During photosynthesis, light energy is converted to the energy in chemical bonds. What also happens according to the predictions
sleet_krkn [62]

<u>Answer</u>:

According to the predictions of the second law of thermodynamics "heat is released in the process".

<u>Explanation</u>:

The "second law  of thermodynamics states that total entropy of the isolated system can never be decreased over but is constant if all processes are reversible". Similarly in photosynthesis not all the energy are taken by the plants, some reflected and some are lost as well. However, the loss of energy to the surrounding results in increase of entropy. The energy used in the photosynthesis is the light. The source of this light is sunlight.

AleksAgata [21]

Answer:

The correct answer is -

1. 25%

2. 75%

3. 1:2:1

Explanation:

It is given that slimy snort S is dominant over stringy snort s which means in case, of heterozygous the slimy snort will be expressed only.

The cross between Ss and Ss will produce gametes S, sand S, s.

then,

     S    s

S   SS  Ss

s   Ss   ss

From the given punnett, it is clear that there are 1 stringy snort offspring and three slimy snort offspring will be produced which means, there is 25% likelihood of stringy snort and 75% likelihood of slimy snort.

Genotypically there are 1 dominant: 2 heterozygous : 1 recessive present.
