Answer

Brief Explanations:

Question 14:

Since both parents have freckles (dominant trait) but some of their children don't, they must be heterozygous (Ff) as two heterozygous parents can produce both freckled and non - freckled offspring through Mendelian inheritance.

Question 15:

Igneous rocks are formed from the cooling and solidification of magma or lava. Volcanic activity involves the eruption of magma onto the Earth's surface or intrusion into the crust, leading to igneous rock formation.

Question 16:

The relationship between wavelength ($\lambda$) and frequency ($f$) in the electromagnetic spectrum is given by $c = \lambda f$ (where $c$ is the speed of light). So, long wavelengths correspond to low frequencies.

Question 17:

On a level basketball court, when a ball rolls to a stop, friction between the ball and the court surface opposes its motion, and gravity acts on the ball pulling it downwards.

Question 18:

According to Newton's law of universal gravitation, every mass exerts a gravitational force on every other mass, regardless of their size or state of motion.

Answer:

  1. A. Ff and Ff
  2. C. volcanic activity
  3. B. They have low frequencies.
  4. C. gravity and friction
  5. D. Every mass exerts a gravitational force on every other mass.
