Answer:
"Option B. The tilt of the moon´s orbit around the earth
" limits the number of eclipses per year
<u>Explanation</u>:
The moon's orbit is tilted only by 
. Around the sun when the earth and moon move, the tilt of the moon changes according to the direction of the sun. When the same thing occurs to the earth, the seasonal changes occur. The theory is all related to moon's formation. Due to this tilt the moon's road near the stars changes slightly in every month. The inclination is with respect to the ecliptic plane. If this inclination was absent then we could have felt the eclipse more frequently.

Answer:
She is using Karyotyping
Explanation:
A karyotype is the number and visual appearance of the chromosomes in the cell nuclei of an organism or species.
Depending on the structure of cells (shapes and organelles) we can differentiate cells and therefore create different groups and classifications based on their differences and functions.
The eukaryote-prokaryote division bases itself on the possesion of a nucleus that creates a boundary for the genetic materifal. In this case, eukaryotes have it while prokaryotes don't.
