because this process repeats every time a nerve impulse is passed down the axon‚ and is important as it allows the action potential to be passed along the axon. Examples of biological cycles at a cellular level include the cell cycle‚ mitosis and meiosis. Most eukaryotic cells follow this process‚ which includes a growth stage‚ mitosis or nuclear division‚ and cytokinesis. Throughout interphase‚ the cell undergoes growth and metabolic activities. Interphase can be further broken down into G1 (where

A Chromosome Study Lab An examination of the chromosomes of a cell under high magnification can give much information about an organism. Figure 1 shows the chromosomes of a somatic cell as they might appear in an organism if enlarged many times their natural size. A somatic cell is any cell making up the organism except for reproductive cells. In this investigation‚ it is expected that you: a. learn what a chromosome Karyotype is. b. prepare a Karyotype of chromosomes according to the instructions

3. In some pea plant crosses‚ the plants are self-pollinated. Refer back to Concept 13.1 (pp. 248–249) and explain whether self-pollination is considered asexual or sexual reproduction. 3. Self-pollination is sexual reproduction because meiosis is involved in forming gametes‚ which unite during fertilization. As a result‚ the offspring in self-pollination are genetically different from the parent. (As mentioned in the footnote on p. 263‚ we have simplified the explanation in referring

Anatomy of the Male Reproductive System Scrotum The scrotum is a sac-like organ made of skin and muscles that houses the testes. It is located inferior to the penis in the pubic region. The scrotum is made up of 2 side-by-side pouches with a testis located in each pouch. The smooth muscles that make up the scrotum allow it to regulate the distance between the testes and the rest of the body. When the testes become too warm to support spermatogenesis‚ the scrotum relaxes to move the testes away
