Research on the trait perspective on leadership in groups shows that leaders are not born but develop.

<h3>What are genetic-environment trait relationships?</h3>

Genetic-environment relationships makes reference to the contribution of genetic and environmental factors to a given trait.

Complex behavioral traits such as leadership are shaped by environmental factors.

In conclusion, research on the trait perspective on leadership in groups shows that leaders are not born but develop.

Who can help me with this please

Serhud [2]

Answer:

200=x

Explanation:

In this equation,it shows 8x=1600 so you would bring the 8 under the x and leave the x and then put it under the 1600 to divide it like a fraction and get 200.I hope this helps:) Have a wonderful day!

A student does an experiment for a science fair to study whether temperature affects the timing of a cricketâ€™s chirps. The stu

nexus9112 [7]

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

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

<h2>Available data:</h2>

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

Day Temperature Average time between chirps (sec)

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

12 32 1. 1

In this experiment the student recorded the time in seconds between chirps.

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

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 the frequency of chirps increases as the temperature gets higher.

<h3>Options,</h3>

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

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.

B) The chirps occur closer together as the temperature increases.

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

C) The chirps become farther apart as the temperature increases.

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.

1. Explain how the traits of an organism are related to the genes in DNA.

viktelen [127]

Genes in DNA or responsible for the traits an organism has. This is caused by Dominant and Recessive Traits. Remember that Genotypes are the genetic letters such as RR, Rr, and rr. Phenotype is physical traits.

Dominant Traits are more likely or always show in the offspring. The Dominant Genotype uses Capital letters such as RR.

Recessive Traits are less likely to show up. Their Genotype use lower case such as rr. Now genotypes of Rr have one dominant trait and one recessive trait. If the dominant trait was black fur and the recessive white fur, the offspring will be black fur because dominant traits overpower the other.

To understand how to know if an organism will have Dominant or Recessive Genes, you have to use something called a Punnet Square. Lets imagine 2 parents both have the genotype Rr. R is Black fur and r is white fur. As you can see from the chart, 3 of 4 boxes have Rr and 1 rr. Since there is a Dominant Trait with a Recessive, they will show a Dominant Phenotype, or Black fur. This has 3/4 chance and a 1/4 chance for white fur in the offspring.
