Answer:
Hi there!
Your answer is:
Dependent variable: Plant growth
Independent variable: Day length
Explanation:
The independent variable is Intentionally manipulated by the researchers. We know exactly what it will be each day, because we control it! Since the scientists are controlling the day length, that is your independent variable.
The dependent variable is NOT manipulated by the researchers. We are studying what the dependent variable does in reaction to the changing independent variable. Since we are recording & studying how the plant grows based on the day length, that is your dependent variable!
I hope this helps!
Answer:
Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.
In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .
Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.
These compounds interact with one another and end in “life”.
So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

Hopefully I was able to help you with the concept. Good luck!
Hypothalamus
When there is abnormally high internal temperature, sensors
in the Central Nervous System send signals to the hypothalamus. The hypothalamus initiates thermoregulation
by sending messages to various organs and body systems with a various
mechanisms. High temperature will set off sweating and vasodilation to cool down
the body.
Because they can move faster than you. And when you move your ands to the fly it looks like it’s in slow motion
