Look up your test statistic on the appropriate distribution- in case, on the standard normal (Z-) distribution ( see the following Z- table)
The villi can increase the surface area in the small intestine for absorption of digested food. As the villi has a thin wall, one cell thick, which can speed up diffusion, and a network of blood capillaries to absorb and transfer nutrients.
And in large intestine, those folds can also increase the surface area for reabsorption of unabsorbed food, mostly water.
Answer:
Predictions provide a reference point for the scientist. If predictions are confirmed, the scientist has supported the hypothesis. If the predictions are not supported, the hypothesis is falsified. Either way, the scientist has increased knowledge of the process being studied.
Answer:
first step - take one-fourth of the field and cout the sunflowers in it
second step - find out the percentage and that will be you answer
<span>Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion.
The absorption spectrum of chlorophyll a alone underestimates the effectiveness of certain wavelengths in driving photosynthesis. This is partly because accessory pigments with different absorption spectra are also photosynthetically important in chloroplasts and broaden the spectrum of colors that can be used for photosynthesis.</span>
