Answer:
The question 7 answer is false
the question 8 answer is true
Kepler stated three laws of planetary motion.
First law states that the pathway of a planet is an ellipse with the Sun at one of the foci.
Second law states that an imaginary line joining the Sun and a planet sweeps out equal areas during equal lengths of time.
Third law states that the square of the period of the orbit of a planet is directly proportional to the cube of the length of the distance from the Sun.
Therefore, the answer is that Kepler's second law of planetary motion states that planets cover the same area during equal time periods.
Answer:
B) The volume is the same for any gas.
Explanation:
Considering the ideal gas equation as:-
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 8.314 J/ K mol
At STP,
Pressure = 1 atm
Temperature = 273.15 K
So, applying the values we get that 1 mole of any gas occupies a volume of 22.4 L
Thus, correct option is:- B) The volume is the same for any gas.

finches that Darwin studied in the Galapagos islands have evolved with
different types of beaks: drilling, cracking, tearing, and fishing. This
is an example of B. adaptive radiation.
These birds have adapted to their environment - they needed to drill, crack plants, fish, etc. so their beaks have changed and adapted so as to fulfill those needs.
Predation is used for hunting smaller animals, warning coloration refers to a change of color, and protective resemblance refers to an animal blending with its surroundings.
