Molecular structure of DNA. Nucleotide. Nitrogenous base, phosphate.

An elaboration on how to use Newton's second law when dealing with multiple forces, forces in two dimensions, and diagonal forces.

Outcomes:

• Determine which mutations are favored by the selection agents of predators and food variety and which mutations are neutral.
• Describe which traits change the survivability of an organism in different environments.
• Experiment with environments which produce a stable population of bunnies, a population that dies out, and a population that takes over the world.
• Track genes through multiple generations.
• Compare how dominant and recessive genes get passed onto offspring.

Newton's second law of motion is F = ma, or force is equal to mass times acceleration. Learn how to use the formula to calculate acceleration.

Meiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells.

How homologous chromosomes separate into two sets. Prophase I, metaphase I, anaphase I, and telophase I.

Skeletons support and protect our bodies. Bugs have exoskeletons outside their bodies, while humans have endoskeletons inside. Our bones are in axial (skull, ribcage, spine) and appendicular (arms, legs) groups. Bone marrow makes blood cells; more specifically, red marrow makes blood and yellow marrow stores fat. 

Micturition (peeing) starts with urine flowing from the kidneys to the bladder via ureters. The bladder expands using transitional epithelium. Urine exits through the urethra, controlled by internal and external urethral sphincters. Ureters prevent backflow, thereby reducing infection risk
