Answer: for me the best option is D.
Explanation: lets explain this.
Cellular respiration begins with a process that divides the glucose within the cells making it readily available as a source of energy. This process can occur without oxygen (anaerobic respiration) or in the presence of oxygen (aerobic respiration). Anaerobic respiration generates more excess waste (lactate) than aerobic . Besides, high levels of lactate build within the muscle cells. Excess lactate slows the cellular respiratory process and is experienced as a burning sensation in the muscles if exercise continues.
The steroids are produced by the Smooth endoplasmic reticulum.
The cells, which are involved in the secretion of the steroid molecules have an abundant number of the smooth endoplasmic reticulum, which is abbrevated as SER.
The cells present in the ovary and the testis have a large number of smooth endoplasmic reticulum. The abundant number of smoothe endoplasmic reticulum allow them to produce a large amount of steroid molecule to produce the steroid hormones estrogen and testosterone.
Hence, in this case, the ovarian cells would have a large number of SER.
Water and carbon are major components of all life.Prokaryotic and eukaryotic are the two major categories of cells making up life on earth.
In eukaryotes, <em>replication takes place in the nucleus</em> as prokaryotes do not have a true nucleus and <em>replication takes place in the cytoplasm</em>. The nucleus of the eukaryotes is the location where genetic material (DNA) is found; in prokaryotes, the genetic material is condensed in the cytoplasm called the nucleoid. There are multiple replication forks or <em>multiple origins of replication </em>in eukaryotes in contrast to prokaryotes which only has <em>one origin of replication. </em>Lastly, replication in eukaryotes <em>occurs at multiple points along the chromosome; </em>in contrast with prokaryotes where it <em>occurs at just one point on the chromosome.</em>
