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. The lungs provide a place where oxygen can reach the blood and carbon dioxide can be removed from it. Some body systems share a common organ that performs more than one job.

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

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.

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.

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.

Maritime tropical air mass forms over Orlando FL.

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.

The cost-effective policy will be deemed the most beneficial in reducing the use of gasoline in cities.

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.
