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.
what are the similarities and differences between water and glucose?
Answer:
See the answer below
Explanation:
Both water and glucose contain hydrogen and oxygen. However, glucose has carbon in addition to the two elements. A molecule of glucose has 6 carbon, 12 hydrogen, and 6 oxygen atoms while a molecule of water has just 2 atoms of hydrogen and one atom of oxygen.
Both glucose and water are polar molecules.
Water is liquid at room temperature while glucose is a solid at room temperature.
In terms of structures, the overall structure of water is bent while that of glucose may be alpha or beta 6 carbon ring structure.

i am not good at bio aka life so i need help with 19 and 20
Answer:
#19 = The cell is an animal cell because it's missing the organelles required in plant cells(chloroplast, vacuoles, and the cell wall)
#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:
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.
Explanation:
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]

Many coniferous forests containing pine trees grow in the taiga, the largest habitat in the world. Using credible sources, such as NASA, research the typical climate conditions in coniferous forests. Explain why the structure of pinecones helps ensure successful reproduction in coniferous forests.
Answer:
Precipitation in coniferous forests varies from 300 to 900 mm annually, with some temperate coniferous forests receiving up to 2,000 mm/ year (79 in/year). The amount of precipitation depends on the forest location. In the northern boreal forests, the winters are long, cold and dry, while the short summers are moderately warm and moist. In the lower latitudes, precipitation is more evenly distributed throughout the year.
The climate conditions of coniferous trees normally have summer temperatures that range from -40°F to 68°F with seasons ranging with an average of cold, long, snowy winters, and warm, humid summers. With defined 4 seasons, and at least 4-6 frost-free months. The precipitation has about 12 to 35 inches of rain each year. The in these areas of course the vegetation they have is coniferous trees, but the main dominant trees are pines, spruces, firs, and larches. With mosses, liverworts, and lichens covering the main ground.
Which word describes the water stored below Earth's surface?
floodplain
groundwater
kettle
sinkhole
Answer:
ground water
Explanation:
kettle is a thing that holds water and is used to boil it, a food plain is a field in which we grow crops on, and a sink hole is when the earth collapses on its self, therefore by using the process of elimination you can see that it is groundwater, also it's s of explanatory because of the name
Groundwater is the water found below the Earth's surface in geological reservoirs known as aquifers.
What is groundwater?It is the one that is found under the earth's surface, that is, the set of water that is stored in depth and occupies the pores and fissures of the most solid rocks.
On Earth, much of the water is found in aquifers that are located below the planetary surface, these are geological-type formations that store groundwater.
Therefore, we can conclude that groundwater is that body of water that is stored deep or below the earth's surface.

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.

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.

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.

Explanation:
Identify the structures a virus can contain.
Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
