Skin prevents the body from getting infections
Answer:
Membrane proteins perform a variety of functions vital to the survival of organisms: Membrane receptor proteins relay signals between the cell's internal and external environments. Transport proteins move molecules and ions across the membrane.
Explanation:
they help transport some substances through the membrane.
None of the provided options are reasonable. <span>comparing nutrient concentrations between the photic zone and the benthic zone can not tell you whether differences in concentrations between the photic and benthic zone are due to uptake by phytoplankton or because nutrients are sinking to the sea bottom and ocean stratification is preventing mixing. The approach of c</span><span>ontrasting nutrient uptake by autotrophs at different locations under different temperatures would not provide useful information on limiting nutrients. but rather uptake rates at different temperatures. It is likely that e</span>xperimentally enriching some areas of the ocean and compare their productivity to that of untreated areas can provide an indication of limiting nutrients, but this is not advisable, as it would have to be done on a large scale, and one cannot be sure of the ecological consequences. Also, because it would not be a controlled experiment, other factors could create 'noise' in the data. The last option, <span>observe antarctic ocean productivity from year to year to see if it changes, also does not help, as there is no correlation between nutrient concentrations using this approach. The best approaches would be either the last approach, but with the additional monitoring of nutrient concentrations, or under a controlled laboratory experiment.</span>
Epithelial tissues are the tissues that lines inside of hollow organs. <span> Epithelial tissues covers body surfaces; lines the body cavities and hollow organs.</span>
Answer:
See the answer below
Explanation:
<em>When the salt water resulting from using salt to thaw ice and snow is washed off the road, the nearby plants along the roadside would be subjected to osmotic stress due to the lower water potential of the soil water when compared to that of their cells. Consequently, the plants are expected to lose water to the surrounding salt solution until an equilibrium is established between their cytosols and the soil solution. </em>
