Answer:
X-linked recessive inheritance
Explanation:
Since the disease is primarily present in males vs females, it is a s.ex linked disease.
In X-linked recessive inheritance, males tend to get disease b/c they only have one x (the other is y) which means if they get the bad "x" copy from mom then they definetely will get the disease.
Females can be carriers b/c they are XX. If they get a good copy from mom and suppose a bad copy from dad, they can still be healthy b/c the good copy is dominant. They will be carriers (cuz they have the bad copy) but themselves wont have the disease.
The answer is A. Pollution is harmful substances that can damage organisms and the environment. Decomposition returns nutrients into the soil which helps organisms grow and reproduce. Replenishment is to fill something which would be a good thing. Improvement means to make something better which is also a good thing. Degradation means to degrade or make something worse which is what pollution is doing to organisms and the environment.
Answer:
Sound travels better through solids than through air.
Explanation:
Think about being in the pool: you can hear a lot of things, albeit muffled a little. Or think about tapping a really long pole, and someone standing far away can hear the vibration or the noise while touching the pole.
Solids are more tightly packed together. Sound needs a medium to travel though, and anything with densely packed atoms is better than loosely packed. The hierarchy is solid > liquid > air. Kinda funny that we do most of our talking through air.
