Answer:
true
Explanation:
Pollen grains help scientists identify plants and make assumptions on past climate conditions. understand tree growth and make assumptions on past climate conditions.
Species that have a greater gene pool are scientifically proven to survive better than those that have a smaller gene pool. This is because the species has diversity in the genes allowing them to be able to adapt to different situations. The smaller gene pool has less diversity meaning that it cannot adapt as easily. So, the answer is most likely D. Species A will most likely go extinct and species B will continue to thrive.
C the presence of harmful substances in food
Answer:
A. True
Explanation:
Acetyl coA is a compound which helps in the transport and availability of the acetyl group to the citric acid cycle (Krebs cycle).
Though it is not an official step in the process, Acetyl CoA formation is a transition between glycolysis and krebs, and occurs only in the presence of oxygen.
The Acetyl group helps in the oxidation for energy production.
Answer:
Light energy, Water, and Carbon Dioxide/Chlorophyll
Explanation:
Photosynthesis uses 12 water molecules, 6 Carbin Dioxide molecules and light energy so it can produce one glucose, six water and oxygen molecules. This can be expressed and represented by 12H2O + 6CO2 + light energy = C6H12O6 + 6H2O + 6O2
Vital to remember that the produced oxygen is from the original water molecules and not the carbon dioxide.
