O meiosis, fertilization, cleavage, gastrulation, neurulation, organogenesis, growth O gamete formation, organogenesis, neurulation, gastrulation, growth O mitosis, fertilization, cleavage, gastrulation, neurulation, organogenesis, growth O zygote formation, gastrulation, growth, organogenesis, neurulation, cleavage gamete formation, cleavage, growth, organogenesis, neurulation, fertilization

In one paragraph, using your own words, compare and contrast the processes of mitosis (asexual reproduction) and meiosis (sexual reproduction). Be sure to include proper spelling, grammar, and punctuation.

Select ALL of the following that occur during spermiogenesis: Microtubules form a flagellum The nucleus condenses O Proteolytic (digestive) enzymes are bundled in an acrosomal cap Excess cytoplasm is shed

Drag each label to identify wish pahse of meiosis it describes

In asexual reproduction only ______  ______________is involved, and the offspring are genetically _____________________to the parent. – In Unchanging environments In sexual reproduction _______ _________________are involved, and the offspring are genetically ___________________from the parent. – Changing environments Evolution is _____________  _____________over time in a ________________________. Different organisms have different genes. How is it that so many organisms seem perfectly suited to their environment? ___________  _____   ___________________. After a genetic __________or mutation in an organism, It survives, reproduces, and passes along its genes. Beneficial ______________ develop at random. The environment “___________” beneficial adaptations. Adaptations are an inherited characteristic.

What is a dauer larva ? It's a larva from a special variant of C. elegans that was first identified in samples from soil in Germany It is a larva that shows accelerated development in highly nutritious environments Dauer is just the technical term for "hermaphrodite" - so dauer larva means hermaphrodite adult It's a larva that arrests development in a low metabolic and enduring stage, caused by harsh environmental conditions. The larva will remain in the dauer stage until the conditions improve, at which point they'll resume development.

Which of the following is NOT true while comparing internal to external fertilization. In external fertilization, zygotic DNA replication starts after the fusion of gamete pronuclei; in internal fertilization, the first zygotic DNA synthesis happens before pronuclei fusion. B Capacitation is only observed in internal fertilization. In both internal and external fertilization, the cortical granule reaction is required for the slow block to polyspermy. In external fertilization, intracellular calcium release is stimulated prior to gametes fusion; in internal fertilization, it happens after gametes fusion. In both internal and external fertilization, there is a slow and a fast block to polyspermy.

Explain whether or not genetic variation exists from the parent to offspring organisms during asexual reproduction, AND why? Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent.
