The genetic material of HIV consists of two single stranded RNA molecules.

The side view mirror, in all the vehicles we use only convex mirror. This mirror makes the objects and small to show them in the mirror. That's why in all such mirrors, "Ojects in the mirror are closer than they appear."

We know that, peninsula is a piece of land that surrounded by water on three sides.  Hence, it is what A piece of land almost surrounded by water i.e, three sides water and one side land.

Stoichiometry is a branch of chemistry deals with the calculations on reactants and products. It is based on the Law of conservation of mass where total mass of reactants is equal to total mass of products.

Most producers use sun light for making their energy in the process of photosynthesis. The energy they prepared is sugar and glucose. 

Let the breadth of rectangle be x m.

Then, the length of rectangle = (x+ 6) m

Perimeter of rectangle = 2 (x+x+ 6) m

Therefore, 2 (x+x+ 6) = 84 m

4x+ 12 = 84

4x= 84 –12
4x = 72/4 = 18
Therefore, length of rectangle = 18 + 6 = 24 m = height of triangle

Diagonal of rectangle = √(324+576) = 30 m = base of triangle

Therefore, are of triangle =1/2× base × height =1/2× 24 × 30 = 360 sq. m

We know that,

Mass of Carbon = 12 gms

Mass of Oxygen = 16 gms = O2 => 16 * 2 = 32 gms

=> Mass of 1 mole of CO2 = 12 + 32 = 44 gms.

For neutral atoms, the periodic trends in atomic size can be described like this

Atomic size decreases when going from left to right across a period,
Atomic size increases when going from top to bottom down a group.

Let's use these trends to try and figure out which atom would have the largest radius.

If you look at elements that are located in the same group, potassium will have a larger atomic radius when compared with sodium. Likewise, bromine will have a larger atomic radius when compared with chlorine.

Now focus on potassium and bromine. Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.
