2/4 = 50% of the offsring will be heterozygous
<span>Chemicals are used for the communication between two cells whether the communication is from surface to surface or direct or through receptors. So the chemicals that send instructions to cells are A, T, C, and G in DNA which is four nucleotide bases called as adenine, thymine, cytosine and guanine.</span>
Final velocity after 5 sec is 16 m/s
<u>Given that;</u>
Initial velocity = 4.5 m/s
Constant acceleration = 2.3 m/s²
Time taken = 5 second
<u>Find:</u>
Final velocity
<u>Computation:</u>
Using first equation of motion;
v = u + at
v = 4.5 + (2.3)(5)
v = 4.5 + 11.5
v = 16 m/s
Final velocity = 16 m/s
