Why is a low pressue area like the one in the map created along a cold front?
Answer:
Cold, dense air squeezes its way through the warmer, less-dense air, and lifts the warm air. Because air is lifted instead of being pressed down, the movement of a cold front through a warm front is usually called a low-pressure system.

How does stratospheric ozone vary on Earth? (1 point)
O Levels are higher near Antarctica than near the Arctic.
O Levels are higher near the equator than near the poles.
O Levels are higher near the equator than near the Arctic.
O Levels are higher in mid-latitudes than near the equator.
The stratospheric ozone vary on Earth because the levels are higher near the equator than near the poles.
What is stratospheric ozone?Stratospheric ozone is an atmospheric layer of the earth that naturally filters the ultraviolet radiation from the sun.
High concentrations of stratospheric ozone are found at altitudes from 26 to 28 km of the equator and from about 12 to 20 km toward the poles.
Therefore, the stratospheric ozone vary on Earth because the Levels are higher near the equator than near the poles.

a. How many atoms of each type of atom are present in the reactants?
b. How many atoms of each type of atom are present in the products?
There are, 7 Carbon atoms, 10 Oxygen atoms, 12 Hydrogen atoms in the reactants and 1 Carbon atom, 3 Oxygen atoms, 2 Hydrogen atoms in the products.
How to count the number of atoms in reactants and products?Write down the chemical formula that is:[tex]C_{6} H_{12} O_{6}[/tex] + [tex]O_{2}[/tex] → [tex]CO_{2}[/tex] + [tex]H_{2} O[/tex] + [tex]ATP[/tex] List all the atoms present in the equation:
C
H
O
Count the number of atoms of the element of each molecule in the reactant.C=6
O=8
H=12
Count the number of atoms of the element of each molecule in the Product.C=1
O=8
H=2
Hence there are, 6 Carbon atoms, 8 Oxygen atoms, 12 Hydrogen atoms in the reactants and 1 Carbon atom, 3 Oxygen atoms, 2 Hydrogen atoms in the products.

If you are heating water on stove why does it take a while for the water to boil
Answer:
Common sense should tell you the answer!
More water = more mass = more time, basic school physics.
Explanation:
If heat energy is supplied at a roughly constant rate by the heat source then the time taken to supply the total energy needed to boil is calculated from E = Pt. The energy required simply depends on the mass of water. E = m x SHC x temp change. so t = m x SHC x dT/P.
Answer:
Because the pan/pot has to get to the right temp first.
Explanation:
The water boils at a lower temperature. So the pan will boil faster as it doesn't have to reach 100 degrees C to boil the water.
Giraffe ancestors with slightly longer necks were able to reach taller food sources; these organisms survived longer and produced more offspring with the favorable variation
A: artificial variation
B: natural variation
C: both
Answer:
B
Explanation:
Its natural variation because by random mutation some giraffe had longer necks than others. However these longer necks were more favourable and allowed giraffe to survive to reproductive success. Hence the longer necked giraffes had more offspring and this randomly generated trait was passed on to more and more giraffe offspring.
