State one reason why the concentration of glucose in the blood decreases. What are the four toxic forms of oxygen? Explain why they are dangerous to cells. What is the method for the reduction of oxygen in Enterobacteriaceae? How are inhalation and exhalation carried out?
Why do living cells need carbon? Under what circumstances might it be advantageous for a bacterial cell to have a capsule rather than a slime layer? Explain why the cell is said to be the basic unit of life. Describe Apoptosis and...
When people have sickle cell anemia, they cannot efficiently transport oxygen. What are the implications at the cellular level (hint: why do cells need oxygen)? Describe how this deprivation of oxygen might make these patients feel. Why doesn't a blood tr ...
Why are fuel cells taking so long to catch on? Find out moreWhat are fuel cells?There are really just two ways to power a modern car. Most cars on the road today use an internal-combustion engine to burn petroleum-based fuel, generate heat, and push pistons up and down to drive the...
which led to male catkins being more sensitive to GA signals at earlier fluorescence times. In this scenario, male catkins would need less GA to stimulate the development of the stamen. Additionally, the dimorphism of gene expression might partially explain why the rachis of male catkins was ...
—Scientists are mapping Earth's rivers from space before climate change devastates our planet —Why is Earth's weather getting weirder? —Should we seal DNA samples of Earth's endangered species in a moon crater? Given the criticism often leveled at space programs worldwide that they are exp...

OTEC can also be used to produce fuels such as hydrogen; the electricity it generates can be used to power an electrolysis plant that would split seawater into hydrogen and oxygen, which could be bottled or piped ashore and then used to power such things as fuel cells in electric cars. ...
We can instead express this result in terms of the maximum cell concentration within the aerosol substrate by considering the number density of cells in the cloud layer and the aerosol mass loading of the Venusian lower-cloud droplets (see the Methods section for details). For our maximum biomas...
Why does blood flow through the cardiovascular system? a. Because the heart establishes a pressure gradient. b. Because cells need blood to survive. c. So that oxygen and nutrients can get to all parts of the body. d. Because without blood flo...
