How do humans cycle carbon from the biosphere to the atmosphere? (1 point)
by respiration
by driving cars that use gasoline for fuel
by eating plants
by planting vegetable crops
Answers
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy.
Explanation:
Humans cycle carbon from the biosphere to the atmosphere by respiration, driving cars that use gasoline for fuel, eating plant parts, planting vegetable crops. So, all these processes are playing a major role in the carbon cycling by Humans.
What is Carbon Cycle?
The movement of carbon from the reservoir to reservoir is known as the carbon cycle. The carbon Cycle occurs through the atmosphere, oceans, and through living and dead organisms.
Humans during respiration inhale Oxygen and exhale Carbon-dioxide, vehicles also emit smoke consisting mainly of carbon, plants' bodies also contain a proportion of carbon.
Therefore, Humans cycle carbon from the biosphere to the atmosphere by respiration, driving cars that use gasoline for fuel, eating plant parts, planting vegetable crops. So, all these processes are playing a major role in the carbon cycling by Humans.

Answers
Answer:
Cells of the immune system are able to respond to the presence of invading organisms because they recognize the antibodies present in the invading pathogen
Explanation:
The mechanisms of human immunity can be grouped into two broad categories: the innate or nonspecific immune system, which provides a first and general defense against any element recognized as foreign, and the acquired or specific immune system that recognizes specific threatening agents and generates a response directed against those elements. When foreign substances enter our body (bacteria, viruses, parasites, proteins from other animal or plant species, cells from other organisms - including those of human origin - and a long etcetera, all of which are given the common name of antigens) and are brought into contact with cells that are members of the immune system, the foreign element or antigen is first captured by certain types of cells that are collectively known as antigen-presenting cells. These cells would correspond to the intelligence service and their mission is to take the antigens, introduce them inside, process them and present the antigens on their surface in a fragmentary way to other cells of the immune system. This results in the activation of lymphocytes that specifically recognize the antigen and ends in the development of mechanisms that mediate the physiological function of the response, that is, the elimination of the antigen. Thus, the immune response can be functionally divided into three phases: the antigen recognition phase, the activation phase of the response, and the effector phase.

Density independent factors refer to any influences on a population's birth or death rates, regardless of the population density. Whereas, Density dependent factors affect a population through increasing or decreasing birth and death rates.
if the checkpoint finds an error, what are some actions the cell can take to ensure the error does not get replicated?
Answers
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2.
Explanation:
um i think this is correct. hope this helps and have a nice day
-KindnessMatters-
The cell cycle is the intricate process of replication of genetic material and producing the daughter cells. The cell cycle is regulated by several mechanisms, one of which is checkpoints.
Checkpoints are the sites where the cells are checked for errors and inaccuracy in the cell.
The cell takes action to ensure errors are not replicated as:
The G1 checkpoint in the cell cycle is the primary checkpoint, which decided whether the cell should divide or not divide. It checks for size, DNA damage, and nutrients. The cell cycle will halt if there will be any errors. The G2 checkpoint is involved in the overall smoothening of the cell cycle. If any damage is observed after the other checkpoints, the cell cycle will pause in the G2 phase, halting the replication of errored genetic material.The M checkpoint corresponds to accurate attachment of the sister chromatids and the cycle will be in pause if the proper attachment is not done.
Thus, there are several checkpoints to check the errors in the DNA, and if any error persists, the cell cycle will be halted.

Is the relationship between Riftia pachyptila and the chemosynthetic bacteria an example of symbiosis?
Answers
Answer: YES. The relationship between Riftia pachyptila and the chemosynthetic bacteria is an example of SYMBIOSIS.
Explanation:
Nutrition is the series of process by which living organisms obtain food substances and use them to provide energy and materials for their growth and maintenance. There are 2 major modes of nutrition which includes:
--> Heterotrophic nutrition: this is the type of nutrition in which the organism depends on manufactured food for survival. Heterotrophic organisms may be SYMBIOTIC which means that it can live together with another organism as they both benefit from each other.
--> Autotrophic nutrition is the type of nutrition in which an organism has the ability to manufacture its own food. This can be achieved through the process of CHEMOSYNTHESIS. In this process, they synthesis organic compounds with the use of energy from inorganic compounds such as carbondioxide. An example is the chemosynthetic bacteria found in the gut of Riftia pachyptila.
Riftia pachyptila is an aquatic invertebrate that is seen at the seafloor near hydrothermal vents ( high temperature area). They do not have digestive system that will enable them make use of the inorganic materials (carbondioxide, sulphide) found in their environment. But within their paired coelomic cavities are chemosynthetic bacteria.
The relationship between Riftia pachyptila and the chemosynthetic bacteria is an example of SYMBIOSIS because the chemosynthetic bacteria depends of the Riftia pachyptila for the necessary inorganic compounds for its own metabolic reactions and excretion of by products while Riftia pachyptila depend on the bacteria for byproducts from its metabolic reaction which is needed for its growth.
YES, the connection between Riftia pachyptila and therefore the chemosynthetic bacteria is an example of SYMBIOSIS.
Nutrition-Nutrition is the series of processes by which living organisms obtain food substances and use them to supply energy and materials for growth and maintenance.
There are 2 major modes of nutrition which includes:Heterotrophic nutrition is the sort of nutrition during which the organism depends on manufactured food for survival.Autotrophic nutrition is the sort of nutrition during which an organism has the power to manufacture its own food. this will be achieved through the method of CHEMOSYNTHESIS.Riftia pachyptila is an aquatic invertebrate that's seen at the seafloor near hydrothermal vents ( heat area).
They do not have gastrointestinal system which will enable them make use of the inorganic materials (carbondioxide, sulphide) found in their environment. But within their paired coelomic cavities are chemosynthetic bacteria.
The relationship between Riftia pachyptila and therefore the chemosynthetic bacteria, chemosynthetic bacteria depends on the Riftia pachyptila for the required inorganic compounds.
For its own metabolic reactions and excretion of by-products Riftia pachyptila depends upon the bacteria for byproducts from its metabolic reaction which is required for its growth.
Therefore, Yes, the relationship between Riftia pachyptila and the chemosynthetic bacteria are an example of symbiosis.

Hey y'all I need help with this bio question: what are the pros and cons of different skin tones in different parts of the world?
Answers
It basically all boils down to Vitamin D! We need this essential vitamin to help our body build hormones and regulate calcium. Our bodies make Vitamin D when we are exposed to the UV rays found in sunlight. But as we all know, too much sunlight isn’t good because these UV rays can harm us. Melanin (the chemical that our bodies produce to darken skin tone and hair color) provides protection from UV rays by absorbing them. However, this means that the more melanin that is produced by someone’s body results in less absorption of UV rays and a decrease in Vitamin D production. But for someone living around the equator or in the tropics that doesn’t matter because there’s lots of sun all the time. So for humans living in these areas where there’s lots of sunlight year round, it’s beneficial to have darker skin to protect from the harm of UV rays. People living in these areas still get plenty of Vitamin D though because of that year round sunshine.
Now what about those who’s skin has less melanin, such as those found in the higher latitudes? Well with less sunlight year round, their bodies had to adapt to be able to get enough Vitamin D. So less melanin is produced by the body in order to absorb the lesser amounts of UV rays to make Vitamin D. Lighter skin is, therefore, more beneficial the farther away you go from the tropics.
So essentially:
Pro of Darker Skin tones
-Protection from harmful UV rays
Con of Darker Skin tones
-Less absorption of UV rays and less production of Vitamin D
Pro of Lighter Skin tones
-Greater absorption of UV rays and more Vitamin D production
Con of Lighter Skin tones
-Less protection from harmful UV rays (resulting in sunburns and, in extreme cases, skin cancer)
This is of course the biology answer. The social impacts of different skin tones is a whole different story that you can ask in the history section.

What conditions are necessary for rocks to melt? ( I’ll give a Brainliast) please answer
Answers
Answer:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
Answer:
Flux melting occurs when water or carbon dioxide is added to rock. These compounds cause the rock to melt at lower temperatures. This creates magma in places where it originally maintained a solid structure. Much like heat transfer, flux melting also occurs around subduction zones.
