These are some ways how scientists and engineers develop, use and refine models.
1. Imagine. They have to know what exactly trying to model. They have to imagine and brainstorm what are the things to be considered.
2. Reason. Next, they need to answer the questions brought from their brainstorming. They need to be able to reason out.
3. Calculate and Predict. Once they know it, that's the time they can start modelling and calculate - and predict.
Answer:
The amount of oxygen in the atmosphere would decrease.
Explanation:
If a massive toxic spill kills off half the population of photosynthetic plankton in the ocean. That would mean that only half of the original population of plankton will remain. Photosynthetic plankton consumes carbon dioxide from the atmosphere during photosynthesis to produce energy and releases oxygen.
The mass of vascularized connective tissue that temporarily forms during wound healing is called the granulation tissue.
Granulation tissue refers to the reddish connective tissue that forms around the surface of the wound during wound healing. It is associated with the formation of the new blood vessels renedering it a red color and delivers the nutrients to the tissue. It is primarily composed of a tissue matrix consisting of different types of cells which are associated with various functions like the formation of the matrix, protect against infection and the formation of the blood vessels which is called the vascularization. Fibroblasts are present in the extracellular matrix of the granulation tissue.
