Trick question. Bacteria do not have cell walls. They barely have cell membranes. The second blank might be either chemosynthetic (break down chemicals for food) or photosynthetic (generate food from sunlight).

What can you do to ensure that you will continue to be motivated for the duration of your fitness program?
avanturin [10]
1. Make a goal for yourself. When you finish your fitness program(achieve your goal) you can reward yourself with like icecream or a small treat.

2. Make working out fun so that you will keep wanting to do it. For example, work-out or go to the fitness program with a friend, listen to music while doing it, etc.

3. You can make yourself motivated by watching fitness videos and basically watching things to get inspiration(trust me this works).After you watch the vids, your gonna want to keep going to the fitness program cause of all the benefits and things like that. 

4. Ask a friend or someone to push you to keep going(if all else fails and you wanna quit) They will annoy you so much that it would just be better to go to the fitness program than hear them annoy you.

5. Think why your going to regret not going. This is gonna make you want to go to the fitness program.

6. Honestly if the others don't work, do it for the pictures and so that you can brag to people that you work out and stuff.

That's all I got for now. Hope it helped motivate you to keep going to that fitness program <span />

Which is a mechanism for restricting the movement of proteins in the plasma membrane? Choose one or more:
alexgriva [62]

Answer:

The correct answers are option A. "tethering proteins to the cell cortex", B. "using barriers such as tight junctions", C. "tethering proteins to the extracellular matrix", D. "forming a covalent linkage with membrane lipids", E. "tethering proteins to the surface of another cell"

Explanation:

According to the fluid-mosaic model, the components of cell membranes are in constant movement forming a barrier to avoid unwanted exterior component internalization and to avoid the loss of precious internal components. This constant movement could cause that proteins move across the plasma membrane. But, this is avoided by several mechanisms including:

A. Tethering proteins to the cell cortex. The cell cortex is a rigid structure made of actin and actomyosin. Proteins found in the plasma membrane are tethered to this structure to restrict their movement.

B. Using barriers such as tight junctions. Tight junctions are barriers found in epithelia made of claudin and occludin proteins. These barriers are impenetrable, which avoid the movement of proteins in the cell membrane.

C. Tethering proteins to the extracellular matrix. The extracellular matrix is made of several proteins and macromolecules that provide a structural and biochemical support to cells that are nearby. Proteins could be tethered to this rigid structure as well.

D. Forming a covalent linkage with membrane lipids. The proteins in the cell membrane that form a covalent linkage with membrane lipids are known as lipid-anchored proteins, or lipid-linked proteins.

E. Tethering proteins to the surface of another cell. When cell-cell communication take place it is possible that proteins in the cell membrane got tethered to the surface of the other cell.
