The observation, identification, description, experimental investigation, and theoretical explanation of phenomena is all part of science. Nothing is immune to the scientific process: from charm quarks that haven't existed naturally since the beginning of time to Pluto, recently demoted from planet to dwarf planet. Questions on knowledge about the material and physical aspects of our world are asked and answered here.

A cell membrane is found on both plant and animal cells it selectively chooses what substances may enter or leave the cell. Hence the term selectively permeable. For a more advanced explanation I recommend you research protein icebergs and the different types of transport a membrane can take part in...

People have only been to the moon. However, we can still see other  planets using telescopes, satellites and probes.
Well you have to set up a fraction ratio For example I want to convert 88 inches squared to mm not squared but just a length dimension88 inches x 1 mm/ 0.0393 inches = 2,239.185750636132 so inches ^2 divided by inches will leave you with inches and millimetres which is incorrect the correct way...
Mica is an interesting silicate mineral. The silicate series is:  quartz --> mica --> asbestos.   Quartz possesses three dimensional Si-O bonds which results in a  crystal that is strong in every direction. Consequently, quartz is  an exceptionally hard mineral.    Mica, on the...
Mainly salt water, excluding things like sea life.
It depends on how you eat it.   If you eat pure baking soda, you will be very unhappy--it tastes  really bad--but it won't hurt you because you couldn't eat enough  of it to throw your body's pH off. It will react with your  stomach's acid to neutralize it, which is why people take it for ...

When you give a plant sugar (through soil), its roots will absorb  it, and will be transported from the vascular tissues to the  leaves. There are 2 types of vascular tissues: Xylem (which  transports water and minerals), and Phloem (which transports  sugar). Although the type of sugar matters....
Let's look at human cells. If you didn't have cells you wouldn't exist. Your entire body, skeleton, muscles, organs, etc are comprised of cells. Inside those cells are thousands of water molecules (hence the reason your body is 70% water). The cells make it possible for everything in the human body...
First, the plant undergoes photosynthesis, as normal. Once the  glucose is produced, it is turned into starch through a process  called polymerization. This happens in the organelle known as the  amyloplast. Once the amyloplast has turned the glucose into starch,  it moves the starch to the...
No, well not much at least. The shape is very similar, but sometimes the eye socket shape changes depending on the breed. Some are more prominent then others.
This stands for European Union
Well, we know when things are heated or cooled to a certain point,  they change. So, it depends what chemicals you use. Like gasoline  in cars. The gasoline, along the way, is heated and it triggers  other points to get the car going.

If the two points are 'A' and 'B', you just told us that it's 170m . If 'A' and 'B' are not "the two points", then you've told us nothing about them. -------------------------- I trigonometry, we talk about "solving" a triangle. There are 6 pieces of information in triangle ABC: the 3 lengths AB,...
Radio waves have the lowest frequency.
Heat is transferred in three ways - radiation, conduction and  convection. Radiation is caused by the movement of heat waves.  Conduction is when heat is transferred by direct contact between  two items. Convection is when there are differences in temperature  and density causing the movement of...
Typically the roots will grow from the seeds.
Entirely possible. Usually a working enviroment that pays commission will let you work any hours you want, but will require you to be there a minimum amount of hours.
If the planet was exactly in between Mars and Jupiter, it would  take 3645.029 days. 
867 ÷ 75 = 11.56.
It is. Any number multiplied by 0 is 0.
Ya, cuz 1 time in Star Trek they had transparent aluminum. For some whales and junk and its totally based on actual events that will take place in the future probably.
They are not too far apart they bothered lie in the Middle East. They are about 3,000 miles apart. Hope this helped!
A single bond involves one electron from two atoms, bonding them  together with a total of two electrons.
The SI unit is the kilogram per meter (kg/m).
  Asteroids were formed with our solar system and have not changed since then they are therefore about 4,600,000,000 years old.
Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.Any incident ray traveling through the focal point on the way to the lens will refract through the lens and travel parallel...
Conductor means something that conducts or allows to pass through itself. for eg. plastic is a bad conductor of heat. now that means heat won't pass through plastic but it would certainly burn. But on the contrary, metal like aluminium would let heat pass through itself without burning itself as a...

Gregor Mendel is known as the father of genetics. He observed that pea plants had certain characteristics that were dominant. He concluded by observing the traits of cross breeding different types of pea plants that traits such as height, flower color, and seed shape were determined by dominant...

Hormones are usually made out of proteins and lipids. Ribosomes  make proteins. Skin is also protein. But most likely, more hormones  are made in a hormone-producing cell (called an endocrine cell) in  a faster turnover than a skin cell. Thus, there would need to be  more ribosomes in the...

Yes, it depends on the depth and lengths on both sides of the river

Do you mean Fantasia?   If so, the dancing mushrooms were dancing to Tchaikovsky's  wonderful Nutcracker Suite.    The mushrooms look like something from the amanita family.    I don't recall them wearing anything that looks like a lace skirt.  It might have been an annulus or veil...
Highly electronegative and highly electropositive elements, e.g.  Fluorine, Clorine, Oxygen, or Nitrogen and Sodium, Potassium,  Rubidium, Cesium or Barium.

If fired with the same momentum yes it does effect the penetration
Half life has unit. That is unit of time. So it has to be  mentioned. Let us assume that half life is 1 year. Okay. Now to  know about the mass remaining we have to get the ratio  (1/2)^1620. Hence remaining will be 1/(2^1620) * mass at the  beginning
You would divide by 2, then by 2 again, then again. (Because 2 to  the 3 is 8)
