Answer:
scientist has brought together all the research on the subject and found that, from bees to birds to wolves, many animals have an ability to process and represent numbers arguably a form of counting.
Explanation: What's more, the new study suggests that this mathematical prowess helps animals stay alive in a brutal world. Such a finding extends our knowledge of animal cognition, a field that has grown exponentially in recent years.
Answer:
The natural selection on polygenic traits affects selection.
Explanation:
The natural selection process allows changes in frequencies of alleles in a character that is determined by single gene. The polygenic characteristics are disproportionately affected by natural selection as natural selection affect the phenotype distribution.
This occurs in three ways that are disruptive selection, stabilizing and directional selection.
The macromolecule would probably be the carbohydrate.
