The rate at which blood flows through the human body changes in response to many factors. which statement describes one of these factors and its effect on blood flow?
a. a high viscosity of blood causes an increased resistance in the blood vessels and leads to slow blood flow.
b. a low blood ph decreases the rate of diffusion through the blood vessels and leads to slow blood flow.
c. the changing of the shape of red blood cells to a crescent shape decreases resistance and lead to a faster blood flow.
d. the narrowing of blood vessels increases pressure and leads to a faster blood flow.

Interpret the model. a three-part model with black right-arrows between the parts. left part: a large green apple-shaped component with a w-shaped indentation centered on top. a small blue apple-slice shape sits above the left indentation and an arrow points from the shape to the indentation. a small purple apple-slice shape and arrow sit above the right indentation and an arrow points from the shape to the indentation. middle part: a large green apple-shaped component with a square indentation centered on top. sitting in the left side of the indentation is a blue apple-slice shape with a flat bottom, fused to a purple apple-slice shape with a flat bottom on the right side of the indentation. right part: a large green apple-shaped component with a w-shaped indentation centered on top. an up-arrow is centered above the indentation pointing to a fused blue and purple apple-slice-shaped flat-bottom component sitting above the indentation. assigne "true" or "false" to the end of each statement. the model shows a shape change occurring in the enzyme after the substrate is bound in the active site. t/fthere are two products in this model. t? f there are three substrates in this model. t/f the model shows two different enzymes. t/f

Sediment layers stop lateral spreading when: they encounter a barrier they encounter an opposing current they run out of additional sedimentary material
