Answer:
It helps organisms survive.
Explanation:
To elaborate, adaptive traits and behavior is learned because of a necessity to <em>survive</em>.
A good example might be vaccinations and your immune system. Your body needs exposure to a pathogen to learn what it does, then adapts to fight off the pathogen. It adapts to survive.
In a constantly changing world, if you can't adapt, you simply won't survive long enough.

Answer:
The correct answer is desert.
Explanation:
If an entomologist wants to look for a good example of an organism that prevents water loss, he must look for organisms in the desert.
A desert is one of the ecosystems that <u>receives less water</u>, the rainwater that falls is<u> less than 150 mm per year.
</u>
Despite the heat and lack of water, there is a wide variety of living beings that inhabit this type of ecosystem. But for that <u>they must save water</u>, and they do this through adaptations that they developed when they were living in this place.
They can have two types of adaptations: physical or behavioral adaptations.
In behavioral adaptations, desert animals simply avoid the sun to generate greater water retention. Depending on the species, <u>some choose to go out only during the night</u>, and others <u>prefer to be under the shadow of a cactus.
</u>
Some species also get the water they need through the food they eat, which prevents them from having to go in search of water.
One type of physical adaptation is the one that occurs in those animals who accumulate fatty tissue in their body which allows them to <u>stay fresh and thus prevent water from evaporating.</u>
Answer 1:
Suppose the tall fur length is determined by F gene and short fur length is determined by f, then according to Mendel law of segregation:
Parental generation (P)
Phenotype Tall fur length X Short fur length
Genotype FF ff
F₁ generation result
Ff, Ff, Ff, Ff (Heterogeneous tall fur length)
Self Cross Ff X Ff
F2 generation FF, Ff, Ff, ff.
Genotypic result:
FF (Homozygous tall fur)
Ff (Heterozygous tall fur)
ff (Homozygous shot fur length)
Phenotypic result:
3 = Tall fur length
1 = short fur length
Answer 2:
If the hamster have short fur, then possible genotype would be ff, as explained in answer 1.
