The first answer because it’s natural selection when the weak die off the the strong get stronger also the strong produces more which stops antibiotics form working which is why we have antibiotics consistently changing
Answer:
Ice Age Explanation. Fluctuations in the amount of insolation (incoming solar radiation) are the most likely cause of large-scale changes in Earth's climate during the Quaternary. In other words, variations in the intensity and timing of heat from the sun are the most likely cause of the glacial/interglacial cycles.
Explanation:
Answer: By storing carbon above and below the ground, the trees and plants in forests contribute to the production of oxygen as a byproduct of photosynthesis. ... Photosynthesis provides most of the oxygen that humans and animals breathe.
A solstice is a point during the Earth's orbit around the sun while during an equinox, the sun is at its nearest point from the Equator. Another difference is that a solstice takes place on June 21 and December 22, while an equinox takes place on March 20 and September 22. One more difference is that during the summer solstice, the days are longer and in winter solstice, the nights are longer. For an equinox, the duration of day and night are both equal.
Hope it helps :)
Answer:
The rate would increase.
Explanation:
Activation energy is the energy needed for a chemical reaction to start while the rate of reaction is how a reactant turns into the product. Catalysts are used to speeden up the rate of a chemical reaction.
The catalyst do this by lowering the activation energy needed for the reaction to occur, leading to the increase in the rate at which the same reaction occurs. It should be noted that a catalyst is not a reactant, neither does it get used up in the chemical reaction. It just provides an alternative energy pathway with a reduced activation energy, hereby, helping the reaction to proceed faster than it would without the catalyst.
