*Given Percent of the wolves which are female - 55% Percent of the wolves which hunt in medium-sized packs - 20% Percent of the wolves which are both female and hunt in medium-sized packs - 15%
*Solution
<u>Assuming that there is a total of one hundred wolves in the species, </u>
1. Since percent (%) means "per 100" or "for every 100" then,
2. Because there is a total of 55 female wolves in the species, and 15 of these wolves hunt in medium-sized packs, then the number of female wolves that do not hunt in medium-sized packs is,
55 female wolves total - 15 female wolves hunting = 40 female wolves not in medium-sized packs hunting in medium sized packs
3. To find the proportion, we can express the answer in terms of percent (%) or in fraction, which is usually how proportions are expressed.
For every 100 wolves, there are 40 female wolves that do not hunt in medium-sized packs. This can be expressed as a proportion of
<span> <u> 40 </u> </span> 100
and simplified by dividing both the numerator and denominator by 10, we get,
<span><u> 40/10 </u> </span> 100/10
<span><u> 4 </u> </span> 10
When this is expressed in percent, we multiply the fraction or proportion by 100% to get,
<span><u> 4 </u> x 100% = 40% </span> 10
Thus, the proportion of female wolves that do not hunt in medium sized packs is 4/10 or 0.4. When expressed as percent, this is 40%.
No, in facilitated diffusion molecules move against their concentration gradient. Facilitated diffusion is diffusion that requires an input on energy; moving against the concentration would require that energy.
Dog is more closely related to a red fox than a house cat according to a taxonomy level.
<u>Explanation:</u>
Dog, red fox, house cat is in the same kingdom Animalia, same phylum Chordata, same class Mammalia, same order Carnivora but the family of red fox and the gad is same i.e. Canidae but the family of the house cat is Felidae.
The red fox and dog have more taxon in common. The house cat diverges at the family level.
The major difference is that plants use vacuoles to store excess amounts of water, while animal cells do not. A plant standing up straight compared to a plant wilting over is a result of water capacity in the vacuoles
The energy stored in ATP at one location is released from ATP when the terminal phosphate bond is broken. In this process a phosphate group is detached to yield inorganic phosphate and ADP and results in the liberation of 7.3 kcal/mol (under standard conditions).
