Answer: CO2 levels are high in the first half of the year, low in the second half(but increasing on average over time)
SEE BELOW for the rest
Explanation:
concepts
photosynthesis uses light, CO2 and H2O to produce glucose and O2
Respiration uses glucose and O2 to produce CO2 and H2O and energy
Reasoning
this is northern hemisphere data. Winter and colder weather, and winter-deciduous trees reduce removal of CO2 from the atmosphere. The second half of the year is influenced by summer, with high growth rates and high CO2 uptake, reducing atmospheric levels
Answer:
is a process of photosynthesis
Answer:
Explanation:
Carbon Bonding
The four covalent bonding positions of the carbon atom can give rise to a wide diversity of compounds with many functions, accounting for the importance of carbon in living things.
Carbon contains four electrons in its outer shell. Therefore, it can form four covalent bonds with other atoms or molecules. The simplest organic carbon molecule is methane (CH4), in which four hydrogen atoms bind to a carbon atom.
However, structures that are more complex are made using carbon. Any of the hydrogen atoms can be replaced with another carbon atom covalent bonded to the first carbon atom. In this way, long and branching chains of carbon compounds can be made . The carbon atoms may bond with atoms of other elements, such as nitrogen, oxygen, and phosphorus . The molecules may also form rings, which themselves can link with other rings . This diversity of molecular forms accounts for the diversity of functions of the biological macro molecules and is based to a large degree on the ability of carbon to form multiple bonds with itself and other atoms.
Answer: e. choice 1 & 3
Explanation:
Plants are used for medicine and for eating, not for staying warm.
Answer:
H2O2> H2O + O2. H2O2 is the substrate. Water and oxygen are the products.
Explanation:
Catalase is important because it is an antioxidant enzyme and as such can be used against numerous oxidative stress-related diseases as a therapeutic agent.
