Answer:
The correct answer would be 1/32
Explanation:
Mary and Justin can have affected child only when both of them are carriers that is, both of them should be Gg.
The probability of Justin's father to be a carrier is 2/4 or 1/2 [1 GG: 2Gg: 1gg].
Similarly, the probability of Jean to be a carrier would be 1/2.
Thus, the probability of Justin and his father to be a carrier would be equal to 1/2*1/2 ⇒ 1/4.
The probability of Mary to be a carrier = 1/2.
So, the probability of Mary and Justin to be the carrier of the disease would be 1/2*1/4 = 1/8.
Now, the probability of having an affected child would be 1/4 as it is a recessive disorder.
So, the probability of Mary and Justin to have an affected child = 1/4 * 1/8 ⇒ 1/32
Answer: True
Explanation: Dark energy is the name given to the mysterious force that is accelerating the rate at which our universe is expanding. ... Some repulsive force is pulling the universe apart and this force was dubbed “dark energy”. Riess and Livio describe the three main hypotheses to explain the nature of dark energy. The leading theory to explain the accelerating expansion is the existence of a hypothetical repulsive force called dark energy. ... "Usually this repulsion is ascribed to a mysterious dark energy that would uniformly permeate the cosmos, but nobody knows what it is nor why it behaves this way," Villata said in an email. Dark energy is believed to be responsible for the expansion of the universe, counteracting gravity, and is considered to be the fifth force acting on matter, after gravity, the electromagnetic force, and the strong and weak nuclear forces.
