Some people have their gall bladder surgically removed to the formation of gall stones. Describe the function of the gall bladde

sertanlavr [38]

Underneath the right side of the liver, the gallbladder is a pear-shaped organ.

<h3>What is the function of gall bladder?</h3>

Its primary function is to gather and concentrate bile, a digestive fluid made by the liver. The gallbladder is where bile is kept after the liver produces it. The gallbladder receives a signal from the stomach when you eat. Bile is released from the gallbladder when it contracts, and it travels through the gut via the major common duct. Bile combines with the food there and aids in digestion.

When the gallbladder is removed from a healthy person, there are rarely any obvious health or digestive issues, though there is a slight chance of diarrhea and fat malabsorption.

What impact does deforestation have on the carbon cycle?

Vlad [161]

Answer:

Deforestation can affect the water cycle and the carbon cycle. It will decrease the amount of transpiration. It will also increase the amount of carbon dioxide in the atmosphere by releasing the carbon dioxide as trees are burned and by decreasing photosynthesis.

22. A plant geneticist is investigating the inheritance of genes for bitter taste (Su) and explosive rind (e) in watermelon (Cit

mylen [45]

Answer:

See the answer below

Explanation:

Using the formula for calculating Chi square ( $X^2$ ):

$X^2$ = $\frac{(O - E)^2}{E}$ where O = observed frequency and E = expected frequency.

The observed frequencies for the four phenotypes are 88, 62, 62, and 81 respectively.

For the expected frequency, the phenotypes are supposed to assort in 9:3:3:1 according to Mendel ratio.

Hence, expected frequencies are calculated as:

phenotype (1) = 9/16 x 293 = 164.81

phenotype (2) = 3/16 x 293 = 54.94

phenotype (3) = 3/16 x 293 = 54.94

phenotype (4) = 1/16 x 293 = 18.31

The $X^2$ is calculated thus:

Phenotype O E $X^2$

1 88 164.81 $\frac{(88 - 164.81)^2}{164.81}$ = 35.80

2 62 54.94 $\frac{(62 - 54.94)^2}{54.94}$ = 0.91

3 62 54.94 $\frac{(62 - 54.94)^2}{54.94}$ = 0.91

4 81 18.31 $\frac{(81 - 18.31)^2}{18.31}$ = 214.64

Total $X^2$ = 35.80 + 0.91 + 0.91 + 214.64 = 252.26

To the nearest tenth = 252

Degree of freedom = n - 1 = 4- 1 = 3

$X^2$ tabulated = 7.815

<em>The calculated </em> $X^2$ <em> exceeds the critical value, hence, the null hypothesis is rejected. The two genes did not assort independently. </em>

Explain two ways that mountain climbing and rock climbing are different?

babymother [125]

Please, please pick me as brainiest. It would make my day!

Answer:

The best way to look at it is that mountain climbing is a sport that involves the scaling of a mountain in its entirety. ... However, rock climbing by itself is so extensive that it can be and often is its own sport. Some mountains are more easily traversed by hiking, such as Mount Baker.
