As the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.
<h3>
What is Kepler's second law?</h3>
Kepler's second law of planetary motion describes the speed of a planet traveling in an elliptical orbit around the Sun.
This law exaplains the speed of planets around the sun, the speed of the planet increases as it nears the sun and decreases as it recedes from the sun.
From the findings, the astronomical unit of the Mercury is 0.387 and the orbital period is 0.24 year.
From the equation above, as the semimajor axis of a planet increase, the orbital period will decrease and the speed of the planet will decrease.

Answer:
A. Most plats in the ditch will be plants with long roots.
Explanation:
Because the plants with shallower roots systems are easily uprooted by the rain, and there is lots of rain that year, natural selection will choose the long rooted plats. They are the "strongest" in evolution's eyes because they are less likely to die by being uprooted.
Answer:
<h2>B) BB</h2>
Explanation:
The gene for feather color is controlled by codominance ( codominance, when both the alleles express their effect, the phenotype is the combination of both alleles, it is the intermediate of both phenotypes).
black feathers is B
erminette feathers WB
white feathers is W
Then the genotype for chickens with black feathers is BB.
also the Bb may be black this is heterozygous condition.
