<u>Fibroblasts are cells located in the dermis,</u> responsible for the formation and remodeling of tissue. They synthesize fibers and maintains the extracellular matrix of the tissue of animals. So, t<u>he extracellular matrix is a structurally complex entity that surrounds and supports the cells found in tissues</u>.
A cell junction a structure that exists within the tissues of animals and they consist of protein complexes that provide contact between cells or between a cell and the extracellular matrix. So if the cells do not appear flattened and do not attach to the extracellular matrix, then there is a problem with the components of cell junctions, which are mostly proteins as it was said before. And since proteins are coded by genetic information stored in DNA, then if there is a mutation in any of those genes, the fibroblast will fail to attach because the protein of the cell junction will be abnormal.
The answer is different magnification lenses. Leeuwenhoek use a microscope with different magnification lenses which enabled him to see bacteria. <span>His microscope was able to achieve 50-300x magnification, which enabled him to see a variety of bacteria.</span>
The 8 characterstics of life are as follows: 1. Made of cells 2. Adapt and Respond to environment 3. Homeostasis or Internal Balance 4. Based on genetic code- DNA or RNA 5. Evolution- all organisms evolve over time 6. Consume energy 7. All organisms reproduce 8. All organisms grow and develop
A thick grouping of nerves that run down the back of the embryo
Explanation
The dorsal nerve cord is special embryonic characteristic of the ganglia. It is a hollow dorsal cord that is composed of a section of the exfoliated coagulant that forms a hollow tube unlike solid abdominal tubes in other animal species. It is located in the vertebrae of vertebrates.
