Gnoma [55]
<span>As there are many kinds of deserts, some hot, some cold even arid deserts are the classic hot deserts, but there are also cold and coastal deserts where temperatures do not get so high. The element common to all of these types of deserts, however, is their lack of rainfall. In that sense the rainfall is a characteristic that determines if it's a desert.</span>

Bacteria: a member of a large group of unicellular microorganisms which have cell walls but lack organelles and an organized nucleus, including some which can cause disease.
Fungi/fungus: any of a group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.

Altruistic behavior a. is that which benefits others while causing a disadvantage to the individual. b. is not a beneficial evol
Maksim231197 [3]

The correct answer is A. Is that which benefits others while causing a disadvantage to the individual.

Explanation:

In biology, altruistic behavior occurs as one organism actions benefit other organisms either because these actions increase the reproductive fitness or the chances an organism survives and prevails over time. Additionally, altruistic behavior implies there is a disadvantage for the organisms acting in the benefit of others. For example, wolves or similar animals take food to those that did not participate in hunting, which means they help other wolves to survive on their own cost as this means less food for those that hunted. According to this, altruistic behavior "is that which benefits others while causing a disadvantage to the individual".
