Answer:
Some common insulators include wood, plastic, glass, porcelain and Styrofoam
Explanation:
With multiple lines on a graph you can compare different sets of data easier
Answer:
Polar
Explanation:
Polar is a concept which explains the formation of a particular molecule as a result of a separation of electric charges. In such molecule formed, there is a negatively charged end and a positively charged end. The difference in their electronegativity is what determines the strength of the bind formed in the molecule.
Electrically charges object can be used to attract molecules that are polar. This is because, when polar molecules are placed in an electric field, the positive charged end tends to align with the negative plate while the negatively charged end tends to align with the positive end.
Examples of polar molecules are water, hydrogen sulphide, ethanol, and some others.
Most of the gastric ulcers are caused by bacteria.
A sore when forms on the oesophageal, stomach, or small intestine lining. When stomach acid affects the lining of the digestive tract, ulcers develop. It is referred into three distinct ulcers-
- An ulcer on the lining of the stomach or the first section of small intestine is referred to as a peptic ulcer.
- A gastric ulcer is referred to as such if it develops in stomach.
- Duodenal ulcers are those that occur in the duodenum.
The causative agents of ulcer-
- The majority of ulcers are brought on by an infection with the bacteria or germ <em>H. pylori</em>. The mucus that covers the lining of your stomach and the first portion of your small intestine is damaged by this bacteria (the duodenum)
- Another major reason are NSAIDs (non-steroidal anti-inflammatory drugs). These include over-the-counter painkillers and antipyretics such aspirin, ibuprofen, and naproxen
- Lifestyle factors such as stress and alcohol consumption
The answer to the most causative factor for gastric ulcer is d) bacteria.

Answer:
1. 20 units
2. 4 units
Explanation:
In an ecosystem, energy is transferred from one organism occupying a trophic level to another as they feed on one another. The amount of energy that is being transferred as the chain progresses is called ECOLOGICAL EFFICIENCY. According to this question, the ecological efficiency at each trophic level of the ecosystem is 20%. This means that about 20% of energy units will be transferred to the next trophic level.
If the green plants of the ecosystem capture 100 units of energy, the amount of energy that will be available to support herbivores (plant eaters) is: 20% × 100units i.e. 20/100 × 100 = 20 units.
Also, the amount of energy that will be available to support carnivores subsequently will be 20% of 20 units i.e. 20/100 × 20 = 4 units.
