I believe it's RNA. But double check that please.
The correct answer is letter c. traps heat.
The Earth's Atmosphere deals with the sunlight it absorbs in the day, absorbing it and spreading it, which heats up the planet, but at night, the sunlight absorbed weakens and the Earth cools up, but due to the greenhouse effect, it traps certain amounts of heat, which results to hotness of the weather. Greenhouse Effect doubles the heat, because it traps heat when heat tries to leave our atmosphere.
Answer:
A very acidic pH level is 1, and a very basic pH level is 13.
I'm not sure I understand about your ratios, whether they are the choices or just numbers.
Explanation:
On the pH scale, the more you go to the left, the more acidic the solution is. Numbers below 7 are considered acidic, and the lowest number is the most acidic. The more you move to the right, the more basic or alkaline the solution is. Numbers above 7 are considered basic. So the higher the number of that side of the scale, the more basic stuff is. 7 is considered neutral.
Hope this helps you!! Feel free to leave any questions in the comments :)
Hello!! I think your best answer would be D - Tetrad because consists of four chromatids. It is made up of two (pair) of homologous chromosomes that have already replicated into a pair of sister chromatids. I hope this answers your question. Have a great day!! :)
