false

Explanation:

The half-life of C-14 is shorter than that of U-238. Every radioactive isotope have their distinct and unique half-life.

  • The half-life of an isotope is the time taken for half of the radioactive nuclei to disintegrate.
  • The shorter the half-life, the faster an isotope decays.
  • C-14 has an half life of 5700 years. It is used for dating archaeological materials.
  • U-238 has an half life of 4.5 billion years. It has been used to date the age of the earth.

In rabbits, black fur (B) is dominant to white fur (b). A purebred black furred male is bred with a female that had the recessiv
ValentinkaMS [17]

Answer:

All the offsprings will be black-furred (Bb)

Explanation:

This question involves a single gene coding for fur length in rabbits. The allele for black fur (B) is dominant to the allele for white fur (b). This means that a rabbit heterozygous for this gene (Bb) will have a black fur.

According to this question, a purebred black furred male (BB) is bred with a female that had the recessive white fur (bb). The parents will produce gametes as follows:

BB - B only

bb - b only

Using these gametes in a punnet square (see attached image), the genotypic proportion of the produced offsprings is as follows:

Bb, Bb, Bb, Bb

All Bb (heterozygous) means that all of the offsprings will be black-furred.

What distinguishes an amniotic egg from eggs laid by other animals, including fishes, amphibians, and invertebrates?
PIT_PIT [208]

The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage

<h3>Characteristics of an amniotic egg</h3>

Eggs laid by amniotes are different from other eggs laid by fishes, amphibians and invertebrates in that they lack a membrane and a larval stage. the shell of the amniotic egg protects the embryo in the absence of a membrane. The shell also allows for the exchange of oxygen and carbon dioxide between the the embryo and the environment.

Hence we can conclude that The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage
