Answer: 25 joules
Explanation:
Recall that kinetic energy is the energy possessed by a moving object.
So, kinetic energy = 1/2 X Mass X Velocity^2
Mass = 0.5kg
Velocity = 10m/s^2
= 1/2 x 0.5kg x 10^2
= 0.5 x 0.5 x 100
= 25 Joules
Thus, the kinetic energy of the moving ball is 25 joules
C, bushes and shrubs, mosses, lichens, grasses and annual flowers, trees

Answer:
B- A cleft chin is due to a dominant allele
Explanation:
A husband and wife both having the phenotype for cleft chin and producing an offspring without a cleft chin, indicates heterozygousity in their genotype.
With the heterozygous genotype however, they both expressed the phenotype for cleft chin, indicating that the allele for cleft chin is dominant over the allele coding for normal chin.
Since both parents are heterozygous for cleft lip, the sequence of genotype in their offspring will be:
- 25% chance of having homozygous cleft chin
- 50% chance of having heterozygous cleft chin
- 25% chance of having homozygous normal chin
Because of the dominance of the cleft chin allele, both homozygous and heterozygous forms of the cleft chin allele, will be expressed in the offspring and only the offspring homozygous for normal chin will not express this allele.
