If the pennies were pre-1982 then 9 US pennies are very close to 1 ounce (9.145 pennies = 1 ounce). If the pennies are after 1982 then 11 US pennies are very close to one ounce (11.34 pennies = 1 ounce).
6 dollars equal how many pennies? I can answer that. You see, 1 dollar equals to 100 pennies. That means that 6 dollars = 600 pennies. I hope you understand me.
Certain algae is unicellular and microscopic. Multicellular algae can be microscopic, but often are not. Seaweed is an example of algae that is a single multicellular organism and not microscopic.
When Algae runs out of the proper nutrition it needs such as phosphates and other minerals it dies. Algae then dies and starts to decay during the decaying process Algae uses oxygen which is also why fish die from lack of oxygen. So to answer this question yes Algae does decay and consume oxygen.
Algae do not necessarily have to float on top of the water. Some species of algae have adapted to their environment and actually live underwater so they do not have the risk of drying out. The surface algae though floats because it is not very dense (tightly packed) so it has air bubbles that allows it to float.
you kill the algae
Algaecide can usually get rid of algae. Unless the water in circulating there is no way to prevent algae buildup on wet surfaces.
fresh water
My mother has a small decorative pond and has a few various pennies and some nickles that children have thrown in. It is relatively clear of algae. The copper from the penny we have been told kills the algae. I would assume that a small piece of copper pipe would have the same effect.
To prevent algae from growing and to kill bacteria
By keeping it in a sealed container with the same temp at all times.
This is because green algae are always in water. So, they don't need to prevent water loss because they're always in contact with water.
Bottled water is basically 100% pure water(H2O). The bottle is air-tight to prevent contamination, this means that it is only filled with nothing but water and not algae. The presence of algae growing in it means that it's contaminated and it is generally unsafe to drink.
Yes. Chlorine is used to prevent the growth of algae. Some pools use salt.
BioGuard makes a product called "Banish" that kills all types of algae in swimming pools. Pressure washing with bleach water will get rid of algae on surfaces. Removing dead leaves from ponds will prevent growth as it causes organic debris on which detrimental algae thrives. Filtering the pond will also help greatly.
you are probably referring to algae. It is slimy and green and grows in water when exposed to lots of sunlight. This is why it is smart to add aquatic plants to your pond, which shade the water and prevent growth of algae.
No but it can be problem sometimes. There are algaecides that can be added to the water when filling a bed that will prevent it from forming and growing.
