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.
The answer to this question is the "coal-burning power or the power plants". Hence, the Airborne mercury has received special attention because it is a widespread and persistent neurotoxin. TA neurotoxin is a substance that damages the brain and the nervous systems. Minute doses can cause nerve damage and other impairments, especially in the young children and the developing fetuses. The majority of the airborne mercury is released by POWER PLANTS or coal-burning plants. Many people are affected and get sick that is why when there is a proposed new power plant project, most people object and opposed.
Answer:
lactose and maltose
Explanation:
only sucrose is a non reducing sugar
Answer:
<em>1. They effect crop productivity</em>
As weeds start to grow in the area where the crops were destined to grow, the production of the crops gets lowered.
<em>2. They deplete the crops from nutrition</em>
The weeds will compete with the crop plants for resources such as minerals from the soil.
<em>3. They will deplete water resources</em>
The weeds will compete with the crop plants for water.
<em>4. Sun-light will be depleted</em>
The weeds will complete with the crop plants for sun light.
<em>5. The crop quality will be affected</em>
As the crop plants will be in competition with the weeds, hence their quality will be affected.
6. <em>They can reduce the biodiversity of crop plants.</em>
Answer: The overgrowth in deer population led to a food shortage.
Explanation:
Since the eradication of the wolves, the deer had no predator to keep their total population in check. Due to the vast amount of deer the food in the area was being eaten at a faster rate. Most of the deer died do to their environment not being capable of feeding that many deer.
