Why do some plants perform C4 photosynthetic pathways instead of the more common C3 pathway?

The cause of the color patterns in the sky is when light is diffracted from water droplets within the clouds, the amount of diffraction that occurs depends on the wavelength of the light, and shorter wavelengths are diffracted at a greater angle than longer ones which is therefore denoted as option D.

This is a term which is described as the process of light bending around an obstacle or spreading out after it moves through a small or tiny space.

We should also be aware that it  is dependent on the wavelength of the light such that those with a shorter wavelengths are usually diffracted at a greater angle than longer ones which is therefore the reason why the color pattern is observed in the sky and is therefore the reason why it was chosen as the correct answer.

Protein synthesis involves transcription and translation. During transcription, mRNA complements the DNI template strand. During translation, mRNA codons specify the amino acids that must be added to the growing polypeptide by tRNA.  

-----------------------  

Before answering all these questions, let us review some framework.

Nitrogenated bases that conform nucleic acids correspond to purines and pyrimidines.

⇒ In the DNA molecule, Adenine always forms pairs with Timine , while Guanine forms pairs with Cytosine.

⇒ In RNA molecule, Timine is replaced by Uracil. So Adenine forms pairs with Uracil, and Guanine forms pairs with Cytosine.

Codons are short sequences of three nucleotides that carry the genetic information for the aminoacids´ assembly.

mRNA has start and end codons. Between them, there are codons that code for the amino acids to be added to the chain. The start is the signal of the synthesis initiation. When the ribosome reaches the end codon, protein synthesis is over.    

There exists a total of 64 codons.

There is no six-legged starfish in existence. Fixation may be to blame. Fixation is a condition in which there is only one allele in the population and the other allele is extinct.

Given that in total 26 starfish are normal and 1 has 6 legs.
Genotypic frequency of 6 legs is 1/27 =0.037.
Genotypic frequency is always 1 and is given by p2 + 2pq + q2 = 1.

Allelic frequency = p + q = 1
So, frequency of p = 1-0.19 = 0.81

After 2 years, the Chi-square value:

            Observed    Expected    O-E      (O-E)2         (O-E)2/E

5 leg: 0.81               0.6           0.16        0.0256        0.039385

6 leg: 0.19               0.35      -0.16        0.0256        0.073143

                                                                                              0.112527

So Chi-square value is 0.112527.

Genotypic frequency of 6 legs is 4/31 =0.129

        P = 1 - 0.35

        P = 0.65

So new allelic frequency for 6 legs is 0.35.

New allelic frequency for 5 legs is 0.65.

This random change of allelic frequency is called as genetic drift.

To support the claim that the cit mutation increases the fitness of the bacteria, we need to consider the following reasoning:

1. Cit mutation and utilization: The cit mutation likely affects the bacteria's ability to utilize or metabolize citrate. Citrate is a molecule commonly found in the environment but is generally not utilized by bacteria in the absence of specific adaptations. If the cit mutation enables the bacteria to utilize citrate as a carbon source, it provides an advantage by expanding the range of available nutrients for the bacteria.

2. Nutrient availability: Bacterial fitness is often influenced by the availability of nutrients. If the presence of citrate in the environment is abundant, and other resources are limited, the bacteria with the cit mutation would have a competitive advantage over non-mutated bacteria. They would be able to access additional energy and carbon sources, potentially leading to increased growth rates and higher overall fitness.

3. Competitive exclusion: In ecological settings, competitive exclusion refers to the phenomenon where one species outcompetes and displaces another. If the cit mutation provides a significant advantage in utilizing citrate, bacteria without the mutation may be outcompeted and excluded from the niche where citrate is present. This can lead to a higher fitness for bacteria carrying the cit mutation.

4. Long-term evolution: Over time, the accumulation of beneficial mutations can drive the evolutionary success of a population. If the cit mutation confers an advantage, bacteria carrying this mutation may exhibit greater adaptation and survival in environments where citrate is available. This can contribute to the increased fitness of the bacterial population over multiple generations.

Overall, the claim that the cit mutation increases the fitness of the bacteria is supported by the reasoning that it enhances nutrient utilization, provides a competitive advantage, and potentially leads to long-term evolutionary benefits.

Selfing refers to the process of self-fertilization, i.e., self-pollination by an individual that has both male and female reproductive structures. In plants, selfing can occur in a hermaphroditic flower in which both the stamens and the pistil are present. It leads to a reduction in genetic diversity within the population.

Let's see how it affects the frequency of heterozygotes in a population. Computation:

Initially, the population composed of 0.50 heterozygotes.

Thus, the initial frequency of heterozygotes, p = 0.50.

The frequency of homozygotes would be \(q = 1 - p = 1 - 0.50 = 0.50\)

After one generation of selfing, the frequency of homozygotes would be

\((q × q) + 2(p × q)= (0.50 × 0.50) + 2(0.50 × 0.50)= 0.25 + 0.50 = 0.75\)

The frequency of heterozygotes would be

\(2(p × q) = 2(0.50 × 0.50) = 0.50\)

After two generations of selfing, the frequency of homozygotes would be

\((0.75 × 0.75) + 2(0.25 × 0.75) = 0.5625 + 0.375 = 0.9375\)

The frequency of heterozygotes would be 2(0.50 × 0.50) = 0.50

After three generations of selfing, the frequency of homozygotes would be

\((0.9375 × 0.9375) + 2(0.0625 × 0.9375)\)

= 0.8789The frequency of heterozygotes would be \(2(0.50 × 0.50) = 0.50\)
