Yes they can Only eukaryotes form multicellular organisms consisting of many kinds of tissue made up of different cell types
The answer is c. Electron transport chain
Answer:
Diatoms
Explanation:
Diatoms are a photosynthetic eukaryotic phytoplankton that virtually found in all waterways, fresh waters and oceans, and also in most soils on earth. Diatoms play a very important role in the global carbon cycle. Diatoms are single-celled algae that has a characteristics cell wall that is made up of transparent opaline silicia that are elegantly sculpted.
When diatoms die, their shell or skeleton that is composed of silica, do not decay, but settle at the bottom of oceans as sediments to form what is often referred to as diatomaceous earth. It is this diatomaceous earth deposit that is then converted to diatomite powder, which is used as pesticides against insects such as ants, cockroaches, bedbugs and some other pests.
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
