The last one, " Scientists predict a volcano will erupt based on current volcanic activity." This one is false because they actually predict a volcanic eruption by the volcanic waves and other complicated things.
Answer No 1:
A concentration gradient can be described as a phenomenon by which molecules travels from an area which is highly concentrated to an area which has low concentrations of that molecule.
Answer No 2:
A molecule is said to be diffusing down a concentration gradient when molecule acquire the phenomenon of concentration gradient i.e move from higher concentration to lower concentration. This mechanism is also termed as passive transport. Active transport is the opposite of passive transport. In active transport, molecules move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration.
Answer:
The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. Every second, 600 million tons of matter are converted into neutrinos, solar radiation, and roughly 4 x 1027 Watts of energy
Explanation:
The answer is c. last time i had that and my teacher said it was c
Answer:
C. Removing this step decreases the amount of carbon in the air: This is correct, removing factories would decrease the emission of greenhouse gases, thus decreasing CO2 in the atmosphere.
Explanation:
When we look at the picture we can see that the line that goes from G to C, goes from a factory to the atmosphere. As we know factories release a great number of elements into the atmosphere being one of them, carbon dioxide. Therefore taking into consideration we can proceed to analyze the following statements.
A. Removing this step prevents photosynthesis in the next step: This is not true industry increases carbon dioxide in the atmosphere, even if they don't exist there is enough CO2 for plants to perform photosynthesis.
B.Removing this step increases the amount of carbon in the soil: This is not true as factories release carbon dioxide to the atmosphere, not the soil.
C. Removing this step decreases the amount of carbon in the air: This is correct, removing factories would decrease the emission of greenhouse gases, thus decreasing CO2 in the atmosphere.
D. Removing this step increases carbon storage in plants: This is incorrect the carbon storage in plants is cording to their necessities independently of the abundance in CO2, in the atmosphere.
