Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. ... These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.

Answer:
Cuando el entorno donde se encuentra la semilla cuenta con las condiciones idóneas se produce el inicio de la vida de la nueva planta. El proceso comienza con la ruptura del envoltorio de la semilla y la aparición de la raíz. De manera sencilla podemos dividir este hecho en varias etapas que son clave para comprender el proceso de crecimiento de las plantas. Así es cómo crecen las plantas.
Explanation:
Answer:
Dendrochronologists have shown that tree-ring data produce a remarkably accurate history of droughts and other climate changes.
Explanation:
The underlying patterns of wide or narrow rings record the year-to-year fluctuations in the growth of trees. The patterns, therefore, often contain a weather history at the location the tree grew, in addition to its age. In dry environments, such as the Middle East or U.S. Southwest, tree rings typically record wet or dry years, and in cooler areas (high latitudes or high elevation), the ring widths are often a proxy for temperature.
The outcome of this scenario is gene flow between the two com populations (Option b). It may lead to the introduction of the genetically modified allele into the natural population.
<h3>Gene flow and cross-pollination</h3>
Gene flow refers to the interchange of genes (alleles) between different populations as a consequence of mating and/or migration.
Gene flow leads to the mixture of different alleles in the populations, which will be selected in each environment in order to shape allele and genotypic frequencies over time.
In this case, maize is an allogamous plant, which means that cross-pollination and gene flow will occur between different maize (corn) populations.

Then maybe we would die because sometimes we people eat fish and also the ecosystem of the ocean like the animals that eat fish such as sharks.
