Answer:
Average atomic mass = 21.38 amu.
Explanation:
Given data:
Mass of first isotope = 21 amu
Abundance of first isotope = 62%
Mass of second isotope = 22 amu
Abundance of second isotope = 38%
Average atomic mass = ?
Solution:
Average atomic mass = (abundance of 1st isotope × its atomic mass) +(abundance of 2nd isotope × its atomic mass) / 100
Average atomic mass = (62×21)+(38×22) /100
Average atomic mass = 1302 +836 / 100
Average atomic mass = 2138 / 100
Average atomic mass = 21.38 amu.
Explanation:
Its stomach was filled eith 30 plastic bags, and many smaller pieces of plastic. ... The whale was emaciated, and scientists believe that the plastic had gathered in such an amount in its stomach that it had created a plug, stopping the digestive process.
The cause of death appears to be starvation, though that's under investigation. Many of the stranded whales in 2019 have been malnourished, said David Weller, a research wildlife biologist with NOAA's Southwest Fisheries Science Center in La Jolla, California.
Answer:
The answer is G
Explanation:
This is because cells cannot just appear out of thin air all cells have to have come from pre-existing cells.
I filled out a few boxes for you to start you off. I also gave you a direct research sources for some animals that will take you to the necessary information.
This is what I have so far as examples for you. Again, I said I wouldn't do all of your work for you, however, I will help you through your research and graph.
The correct answer is "The oil removed by this structure can be used to power ships."
Oil rigs are positive, effective and direct methods of recovering crude oil. It is a large construction on or in water with facilities to drill wells, to extract and process oil and natural gas, and to temporarily store product until it can be brought to shore for clearing and retailing.
