Answer:
There are two types of melanin--eumelanin and pheomelanin. In general, the more eumelanin in your skin, the darker your skin will be. People who make more pheomelanin than eumelanin tend to have lighter skin with freckles. Like many other traits, the amount and kind of pigment in your skin is controlled by genes
Explanation:
why the numerical values on the X and Y axis has to be consistent?
Answer:
Each axis needs a scale to show the range of the data on that axis. The low end of the scale may be zero or a round number value slightly smaller than the smallest data point. The high end of the scale is usually a round number value slightly larger than the largest data point. The scale is measured off in major and minor tick marks. Typically the scale runs from low to high in easily counted multiples like 10s, 50s, 100s, etc. When graphs are compared side-by-side, consider scaling them to the same data range to make comparisons easier.

Explanation:
Distinguish between the different ways volcanoes cause damage.
Answer:
Hi! Your answer is:
The volcanic plume of an eruption is the pyroclastic flow which sends large amounts of ash and rock into the air and along the ground surrounding the volcano. When this ash and rock mixes with water it forms lahars which flows down the slopes of volcanoes like a landslide, clearing everything in its path. The rocks thrown into the air by the pyroclastic flow, tephra, fall to the ground causing damage where they strike. Toxic gases released through fumaroles can result in acid rain, air pollution and can deplete atmospheric ozone. And of course molten rock emitted from volcanoes as lava flows in streams down volcanoes destroying vegetation and property wherever it touches.
Explanation:
Volcanoes emit deadly gases, ash, lava, and rock. Volcanic eruptions kill. Floods, mudslides, power outages, drinking water poisoning, and wildfires can follow volcanic eruptions, posing health risks.
What are volcanoes?The pyroclastic flow that results after an eruption of a volcano is known as the volcanic plume. This flow transports significant quantities of ash and rock into the air and along the ground in the area surrounding the volcano. When this ash and rock combines with water, it generates lahars, which are similar to landslides and rush down the slopes of volcanoes like a river, sweeping away everything in their path.
When they hit the ground, the rocks that were thrown into the air by the pyroclastic flow, known as tephra, cause damage to the area where they land. Toxic chemicals that are emitted by fumaroles have the potential to cause acid rain, contribute to air pollution, and reduce the amount of ozone in the atmosphere.

The zika virus was first identified in Uganda in 1947. The virus is transmitted from person to person by a bite from a mosquito. It is commonly carried by the Aedes mosquito which is prevalent throughout Central Africa. The virus has more recently spread to the Americas (South, Central, and now North) and is expected to spread to Europe. There is a concern that the virus may reach epidemic proportions. Zika virus is related to yellow and dengue fever. Common symptoms are low grade fever and a distinctive skin rash and other symptoms include vomiting, headache, and muscle and/or joint pain. Pregnant women should avoid traveling to areas known to have zika virus present because the virus is known to cause microcephaly and developmental difficulties related to the central nervous system. Based on the paragraph above, class discussions, and other VALID (be careful with your selection of e-materials! CDC – Center for Disease Control is a good place to start) sources of information please answer the following questions. State a reason why the virus has spread to the Americas and likely to spread to Europe. Define the term microcephaly. What bones of the fetal skull would be affected by zika? Specifically, what area of the CNS is not fully developed in microcephalic individuals. In 1 -3 sentences describe the developmental difficulties of microcephalic individuals. How does one know if they have contracted zika? Do men need to be concerned about contracting zika? How does one avoid contracting zika? In a short paragraph (2-5 sentences!) provide one example of a scientific measure that could possibly control the spread of zika and explain how the measure works (controls the spread).
Answer:
1.Most people infected with the Zika virus have no signs and symptoms, while others report mild fever, rash and muscle pain. Other signs and symptoms may include headache, red eyes (conjunctivitis) and a general feeling of discomfort. Zika virus is also called Zika or Zika virus disease. 2.The frontal and parietal bones, but not the occipital bone, collapse over the injured brain. Almost all of the children had prominent calcifications in the brain. Unlike in children infected with cytomegalovirus, periventricular calcifications are the exception in children infected with Zika virus. 3.No they should not be worried.

Chemical Oceanography
Biological Oceanography
Answer: Oceanography is the study of all aspects of the ocean. Oceanography covers a wide range of topics, from marine life and ecosystems to currents and waves, the movement of sediments, and seafloor geology Geological oceanography is the study of Earth beneath the oceans.
Physical oceanography is the study of physical conditions and physical processes within the ocean, especially the motions and physical properties of ocean waters. Physical oceanography is one of several sub-domains into which oceanography is divided. Others include biological, chemical and geological oceanography.
Chemical oceanography is a broad and complex study of the metamorphosis that the chemicals within oceans, living marine organisms, and the ocean floor undergo. The ocean contains a multitude of chemicals; some are natural, and others are man-made. These chemicals enter the sea in a number of ways.
Biological oceanography is a field of study that seeks to understand what controls the distribution and abundance of different types of marine life, and how living organisms influence and interact with processes in the oceans.

Answer:
According to an April study, table corals (Acropora hyacinthus) can adapt to resist bleaching in warmer waters. On Ofu Island in American Samoa, A. hyacinthus lives in both hot and cool pools. In the lab, researchers tested corals from both environments to see how they reacted to increased heat.
Explanation:

Some scientists today believe that adaptations are more caused or provoked by the fact of competition.
What is meant by Adaptation?Adaptation may be defined as the process that significantly involves the modification of internal and external attributes of organisms that makes them fit for survival and reproduction in the natural environment.
Competition is because of the fact that as the diversity of organisms increases, the resource limits remarkably enable the organisms to activate the mechanism of competition. Due to this, each and every species makes itself superior in order to make their survival in the natural environment.
Therefore, some scientists today believe that adaptations are more caused or provoked by the fact of competition.

When a patient comes to a hospital with severe dehydration, doctors will give
them an IV filled with a salt-water solution called saline, which is isotonic with
the body's blood cells.
Why is the patient not given pure water?
Answer:
The red blood cells could burst.
Explanation:
If they are given pure water, the IV fluid will be hypotonic to the blood cells. That means water will end the red blood cells by osmosis, from a high concentration outside to a lower concentration inside.
This will result in the red blood cells becoming swollen and even potential bursting.
