Answer:
The right answer is B. The offspring are genetically distinct ... by sexual reproduction.
Explanation:
Sexual reproduction, as opposed to asexual reproduction, indicates that the propagation of a species involves male and female gametes. It is the main method of reproduction of multicellular organisms.
In the first stage of sexual reproduction, meiosis, the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During fertilization ("fertilization"), haploid gametes come together to form a diploid zygote and restore the initial number of chromosomes (2n).
Human exploitation of fragile ecosystems can lead to the droughts and arid conditions characteristic of desertification. Effects include land degradation, soil erosion and sterility, and a loss of biodiversity, with huge economic costs for nations where deserts are growing.
