The correct response is this: NATURAL SELECTION FAVORED THE EVOLUTION OF LARGER BRAINS, THIS SUGGESTS THAT THE BENEFITS OF LARGE BRAIN OUTWEIGHS THE COSTS.
In fossils record, the shift from Australopithecus to homo is characterized by larger body and brain sizes and all through subsequent evolution, brain size has to continue to get bigger. The possession of large brain make man to be much more advanced in thinking than all other animals.

How do fungi break down leaves, fruit, and other organic material into simple molecules?
morpeh [17]
Fungi are eukaryotic and saprophytic microorganisms that grow on dead and decaying matter. These organisms release digestive enzymes that break down  leaves, fruit and other organic material into simple molecules. These can grow on wood, clothes, food, fruits, leather shoes, etc by breaking down complex organic matter into simpler forms with the help of extracellular digestive enzymes such as cellulases, proteases, phosphatases, etc.

5. The F2 generation of a cross between a parental tall and a parental short pea plant is 298 tall plants and 102 short plants.
Vadim26 [7]

Answer:

The answer is XX.

Explanation:

Let us say that X is the dominant gene and x is the recessive gene for the height of the pea plants. Pea plants need to be homozygous or heterozygous  to have the short phenotype which means it needs to have the genotype xx or Xx.

The F2 offspring has a ratio of 74,5% tall plants and 25,5% short plants. For these results, the stem height pea plant needs to be homozygous which is an XX genotype for the tall pea plant.

I hope this answer helps.
