<span>The cause of albinism in one seal in a population of seals with similar coloring is gene mutation. Albinism is a recessive trait caused by a mutation in the gene for the enzyme which is important in melanin synthesis. Since melanin is a pigment responsible for hair and skin colour, the gene mutation will cause the absence of melanin and thus, albinism.</span>
Answer:
Ampere
Explanation:
The ampere is the unit of measurement in the international system. Its equal to a coulomb/second. It can be describe as the rate of charges flowing throught a conductor
Answer:
1) electric current - ampere
2) force - joule
3 frequency - hertz
4) density - kilogram per cubic metre

Answer:
6.4 J
Explanation:
m = mass of the bullet = 10 g = 0.010 kg
v = initial velocity of bullet before collision = 1.8 km/s = 1800 m/s
v' = final velocity of the bullet after collision = 1 km/s = 1000 m/s
M = mass of the block = 5 kg
V = initial velocity of block before collision = 0 m/s
V' = final velocity of the block after collision = ?
Using conservation of momentum
mv + MV = mv' + MV'
(0.010) (1800) + (5) (0) = (0.010) (1000) + (5) V'
V' = 1.6 m/s
Kinetic energy of the block after the collision is given as
KE = (0.5) M V'²
KE = (0.5) (5) (1.6)²
KE = 6.4 J
