An elongated tailbone occurs rarely in some newborn children. What does the presence of a tailbone indicate?

1 answer:

4 0

<span>It's because the genome has undergone mutation which means the foetus has a post anal tail and when the fetus matures the genome triggers absorption in development to remove unnecessary components by disintegrating the unnecessary cells (webbing, tail, etc). When this is not removed it is because the genome did not send the signal for absorption.</span>

A4 kg object possesses 18 J of kinetic energy. What is its velocity?

Digiron [165]

Answer:

velocity = 3 m/s

Explanation:

kinetic energy = 1/2 * mass(kg) * velocity²

Using the formula:

18 = 1/2 * 4 * velocity²

9 = velocity²

velocity = 3 m/s

In sheep, white wool is dominant over spotted wool. If 10 purebred white wool sheep (TT) are crossed

Anon25 [30]

Answer:

Explanation:

This question involves a single gene coding for wool color in sheeps. The allele for white wool (TT) is dominant over the allele for spotted wool (tt). This means that a sheep with an heterozygous genotype (Tt) will be white-wooled.

In this cross, 10 purebred white wool sheep (TT) are crossed with 10 spotted wool sheep (tt). This will give rise to all offsprings with heterozygous genotype: Tt (see attached image for punnet square). Since, white wool (T) is dominant, all the offsprings will have a white wool and none i.e. 0 will have a spotted wool.
