Fall brilliance of the leaves is a result of chlorophyll decomposition, which causes the green color to disappear and the yellow to orange hues to appear.
What is chlorophyll brake down hypothesis?If plants degrade the chlorophyll and move it out of their leaf before the leaves fall, they can save energy.
Plants are capable of reabsorbing the substances that go into making chlorophyll. However, due to changes in temperature and daylight hours in the fall, the leaves stop generating food.
As a result, during the summer, chlorophyll is continuously degraded and rebuilt in tree leaves.
Therefore, chlorophyll brake down hypothesis that explains why you think leaves change color in the fall.

The time it takes to run a mile depends on the person running speed what is the independent and dependent variable as well as the constants
Independent: The person's running speed
Dependent: The time it takes to run a mile
Constants: The mile.
-------
The independent variable stands on it's own. It will not change based on the Dependent Variable.
The dependent variable, the time it takes a person to run a mile, will change based on the Independent Variable, the person's running speed.
The constant is the mile. In an experiment, the mile, will stay the same. In each trial, it will stay the same, unlike the data for the independent and dependent variable.
Which of these changes would most likely lead to exponential growth in
population?
an increase in the predation on the population
a decrease in the habitat size of the population
an increase in the amount of food available to the population
a decrease in the amount of water available to the population
Answer:
It is an increase in available food amount.
Explanation:
An increase in predators would result in the prey species dying off. A decrease in habitat size would result in the species not having a place to live or hide from predators. A decrease in amount of available water would make the species die of dehydration.
The prey species would disappear as there would be more predators. The species wouldn't have a place to reside or hide from predators if the habitat's size shrank.
What is the exponential growth?If the amount of water available decreased, the animal would become dehydrated and die.
An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.
Linear growth, which is additive, and geometric growth can be contrasted with exponential growth, which is multiplicative.
Therefore, The prey species would disappear as there would be more predators. The species wouldn't have a place to reside or hide from predators if the habitat's size shrank.

Which option is food (i.e., an energy source) for a plant?
carbon dioxide that a plant takes in through its leaves
minerals that a plant takes in from the soil
water that a plant takes in through its roots
sugars that a plant makes
Answer:
I'm pretty sure that it is the water the plant takes through its roots
Explanation:
Their roots take up water and minerals from the ground and their leaves absorb a gas called carbon dioxide (CO2) from the air. They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means 'making out of light'. The foods are called glucose and starch. which is the process of making food for plants
