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).
Answer:
The correct answer is D. involves proteins in plasma membranes.
Explanation:
Animal cells have several types of proteins embedded in their cell membrane. These proteins play an important role in the transport of molecules, cell recognition, and cell communication.
Recognition proteins are a type of glycoproteins present in the plasma membrane that allow one cell of the body to recognize the other body cells by making contact with recognition proteins of other cells. Receptors proteins allow cell-cell communication by receiving extracellular proteins.
These proteins are important for proper growth and development of the cell. Therefore the correct answer is D. involves proteins in plasma membranes.
