Answer:
biotic and abiotic interactions
on gradpoint
Explanation:
Heat from the Earth's core and radiation from the Sun is transferred to the surface of the Earth by conduction. Contact of the atmosphere with these warm surfaces transfers thermal energy, which then heats up the rest of the air through convection.
The atmosphere is also slightly heated by absorption of electromagnetic radiation from the Sun. The warm land and water radiates infrared, some of which is absorbed by the atmosphere, adding to its thermal energy. The remaining heat on the surface is sent out into space in the form of infrared radiation.
Answer:
b. The beetle population has few predators in the new habitat.
Explanation:
Based on the scenario being described within the question it can be said that the best explanation for this is that there are few or no predators to kill them off. This is due to the fact that a predator to a certain species kills off a certain portion of the population for food which in term maintains the population of the preyed upon species at an average level, and thus prevents them from exponentially growing out of control like what is happening with the beetles.
Answer:
Check the explanation
Explanation:
Average weight before selection =2.5 kg
Average weight after selection = 5.5 kg
Average weight in the next generation =3.5kg
= 
R= Mean weight in the next generation - mean weight before selection
= 3.5-2.5 = 1.0
S= Mean weight after selection -mean weight before selection
= 5.5 - 2.5 = 3.0
= = 
= 0.33
Answer:
If the DNA wasn't duplicated, one of the daughter cells wouldn't have DNA and die.
Explanation:
The cell would split into a cell that had DNA and would survive and a cell that wouldn't survive. The one that doesn't have DNA wouldn't be able to go through cellular functions. Why? The DNA needed to direct functions wouldn't be present.
