Answer:

Ratio used to describe a change that represents relationship between two values numerically.

Therefore, the correct answer to the question is option A.

Explanation:

Ratio is a relation between two numbers. This relationship is represented numerically. The relationship is not represented graphically or by a picture manner. Also, it is not the relationship which is represented on a scale.

Hence ratio is relationship which is represented numerically. The ratio is defined as a part of something in the whole. By ratio we can also calculate the parts whichever is needed.

Photosynthetic and chemosynthetic organisms can be called primary producers because they make their own food?
LenaWriter [7]

Heterotrophs are organisms that must consume food from other organisms because they are unable to synthesize their own food molecules.

<h3>What is heterotrophs?</h3>
  • An organism is referred to be a heterotroph if it is unable to manufacture food on its own and must obtain it from other sources of organic carbon, primarily plant or animal materials.
  • Heterotrophs are primary, secondary, and tertiary consumers in the food chain but not producers.
  • Because they eat producers or other consumers, heterotrophs are referred to as consumers.
  • Humans, dogs, and birds are all instances of heterotrophs.
  • In a food chain, a group of creatures that supply energy and nutrients to other organisms, heterotrophs occupy the second and third levels.
  • An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy.
  • Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition."
  • Autotrophs and heterotrophs are two main classifications of organisms depending on how they receive energy and nutrients.

You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A s
inn [45]

Answer: 1. S = 0.77

              2. R = 0.14

Explanation:

1. <u><em>Selection</em></u> <u><em>differential</em></u> is the difference between the population mean and the average of the selected parents. Its symbol is S.

S = mean of selected parents - population mean

S = 6.48 - 5.71

S = 0.77

2. <em><u>Response</u></em> <em><u>to</u></em> <em><u>Selection</u></em> is how much gain you make when crossing over selected parents. Its symbol is R.

R = mean of offspring of selected parents - population mean

R = 5.85 - 5.71

R = 0.14

3. <em><u>Heritability</u></em> is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².

To calculate it, use Breeder's Equation:

R = h²S

h^{2}=\frac{R}{S}

h^{2}=\frac{0.14}{0.77}

h² = 0.18

4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.
