The steps of tissue repair in order from start to finish are 1, 3, 2, 4.
The method of tissue repair follows some steps below especially when the damaged tissue are in close apposition.
These steps in order from start to finish include:
- Bleeding into the cut: This is the homeostasis stage. As the wound bleeds, the aim of this stage is to stop the bleeding by activation of emergency repair system, the blood clotting system.
- Scab formation; macrophages become active: This is the inflammatory stage. Phagocytes such as the macrophages begin to remove the dry blood clot called scabs and cell debris.
- Formation of granulation tissue and fibroblastic phase of repair: This stage is called the proliferation stage. Granulation tissue which contains new capillary buds, phagocytes and fibroblasts, develops. Fibroblasts continues to secrete collagen fibres for the tissue restoration.
- Epithelial regeneration; fibrosis; remodeling phase: This is the maturation stage. Here, the granulation tissue is replaced by fibrous scar tissue and rearrangement of the collagen fibres occurs, increasing the strength of the wound.
Therefore, the steps of tissue repair in order from start to finish are 1, 3, 2, 4.

Answer:
The correct answer is Ovule
Explanation:
The evolution of the seed is a very important step of evolution in land plants. The evolution of the seed enable plants to grow away from the very moist environments. That is why gymnosperms soon became the dominant plants. Gymnosperms and angiosperms both have ovule whcih is after fertilization becomes seed. The ovule in the gymnosperm is naked and not enclosed in the fruit, whereas in the angiosperms seeds are enclosed in the fruits.
The medulla oblongata is the part of the brain stem that regulates the bodily processes that are automatically regulated such as respiration and blood pressure. During respiration process, the medulla oblongata functions by detecting the level of carbon dioxide and oxygen in the blood stream and sending necessary signals in form of nerve impulses to the heart muscles and diaphragm for necessary actions. This shows that the respiratory system and the circulatory system work together and that is the reason why heart rate and breathing rate are both controlled by medulla oblongata.
