Which feature of the kinetics of L-Alanine transport would provide evidence that DOM is an important source of nutrients under low-food conditions?

High affinity transport (Kt) of L-Alanine

-Under low food conditions, the capacity of transport is irrelevant as no transporters are saturated with L-alanine

-However, the transporter's affinity for L-alanine would be important as only HIGH AFFINITY transporters will be able to facilitate L-alanine uptake at low concentrations

Which organisms have pharyngeal arches that develop from all three germ layers and go through the same development stages as embryos? 1.bird 2.ladybug 3.starfish 4.snake

Diffusion and osmosis are forms of passive transport

Which of the following best describes the expensive tissue hypothesis? brains require more energy, so the gut had to be reduced, and larger brains and tool use led to higher quality diets. increasing body size means that homo neanderthalensis had to include more fat in its diet. brains require more energy, so the gut had to be reduced as brains got bigger. brains require more fat, so the gastrointestinal viscera (gut) had to expand, and hands were needed to acquire more food.
