Explain how human activity can affect the carbon cycle.
Answers
Answer:Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.
Explanation:
Answer:
Burning of Fossil Fuels= When oil or coal is burned, carbon is released into the atmosphere at a faster rate than it is removed. As a result, the concentration of carbon dioxide in the atmosphere increases.
Carbon Sequestration= When plants remove carbon dioxide from the air and store it, the process is called carbon sequestration. Agricultural and forestry methods can affect how much carbon dioxide is removed from the atmosphere and stored by the plants.
Deforestation is the permanent removal of trees from forests. Permanent removal of the trees means new trees will not be replanted.
Human activity can affect the carbon cycle by capturing carbon dioxide and storing it underground rather than permitting it to be released into the atmosphere. This process is called geologic sequestration.
Explanation:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life. It describes the movement of carbon as it is recycled and reused throughout the biosphere, as well as long-term processes of carbon sequestration to and release from carbon sinks.

Answer:
vestigial structures
Explanation:
A "vestigial structure" or "vestigial organ" are defined as the organs that no longer have any function in the organisms' body but had an important role in past.
Pelvis and femur are thigh bones in humans which helps them in walking but in whale's pelvis and femur are considered as vestigial structures.
The pelvis and femur in whales, are the inherited structure from ancestors and shows evidence for evolution on the basis of natural selection.
Hence, the correct answer is vestigial structures.

Prisims separate _____ light, such as that form the sun, by wavelength.
Answers
Answer:
Prisims separate WHITE light, such as that form the sun, by wavelength.
Final answer:
Prisms disperse white light into a spectrum of colors through a process called dispersion, where light of different wavelengths is refracted by different amounts due to varying refractive indices. Instruments like spectrometers use prisms to separate and analyze these different wavelengths of light.
Explanation:
Prisms separate white light, such as that from the sun, by wavelength through a process called dispersion. Dispersion occurs because different frequencies of light have different refractive indices for a given material. When white light enters a prism—a piece of glass in the shape of a triangle with refracting surfaces—the path of the light is refracted (bent). However, not all colors are bent by the same amount; the bending of the beam depends on the wavelength of the light as well as the properties of the prism. Consequently, different wavelengths (or colors of light) are bent by different amounts and follow slightly different paths. The violet light is bent more than the red light, and, as such, when white light leaves the prism and is focused on a screen, the different colors line up side by side like a rainbow. This separation of colors is a key aspect of spectroscopy.
Additionally, instruments such as spectrometers are used to disperse light and form a spectrum for further analysis. In these devices, light enters through a small hole or narrow slit, is collimated by a lens into a parallel beam of rays, then passes through the prism. Different wavelengths leave the prism in different directions, and a second lens focuses these different images onto a detecting device, such as a CCD. This allows for careful examination of the spectrum created by the dispersion of light.
An 80-meter sequoia tree is in the forest. What is most likely the age of the tree?
A.1 year
B.12 years
C.100 years
D.1,200 years
Answers
Answer:
The correct answer is option D. "1,200 years".
Explanation:
The giant sequoia (Sequoiadendron giganteum) are the most massive trees in the world, and the tallest is one sequoia called "General Sherman" with a height of 83.8 m. "General Sherman" is estimated to be 2,000 years old, and is estimated that a sequoia tree can live up to 3,500 years. Therefore, an 80-meter sequoia tree in the forest most likely will have more than 1,000 years.

The correct answer is B.) The moon orbits Earth.
Trust me, I got it right :)
The trait is that the planets have a circular orbit around the Sun. The Option B.
What is a common trait of all solar system models?In all solar system models, a common trait is that the planets have a circular orbit around the Sun. This means that the planets follow a path around the Sun that is roughly circular in shape.
This trait is based on the understanding that the gravitational pull of the Sun keeps the planets in orbit, and the circular orbit is the result of the balance between the gravitational force and the forward motion of the planets. While the orbits of some planets can deviate slightly from perfect circles, the overall pattern of circular orbits is a fundamental characteristic shared by all planets in the solar system.

Using the data from the graph, explain the relationship between the population of snowshoe hares and the population of the lynx. Explain what the graph's lines mean about the relationship.
Answers
As you already know, lynx are predators of hares and a balance between the populations of these two animals is necessary, so that the populations have a stable growth.
As you can see in the chart above, when the lynx population is very low, the hare population is high. This is because, as there are few lynxes, predation is low and hares are able to maintain their birth rate higher than the mortality rate. However, there are many hares available for lynx to feed on, which allows the lynx's birth rate to also be higher than the mortality rate, which causes the lynx population to grow.
Also according to the graph, you can see that as the lynx population grows, the hare population decreases. This is because the greater number of lynx causes predatorism to increase and hares are hunted by lynx in greater quantities. This causes the mortality rate of hares to be higher than the birth rate, which decreases its population. On the other hand, the abundance of food allows the lynx population to grow to some extent. This is because, as you can see in the graph, when the hares population is very small, the lynx does not have enough food, which causes an increase in the mortality rate, also decreasing the lynx population.
When the lynx population is low, predatorism is lower, which allows hares to reproduce by increasing their population, which will result in an increase in the lynx population.
The graph shows how the population of snowshoe hares and lynx are related over time. When hare population is high, lynx population increases, and when hare population decreases, lynx population decreases.
Explanation:The graph shows the relationship between the population of snowshoe hares and the population of lynx over a period of time. The x-axis represents time, while the y-axis represents the population size. The lines on the graph indicate the trends in the population sizes of both species. When the snowshoe hare population is high, the lynx population tends to increase, as lynx feed primarily on hares. However, when the hare population decreases, the lynx population also decreases due to a lack of food.

Giardia is a microscopic single celled prokaryotic organism that causes giardiasis. Giardiasis is an intestinal Infection in humans and dogs which is caused by giardia. It is an eukaryotic organism that have nucleus and nuclear membrane but it lacks other ORGANELLES that are present in Eukaryotic organisms. It causes diarrhoea in humans and woman's can get infected from dogs.
Answer:
B. It has a nucleus
Explanation:
All living organisms were classified into a large group called DOMAIN. These organisms were classified into two domains viz EUKARYA and PROKARYA depending on whether or not they possess a nucleus. Organisms in the Eukarya domain called Eukaryotes possess a membrane-bound nucleus that houses their genetic material (DNA) while organisms in Prokarya domain called prokaryotes do not possess a membrane bound nucleus.
Based on this, Giardia organism that is described to be an eukaryotic organism that causes illness in cats, dogs and humans is distinguished from any prokaryote by its possession of a membrane-bound nucleus in the cytoplasm of its cell. Any organism referred to as EUKARYOTIC must possess a NUCLEUS.

What chemical in the igniting of the match causes the acid to be produced?
Answers
Answer:
When the match is struck a portion of the red phosphorus on the striking surface is converted into white phosphorus, which then ignites. The heat from this ignites the potassium chlorate, making the match head flame up.
Explanation:
Final answer:
The ignition of a match causes a combustion reaction involving P4S3 and KClO3, generating heat, light, and byproducts like carbon dioxide and water vapor.
Explanation:
The chemical responsible for the ignition of a match and subsequent acid production is a compound of phosphorus and sulfur, specifically P4S3 (tetraphosphorus trisulfide). When a strike-anywhere match is rubbed against a rough surface, friction generates enough heat to initiate a combustion reaction. The KClO3 (potassium chlorate) in the match head also plays a crucial role by providing the oxygen necessary for the phosphorus-sulfur compound to ignite.
Upon ignition, a series of reactions occur that result in the combustion of the match, using cellulose in the match and oxygen from the air to produce energy in the form of heat and light. The chemical reaction between these components forms carbon dioxide and water vapor as byproducts.
