General Science Questions

Electronic Flash differs from the consumable bulb flash in important aspects. Instead of creating light by burning up in an atmosphere containing oxygen, a consumable material (each bulb being used therefore only once), it produces a brilliant incandescent by discharging a current for a brief instant through a rarified gas, usually xenon. The gas glows every time the discharge is made through it but it is not consumed, so that many thousands of flashes are obtainable from a single tube, which helps to offset the much higher cost of the initial apparatus.

Plants are photosynthetic autotrophs, which means that they are able to produce their own food through the process called photosynthesis.

In photosynthesis, plants use light, water, and carbon dioxide to create glucose, which they convert to cellulose and use to make new cells.

Hence, that is why, Plants are called photosynthetic autotrophs.

Developing a habit of wearing your lifejacket or PFD at all times also reduces the chance that you will drown should you find yourself in the water unexpectedly.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms activities.

Chloroplasts are organelles in plant and bacteria cells that contain the chlorophyll is responsible for photosynthesis.

A protein that acts as a hormone is INSULIN.

Insulin is a peptide hormone produced by beta cells of the pancreatic islets; it is considered to be the main anabolic hormone of the body.  Insulin helps keeps your blood sugar level from getting too high or too low.  

The ability of two or more substances to combine to form other substances is called Reactivity.

Water reabsorption by the renal tubules is harmonally controlled and it is a osmosis mechanism.
