Answers

Answer: b. Interdependent.

  • Even if one of the components in an ecosystem is removed, the entire ecosystem gets disturbed and, it affects the other components as well.
  • So organisms in the same ecosystem are all interdependent.
The answer is B. interdependent.

Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation. true false User: The nuclear envelope disintegrates during _____.
metaphase
prophase
anaphase
telophase

Answers

Question 1. The statement that 'Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation' is true. Crossing over is the exchange of genetic material between homologous chromosomes that occurs during meiosis. As the result, the daughter cells are genetically different from mother cells. It is one of the ways to produce genetic variation. Question 2. The nuclear envelope disintegrates during prophase. This is the process that occurs at the beginning of mitosis. During prophase, the first phase of mitosis, the chromosomes condense and the nuclear envelope disintegrates. At the end of mitosis, the chromosomes will decondense and the nuclear envelope will re-form.
Prophase is the answer
