The answer is biological species concept. This is because each different finch evolved isolated from one another, which means that they can no longer interbreed.

mrs_skeptik [129]

Answer:

The correct answer is option C.

Explanation:

As it is given that, a Mendelian cross is performed between two parents resulted by cross the parents. This suggests that the parents or P generation has zero recombination hence the genotype of Parents would be AA and aa in nature. Therefore, all the F1 generation offspring were Aa in nature. The selfing of the F1 offspring will be:

         A  a

A AA Aa

a Aa aa

Genotype: AA: Aa: aa :: 1:2:1

Phenotype: Dominant: recessive :: 3:1

A student does an experiment for a science fair to study whether temperature affects the timing of a cricket’s chirps. The stu
nexus9112 [7]

The frequency of chirps increases as the temperature increases. The correct option is B. <em>The chirps occur closer together as the temperature increases.  </em>

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

<h2><u>Available data:</u></h2>

<h3>Data recorded by the student </h3>

<em><u>Day      Temperature   Average time between chirps (sec)</u></em>

1            21                             2. 5

2           22                            2. 6

3           23                            2. 2

4           24                            2. 3

5           25                            2. 0

6           26                             1. 8

7           27                              1. 9

8           28                             1. 8

9          29                             1. 4

10          30                             1. 2

11           31                              1. 5

<u>12          32                             1. 1</u>

In this experiment the student recorded the time in seconds <u>between </u><u>chirps</u>.

We can see that <em>as the </em><em>temperature increases</em><em>, in general, the</em><em> time</em><em> between</em><em> chirps decreases</em>.

  • At 21ºC the time between chirps is 2.5 seconds
  • At 26ºC the time between chirps is 1.8 seconds
  • At 32ºC the time between chirps is 1.1 seconds

According to this information, if the average time between chirps decreases with the temperature increase, we can assume that<em> the </em><em>frequency</em><em> of chirps </em><em>increases</em><em> as the temperature gets higher. </em>

<h3>Options,</h3>

<em>A) The higher the temperature, the fewer chirps there will be in 10 seconds</em>.

Wrong. The number of chirps in 10 seconds will depend, not only on the frequency but also on how long the chirps last. Since the student did not record the time of chirps, we can not make this conclusion.  

<em>B) The chirps occur closer together as the temperature increases</em>.

True. The chirps increase in frequency as the temperature increases, so they occur closer together.

<em>C) The chirps become farther apart as the temperature increases</em>.

Wrong. We can see how the time between chirps decreases as temperature increases, meaning that they are closer not farther.

D) There is no relationship between temperature and the time between chirps.

Wrong. If we make a graph we will see the tendency and the relationship between chirps and temperature.

Graphs usually explain the relationship between variables. In this example, the relationship would be inverse.

Photosynthesis is the term for the process by which plants produce food and energy in the presence of some inorganic substances and solar energy.

<h3>What is the reason behind the above answer ?</h3>

The glass of water won't react when it's placed in the sun's rays.

One explanation for the response is: Water and ambient carbon will be the reactants in the experiment, which should produce glucose and oxygen in the presence of the sunbeam.

The true photosynthetic reaction also uses carbon dioxide and water as reactants, but chlorophyll is a plant pigment that is present during the reaction.
