Answer: The relationship between culture density and toxin secretion is linear.
Explanation:
The relationship that exist between culture density and toxin secretion is linear. Cultures that are grown in high standardized density secret large amount of toxin while cultures grown at low density secret low amount of toxin.
Toxin is a poisonous substance.
A less reliable production of heat. If they choose to go solar, their house would have to have plenty on sunlight through the day, and they should not live somewhere that gets snow or is cloudy the whole day because it would block the amount of sun the house could get. They would have to plan ahead to figure out if they could use solar or not based on their home and property.
Answer:
a)Difference in physical state observed:
The difference between the two carrots is that the carrot in the plain water appears bigger or slightly swollen while the carrot in the salt water appears smaller and has shrank in length and slightly in width.
b)Process involved that has caused the changes:
The process that has taken place is osmosis.
c)Why has the process occured:
The process occurs due to the semi-permeable membrane of the cells of carrots that allow water either in or out of the cells.
In the plain water, the process that takes place is endosmosis where the cells of the carrot draw in water and hence the carrot increases in mass. The carrot in the salt water, on the other hand, experiences exosmosis, where water is drawn from the carrot's cells and the carrot becomes dehydrated and shrinks in length and width.
d) Beaker 1 : Water
Beaker 2 : Sugar Solution
e) example of endosmosis is absorption of capillary water from the soil by the root.
another example of endosmosis is is entrance of water in the xylem vessel from the soil by the root.
