Answer:
Mendel is known as the father of genetics. He explained the law of segregation by the monohybrid cross. The monohybrid cross involves the cross of a single trait at a time.
Law of segregation explains that at the time of formation of gametes, the allele pairs get separated from the pairs of trait. The concept of dominance was also explained. The traits that express itself even in the heterozygous condition is known as dominant trait (T). The trait that can not express itself is known as recessive trait (t).
For example:
Parents TT × tt. (Laws of segregation)
Gamete T t
F1 generation Tt.
Selfing of F1 generation
Tt × Tt
Offspring : TT (tall) , Tt (tall) , Tt (tall) , tt (dwarf).
The phenotypic ratio is tall : dwarf (3 : 1)

Answer:
False.
Explanation:
This phrase was described by Darwin in "The Descent of Man." Darwin, in his work, considered the superiority of man over woman as an adaptation. Even if we agree that it has at some tribal time contributed to the sexual division of labor, the struggle for gender equality today is proof that evolutionary explanations are not always sufficient, and that they should consider the cultural aspect more what sociobiology has done.
Men did not achieve superiority because of an evolutionary process, but through a cultural process that oppressed and weakened women for centuries. For this reason, the excerpt shown in the question is false. The main distinction in the intellectual powers of both sexes is shown through the capabilities of each individual, whether male or female.
<span>The Galapagos Islands are geographically isolated due to the Ocean that surrounds the islands themselves. The finches can't fly far enough to make it past the vast ocean to other mainland so they are stuck on the island and must adapt to what the island provides for food in varying areas.</span>
Answer:
Ia tidak mempunyai badan fizikal.
Penjelasan:
Jisim udara tidak diukur oleh keseimbangan tuas atau keseimbangan berat yang lain kerana mustahil untuk mengukur jisim udara. Hanya dua sifat udara yang dapat diukur seperti kadar aliran dan tekanan. Imbangan tuas mengukur berat bahan-bahan yang mempunyai badan fizikal sehingga sebab itu jisim udara tidak dapat diukur kerana tidak mempunyai badan fizikal. Udara mempunyai jisim tetapi tidak mempunyai badan fizikal sehingga mustahil untuk mengukur beratnya.
