Answer:
1) Sucrose is synthesized in the chloroplast stroma and exported from photosynthetic cells to provide energy and reduced carbon for non photosynthetic plant cells. - FALSE
2) The enzyme rubisco is unusual in that, depending on conditions, it exhibits two different enzymatic activities. - TRUE
3) Ninety percent of the solar energy collected by a photosystem complex is absorbed when photons strike a special pair of chlorophyll molecules at the reaction center of the complex. - FALSE
4) The energy requirement expressed as ATP consumed per molecule of carbon dioxide fixed is higher for a C3 plant than for a C4 plant. - FALSE
5) The ultimate electron donor for the photosynthetic generation of NADPH is always water. - FALSE
Answer: Gender identity
Explanation:
Gender identity is how a person sees themselves their own internal sense and personal experience of gender. Only the individual can determine their own gender identity. Gender indentity refers to the degree to which we see ourselves as feminine, masculine, transsexual or perhaps even nongender and having no gender at all. Gender identity occurs as a result of a combination of inherent and extrinsic or environmental factors; gender role, on the other hand, is manifested within society by observable factors such as behavior and impression
Explanation:
Fossil fuels are important energy sources for our every day activities.
Formation of fossil fuels
Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.
How are they obtained
First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.
For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.
For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.
How are they used
Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.
Natural gas is used as a domestic fuel for cooking and so also coal.
When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.

Answer:
5556
Explanation:
If a DNA polymerase synthesizes in average 50 nucleotides/second, that means that in three hours (10800 seconds) it synthesizes about 540000 nucleotides.
However, if the human genome is composed of 3000000000 (3 billion) base pairs (nucleotids), the minimum number of DNA polymerases (working in the same number of origins of replication) to finish the duplication of all the genome in three hours is 5555,5. (3000000000/540000). As we know there is no half polymerase, so we round to 5556.
5556 molecules of DNA polymerases acting on 5556 origins of replication are needed.
