Human activities that increase the amount of CO2 in the atmosphere include, the burning of coal/ other fossil fuels, cement production, deforestation, and other landscape changes.
Climate change causes the oceans to absorb more heat, resulting in an increase in sea surface temperatures and rising sea levels. This change in ocean temperatures and currents brought about by climate change can lead to alterations in climate around the world.
Climate changes affects crop growth, meat production, fisheries, and other fundamental aspects of our food supply. This is because if our climate is constantly changing our Earth will no longer be able to sustain the adequate necessities of food production.
Climate change cause health issues. Change in climate can cause existing health problems to intensify and new health issues to emerge. Climate change can influence air pollution, allergies, disease carried by vectors, food and waterborne diseases, food security, mental health and stress-related disorders, floods, temperature extremes, and wildfires. All of these factors can have negative effects on ones health.
To reduce the negative effects of climate change we can speak up about climate change, use renewable energy, weatherize, invest in energy-efficient appliances, reduce water waste, make less food waste, etc.
Answer:700 nm corresponded to light in the red range and 450 nm corresponded to light in the blue range.
Explanation:The wavelengths of the visible spectrum are usually between 400 nm and 700 nmn with the the rays of red light having a longer wavelength, and blue light rays having shorter wavelengths. The red light has a low frequency of about 405–480 THz and , blue light has a higher frequency in the range of 620–680 THz. This is due to the inverse relationship between wavelength and frequency which also occurs betwwn wavelength and energy of light rays with the red light having less photon energy of about 1.65–2.00 eV and the blue light with high energy photons of about 2.64–2.75 eV.
Red light can be employed in the photosynthesis in plants as it helps in formation of flowers and the production of fruits. Blue light also is important in the production of chlorophyll and can cause a healthy and strong stem and leaves in excess exposure.
Answer:
Carbon
Explanation:
The non metal in the same group as Pb is carbon or C .
I hope this helps you.
The best way to predict the isomer of the given molecular information is to count the number of possible peaks present in spectra and compare it with the possible number of peaks given by each isomer. (Remember: This is not the final way to elucidate structure, but it is applicable in this question).
Explanation:
The number of peaks present in spectra are 8. Now, we will calculate the number of peaks given by each isomer.
ISOMER A: 1 peak for two equivalent methyl C attached to N
1 peak for carbonyl C
1 peak for methylene C
1 peak for methyl C
and 4 peaks for benzene C's as 2 carbons at ortho position and meta position to any of the two functional groups are equivalent hence give single signal.
So, 1+1+1+1+4 = 8
And it (Isomer A red) is the correct answer, because other two isomers give more than 8 peaks as they have no equivalent carbons in benzene ring.
