tangare [24]3 years ago
5 0

Answer:

The correct answer is C. Earth's outer core contains liquids that conduct electricity.

Explanation:

The dynamo theory is a theory which describes why the Earth and other stars have a magnetic field. The dynamo theory proposes that an electrically conducting fluid, a conventional fluid or a rotating fluid can generate a magnetic field. Hence, these fluids are responsible for Earth's magnetic field.

The Outer core of the Earth exhibits dynamo. This is because Earth contains fluids inside its core which are rotating and driving convectional currents.

In pea plants purple flowers are dominant to white flowers.
algol13

Answer:

100%

Explanation:

This question involves a single gene coding for flower color in pea plants. The allele for purple flowers (P) are dominant to white flowers (p). This means that purple color will be expressed in a heterozygous state.

According to this question, If two white flowered plants are cross i.e. pp × pp, the following gametes will be produced by each of the parent: p and p. Using these gametes in a punnet square (see attached image), ALL (100%) of the offsprings will be white colored (pp).

Therefore, 100% of the offsprings will be white flowered.
