Most of the metal we throw away at home comes from food and drink cans and aerosols. Typically food cans are made from steel, which can be melted down and turned into new food cans. Drinks cans are generally thinner and lighter and made from aluminum, which can also be recycled very easily. Mining aluminum is a very energy-intensive and environmentally harmful process. That's why waste aluminum cans have a relatively high value and why recycling them is such a good thing to do.
One problem with recycling paper is that not all paper is the <em>same</em>. White office printer paper is made of much higher quality raw material than the paper towels you'll find in a factory washroom. The higher the quality of paper waste, the better the quality of recycled products it can be used to make. So high-grade white paper collected from offices can be used to make more high-grade white recycled paper. But a mixture of old newspapers, office paper, junk mail, and cardboard can generally be used only to make lower-grade paper products such as "newsprint" (the low-grade paper on which newspapers are printed). Corrugated cardboard (which is held together with glue) is harder to recycle than the thin cardboard used to package groceries.
In conclusion, metals are almost all the same. There are a variety of different papers, (paper towel, cardboard, etc) so it is very hard to recycle that if they are all different.
Hope this helped!
Scientists claim that Bisphenol A when ingested may cause brain problems, behaviour and reproductive development problems in foetus, children and even infants.
Option D.
Explanation:
Bisphenol A was a very common compound to produce polycarbonate bottles. This bottles were very commonly used to produce baby bottles, different beverage containers, different water bottles etc. Until 2010, BPA was allowed as a safe to consume ingredient by WHO but after 2010,they strictly restricted the levels of BPA in food because it has severe ill effects in human body.
Even low amounts of BPA in food can cause hypertension, coronary heart disease, atherosclerosis etc. Although not proven, but BPA is thought to cause cancer. Effects on children and infants are more prominent which can cause problems in development of reproductive structures and brain. Even in adults, the brain problems may lead to change in their behaviors.
Answer: there is no gravity and no type of life on the moon therefore basically making it a huge target.
Explanation:
Answer:
Underneath the leaf's epidermis is the ground tissue. This is divided into the palisade mesophyll and spongy mesophyll. The spongy mesophyll
allows for the gases that entered through the stomata to be exchanged during photosynthesis. The palisade mesophyll is where the majority of
photosynthesis takes place.
Explanation:
Arteries are generally larger, undergo more blood flow, and exhibit more blood pressure.
Veins are smaller than arteries, and can have valves in certain parts of the body.
