients are those that have a lot of algae and vegetables and few fish and marine animals in general.
Explanation:
The accumulation of nutrients in rivers, mainly nitrogen and phosphorus, stimulates the primary production of this environment, which is represented by the excessive growth of algae and other vegetables, which often end up dominating the entire surface of the river. This is very harmful for aquatic animals as it decreases the oxygen concentration of the river, leading to the death of several animals, especially fish. For this reason, we can say that the areas with the most nutrients in a river will have a large number of algae and a low number of fish.

Plant algea and a group of a bacteria called cyanobacteria are the only organism capable of performing photosynthesis.
Question 3
Which statement below is correct?
A. Photosynthesis produces ATP, and cellular respiration requires light
energy
B. Photosynthesis produces carbon dioxide, and cellular respiration
produces sugars.
C. Photosynthesis and cellular respiration occur in both plant and
animal cells.
D. Photosynthesis produces the oxygen required for cellular respiration.
Answer:
B is the correct answer.
A is incorrect because respiration is always occuring in animals and plants, therefore it means it does not require the presence of light. Photosynthesis does produce ATP, though.
Not C because photosynthesis does not occur in animals
Not D because they both are different processes. They don't really depend on each other, though they could occur at the same time.

Which of the following is a producer?
sunflower
human
cow
mouse
Answer:
A sunflower would be a producer out of the following.
Explanation:
The following people, cow, and mouse are consumers as the sunflower is a producer since it can produce it's own food as the others eat each other to recieve energy.
The following is a producer: sunflower, which is in the first option. Producers are always present at the primary trophic level and take part in the photosynthesis process.
What is the significance of the producer in the ecosystem?A producer in the ecosystem has a significant role, as they play an important role in the ecosystem by producing their own food and later relying others for food and energy. They are also responsible for maintaining the carbon ,nitrogen, and oxygen balance in the atmosphere and maintaining the water balance by absorbing it in the ground and thus raising the groundwater level.
Hence, the following is a producer: sunflower, which is in the first option. Producers are always present at the primary trophic level and take part in the photosynthesis process.
