The polar portion of a cholesterol molecule, which forms hydrogen bonds with the polar heads of neighboring phospholipids and glycolipids, consists of a hydroxyl group or -OH. From the name of the molecule, you can easily say that it should contain an hydroxyl group as it has an -ol in its name. Alcohol is a polar molecule so this part of cholesterol should be the polar portion. Cholesterol is a modified steroid and a lipid molecule. It is an important structural molecule of all cell membranes, maintaining fluidity and structural integrity. It is also a starting material for the synthesis of bile acid, vitamin D and steroid.<span />

Explain why world food shortages could be reduced by growing more algae.
Sonja [21]
One of the many awe-inspiring things about algae, Professor Greene explains, is that they can grow between ten and 100 times faster than land plants. In view of this speedy growth rate – combined with the fact they can thrive virtually anywhere in the right conditions – growing marine microalgae could provide a variety of solutions to some of the world’s most pressing problems.

Take, global warming. Algae sequesters CO2, as we have learned, but owing to the fact they grow faster than land plants, can cover wider areas and can be utilised in bioreactors, they can actually absorb CO2 more effectively than land plants. AI company Hypergiant Industries, for instance, say their algae bioreactor was 400 times more efficient at taking in CO2 than trees.

And it’s not just their nutritional credentials which could solve humanity’s looming food crisis, but how they are produced. Marine microalgae grow in seawater, which means they do not rely on arable land or freshwater, both of which are in limited supply. Professor Greene believes the use of these organisms could therefore release almost three million km2 of cropland for reforestation, and also conserve one fifth of global freshwater

alina1380 [7]

mol=35:101.11 g/mol=0.346

formula units = 0.346 x 6.02 x 10²³ = 2.082 x 10²³

What pressure, in atmospheres, is exerted on the body of a diver if he is 38 ft below the surface of the water when atmospheric
Talja [164]

The pressure of diver = atmospheric pressure + water pressure

atmospheric pressure = 750 mmHg (as given) = 750 / 760 atm = 0.987 atm

Water pressure is

P = hρg

where

h = height of water = 38 ft

1 ft = 0.3048

38 ft = 11.58 m

ρ = density  = 1000 Kg / m³

g = gravitational constant  = 9.81 m/s2

P = 11.58 X 1000 X 9.81 = 113599.8 Kg / m s^2 Or N /m^2

1 N / m^2 = 1 pa = 9.869 X 10^-6 atm

P = 113599.8 Pa = 1.12 atm

Total pressure = 1.12 + 0.987 atm = 2.107 atm = 2.1 atm (two significant figures)
