Answer: C. Shadow length decreased from sunrise to noon.
Explanation: Think about how the sun is positioned in the sky. If it was noon, the sun is above the stick which means little to no shadow at all. If the sun was rising, its hitting one side of the stick, making the shadow longer.
Answer:
No.This is because the amount of the chlorophyll; ls not a limiting factor of photosynthesis.
Explanation:
Generally the three factors are regarded as the limiting factors of photosynthesis.These are the CO2 concentration,light intensity,and temperature.Fluctuations in the availability of these factors affects the rate of photosynthesis.
When the rate of a chemical reaction depends on a lot of reactions for its progress.The rate of this reaction is determined or limited by the slowest in the reactions. This series of reactions govern this chemical reactions are the limiting factors. The one that is slowing down the rate of the reaction is said to limit it.
in the case of photosynthesis, a decrease in the amount of CO2,but no change in the amount of other factors would affect the rate of photosynthesis. This is applicable to other factors fluctuation too ,which limits the rate of photosynthesis
Answer:
The correct option is B.<u> It was mostly incorporated into proteins that regulate and manage metabolic reactions.</u>
Explanation:
The results of the experiment showed that most of the radiolabeled amino acids were present in the mitochondria.
Amino acids can be described as organic compounds which build up the proteins. There are 20 different kinds of amino acids which make up different kinds of proteins, each specified to perform specific functions.
The results from the experiment prove that the radiolabeled amino acid is being used to make proteins that are necessary for metabolic reactions.
When the temperature reaches 0˚C (32˚F), the top layer of the lake freezes and turns into ice. In solid form, water molecules are less dense and thus ice floats on the top of the lake.
This solid barrier prevents any wind-induced mixing as well as protects the relatively warm water underneath. Furthermore, light is also blocked so that photosynthesis is inhibited during this period. As the lake water is separated from the atmosphere, no direct oxygen diffusion occurs.
All these factors together causes a more even distribution of nutrients and gases in a lake in winter.
Human trials have indicated an inverse relationship between blood lead level and calcium intake. While milk isn’t an antidote to let’s say, lead poisoning, the dietary calcium inhibits the lead absorption. This sort of poisoning is incredibly dangerous to the systems of the human body, and the ingredients within the milk help to defend against it. The purpose of the milk is to dilute the ingested poison.
