The low pressure system wind flow in a counterclockwise direction toward the center because low pressure are connected, and in fact often generally, by upper atmosphere with winds. Winds generally blow from high pressure to low pressure areas at the surface. The direction of deflection is caused by the rotation of the Earth and the resulting Coriolis effect.
A way to remember this is.....some stoners like to get "high around the clock" (as in clockwise, but please don't do this!!)
Low pressure systems usually bring cloudy stormy conditions, while high pressure system bring clear bright skies and in the summer, warm weather.
Physical change there is no energy lost or gain. Basically the physical change is the change of state like melting
Mass percentage of sodium chloride(NaCl) in ocean waters = 3.5 %
That means 3.5 g sodium chloride(NaCl) is present for every 100 g of ocean water.
The given mass of sodium chloride(NaCl) is 45.8 g
Calculating the mass of ocean waters that would contain 45.8 g sodium chloride(NaCl):

= 1309 g ocean water
Therefore, 45.8 g sodium chloride is present in 1309 g ocean water.
Answer:DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Explanation:
Answer: The pressure of the He is 2.97 atm
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given :
=total pressure of gases = 6.50 atm
= partial pressure of Nitrogen = 1.23 atm
= partial pressure of oxygen = 2.3 atm
= partial pressure of Helium = ?
putting in the values we get:
The pressure of the He is 2.97 atm
