Answer:

<em>The correct option is A)  Reproductive assurance: any individual of the same species is a potential mate.</em>

Explanation:

A hermaphrodite can be described as an organism that is capable to produce gametes associated with both the male and female sexes. It has a complete or partial reproductive organ.

In the deep sea, biodiversity is scarce. There are limited amounts of organisms present. Hence, to have a reproductive assurance, the organisms present in the deep sea are mostly hermaphrodite. Hence, they will be able to mate with any organism of the same species.

The output region is the site of ______________________.
tester [92]

Answer:

The correct answer is option C (voltage gated Na+ channels).

Explanation:

Output region or axon terminal is the structure of neuron which transmits the signals to other nerve cells.

The signal is transferred via action potential generated by the dendrite cell which moves along the axon and reaches the synaptic junction.  

At the synaptic junction, voltage-gated channel (Na+) channels located in the membrane of the axon terminal cell opens due to the changes in the electric membrane potential which play important role in returning the depolarized cell to a resting state.

Thus, option C (voltage-gated Na+ channels) is the correct answer.

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.
