Darwin explained that evolution occur due to natural selection.
Answer:
The correct answer is - Chondroblasts; Fibroblasts
Explanation:
Mesenchymal progenitor cells will form chondrocytes combinedly called Chondroblasts that is responsible for the secretion of the rubbery matrix of cartilage.
Fibroblast on other hand produces fibers and ground substance. These ground substances and fibers make the matrix of the fibrous connective tissue.
Planet earth is the only known region of the universe to host life and so the basic criteria for life is based on observations made here. For an entity to be considered a living organism it must contain DNA or some other means of storing genetic information. The second criteria is that it must have some way of extracting nutrients from its surroundings. The organism must be able to respond to environmental stimulus and last but not least it must be able to reproduce.
Answer:
Restate the overall purpose of the experiment. (Why did you do this experiment? What did it teach you?)
2. What were the major findings? (summarize the data you collected)
3. Was the hyposthesis supported by the data? (state your hypothesis and explain how your data relates to your hypothesis)
4. How could this experiment be improved? (If you did this again what could you do differently?)
5. What could be studied next after this experiment? (What else could you test to help you better understand this topic
Explanation:
Answer:
NO. Mitosis involves one set of nuclear division and results in two nuclei that are exactly the same as the original. On the other hand, meiosis involves two sets of nuclear divisions.
Explanation:
Mitosis is a type of cell division normally occurring at the sites of growth and development of new tissues and also at sites of repair. It also occurs during asexual reproduction of organisms. Each mitotic cell division is a process that follows distinct phases.
Each mitotic division results in the formation of two daughter cells which are genetically identical to the parent cell, that is they have the same number and type of chromosomes as the parent cell.
During telophase, a nucleolus develops in the nucleus of each daughter cell. The cytoplasm divides in the process called cytokinesis. An invagination develops and finally splits the cell into two daughter cell each with its own nucleus and cytoplasm.
