How would you write this number in scientific notation? (Use the carrot key to denote an exponent. ex: 6.02 x 10^23)

NeTakaya

Answer:

$D=5.89\times 10^{12}\ km$

Explanation:

The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.

A number can be written as $x.0\times 10^y$ in scientific notation where x is a real no and y is any integer.

There are 10 zeros in the given number and also there are 12 digits after. It would mean that,

$D=5.89\times 10^{12}\ km$

So, the distance in scientific notation is : $D=5.89\times 10^{12}\ km$

t-dwarf plant

TT- means the plant is homozygous tall i.e the allele T is the same 100% talk

Tt- means the plant is heterozygote tall which implied that though this plant express tallness its still have gene for shortness hidden in its cell and if crossed with a plant that is dwarf some of the offspring will be dwarf.

From the test cross all the gametes are heterozyote - Tt Tt Tt Tt
