How much of a 500g sample of potassium-42 is left after
37.2 hours if the half-life of potassium-42 is 12.4 hours.
Please solve its due tomorrow there’s also more-
Answer:
15.625 g of a 500 gram sample of potassium-42 with 12.4 hours of Half -life is left after 62 hours.
The half-life is the time after which half of the initial quantity of a radioactive substance is left .
Given here,
The half-life of K-42 = 12.4 hours
The initial quantity of K-42 = 500 gm
The final quantity after 62 hours = ?
The number of half cycle
\bold { = 62\times \dfrac 1{12.4} = 5,}=62×

Thus the number of half life cycles in 62 hours is 5,
After 1 half life \bold {= \dfrac {500}{2} = 250}=

how does the use of fossil fuels affect the cyrosphere
Answer:
It has absorbed about 25% of the carbon dioxide generated by fossil fuel burning and other human activity and has slowed warming by also absorbing heat. Global warming causes melting of ice on land such as glaciers, and ice sheets in Antarctica and Greenland, adding water to the ocean, and thus raising sea level.

How did the peppered moth change in response to the pollution in its environment?.
Answer:
The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism.
Explanation:
The peppered moth's evolution is an example of how air pollution during the Industrial Revolution caused directional colour changes in the moth population.
What is evolution?The process of evolution is how organisms change over time in response to their environment.
Any net direction change or cumulative change in an organism's or population's features over many generations is considered evolution, or descent with modification.
The genesis and dissemination of alleles, variations, trait values, or character states are expressly mentioned.
The evolution of the peppered moth is an illustration of how moth population changes in directional colour were brought on by air pollution during the Industrial Revolution.
At that time, a manifestation of industrial melanism was the rise in the number of dark-colored moths.
Thus, this way, the peppered moth change in response to the pollution in its environment.

Think of what you have learned about the cell theory and stem cell research. How did the development of the cell theory lay the foundation for the current advancements in stem cell research?
Answer:
Why is it important to learn about stem cells and stem cell research?
Researchers hope stem cell studies can help to: Increase understanding of how diseases occur. By watching stem cells mature into cells in bones, heart muscle, nerves, and other organs and tissue, researchers may better understand how diseases and conditions develop.
How does stem cell research affect society?
Research with embryonic stem cells may lead to new, more effective treatments for serious human ailments and alleviate the suffering of thousands of people. Diseases such as juvenile diabetes, Parkinson's disease, heart failure and spinal cord injuries are examples.
For all living things to survive, stem cells are essential. As a result, stem cells might be necessary for the evolution of particular traits in animals, such as regeneration, multicellularity, and coloniality.
What is Stem cell theory?According to the stem cell theory of ageing, the inability of various stem cell types to continuously supply the tissues of the an organism by functional differentiated cells capable of preserving those tissues' original function leads to the ageing process.
In the body, stem cells have the capacity to differentiate into a wide variety of cell types. They act as the body's system for repairs. Adult stem cells and embryonic stem cells are the two primary categories of stem cells.
The evolution of particular traits in organisms, such as regeneration, multicellularity, and coloniality, may thus require stem cells.
Thus, for all living things to survive, stem cells are essential. As a result, stem cells might be necessary for the evolution of particular traits in animals, such as regeneration, multicellularity, and coloniality.

Mira analyzed oxygen and carbon dioxide in inhaled and exhaled air. she found that the percentages of both gases were different in each. what other gas would most likely also have different amounts in inhaled and exhaled air? ozone (o3) hydrogen (h2) water vapor (h2o) sulfur dioxide (so2)
Breathing is the process of inhaling oxygen and removing carbon dioxide. Just like oxygen and carbon dioxide, Water vapor also have different amounts in inhaled and exhaled air.
What is respiration?The process of inhaling oxygen and releasing carbon dioxide and releasing energy is called respiration.
The first step towards respiration is breathing, which is done by inhaling oxygen and exhaling carbon dioxide through nostrils.
The amount of different gases varies in environment.
During breathing amount of inhaled air contains different percentage of oxygen and carbon dioxide as compared to exhalation.
The reason for such variation includes the use oxygen from the inhaled air to release energy and give out carbon dioxide as a byproduct by the cell.
Water vapor is also inhaled and exhaled in different amounts just like oxygen and carbon dioxide.
Thus, the correct option is C.
