Answer: Container P.
Explanation: All of the containers started at 30 degrees, and they all lost heat, as shown in the table. However, Container P saw the smallest decrease in temperature. This means that Container P was most effective at preventing heat transfer from the water to the environment.
<span>Australopithecines have been found in both the Southern and Eastern parts of Africa. These areas exhibit unique geological conditions that have allowed fossils to be preserved for millions of years. These regions are South Africa in the Limestone caves and in Eastern Africa the sedimentary basins and the river drainage systems.</span>
Answer:
It can be determined by measuring product appearance or reagent disappearance also enzymatic activity (described below
)
Explanation:
Effect of pH on enzymatic activity
PH effect: affects the state of dissociation of the groups, although all proteins are not affected in the same way because some do not have dissociable groups. Most enzymes have an optimal pH. If there are small changes in pH, the enzyme is not denatured. The pH can affect in two ways:
The substrate binding is better or worse than before.
That affects the catalytic speed of the reaction.
The enzymatic speed is measured in M / t and the enzymatic activity in mol / t, and the international unit μmol / min, amount of enzyme that transforms a micromol from substrate into product in one minute under optimal conditions. Another unit is the enzymatic amount that is required to transform 1 mol / s and is called katal.
Answer:
14 cm
Explanation:
Oh, this is a trick question! The thing is, the plant was <u>already 4 cm </u><u>on Day 0</u>. So from Day 0 - Day 15, the plant actually only grew (18 - 4 =) 14 cm.
They got you this time, but hopefully you know to watch out next time. I hope this helps!
Answer:
Osmosis
Explanation:
Water moves across cell membranes by diffusion, in a process known as osmosis.
