Answer:  6CO2 + 6H20 + (sunlight energy) → C6H12O6 + 6O2

Explanation:

Photosynthesis is a process that transforms the energy of sunlight into chemical energy. It basically consists in the <u>elaboration of sugars from C02 (carbon dioxide ) minerals and water with the help of sunlight</u>. So it is the process of food production by plants. Trees and plants use photosynthesis to feed themselves, grow and develop.

To carry out photosynthesis, plants need chlorophyll, which is a green substance that they have in their leaves. It is in charge of absorbing the appropriate light to carry out this process. In turn, chlorophyll is responsible for the characteristic green color of plants.

Photosynthesis takes place in plant cell membranes. There, <u>photons, the particles that make up sunlight, break up the water molecules acquired by plants by releasing electrons and protons,</u> other particles that in turn cause reactions that produce ATP and NADPH2 (two molecules that serve to store energy). Then, with the carbon dioxide that plants absorb from the atmosphere, they form carbohydrates in which energy is store

So, through photosynthesis, organisms with chlorophyll take in atmospheric <u>CO2 or dissolved in water to form more complex molecules</u>, such as carbohydrates, lipids, proteins and nucleic acids. But during photosynthsis, glucose (C6H12O6) is produced. The function of <u>water in photosynthesis is to supply electrons for these redox reactions</u>, i.e. water acts as a source of electrons. Since the water molecule is a very weak reducing agent, its electrons must be energized by the photons of sunlight. The <u>oxygen released in photosynthesis comes from water and it is a waste product which eventually will be used by other living organisms to breath.</u>

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>

Landscape in which limestone is eroded to form deep valleys and caverns
irina [24]
The landscape in which limestone is eroded to form deep valleys and cavers are called Karst landscape or karst topography. This kind of development start occuring whenever the acidic water starts breaking down the bedrocks near the cracks. As the bedrock starts breaking down slowly, the cracks start to open up creating bigger holes. with passage of time the holes will become big enough to create an underground drainage system for the surface water to flow and form underneath. If the water is unable to flow out and becomes stagnant, then the Karst will start getting bigger.

Viscous fiber helps to lower blood cholesterol levels by interfering with the reabsorption of ________ in the intestines.
Yuki888 [10]
By interfering with the absorption of BILE in the intestine. Bile contains cholesterol, if it absorbed from the intestines it will increase the level of cholesterol in the blood stream. So, the viscous fiber stop this by sequestering the bile acids.
