Answer:

The answer is 25% red : 50% pink : 25% white

A - allele for red flowers

a - allele for white flowers

AA - flowers with red flowers

Aa - flowers with pink flowers

aa - flowers with white flowers

The cross looks like:

Parents:          Aa     x     Aa

Offspring:    AA    Aa   Aa    aa

Red flowers (AA): 1/4 = 0.25 = 25%

Pink flowers (Aa): 2/4 = 0.50 = 50%

White flowers (a): 1/4 = 0.25 = 25%

A and B are experiencing winter. The picture which isn't available here in this question is attached below.

Option C.

<h3><u>Explanation:</u></h3>

The earth is tilt by an angle of 23.2° to the vertical plane. This makes the seasonal variation of earth, because in some time of the year, the northern hemisphere faces the sun directly, experiencing summer and then southern hemisphere is away from summer experiencing winter and vice versa. The summer occurs when the place directly faces the sun. And the winter happens when the place obliquely faces the sun or doesn't face the sun at all.

Here in this diagram, we can see that the points A and B are the north pole and the part in northern hemisphere respectively which aren't facing the sun directly, whereas C and D are facing the sun. Thus the southern hemisphere is experiencing summer and the northern hemisphere the winter.

How many moles are there in 78.3g of CO2?
oksano4ka [1.4K]
The molar mass of CO2 can be calculated as follows;
CO2 — 12 + (16x2) = 12+ 32 = 44 g
Therefore molar mass of CO2 is 44 g/mol
In 44 g of CO2 there’s 1 mol of CO2
Then 1 g of CO2 there’s 1/44 mol of CO2
Therefore in 78.3 g of CO2 there’s — 1/44 x 78.3 =1.78 mol of CO2
