Answer:
C. Active transport
Explanation:
Active transport is the process by which cells introduce substances against their osmotic potential. It is the opposite of diffusion, where substances move through membranes without the need of extra energy, as they follow a favorable osmotic potential towards equilibrium.
Active transport needs special proteins on the membranes to perform the task, whereas diffusion may need them (facilitated diffusion) or not (osmosis) depending on the size of the incoming molecules and the membrane's permeability.
The electron transport chain and ATP synthase are embedded in the inner mitochondrial membrane.The electrons flow through the electron transport chain, causing protons to be pumped from the matrix to the intermembrane space. Eventually, the electrons are passed to oxygen, which combines with protons to form water.
when a homozygous white rabbit (bb) is crossed with a heterozygous black rabbit (Bb). what proportion of white rabbits would the offspring have?
Answer:
Based on the Mendelian fashion cross,
bb is hetezygote reccessive.(white)
Bb is heterozyote dominant.(black)
Therefore,the the cross to show the proportion is below
Bb,Bb,bb,bb,
2 blacks(hetero zygote blacks) and 2 white.(homo zygote whites)
thus 2 of the offspring will be white, in 50%, of the number of offspring
Explanation:
Answer:
cancer results not from a single flawed gene, but rather the interplay of multiple genes and any accumulated damage to DNA caused by environmental factors such as exposure to chemicals, or aspects of lifestyle, such as smoking
Answer:Light Absorption by PSI Excites Electrons and Facilitates Electron Transfer to an Electron Acceptor Outside the Thylakoid Membrane. PSI is another large protein-pigment complex that contains lightabsorbing antenna molecules and a reaction center.
