The element starts off as 100%. half of 100% is 50% and half of 50% is 25%. the element has emitted 2 times the half life which is 10,000 x 2 = 20,000
the fossil bone is 20,000 years old
The ratio of yellow seed phenotype with green seed color seed offsprings will be 4:0.
Explanation:
Given that:
Dominant trait is Y (yellow seed color)
recessive trait is y (green seeds color)
cross between YY and yy, According Mendelian Genetics dominant trait will be seen in phenotype as it masks the effect of recessive gene.
Punnet square shows that:
Y Y
y Yy Yy
y Yy Yy
All the plants produced will be tall phenotype.
The yellow seed plant plants will be heterozygous i.e Yy
the phenotype ratio is 4:0
The genotype ratio is 4:0
The genotype of the offspring is Yy
phenotype is yellow colored seed plant.
<span>About the conservation of energy. Suppose you are in a vacuum and you bunch a basketball. You will notice that no matter how much you will leave the ball bunching the ball will never stop. That happens because the ball develops both potential and kinetic energy, the sum of those two give us the mechanical energy which remains constant. We have to suppose that friction is zero otherwise you have to count for thermal loses. </span>I hope that this is the answer that you were looking for and it has helped you.
Answer:
Because mass is constant, while weight depends on gravity.
Explanation:
For example, your mass on Earth will be the same as your mass on planet Mars. Your weight however, will change depending on the force of gravity exerted on you.
