Why does my boyfriend feel the need to control me??
I have been living with my boyfriend for 5 yrs now…he makes more money then me…he makes 20 dollars an hour..and i make 9;50 an hour..right now i am only getting 34 hours a week because we are in the slow season…i give him 60 a week towards bills…i pay my own cell bill…my own car insurance and what ever else my car needs…plus i buy the food for the house
i also bring him food home from the resturant that i work at..anything from spag to prime rib…i even make him a sandwitch so he can take it to work with him…no matter what i do it seems not good enough…he likes to say that i am working againts him….is this a controlling situation?…or is he right to hurt me like this?
Need help on Biology homework about “Exchange of materials in and out of the cell”?
Please help me on my Biology homework, I have so many things to do tonight.
Science Investigations
A. Questions
1. When you add sugar or salt to freshly peeled bananas or potatoes, they become soft and watery. Why do you think this happens?
2. How does salt preserve food?
B. Problems
1. If red blood cells are placed in a salt solution, what do you think will happen to the cells?
2. Why is it easier to dissolve sugar in hot water than in cold water?
C. Research
Design an experiment tat will show cellular respiration in germinating seeds. (what should I put here?)
Take note to relate your answers to the exchange of materials in and out of the cell.
Thanks in advance.
