HELP ME PLEASE! The global climate is changing, and this change is apparent across many of Earth’s subsystems. Multiple sources attribute the global warming of the past 50 years to human activity and influence. Activities such as deforestation and burning fossil fuels such as coal, oil, and natural gas release carbon dioxide (CO2), methane, and nitrous oxide into the atmosphere. These heat-trapping “greenhouse gases” have increased global temperatures and caused changes such as melting glaciers and powerful storms. These changes are happening because Earth's air, water, and land are all linked to its climate. How do you think greenhouse gas emissions and global climate will change during the next 50 years? If greenhouse gas emissions and global temperatures continue rising, what other changes might you expect to see throughout the world? Humans are working to reduce the amount of greenhouse gases released into the atmosphere, but are their current solutions going to make a big enough impact? In addition to reducing human dependence on fossil fuels, what other solutions could help combat greenhouse gas emissions and global warming?
Explanation:to control global warming we should control the green house gases which are the carbon dioxide formed by burning fossil fuels, methne formed by burning Agricultural fields, and also the nitrous oxide from nylon manufacturing.
So as a solution we should use technologies whichcan reduce smokes like by using solar and electric cars and recycling wastes instead of burning

As stated last unit, people are the ones at fault for destroying the earth, which was proven during the April 2020 quarantine. The earth was healing itself since it didn't have people to hurt it, which is sad when you think about it. I think we are on the right track with using more renewable energy sources, carpooling when possible, drive electric cars, etc. If nothing is done, then we could see possible extinction of species, due to the disruption of the food chain, melting of polar ice caps, etc.
But I believe that 50 years from now, the climate will be much worse than it is today. I think that global warming will reach a peak, most likely within the next century, and then start cooling down as people realize they need to start being more careful with their planet. I believe that because of the heat, the ice caps will start melting more and more, leading to the rising of sea levels and drastic flooding. People are trying to help save the planet, but it might not be enough. Solar power, electric cars, and making deforestation illegal all help, but we need to do more. We need to make solar power and electric cars more popular and wider spread. We also need to make growing back the destroyed forests a top priority. I believe that humans are trying, but we need to get more people on board to help.

Laboratory aprons are often required during lab activities. Your instructor will tell you whether it is mandatory or not. True False
Answer:
True
Explanation:
Before students can begin work in a laboratory, they would need proper orientation on the dos and don'ts in the laboratory. The orientation is important because the laboratory is a place where serious work is done and which houses chemicals that could be dangerous when not handled properly. The orientation is provided by an instructor who among other things explains to the students why an apron is important and should be worn at all times during laboratory activities.
The laboratory apron is important as it protects people in the laboratory against corrosive materials. It is also designed in a way that it can be easily pulled from the wearer when an accident occurs. After this orientation the students would not have to be reminded everyday by the instructor about the importance of laboratory aprons.
It is true that laboratory aprons are often required during lab activities. Your instructor will tell you whether it is mandatory or not.
When performing lab work, aprons are frequently needed to protect the wearer's clothing from possible spills, splashes, or chemical exposures.
The particular requirements for donning a lab apron, however, could differ based on the lab, institution, or type of experiment being carried out.
In order to determine whether or not a laboratory apron is required for a given lab activity, the instructor or lab supervisor is the reliable source.
To ensure safety and compliance with the unique procedures of the laboratory, it is crucial to adhere to the directions and guidelines given by the teacher.
Thus, the given statement is true.

Answer:
1. the cause of magnetic pole reversals
2. the year the next magnetic reversal will take place
4. the exact location of the next earthquake along the California coast
Explanation:
Due to magnetic striping patterns, the magnetic pole of earth go in reverse direction. When the magma comes out from the ocean floor so it spreads on the ocean floor making new bands. So these new bands that spreads the ocean floor make a new floor which change the polarity of the ocean floor in opposite direction. Due to this magnetic striping, the magnetic reversal will take place in which polarity of the earth crust reverses.

How might you explain the discrepancy between the normal length of prolactin (199 amino acids) and the length of the polypeptide synthesized in your experiment (227 amino acids)
The best way to explain the discrepancy between the normal length of prolactin (199 amino acids) and the length of the polypeptide synthesized in the experiment (227 amino acids) is that in the absence of Signal Recognition Particle (SRP) and the Endoplasmic Reticulum membrane,a prolactin precursor molecule is therefore synthesized.
Prolactin also plays a role in the stimulation of the proliferation of oligodendrocyte precursor cells.
Relating to all, The Signal Recognition Particle plays a crucial role in mediating the transport of secretory and membrane protein to the Endoplasmic Reticulum or plasma membrane.
This can occur both in the prokaryotic or eukaryotic cell.
