He used Pea plants to help him find the laws of inheritance. He crossed homozygous (AA) tall plants with short (aa) plants and found that all of the off spring were tall, due to the fact that tall is dominant and short is recessive. He then conducted another experiment where all the offspring mated (all offspring were heterozygous (Aa)) And produced the F1 generation and 25 percent of the plants were short (use a punnet square to see why) and 75 percent were tall.
I hope this response helped :) If u have anymore q about mendelian genetics pls lmk !
What is the second question? If it is in a picture I cannot see it, just comment the question below and I'll see if I can help you :3
Plants respond immediately to the gravitational attraction of the Earth as well as to light. Stems develop away from the center of the Earth and toward the light due to negative gravitropism.
<h3>What is negative gravitropism?</h3>
Negative gravitropism occurs when shoots develop in the opposite direction of gravity toward sunlight.
Plants respond immediately to the gravitational attraction of the Earth as well as to light. Stems develop away from the center of the Earth and toward the light due to negative gravitropism.
Thus, the given experiment shows negative gravitropism.

Solar eclipses occur more often than lunar eclipses because in a lunar eclipse, the moon has to be perfectly aligned with both the earth and the sun.
Solar eclipses occur about 2 to 4 times per year, but the area
on the ground covered by totality is only about 50 miles wide. In any
given location on Earth, a total eclipse happens only once every hundred
years or so, though for selected locations they can occur as little as a
few years apart.
Eclipses of the Moon by the Earth's shadow occur less often than solar eclipses, however, each lunar eclipse is visible
from over half the Earth. At any given location, you can have up to
three lunar eclipses per year, but some years there may be none.
In any
one calendar year, the maximum number of eclipses is four solar and
three lunar.
The answer is qualitative
