Question 3 1 pts
Suppose a planet named Arcturus-e is discovered orbiting the star Arcturus. That planet has
two moons named Sat-A and Sat-B. Suppose you want to make a model of that planet/satellite
system and you have the known dimensions given in the table below.
Calculate the scale ratio and then fill out the rest of the table with values for the satellite model
diameters and model orbit distances. Show your calculations below the table (remember to show
units in your calculaticks).
Arcturus-e
10,000 km
Planet/Moon
Real diameter
Real orbital radius
Model diameter
Model orbital radius
Sat-A
1,000 km
200,000 km
Sat-B
2,000 km
100,000 km
10 cm
What is the Model orbital radius for Sat-A and Sat-B?

Efficiency is the percent of work put into a machine by the user (input work) that becomes work done by the machine (output work)

Salmonella typhimurium is a food-borne bacterial pathogen that can cause severe gastrointestinal disease. salmonella is often phagocytosed by macrophages that normally destroy bacterial pathogens, but this bacterium is somehow able to prevent the complete maturation of phagolysosomes. salmonella is able to tolerate the low ph of phagolysosomes, and in fact responds to the drop in ph by secreting toxins that interfere with other cellular responses. which of the following differences would you expect to contribute to the survival of a bacterium within an salmonella-containing phagosome, compared to a healthy phagolysosome? decreased activity of acid hydrolases increased activity of acid hydrolases decreased import of h+ ions increased import of h+ ions my guess is decreased activity of acid hydrolases but i'm not sure.

Which mechanism of transport takes place when solute particles move from a region of high concentration to a region of low concentration? active diffusion isotonic osmosis
