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.
Radiation can damage DNA. This could result in a change in the proteins which make up the plant's physical structure.
<span>For example, a plant might have a gene for purple pigment which makes its flowers purple. Radiation might change the DNA sequence so that the directions for making the purple pigment tell it to stop prematurely, and the result might be white flowers rather than purple flowers.</span>
On day one the levels of oestrogen and progesterone are low, having dropped quickly at the end of the last cycle. Low oestrogen level causes FSH release from the pituitary gland.
The rekation between inslin and glucagon is they both secrete a harmones in respone to blood sugar levels,but in opposite fashion.
