190 g
4.5 x 41.99g / 1mol = 190g
B. 25% because Bb x Bb= Bb, Bb, Bb, and bb. The only one that will actually show the red feathers is the completely receive one: bb. This is only 1/4 which equals 25%
Cell biologists photograph cells in mitosis, then cut out the chromosomes from the photographs and group them together in pairs to form a karyotype.
A lot of plants in the tropical rainforest have bigger leaves to catch more water.
Answer:
b. Because they have a low affinity for the H+
Explanation:
All electrons that enter the transport chain come from NADH and FADH2 molecules that are produced in earlier phases of cellular respiration: glycolysis, pyruvate oxidation and the citric acid cycle.
NADH is very good at donating electrons in redox reactions (that is, its electrons are at a high energy level), so you can transfer your electrons directly to complex I and transform it back into NAD +. The movement of electrons through complex I in a series of redox reactions releases energy, which the complex uses to pump protons from the matrix into the intermembrane space.
FADH2 is not as good for donating electrons as NADH (that is, its electrons are at a lower energy level), so it cannot transfer its electrons to complex I. Instead, it introduces electrons to the transport chain through complex II, which does not pump protons through the membrane.
