Iodine is a yellowish solution. A starch solution is white. A starch solution turns purplish-black in the presence of iodine. If

you wait a few hours, then add iodine to the beaker, what color would the beaker solution be?

Answer:

The correct answer will be- the color change will be observed and the solution will turn purplish-black.

Explanation:

Iodine test is performed to test the presence of the carbohydrates mainly starch.

The iodine solution is chemically called potassium iodide which forms a yellow solution. The potassium iodide solution forms a complex with a starch solution which appears a purplish-black color which shows the presence of the carbohydrates.

In the given question, if we add the iodine solution to the beaker after a certain point of time then it will still form a complex with the starch and thus beaker solution will appear darker in color.

The flow of air caused by ____ and the Coriolis effect creates distinct wind patterns on Earth's surface. a. differences in heat
kakasveta [241]
<h3><u>Answer;</u></h3>

Differences in heating

The flow of air caused by <u>differences in heating </u>and the Coriolis effect creates distinct wind patterns on Earth's surface.

<h3><u>Explanation</u>;</h3>
  • <u>Movement of air or flow of air is caused by pressure or temperature differences and is experienced as wind.</u> When there is a pressure difference between two places, a pressure gradient exists, across which air moves from the region of high pressure to the region of low pressure.
  • <em><u>Differences in temperature also causes movement of air or wind know as convection. The air flow caused by temperature difference is observed in the case of sea and land breezes, because of the difference in temperature between the sea and the land.</u></em>

1. The effect of initial population sizes on the growth of populations of an organism was
ella [17]

When graphing data, we must consider the variables, label axes, define units of measure. In this case, variables are initial population size / final population size, showing an directly proportional relationship.

-------------------------------------

We need to construct a graph illustrating the data in the table.

We can make a <u>dispersion graph</u>. To do it, we need to define variables.

Since we want to know how <em>different initial population sizes affect population growth, </em>

  • the independent variable is the initial population size
  • the dependent variable is the final population size (after 24 hours)

The final population size depends on the initial population size. This is, <em>the number of individuals at the beginning will </em><em>influence</em><em> the final number of individuals</em>.

  • Initial population sizes ⇒X horizontal ax ⇒Unit: Number of individuals
  • Final population sizes ⇒ Y vertical ax ⇒ Unit: Number of individuals

By making a dispersion graph, we can represent the effect of the varying initial population sizes on the final population sizes. We can compare these effects and observe how populations grow as the N₀ increases.

We can also choose a <u>bar graph</u>. In this way, we can compare initial and final population sizes.

This graph will show populations and two bars per population.

  • Blue bar ⇒N₀⇒ Initial population size
  • Red bar ⇒N₁ ⇒ Final population size
  • Different populations ⇒ 1, 2, 3, 4, 5 ⇒ Represented in the X horizontal ax
  • The number of individuals ⇒ from 1 to 324 ⇒ Represented in the Y vertical ax.

By making a bar graph, we can represent initial and final population sizes and compare them. <em>The population that begins with 1 individual, after 24 hours has 4 individuals. The population that begins with 3 individuals, ends with 9 individuals. And so on</em>.

No matter which graph you choose, you will observe a directly proportional relationship between both variables. The bigger is the initial population size, the bigger it ends after 24 hs.
