Answer:
The pumping method of sodium-potassium pushes sodium and potassium ions against elevated concentration levels. It transfers two potassium ions into the cell where the levels of potassium are high, and pumps three sodium ions into the extracellular fluid and out of the cell.
Explanation:
ATP's hydrolysis is an active transport mechanism by the passage of sodium and potassium ions across the cell membrane to provide the required energy.

The effect of carbon dioxide on the atmospheric temperature is BEST shown by graph
Answer: definitely C will help you
Explanation:
Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.
What is the main reason of emission of carbon?According to the information given in the question, we can state that global temperatures tend to increase as carbon emissions increase due to green house effect.
According to the information in the question, the increase in carbon emissions is one of the main factors responsible for the increase in global temperatures.
This can be proven by observing the graph, where it is possible to see that there was a significant increase in global temperatures, as carbon emissions increased.
These carbon emissions are the result of the increase in human activities and industrial processes, which promote the degradation of the atmospheric layers and allow an intense increase in global temperature.
Therefore, Due to green house effect carbon emission increases rapidly day by day due to which the temperature of earth has been increasing with respect to time.We can clearly observe that the graph C shows the exact condition. Thus, C is the correct option.

The zygote is said to be Choose... , because it is able to develop into any kind of cell in the body. Adult stem cells are referred to as Choose... , because they can differentiate usually only into the cells of the tissues where they are found, whereas embryonic stem cells are Choose... because they can develop into any of the body’s cell types, although they cannot form the tissues surrounding the embryo.
Answer:
The correct answer is -
1. totipotent
2 multipotent
3. pluripotent
Explanation:
The cells that are able to develop or differentiate a different kind of cells in the body of the individual are known as totipotent cells and this ability is known as totipotency. An example of such cells is found in the zygote.
Multipotent on the other hand are the cells that are able to develop into a specific kind of cell of tissues these cells are present and the example of this type of cell is adult stem cells. Whereas Embryonic stem cells are Pluripotent cells that are characterized as the cells that develop into any type of cell of the body of an organism.

D. archaea
The kingdom that contains single-celled organisms that live in extreme environments is archaea. The correct option is D.
What are single-celled organisms?A single cell makes up a unicellular creature, also referred to as a single-celled organism, as opposed to a multicellular organism, which is made up of numerous cells. Similar to Eukarya, Archaea have RNA polymerases that are more complicated than those of bacteria.
Archaea do not have peptidoglycan in their cell walls, in contrast to bacteria. The membrane lipid bonding of archaea differs from that of bacteria and eukarya.

Reactant
Product
Activation energy
Bond
Endothermic
Exothermic
Rate
A chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires a minimum amount of energy.
A reactant is a starting substance in a chemical reaction, whereas products are formed at the end of the reaction.The rate of reaction is the velocity of the chemical reaction.Activation energy refers to the minimum amount of energy required to activate reactants and thus start a chemical reaction. The chemical reactions store/release energy by destroying/building chemical bonds between atoms/molecules.Exothermic reactions release energy when the bonds are formed; whereas endothermic reactions consume energy.In conclusion, a chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires energy. These reactions can be exothermic processes or endothermic processes.

The cell structure is formed according to their function.
Explanation:
Form and function are related to each other in human cells because the cells structure is formed according to its function. epithelial tissue are the group of cells that act as coverings of the body and controlling the movement of materials across their surface whereas muscle tissues are group of cells that are responsible for the movement of the body. Both tissues has different structure which allows it to perform different function.

Sometimes new ideas in science come from traditional methods people used in the past. What did researchers learn from terra preta? How is bio-char different from the traditional Amazonian method of creating terra preta?
Answer:
What did researchers learn from terra preta?... Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.
How is bio-char different from the traditional Amazonian method of creating terra preta? Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..
The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.
Terra preta is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Researchers have learned from terra preta that it contains a high level of carbon, along with nutrients such as nitrogen, phosphorus, and potassium.
What is terra preta soil?Terra preta, or "black earth," is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Scientists have studied terra preta to understand its unique properties and how it was created. Terra preta is a type of anthropogenic soil, which means that it was created by human activity rather than natural processes. It is believed that the indigenous people of the Amazon region created terra preta by adding biochar to soil along with other organic materials such as bones, shells, and manure.
Hence, researchers have learned from terra preta that it contains a high level of carbon along with nutrients such as nitrogen, phosphorus, and potassium.
