Answer:
Adenine binds to guanine.
Explanation:
Rules of the base pairing are:
A with T
Purine base, adenine (A) pairs with the pyrimidine base, thymine (T).
C with G
Pyrimidine base, cytosine (C) pairs with purine base, guanine (G).
<u>(Option A is correct).
</u>
<u>(Option B is incorrect).
</u>
Nitrogenous bases are positioned in the inside helix structure like the rungs of a staircase due to hydrophobic effect and are stabilized by hydrogen bonding.
<u>(Option C and D is correct).
</u>
Answer:
Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. The first step in is glycolysis, the second is the citric acid cycle and the third is the electron transport system.
Answer:
São Paulo is a city in Brazil that faced the worst drought in Brazil in the last 100 years between 2014–17.
The reason of the drought was diminished rain falls from last three third consecutive year in the region. Humans were somewhere responsible for the drought and less rainfall because this was caused by expansion of deforestation into the Amazon basin. Deforestation disturbed the environmental cycle that caused less amount of rain in São Paulo, Brazil.
Answer:
Explanation:
A number of things/people that populate on place
Answer:
- They allow for more collisions of molecules (enzymes + substrates)
- They lower the amount of activation energy needed to complete the reaction.
- They speed up chemical reactions to form more products
Explanation:
Enzymes are proteinous molecules that serves as catalyst in living systems. Like every other catalyst, enzymes function to SPEED UP the rate of biochemical reactions by LOWERING/REDUCING the activation energy, which is the energy required for a reactant to form product (completion of reaction).
Enzymes like other catalysts causes faster movement of molecules in the reaction i.e. they allow for more collisions of molecules (enzymes + substrates). This causes the rate of reaction to increase and hence, speeden the reaction.
