Answer:
c.) Its density is greater than the density of freshwater.Explanation:
Seawater is denser than both fresh water and pure water because the dissolved salts increase the mass by a larger proportion than the volume.
The freezing point of seawater decreases as salt concentration increases.
Answer:
C.) Its density is greater than the density of freshwater.
Explanation:
Average density at the surface is 1.025 kg/l. Seawater is denser than both fresh water and pure water (density 1.0 kg/l at 4 °C (39 °F)) because the dissolved salts increase the mass by a larger proportion than the volume. The freezing point of seawater decreases as salt concentration increases.

how are evolution and allele frequency related
Answer:
Evolution is a process that causes an acceleration in genetic change within a population. Allele frequency is the measure of frequency of a certain allele within a population. Allele frequency is an indication that evolution is occurring because a change in allele frequency means a change in the genetics of a population. Also, evolutionary change can’t happen without changes in the allele frequency.

What process would allow the molecule to move into the cell?
Answer:
diffusion
Explanation:
Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
Compare and contrast a fossil and a trilobite.(1 point)
A (Both fossils and trilobites are relativity new, both being around 1,000 years old. However, fossils are only found under water, whereas trilobites are found all over the globe.
B (Both fossils and trilobites are relativity new, both being around 1,000 years old. However, trilobites are only found on the bottom of the ocean, whereas fossils are found only on land.
C (Both fossils and trilobites are extremely old. However, a fossil was a creature that was living on Earth at some point that over time turned into a trilobite, meaning a fossil is one type of many different types of creatures found in trilobites.
D (Both fossils and trilobites are extremely old. However, a trilobite was a creature that was living on Earth at some point that over time turned into a fossil, meaning a trilobite is one type of many different types of creatures found in fossils.

Answer:
D. Both fossils and trilobites are extremely old. However, a trilobite was a creature that was living on Earth at some point that over time turned into a fossil, meaning a trilobite is one type of many different types of creatures found in fossils.
Both fossils and trilobites are extremely old. However, a trilobite was a creature that was living on Earth at some point that over time turned into a fossil, meaning a trilobite is one type of many different types of creatures found in fossils. So, the correct option is D.
What do you mean by Fossil?Fossils are the preserved remains of the organisms whose bodies were buried in the sediments, such as sedimentary rocks.
Trilobite is a member of a group of extinct fossil arthropods easily recognized by their distinctive three-lobed and three-segment forms. It is exclusively a marine animal. It first appeared at the beginning of the Cambrian period.
Therefore, option (d) significantly compares and contrasts a fossil and a trilobite.

which policy would most likely decrease a city's gasoline use
Make sure the gas cap is on tight. One reason you may not be getting the mileage you expect is because there isn't as much gas in your tank as you think. 147 million gallons of gas were lost last year due to evaporation. Why did it evaporate? The gas cap was not on tight. So just make sure it is tight, and it will enable you to keep all the gas you pay for
The cost-effective policy will be deemed the most beneficial in reducing the use of gasoline in cities.
What is policy of cost effectiveness?A cost-effective policy focuses on both the cost and the quality of the product. The use of gasoline can be reduced by improving the technologies in vehicles where the engine consumes less gasoline.
Aside from that, by introducing new vehicles with comparable fuel consumption, consumers will be diverted from gasoline to other fuel-based vehicles with efficient output.
The government can also raise gasoline prices, but this has a negative impact on people's financial stability, resulting in a decrease in gasoline consumption.
Thus, this policy would most likely decrease a city's gasoline use.

What type of air mass forms over Orlando FL
Maritime tropical air mass forms over Orlando FL.
What do you mean by Air mass?Air mass may be defined as a large volume of air in the atmosphere that is mostly constant in temperature and moisture.
A Maritime tropical air mass is associated with warm, humid weather and thunderstorm. This type of air mass is most commonly found in the United States during summer months.
It also reduces the intensity of sunlight during winter months and hence temperature declines.
Therefore, maritime tropical air mass forms over Orlando FL.

A 0.1-kg block of aluminum was heated to a temperature of 80°C. It was then placed into 0.5 kg of water with an initial temperature of 20°C. Which statement best describes the initial interaction between the aluminum block and the water?
Answer:
The aluminum block will transfer heat to the water quickly, by conduction.
Explanation:
Aluminum is an excellent temperature conductor, which means that it can absorb heat very quickly, as well as transfer heat just as quickly. In this case, when the aluminum block is heated to 80ºC, the molecules in that block move quickly and start to collide with each other, releasing heat to the surrounding environment. When this aluminum bar comes in contact with water that has a temperature of 20ºC, the moving molecules of the aluminum bar release heat to the water that heats up, while the aluminum bar loses heat, decreasing its temperature. This temperature transmission will take place until the water and the aluminum bar have the same temperature

How do the organ systems function together in the human body?
Answer:
Some body systems work together to complete a job. For example, the respiratory and circulatory systems work together to provide the body with oxygen and to rid the body of carbon dioxide.
