Prey selection within a specie of western garter snakes across a wide range in California is a genetically based behavioral variation.
Answer:
<h2>Meiosis I</h2>
Explanation:
1. Meiosis (meiosis I and meiosis II) produce four daughter cells from a single cell, each daughter cell contains half the number of chromosomes as compared to parental cell.
2. Meiosis have two cycles , i) meiosis I and ii) meiosis II.
3. In meiosis I, chromosomes first go replication and become double. It is the first step (meiosis I) that generates genetic diversity. During prophase I of meiosis I, homologous chromosomes pair and form synapses, a special step of meiosis.
4. There is crossing over in meiosis I which produce genetic diversity.
5. The four cells produced from a single cell become genetically different due to crossing occur which occur in meiosis I.
Amount of O2 inhaled;
500 x 20.94% = 104.7mL
Amount of O2 exhaled;
500 x 16.37% = 81.85mL
Difference = 104.7 - 81.85 = 22.85mL
