What is salinity and how does it change?.
A balance between water withdrawn by evaporation and freshwater added by rivers and rain controls salinity. The Mediterranean Sea in Europe has a salinity of 38 parts per million or more. It's nearly cut off from the main ocean, and there's more evaporation than rain or additional freshwater from rivers.

What evidence did Galileo provide to support Copernicus's heliocentric model? Check all that apply.
Galileo determined the shape of each planet's orbit by a mathematical method called triangulation from different
points on Earth's orbit.
Galileo created a model showing the epicycles of the planets, which explained retrograde motion.
Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all
things.
U Galileo explained that people did not see stellar parallax because the stars were simply other suns that are very
far away.
Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.
Intro
Done
Answer:
- Galileo used a telescope to study the moons orbiting Jupiter. This showed that Earth was not the center of all things.
-Galileo discovered the phases of Venus, proving that at least one planet orbited the Sun.
Explanation:
Galileo discovered evidence to support Copernicus’ heliocentric theory when he observed four moons in orbit around Jupiter. Beginning on January 7, 1610, he mapped nightly the position of the 4 “Medicean stars” (later renamed the Galilean moons). Over time Galileo deduced that the “stars” were in fact moons in orbit around Jupiter.
At about the same time, German mathematician Johannes Kepler was publishing a series of laws that describe the orbits of the planets around the Sun. Still in use today, the mathematical equations provided accurate predictions of the planets’ movement under Copernican theory. In 1687, Isaac Newton put the final nail in the coffin for the Aristotelian, geocentric view of the Universe. Building on Kepler’s laws, Newton explained why the planets moved as they did around the Sun and he gave the force that kept them in check a name: gravity.

differences between the three classes of platyhelminthes
Answer:
The phylum Platyhelminthes consist of three different classes: Turbellaria, Cestoda and Trematoda. Class turbellaria is composed of many free-living organisms, while some are parasitic. Trematodes are commonly known as flukes. They are parasitic flatworms with an unsegmented body.
Explanation:
The three classes of Platyhelminthes are Turbellaria, Cestoda, and Trematoda.
What are the differences between the three classes of Platyhelminthes?Flatworms are members of the Platyhelminthes phylum. The Turbellaria, popularly known as planarians, the Trematode, usually known as flukes, and the Cestoda, also known as tapeworms, are the three classes that make up the phylum Platyhelminthes. Flatworm species come in more than 25,000 different varieties.
The four classes of Platyhelminthes are Cestoda (tapeworms), which are internal parasites of many vertebrates; Trematoda (internal parasites of humans and other species); and Turbellaria (free-living marine species).
Thus, these are the differences between the three classes of platyhelminthes.

explain why norepinephrine requires a protein receptor to exert its effects.
Answer:
I'm going off the top of my head for this one, and this is an educated guess, so check it if you would like to. When the norepinephrine binds to a protein, then the protein relays the info to the cells that are required to do the specific action. This is why we feel a sense of stress, elevated heart rates, or high alertness.

Describe how an ecosystem that contains insects, water, algae, and bird work together to provide life.
Answer:
An ecosystem that contains insects, water, algae, and birds all work together by feeding one-another.
Explanation:
Algae are typically found within water. Algae use carbon dioxide, converting water to organic matter and oxygen. They are important sources of dissolved oxygen in a water confine.
Now, since algae help water by oxygenating it, living things are able to drink the water.
..This helps the bird, since it needs to drink water. As all living things do.

1. What is the significance of the specific gravity of the abnormal urine?
Answer:
A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.
Explanation:
Urine specific gravity is a significant and convenient way to measure the abnormal urine. It indicates dehydration or presence of substances in the urine as in case of diabetes.
What is Specific gravity?
Urine specific gravity (USG) measures the concentration of particles which are present in the urine and the density of urine compared with the density of water. Measurement of USG is an easy way and very convenient way to know a patient's hydration status as well as the functional ability of kidneys.
Urine specific gravity falls between the range of 1.002 and 1.030 if the kidneys are functioning normally. However, if specific gravity results above 1.010 this can indicate mild dehydration in that person. The higher the number of specific gravity, the more dehydrated a person may be.
A very high specific gravity means very concentrated urine, which may be due to not drinking enough fluid, loss of too much fluid, or substances such as sugar or protein in the urine.

Environmental resistance includes
biotic/abiotic factors that are
to life.
Answer:
The environmental resistance factors are all the factors or things that keep a population of the organisms from endlessly increasing i.e. keep a check on it. . They reduce the chances for reproduction, affect the health of organisms/individuals, and raise the death rate in the population.
The environmental resistance factors include the factors that are biotic and abiotic.
• The biotic factors are things like a predation, a parasitism, lack of food, competition with other organisms and disease.
• Abiotic factors include factors like drought, fire, temperature, and even the wrong amount of sunlight could affect it.
