Explanation:

Landon glances across the dinner table and thinks to himself that his fathers curly hair looks just like his own. He wishes his hair were straight like his mothers because he thinks he looks better with straight hair. Landon works hard to keep it straighter by combing and using hair gel, but it usually curls right back up. He has his mothers nose, but not her hair, unlike his sister Emily, who is also the result of the combination of the DNA from both of his parents and has straight hair like their mothers. Most eukaryotic organisms, like Landon, are formed through the process of sexual reproduction. Landon realizes that he and Emily are evidence that sexual reproduction, the combination of their two parents, creates diverse offspring.

Landons dinner plate is filled with one of his favorite foods-mashed potatoes made from potatoes fresh from his grandmothers garden. He remembers helping her get ready to plant the potatoes in early spring. They cut each potato into several pieces and planted the pieces in a nice straight row in the garden. When these eukaryotic plants came up, he noticed that each plant looked like all the others. These identical offspring with uniform traits are the result of asexual reproduction. Landons grandmother grew potatoes by cutting the whole potato into smaller pieces, which is a type of asexual reproduction called vegetative propagation.

After dinner, Landon wanted to go watch television, but his mother insisted that he put the leftover food in the refrigerator. Perhaps she knew that the cool temperature inside the refrigerator would stop the growth of bacteria, which are prokaryotic and can reproduce asexually in as little as 20 minutes. This rapid asexual reproduction, called binary fission, would produce thousands and thousands of identical bacterial cells that could cause Landons tasty leftover food to spoil before the end of his favorite show.

Landon finishes up the dishes and puts away the leftovers. As he sets the last dinner glass back into the cupboard, he catches a glimpse of his curly hair in his reflection. He thinks to himself that his mothers nose and his fathers hair are actually a good combination that looks pretty good on him

If the same amount of heat is added to 25.0 g of each of the metals, which are all at the same initial temperature, which metal

AVprozaik [17]

Answer:

The bismuth sample.

Explanation:

The specific heat $c$ of a substance (might not be a metal) is the amount of heat required for heating a unit mass of this substance by unit temperature (e.g., $\rm 1\; ^{\circ}C$ .) The formula for specific heat is:

$\displaystyle c = \frac{Q}{m \cdot \Delta T}$ ,

where

$Q$ is the amount of heat supplied.
$m$ is the mass of the sample.
$\Delta T$ is the increase in temperature.

In this question, the value of $Q$ (amount of heat supplied to the metal) and $m$ (mass of the metal sample) are the same for all four metals. To find $\Delta T$ (change in temperature,) rearrange the equation:

$\displaystyle c \cdot \Delta T = \frac{Q}{m}$ ,

$\displaystyle \Delta T = \frac{Q}{c \cdot m}$ .

In other words, the change in temperature of the sample, $\Delta T$ can be expressed as a fraction. Additionally, the specific heat of sample, $c$ , is in the denominator of that fraction. Hence, the value of the fraction would be the largest for sample with the smallest specific heat.

Make sure that all the specific heat values are in the same unit. Find the one with the smallest specific heat: bismuth ( $\rm 0.123 \; J \cdot g\cdot \,^{\circ}C^{-1}$ .) That sample would have the greatest increase in temperature. Since all six samples started at the same temperature, the bismuth sample would also have the highest final temperature.
