used cross breeding to purposely breed plan
studied a variety of pea plant traits
studied several generations of plants
In order to breed or cross one plant with another, Mendel opened the petals and removed the anthers from the flower and dusted the pistil with pollen from the plant he wished to cross it with and covered the flower with a small bag to prevent the pollen in the air from landing in the pistil. This process is called cross pollination.
Mendel considered 7 characters of pea plant for his study and did the study for several generations.
Answer:
15.67 m/s
Explanation:
The ball has a projectile motion, with a horizontal uniform motion with constant speed and a vertical accelerated motion with constant acceleration g=9.8 m/s^2 downward.
Let's consider the vertical motion only first: the vertical distance covered by the ball, which is S=50 m, is given by
where t is the time of the fall. Substituting S=50 m and re-arranging the equation, we can find t:
Now we now that the ball must cover a distance of 50 meters horizontally during this time, in order to fall inside the carriage; therefore, the velocity of the carriage should be:
Answer:
A microwave
Explanation:
Car
Lightbulb is a really good one
Same with the sun. That one has Chemical as well
Gas "floats" so if there are examples or pictures it would be the one with the most evenly spread out "dots".
