Scientists are testing substance L to determine how it enters mammalian cells in a culture. The cells maintain a 120 millimolar (mM) intracellular concentration of substance L. The scientists determined the rate of entry of substance L into the cells at various external concentrations of substance L (10 to 100 mM) in culture medium (Table 1). Table 1. Rate of entry of substance L into mammalian cells in culture
External concentration of substance L (mM) Rate of entry of substance L into cell as a percent of maximum
10 5%
20 25%
30 45%
40 65%
50 80%
60 90%
70 95%
80 100%
90 100%
100 100%
The cells maintain substance L at an internal concentration of 120 mM.
Determine the external concentration of substance L that will result in one-half of the maximal entry rate.

answer; /// i really don't understand your question/statement.but/lions do fight over territory and breeding rights, sometimes to the death,this is called( i hope this answered your luck

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
