Answer:
The recombinant frequency between T and S is 18%;
The correct Sequence of genes is T-A-S
Explanation:
The table below shows the recombinant frequency between heterozygous height and nose morphology:
Tall-uptrend snout 40% Expected
Dwarf-downtrend snout 42% Expected
Dwarf-uptrend snout 9% Recombinant
Tall-uptrend snout 9% Recombinant
Sum Total 100%
To calculate the recombinant frequency; we have :
=9+9
=18%
Hence, the recombinant frequency between T and S = 18%
The determinant of the corect sequence of the genes is T-A-S
Purple white and lavendar four oclock flowers why did the four o'clock flower plant give three phenotypes instead 2 is a genotype that is 2:2 Rr and rr.
The 4'o clock plant, phenotypes , exhibits partial dominance in flower colour, which is why the F1 plant produced by crossing a pure Red flowered plant (RR) with a pure White flowered plant (rr) has pink flowers (Rr).When an F1 plant (Rr) crosses with a pure white flowering plant (rr), the resulting plant will have a genotype that is 2:2 Rr and rr.
The phenotypic, however, will be 2 pink and 2 white at a ratio of 2:2.
The offspring's phenotypic ratio will be 2:2.

Answer:
It is absorbed by the clouds.
It is reflected by clouds
It is reflected by glacial ice.
Explanation:
Solar radiation is the energy that is emitted by the sun which is as a result of nuclear reactions that form electromagnetic energy. It experience different things when it comes in contact with different surfaces. When it comes in contact with the Earth, it is absorbed by it, the cloud reflected part of it and it is also reflect by glacial ice which serve as mirror. Solar radiation can be converted to heat and useful form of energy.
Rods and cones are photoreceptors that are located in the retina of the eye. Rods are responsible for vision at low light levels while cones are responsible for vision at higher light levels. Therefore, rods are very sensitive to light. Rods work well at night when light is low. Cones, however, are responsible for color vision and high visual spatial acuity. Therefore, rods cannot distinguish colors. With these differences, the correct answer is:
A. Rods are very sensitive to light but do not distinguish colors.
