What is cancer?
Cancer is a cell desease that makes cells outgrow the space they're in, creating tumours. It's a desease that makes cell growth abnormal.
Where does cancer start, how does a cell become cancerous?
Cancer starts in the cells nucleus, more specifically in the chromosomes (logical since it's a desease related to a cells growth/reproduction cycle). There are three known ways that a cell can become a cancerous.
1 - It will suffer a mutation with a DNA "coding" error.
2 - Translocation fails, putting sets of genes in the wrong places.
3 - Self-copying error, either an excess or a dearth of replicas.
How to create a cancer-resistant cell?
So, the simplest way would be studying the options above, and see which one of those is the most common case (tracing the "origins" of cancer can be hard) and then try to modify cells to prevent it from failing.
The easiest way of doing so, will be studying the genetic fails and doing genetic modifications to the genes functionality. I personally do not think that's an option now, because playing around with cells isn't as safe as it looks. We would have to advance both in "cancer-knowledge" and technology to find a solution.

Explanation:
It is true that the wings of the bee move very fast. The wings are smaller than their body and it is believed to be difficult for the wings to lift the whole body of the bee.
Sometimes, bees carry nectar and pollen with itself which again increases their weight. It has been found that the wings do not move up and down rather moves to and from. Since air is denser, it tries to push the air downwards and lift itself upwards.
Periodic inventory systems are used most commonly by companies that sell low-priced, high-volume merchandise.
<h3>What do you mean by Periodic inventory systems?</h3>
Periodic inventory systems may be defined as a strategy of inventory valuation in which a material count of inventory is executed at specific intervals.
Periodic inventory systems regularly updated their inventory balance to analyze their expenditure, profit, and loss.
Therefore, periodic inventory systems are used most commonly by companies that sell low-priced, high-volume merchandise.

At the end of the winter they are most numerous in fresh water. they will cover surface of aquatic plants or poles and wooden borders of ponds. If you like to study them you can scrape the brown growth with a flat piece of plastic. you can also use a sponge. for the free living (plankton) species fine mesh plankton net is very useful.
