A. Fine Focus.
B. Nucleus, Cytoplasm, and membrane
C. 30 Micrometer.
Erythrocytes are well known to have no nucleus but in fact, they lack most organelles such as the Golgi apparatus endoplasmic reticulum and mitochondria. Hair consists of two parts the root and the hair shaft. The root is the part of the living hair located in the middle layer of the skin the dermis.
Epidermal root cells in some plants produce root hairs and tubular growths that increase the surface area of the root. Unlike other cells in the body, red blood cells do not have a nucleus. This habit dates back to when mammals began to evolve. Other vertebrates such as fish reptiles, and birds have erythrocytes that contain dormant nuclei. To allow red blood cells to carry an increased load of oxygen cells evolved to function without a nucleus and other associated organelles.

The correct sequence of events that occur during the cell growth and reproductive process or cell cycle would involve that cytokinesis which involves splitting or separating of the cytoplasmic media connecting the cells together to produce 2 new cells that have the same genetic content, occurs after Mitosis.
The correct response would be C. Cytokinesis follows mitosis.
The following answer to the equation is landslides
Answer:
False
Explanation:
In eukaryotes apart from RNA polymerase, the transcription of genes requires many different proteins called transcription factors. These transcription factors are important to initiate and regulate transcription.
There are two types of transcription factors regulatory and basal transcription factors. Basal transcription factors regulate transcription by binding to a gene promoter and regulatory transcription factor regulates transcription by binding to some regulatory sequences for example enhancers and silencers.
Therefore only basal transcription factor binds to the promoter for regulating transcription. Therefore the statement is false.
Radioactive decay is measured in half-lives.
