What is widow's peak?

http://en.wikipedia.org/wiki/Widow%27s_peak

Ozone layer only absorbs/blocks the UV rays and does not affect the heat coming into earth

Direct rays(or UV rays) is not heat
So the sun's heat will get directly into earth but the UV rays will be partially get into earth

[quote=\"PsleStudent\"]The gas called ozone protects the earth from the direct rays from the sun by forming a layer in the atmosphere. If not this layer the heat of the sun will get to the earth directly. When this ozone layer is depleted through the action of some chemicals man has no shelter again from the ultraviolent rays of the sun which can cause sunburn and skin cancer. There are also other negative effects of this ray from the sun.

But is the ozone layer completely depleted? If not, then the sun won't directly heat the Earth, right?

hmm... As for that i think for that, your opinion should be correct. As i think the ozone layer is not COMPLETELY depleted,there will still be a shelter but i think there would be more UV rays passing through the ozone layer? i am also not so sure about that... [/quote]

432 / 4 = 108, so it means the number is the last number in the 108th row.

In editing, there is this sentence

\"Deceiving sellers would replace the chickens with stray cats.\"
They are supposed to change the word form of 'deceiving'. He put as 'deceivious' but I think it should be 'deceitful'.

Any comments?

I thought deceptive is the adj.

What is the answer for deceiving in editing.

No one in my DS’s class knows it

Can we use 2 calculators in PSLE.
