Answer #1

1) Chlorophyll is the pigment found in the leaf which is the most important pigment for photosynthesis. With this pigment, plants conduct photosynthesis in green light.

2) Leaves are colored due to the pigments present in it. Chlorophyll, a pigment present in leaves, gives it a green color. It is important to produce food using sunlight. During spring and summer when there is plenty of sunlight, plants make a lot of chlorophyll.

The change in colors in leaves are caused by changes in the pigments. When the weather changes, some plants break down all the green pigment. This lets beautiful yellows, oranges, and reds come through in the fall.

3) The quality of the fall foliage depends on weather, temperature and precipitation.

Momentum and collisions Formula for Oomph An important physical quantity, the name of which we’ll give later, corresponds to the intuitive idea of oomph. The more oomph something has, the harder it is to stop, and the more ability it has to knock other things over. Let’s figure out the formula for oomph . A small pebble and a larger rock are thrown at the same speed. Which one has more oomph? Why? The rock is twice as massive as...

Activity 1: Scientific Reports You may have heard the question “If a tree falls in a forest and no one is around to hear it, does it make a sound?” A similar question can be asked about experiments. “If a researcher performs an experiment and never publishes the result has science been performed?” Many people would say no because science is the accumulation of knowledge. If the results of an experiment are not published, knowledge is not gained. The final...
