In the fall, a leaf can turn various shades of red, orange, yellow, or brown.
Yes.
The most vibrant leaf colors in fall are typically red, orange, and yellow.
We know that air resistance (or atmospheric drag) is what causes a leaf to fall more slowly than a penny. A large leaf that weighs a much as a penny has a much greater surface area than the penny, and all this surface area means that the leaf has more drag. Though the leaf and penny will be accelerated by the same amount of force (because they have the same mass), the leaf will present all that surface area to the air, and this will set up a condition of high drag.
When a leaf is boiled in alcohol, the chlorophyll in the leaf is extracted and dissolves in the alcohol. The alcohol may change color depending on the pigments present in the leaf, such as turning green if chlorophyll is present.
because i poo heaps in the fall so the leafs fall because it smells like poo
Fall is the present tense of the past participle fallen.
a process called abscission helps in leaf fall. in this process the cells at the stalk end, from where leaf is attached to the branch of tree, start to die resulting in abscission(death ) of leaf
When iodine is dropped onto a leaf, it reacts with starch present in the leaf to form a blue-black color. This color change is used to test for the presence of starch in the leaf tissue. Absence of blue-black color indicates that starch is not present in the leaf.
