- absorbs and blocks some of the harmful UV rays
- keeps oxygen and other gassed inside the atmosphere
- helps maintain the planet’s temperature to support life
Darwin went to the continents of Africa and South America, wherein both of them have a tropical grassland/Savanna biome. The grasslands in these continents gave him a chance to notice that species do vary globally. He observed the similarities between the different large, flightless birds species–rheas, ostriches, and emu.
Answer:
The way in which we produce our offspring, gametic meiosis, is very different than how bacteria and Bacillus cereus reproduce. In fact it is much simpler. The male doesn't have to buy the female anything, there is no commitment between bacteria, and it's just plain simple. Well, to start off there is no male or female in bacteria, and do not even need a partner to reproduce!
Often Bacillus cereus undergoes reproduction by the means of asexual reproduction (offspring are produced from a single parent; no this does not marital status), more specifically binary fission. Binary fission is the asexual reproduction method used by all prokaryotes, it occurs when a single parent cell undergoes mitosis and produces two equally sized daughter cells. Both daughter cells produced have the potential to grow to the size of the parent cell. The down side of binary fission is that both daughter cells are genetically identical.

This question is incomplete. However, let's understand some terms
Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.
The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.
