Answer:
Schleiden, Schwann, and Virchow are the 3 major contributors to the cell theory.
Answer:
Telophase I: 8 chromosomes composed of two sister chromatids
Crossing over refers to the mechanism of recombination, this process being characterized in that increases the genetic variation
Spermatogenesis refers to the mechanism of formation of male gametes (sperms), while oogenesis is the process of formation of female gametes (oocytes)
Explanation:
Telophase I is the final step in meiosis I. During telophase I, the nuclear membrane is formed around the decondensed set of chromosomes and the nucleoli reappear.
Spermatogenesis refers to the process by which haploid male germ cells (sperms) are generated within the seminiferous tubules in the testis, while oogenesis refers to the process of differentiation of the female egg cells (ova or oocytes) in the ovaries. Spermatogenesis is known to produce small and motile spermatic cells, while oogenesis is known to produce bigger non-motile oocytes.
D, all of the above. Your body sweats when it gets too hot to cool the body, and shivers when it gets too cold to heat the body. The nervous system is responsible for sensing everything in and around the body.
D: The cell is the basic unit of structure and organization in organisms. Explanation: cause I got the question right.
