Answer:A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.

List 3 possible futures for the universe
Marina86 [1]

1 possible future is The Big Crunch. This theory assumes that the average density of the universe will be enough to stop its expansion and begin contracting.

2. Some theorists state that the expansion of the universe will go on forever, and if that happens, the universe will cool as it expands, and then it will become too cool to sustain life.

3. The Big Rip. The universe may keep expanding, as I mentioned before. But as it expands, the gravity may not be able to hold all the planets together, as it is now. Galaxies would tear apart first, followed by smaller black holes, planets and stars. Eventually, space would start expanding faster than the speed of light, and atoms would start breaking down into super small particles and everything would fall into nothing.

Congenital analgesia is a rare autosomal recessive trait. What is the likelihood that the first two offspring of a cross between
telo118 [61]

The likelihood that the first two offspring of the cross will have congenital analgesia would be 1/16

<h2>Autosomal Recessive Traits</h2>

For autosomal recessive traits, two recessive alleles are needed for the trait to manifest while one recessive allele means heterozygosity.

In this case, let us assume that congenital analgesia is represented by the allele b; heterozygous individuals will, thus, be Bb.

            Bb    x    Bb

          BB   Bb   Bb   bb

Probability of producing unaffected offspring = 3/4

Probability of producing affected offspring = 1/4

Likelihood of the first two offspring having congenital analgesia = probability of first having congenital analgesia and the second having congenital analgesia

    = 1/4 x 1/4

        = 1/16
