Explain how the substitution affect in the income effect interact with changes in price to change the quantity demanded

kolbaska11 [484]

Answer:

For normal goods, the income effect and the substitution effect both work in the same direction; a decrease in the relative price of the good will increase quantity demanded both because the good is now cheaper than substitute goods, and because the lower price means that consumers have a greater total purchasing power.

Over time, three types of cells derived from this single-celled animal have emerged with specialized functions and they interact

Deffense [45]

Answer:

Golgi bodies, endoplasmic reticulum and lysosomes.

Explanation:

Many vesicles are formed in the Golgi bodies and the endoplasmic reticulum, that is responsible for the transportation of materials from one part of the cell to another. Endoplasmic reticulum is the organelle that launches the toxin-loaded vesicles or in other words it is responsible for detoxification i. e. removal of toxic substances from the cell. Lysosomes is the organelle that act against the microorganisms such as bacteria , virus etc.

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.

Artificial selection 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.

The selection differential, SD, 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

Heritability in the strict sense, h², 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 response to selection (R) 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

Besides oxygen, what other bloodborne material must be provided to the affected tissues in adequate quantities to promote normal

victus00 [196]

Healing wounds, especially full-thickness wounds, require an adequate supply of nutrients. Wounds require calories, fats, proteins, vitamins and minerals, and adequate fluid intake. Calories provide energy for all cellular activity, and when in short supply in the diet, the body will utilize stored fat and protein.Sufficient dietary calories maintain padding and ensure that dietary protein and fats are available for use in wound healing. In addition, adequate levels of protein are necessary for repair and replacement of tissue. Increased protein intake is particularly important for wounds where there is significant tissue loss requiring the production of large amounts of connective tissue.
