According to the article I've read in the website of Harvard Health Publishing (Harvard Medical School), the causes of overweight or obesity have been implicated by more than 400 different genes. Genes provide overweight in so many ways like metabolism, appetite, cravings, distribution of fats, and stress eating. Although it depends on one person to another person. Researchers have said that 25% of predisposition to be overweight is accounted to genes, while 70%-80% for genetic influences. These are just some of the reason how much of your weight depends on your genes:
-For much of your life, you have been overweight
-Overweight is seen on your parents or relatives, your likelihood to be developing obesity is as high as 80% if both of your parents are overweight

A phenotypic ratio for a dihybrid cross is predicted to be 9:3:3:1. The experimental values are:

Maslowich

Two traits that we are examining are the color (purple/white) and the smoothness.
In our sample, we have 135 individuals ( 75 +28+24+8= 135).

Since we know that expected ratio of a dihybrid cross, is <span>9:3:3:1 we can calculate what is the expected values of each phenotype is.

So, for the white wrinkled phenotype, we expect that there will be one-sixteenth of the whole sample ( there are 16 parts of the whole sample 9+3+3+1=16).
So, we multiply the whole sample- 135 with one-sixteenth (or </span>0.0625) and get 8,4375.
When you calculate the values for all phenotypes you get results shown in the attached excel table.
When you have your expected and experimental values you compare them with a chi-square test. (The test determines if the difference between the expected and experimental results is statistically significant).

a hypertonic salt solution has a higher concentration of solutes than a blood cell. explain what happens when a blood cell is pl

dem82 [27]

Answer: When a blood cells is place in Hypertonic solution, water will rush out of the cell, the cell will shrinks or crenates. This is because the solute concentration outside the cell is greater than solute concentration inside the cell.

Explanation:

Hypertonic solution is a solution that have greater or higher solute concentration outside the cell compare to the solute concentration inside the cell.

Which type of energy is provided by carbohydrate macromolecules?

aalyn [17]

Answer:

Chemical energy in the form of ATP molecules

Explanation:

The Carbohydrate molecules are the organic molecules composed of hydrogen and oxygen in the 2:1 ratio. The carbohydrate molecules are considered one of the four important biomolecules as they perform various functions in the organisms.

The simple carbohydrate molecule called glucose is the most favoured substrate which is used by the organism to provide energy. The carbohydrate molecule undergoes the process of cellular respiration to provide "chemical energy" in the form of ATP molecules. These ATP molecules are used by the cell in performing various functions.

Thus, Chemical energy in the form of ATP molecules is the correct answer.
