Answer:

The eye is an organ.

Explanation:

Organs are structures made up from different tissues, such as nervous tissue, muscle tissue, epithelial tissue and blood tissue (a type of connective tissue). These tissues, with their own specialized cells, work organizedly to make the organ function as it's supposed to do.

Rufina [12.5K]

Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time. So it could be tundra ecosystem according to the given scenario.

<h3 /><h3>What is tundra ecosystem?</h3>

Tundra ecosystems are treeless areas found in the Arctic and on mountain peaks where the climate is cold and windy and rainfall is scarce.

Much of the year, tundra lands are covered in snow, but summer brings bursts of wildflowers.

Darker colors absorb and retain warmth than warm tones. As a result, plants in the tundra have dark-colored leaves, hairy and clumped and stems to help them absorb solar heat faster and stay warm for longer periods of time.

Thus, the correct ecosystem for the given condition is tundra.

A genetically heterogeneous population of rice has a mean in the number of days to maturation of 30. Selection for decreased per
chubhunter [2.5K]

Answer:

h² = 0.6

Explanation:

Before answering the question, we need to know a few concepts.

<u>Artificial selection</u> is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.

Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.

<u>The selection differential, SD,</u> is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,  

SD = X₀ - Xs

<u>Heritability in the strict sense, h²</u>, is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.  

h² = R/SD

The <u>response to selection (R) </u>refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.  

R = h²SD  

R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),  

R = X₀ - X₁

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

Now that we know these concepts and how to calculate them, we can solve the proposed problem.

Available data:  

  • You are selecting rice´s decreased period of maturation.
  • The population of rice has a mean maturation time of 30 days → X₀
  • Parental selected average period to maturation is 25 days → Xs
  • F1 plants mature on average in 27 days → X₁
  • N arrow sense Heritability → h²

According to what we sow previously, we need to find out the value of h².

We know that h² = R/SD, so we need to get R and SD first.  

R = X₁ - X₀

R = 27 - 30

R = -3

SD = Xs -  X₀  

SD = 25 - 30

SD = -5

Knowing this, we can calculate h²

h² = R/SD

h² = -3/-5  

h² = 0.6
