By looking at a map, how can you tell where the profile will be the steepest in a topographic map?
Answer:
The contour lines will be closest together.
Explanation:
When contour lines are closer together, the slope is steep. When contour lines are farther apart, the slope is gentle. This is because contour lines indicate altitude. The closer the contour lines, the faster the increase in altitude, and therefore the steeper the slope.
What are the two ways Earth moves? Explain each way.
Answer:The Earth moves in several ways. First, it turns around its polar axis; one turn takes 24 hours. Then it moves along its orbit around the Sun; one full revolution takes 1 year. And third, its polar axis changes direction very slowly, just like a spinning top

You are trying to see who can stay underwater the longest. You stayed under for 48 seconds! When you come up for air, you take a big breath. Your cells need oxygen so they can release energy so you can keep swimming. Explain all the parts of the cell involved in getting oxygen into your cells so it can help release energy.
Answer:
All the parts of the cell involved in getting oxygen into your cells so it can help release energy are Mitochondria , Ribosomes ,Peroxisomes and Vesicles.
Explanation: Explaination of all four parts of the cell involved in getting oxygen into our cells so it can help release energy-
MITOCHONDRIA -:"Mitochondria (singular = mitochondrion) are also referred to as a cell's" powerhouses "or" energy factories "because they are responsible for producing the main energy-carrying molecule of the cell, adenosine triphosphate ( ATP). ATP reflects the cell's short-term stored energy. The method of producing ATP using the chemical energy found in glucose and other nutrients is cellular respiration. This method utilizes oxygen in mitochondria and creates carbon dioxide as a waste product.RIBOSOMES -: The cellular structures responsible for protein synthesis are ribosomes. Ribosomes appear either as clusters (polyribosomes) or single, tiny dots floating freely in the cytoplasm when viewed through an electron microscope. They can be connected to the plasma membrane's cytoplasmic side, or to the endoplasmic reticulum's cytoplasmic side and the nuclear envelope's outer membrane.PEROXISOMES -:Peroxisomes are specialized for the use of molecular oxygen to conduct oxidative reactions. They produce hydrogen peroxide, which they use for oxidative purposes, by means of the catalase they contain, removing the excess.VESICLES -: A byproduct of the transformation of vesicles is oxygen. Also, Prochlorococcus develops a large number of vesicles that are used for many important functions: virus protection, genetic information transfer, and nutrient transmission. Via a number of pathways, all cells generate vesicles.Hence , the parts of the cell involved in getting oxygen into our cells so it can release energy are mitochondria (the main part), ribosomes ,peroxisomes and vesicles.

Explanation:
The water droplets/rain dissolves the fertilizers and make it easier for the plant to suck it.The bacteria present in the roots of the plant takes up the nitrogen and helps the plant to grow.The cow eats the plant and the nitrogen is in the cow's body.After some years the cow dies and its body is eaten up by animals and when it decays, the nitrogen in its body mixes with the earth and thus is taken up by plants and used. The plant gives out air and vapours containing nitrogen through transpiration and other processes which then results in the release and mixing of nitrogen with other gases and thus resulting in rain.Hope you got it... :)

Which information is typically found on a map key?
O location of north
O distance between towns
O names of bodies of water
O highest land elevation in an area
Answer:
A real answer: D
Explanation:
I did the quiz on edg. hope it helped.
The information that is typically found on a map key is the highest land elevation in an area. The correct option is d.
What is a map key?A small informational box called a map key can be found at the bottom of a map. It includes a scale so that you can calculate distance, as well as an explanation of what the various lines and symbols on the map signify.
In maps, there are boxes made on the right or left side of the map. These boxes are given the details of the signs given on the map. For example, a part is red colored on a map. The box will tell what the red color represents on the map.
The highest elevation in an area will be given on the map. The elevation is the height that is changed in many areas, due to mountains and soils.
Therefore, the correct option is d. the highest land elevation in an area.

Organisms require nitrogen to make which of the following?
Answer:
amino acids
Explanation:
All organisms require nitrogen to make amino acids, which in turn are used to build proteins.
Nitrogen is required by living organisms to synthesize amino acids. These amino acids unite to form polymers which make proteins.
What are Amino acids?Amino acids are the organic compounds which contain both the amino and carboxylic acid functional groups in it. This is reason, these acids are called amphipathic acids. Although hundreds of amino acids still exist in nature, by far the most important acids are the alpha-amino acids, which comprise proteins. There are only 22 alpha amino acids which appear in the genetic code.
In the structure of an amino acid, the R represents a side chain specific to each amino acid. The carbon atom next to the carboxyl group is called the α–carbon atom. Amino acids which contain an amino group bonded directly to the α-carbon are referred to as the α-amino acids.

I say A- Older Denser Crust Subduct
As Time pass, Older Crust gets denser. When it reaches the end of its life, it goes under the newer crust. This is called Subduction. (new Vocanoes do form and sometimes erupt)
How does a decrease/decline in a top predator impact biodiversity in an ecosystem?
Answer:
Results in biodiversity loss due to the proliferated growth of prey that feeds on smaller species
Please find the explanation below
Explanation:
In an ecosystem, organisms feed on one another to obtain energy. In this process organisms called CONSUMERS kill and feed on one another in a process called PREDATION. Top predators are those consumers that are found at the peak of the food chain.
A reduction in the number of top predators/tertiary consumers in an ecosystem means that the secondary consumers they feed on (prey) will grow and reproduce beyond control, hence, causing them to pose serious threat to the population of smaller species below them in the food chain.
Therefore, a decrease/decline in a top predator will impact biodiversity by causing it's loss, as organisms in lower level of the food chain will drastically diminish.
