I would say C but In the integumentary system there are four main tissue types, those are Epithelial, Connective, Nervous and Muscular tissue
Answer:
The instructions for making proteins are coded in the (cytoplasm / <u>DNA</u> / endoplasmic reticulum / nucleus) of a cell. In a eukaryotic cell, these instructions are located in the (cytoplasm / DNA / endoplasmic reticulum / <u>nucleus</u>).
Explanation:
The genetic code is contained in DNA, or deoxyribonucleic acid. This is usually the same among most organisms, save some RNA viruses. But in eukaryotes, the DNA is in the nucleus, whereas in prokaryotes the DNA is in the "nucleoid region", or a twisted up section near the middle of the cell.
Answer:
The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells. The first man to witness a live cell under a microscope was Anton van Leeuwenhoek, who in 1674 described the algae Spirogyra. Van Leeuwenhoek probably also saw bacteria.
Explanation:
DNA:GCTAGCAG
RNA:CGAUCGUC therefore, C is the correct answer.
