McBossatronio,
The answer is the first option "all systems work together to stabilize the body." Homeostasis is the internal conditions that all living things have basically meaning how the body keeps cool during hot weather, or warm during cold weather. You ever wonder why you sweat when it's hot, or shiver when it's cold that's your body keeping warm and cool which helps all your systems work together.
Hope this helps!

Answer:
Proteins and lipids exist as separate but loosely attached molecules that can move around
Explanation:
Cell membranes are mainly composed of lipids, proteins, and also carbohydrates. Phospholipids are the most abundant type of lipid and the main constituent of the cell membranes. Membrane proteins are divided into two types according to their interactions with the cell membrane: 1-integral (intrinsic) and peripheral (extrinsic) proteins. These peripheral proteins are loosely attached by ionic bonds or calcium bridges with the phosphate heads of the phospholipids; whereas integral membrane proteins contain side chains that interact with fatty acyl groups of the phospholipids. Cell membrane fluidity indicates how easily lipids (e.g., phospholipids and cholesterol) and proteins (e.g., intrinsic proteins) diffuse laterally in the cell membrane. This fluidity is affected by the amount of cholesterol, temperature, and the ratio of unsaturated to saturated fatty acids. Saturated fatty acids have no double bonds in the hydrocarbon chain, whereas unsaturated fatty acids have at least one double bond (these double bonds increase fluidity). Moreover, higher temperatures increase membrane fluidity, whereas cholesterol molecules function to regulate membrane fluidity: at high temperatures cholesterol molecules stabilize the membrane, whereas at low temperatures intercalate between phospholipids, thereby preventing them from clustering together.
Answer:
Explanation:
The total solution formed after mixing the components will be
20 μl + 20 μl + 40 μl + 120 μl = 200 μl
The smallest size tube that will hold the entire reaction is:
Firstly convert 200μl to ml
1000 μl = 1 ml
200 μl = X
X = 200 x 1/1000
X = 0.2 ml
The smallest size tube (from the options provided in the question) is 0.25 ml.
The pipetting device that could be used to accurately measure all the needed volumes must be able to measure 20 μl, 40 μl and 120 μl.
The best pipette to accurately take these measurements individually is the P200 micropipette because it has an accurate/useful range of between 20 μl - 200 μl
