What do you think will happen to the convection currents in the mantle if the interior of Earth eventually cool down?

Answers

Answer 1
As the magma cools and solidifies, the convection currents will stop and the Earth will become geologically dead.

Explanation:
Convection currents within the Earth's mantle are caused by hot material rising upwards, cooling, then dropping back toward the core. These currents are thought to be the driving force for tectonic plate activity in the crust. The moving magma in the mantle carries the plates floating on top of it.
As a result of convection, the Earth's crust is constantly being created and destroyed. The average age of the Earth's surface is 2-2.5 billion years, which is about half the theoretical age of the Earth!
If the interior of the Earth were to cool enough for convection currents to stop, then the motion of the plates would cease, and the Earth would become geologically dead. Astronomers believe that this happened to Mars long ago.
Many of Mars's surface features suggest that at one point Mars had tectonic plate activity. Today, however, Mars is a static world and the only geologic activity is in the form of erosion and bombardment from space.

Which region in the table is most likely experiencing desert formation? Explain.

Hint: Think about where the population is increasing the most quickly. ​

Answers

Answer:

Africa is most likely experiencing desert formation because it's annual growth rate is the highest of them all.

In the given scenario, Africa is most likely experiencing desert formation as it is having highest growth rate percent.

What is growth rate?

The average annual rate of change in population size for a given country, territory, or geographic area over a given time period.

As the given regions are undergoing very rapid desert formation, Africa would go through this process, as it is having highest growth rate.

How can an abiotic factor like temperature impact the population size of an ecosystem

Answers

Answer/Explanation:

Abiotic factors are non-living factors such as temperature, light, water, humidity, acidity, etc.

They strongly impact the ability of organisms to grow and successfully reproduce, and therefore affect the diversity of organisms in any given area.

If the temperature, light, and water availability (for example) are optimal, then species of plants will be able to grow successfully. This increases their populatuion size. Not only that, but it also provides a greater food supply for the animals that eat the plants, so their population will also grow.

Using public transportation and turning lights off when leaving a room are both non-technological ways of improving air quality. Therefore, (A) and (C) are correct.

What is air quality?

An air quality index is a tool that is used by government agencies to communicate with the general public about the current level of air pollution as well as the level of air pollution that is expected to occur in the near future.

The Clean Air Act regulates a number of key air pollutants, including ground-level ozone, particle pollution, carbon monoxide, and sulfur dioxide. The AQI is determined based on these four pollutants. The Environmental Protection Agency (EPA) has developed national air quality standards to safeguard the general population from each of these contaminants.

We can improve the quality of the air by:

Try to cut down on the amount of times you drive your vehicle.Use of fireplaces and wood stoves should be cut back or eliminated entirely.Avoid burning anything, including leaves, rubbish, or other objects, on fire.Try to avoid using lawn and garden equipment that is powered by gas.

Fill in the Punnett square below to visualize the offspring of a cystic fibrosis carrier and a person who doesn't have cystic fibrosis and isn't a carrier. Use F to denote the normal allele and f to denote the mutated CFR allele. What percentage of their children are likely to have cystic fibrosis? What percentage of their children are likely to be carriers of cystic fibrosis?

Answers

Answer:

50% of their children are likely to be carriers of cystic fibrosis

Explanation:

Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF". The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.
