Explain how carbon cycles through the ecosystem in which you live.

PLEAASE HELP :((

Answers

Answer:Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

The graph below shows the averaged sunspots from 1610 to 2007. The graph shows sunspot number on the y axis and years 1600, 1650, 1700, 1750, 1800, 1850, 1900, 1950, and 2000 on the x axis. The graph rises and falls in a cyclic order in gaps of approximately 10 years. The number of sunspots observed in 1610 was 40, in 1650 it was 5, in 1700 it was 10, in 1750 it was 90 and the number of sunspots in 1800 was 50. The number of sunspots observed in 1850 was 130 and the number of sunspots in 1900 was 10. The number of sunspots observed in 1950 was 150 and the number of sunspots observed in 2000 was 30. Based on the graph, which of these conclusions is correct? Some of the previously warm regions became colder from 1650 to 1700. Some of the previously cold regions became warmer from 1600 to 1700. Some of the previously warm regions became warmer from 1610 to 1700. Some of the previously cold regions became colder from 1900 to 1950.

Answers

Answer: Some of the previously warm regions became colder from 1650 to 1700

Explanation: I got it right on the test

According to the graph, the number of sunspots decreased from 1650 to 1700. That means the correct option is A.

What is a sunspot?

The areas of the sun where the magnetic field of the sun is 2500 times more than the Earth. In these areas, the magnetic field is more than anywhere else on the surface of the sun.

Near the area of a sunspot, there is a small amount of energy output from the sun. UV rays from the sun also increase at a high sunspot activity. This increase in UV radiation causes dramatic effects on the atmosphere of the Earth.

The more number sunspots are observed, the more energy will be delivered to the earth. This increase in the energy delivered to the earth would result in an increase in the overall global temperature.

According to the graph, the number of sunspots observed decreased from 40 to 5 and increased slightly from 5 to 10 from 1610 to 1700. So, the statement says that some of the warm regions would become colder from 1650 to 1700.

Therefore, the correct option is A.

A. High daytime temperatures allow them to grow as large as the food supply will allow.


B. Cold nighttime temperatures limit their size, because large ectotherms need a long time to warm up in the sun.


C. High daytime temperatures limit their size, because large endotherms would overheat on very hot days.


D. Cold nighttime temperatures limit their size, because large endotherms would lose too much of their body heat.

Answers

Answer:

A. High daytime temperatures allow them to grow as large as the food supply will allow.

Explanation:

Snakes and lizards are cold-blooded animals. This type of animal cannot maintain a constant body temperature and depends on the temperature of the environment to keep warm and keep its organs and metabolism working.

Room temperature is so important to these animals that they even determine the size of their bodies. For these animals, high temperatures allow them to have their metabolism accelerated, so they can grow as much as the availability of food allows. On the other hand, if there is not enough food, or very cold temperatures, they will need to be smaller in size, as the metabolism will be slow.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?

Answers

Answer:

This question is incomplete, the complete question is as follows:

- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.

What percentage of offspring are expected to be chestnut?

The answer is 0%

Explanation:

This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.

According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;

BB - B only

bb - b only

Using these gametes in a punnet square, the following proportion of offsprings will be produced:

Bb, Bb, Bb, Bb

All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0%  of offspring are expected to be chestnut.

Why is the classification species not considered a group

Answers

Answer:

All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups.

There are five kingdoms: • Animals • Plants • Fungus • Protist • Bacteria Scientists classify animals together because they have similar characteristics such as they eat other living things and have many cells. As you can see from the chart, kingdoms are divided into groups called phyla.

The classification of species is not considered a group because each species is a separate type of organism. The correct option is D.

What are groups and species?

Group is the level of taxonomy in which the organism is present, which has someone's character. Like in the insect group, all insects are present.

Species are the largest level of the taxonomy of the organism. Species are animals or plants or individuals that have the same characteristics and those that can mate with each other and form fertile offspring.

Groups contain numerous species. Like in insects, the insects contain numerous insects that are very different from each other. Like, bees and beetles are very different from each other.

Thus, the correct option is D. Each species is a separate type of organism.

Read the following passage from the Biology Department at University of California, Berkeley.

Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.

Which of the following best describes how the population has evolved?
The population has not evolved because there was no change in allele frequencies.
The population has not evolved because it has grown.
The population has evolved because it has grown.
The population has evolved because there was a change in allele frequencies.

Answer:

the last one sorry if i'm wrong

Explanation:

According to the passage from the Biology Department at University of California, Berkeley.Northern elephant seals have reduced genetic variation because hunting by humans reduced their population size to as few as 20 individuals at the end of the 19th century. Their population has since rebounded to over 30,000, but their genes still carry the marks of this near extinction: they have much less genetic variation than a population of southern elephant seals that was not hunted as intensely.

The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.

What is population?

The term population reffered to the total number of people living in a particular given area.The population of an organism can't survive if it exceeds it's carrying capacity.

The causes that affect population growth animals that if there are more plants than usual in area, populations of animals that eat that plant may increase.

If animal population increases the population that eat that animal might also increase.

The effects of animals population can be dangerous and when population exceed the carrying capacity of their environment, animal suffer of malnutrition and disease.

When predictors became scarce due to over population, the weekar species of animal start or die in other ways .

The accurate description of the growth of a natural animal population is limited by environmental factors.

Therefore,The best option that describes is" the population has not evolved because there was no change in allele frequencies.Thus, option B is correct.
