How does diploidy help to preserve genetic variation? see concept 23.4 (page 498)?
mario62 [17]
Monoploid organisms reproduce asexually since they need to transmit all of their genetic material to their offspring. Diploid organisms, have 2 copies of their genetic material that differ slightly in their genes. Since the progeny gets half of the DNA from each parent, we have that new combinations can emerge; for example, if the mother is AA for some allele and the father aa, their offspring will be Aa, a new genotype. This might have different implications (for example, the recessive gene for thalassemia also provides resistance to malaria). Finally, during meiosis, there is also an event called crossover that increases the genetic variation of the offspring.

jasenka [17]

Answer:

O sal tem uma grande capacidade de absorver água do ambiente.

Explanation:

A passagem de oxigênio pelas guelras de um peixe é um exemplo de difusão porque a difusão ocorre quando a concentração de uma substância é maior em uma região e menor em outra região, de modo que as partículas se movem da região superior para a região inferior. A glicose entra na célula por meio do processo de transporte passivo facilitado porque passa por uma membrana semipermeável por uma proteína específica. O transporte iônico nas células nervosas é o exemplo do transporte ativo porque se move pelo uso da energia contra o gradiente.

O sal tem uma forte capacidade de absorver água do seu entorno, então quando a alface temperada com sal, o sal absorve a água presente no interior da alface, portanto a retirada da água é a retirada da água é a causa do murchamento.
