To reproduce, female elephants produce eggs and male elephants produce sperm. Offspring are produced by the fusion of an egg wit
h a sperm cell. Which statement is true about the offspring? A. The offspring are genetically identical to the parents because they are produced by sexual reproduction.
B. The offspring are genetically distinct from the parents because they are produced by sexual reproduction.
C. The offspring are genetically distinct from the parents because the egg and sperm are both diploid.
D. The offspring are genetically identical to the parents because the egg and sperm are both diploid.
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).
All organisms use a source of energy for their metabolic activities. Some organisms capture energy from the sun and convert it into chemical energy in food (photosynthesis); others use chemical energy in molecules they take in as food (cellular respiration)Explanation:
Earth’s axis passes through the North and South Poles. It takes Earth 24 hours to rotate once around its axis. Earth revolves once around the Sun in 365 days during a non-leap year.
