Answer: Lek Polygyny
Explanation:
Polygyny is a mating system inwhich one male is associated with multiple females. This mating system is found in a few birds and insects, but is most common in mammals. Polygyny is a strategy used by males to increase their reproductive fitness.
Lek polygyny is a system where male aggregate at a location and try to attract females for mating and the females leave after mating. It is believed that males attract more mate in this way than in isolation.
I would say burning a campfire would contribute most to climate change over the others.

Here's one I found interesting.
Can we ever beat photosynthesis?
-It’s one of the holy grails of energy; coming up with a material for capturing the energy of the sun which can beat the efficiency of photosynthesis. This is an incredibly challenging problem, to say the least. And it’s one that could have an outsize impact on our very way of life, leading to energy from water splitting and biomass from energy conversion.
Answer;
-23 in males
In humans, 23 in males is the only homologous chromosome pair that isn't the same.
Explanation;
-In humans, each cell normally contains 23 pairs of chromosomes, for a total of 46.
-Twenty-two of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.
-The 22 autosomes are numbered by size. The other two chromosomes, X and Y, are the sex chromosomes.
Choice 1 protons and neutrons, not electrons because they are in the outside circling it
