Adaptation is a heritable trait. The increase of adaptive evolution by the frequency and effectiveness of an advantageous character over time. Organisms became better adapted to their environment. We have so many species in the world because species have adapted to every possible niche. Different habitats and environment have resulted in different modified organisms.
Some of the options for survival and reproduction include genetics ecology, human evolution, molecular evolution, bioinformatics, geology and sociology.
1. Whorls
2. Organs
3. Symmetry
<u>Explanation:</u>
Some important traits that influence the reproductive success of a flower include: the presence or absence of whorls, the fusion of organs to one another, and the overall symmetry of flowers.
In the process of reproduction in plants, the male and female gametes are produced and transfer of the male gametes to the female ovules occurs. This process is called as pollination. After pollination occurs, fertilization happens and the ovules grow into seeds within a fruit
Floral zygomorphy confers a reproductive advantage to rare plants" as a result of the enhanced pollination efficiency.
Hey again,
The answer you are looking for is B).
Just as proteins consist of long chains of amino acids, DNA and RNA consists of nucleic acid chains called nucleotide's. Nucleotide's are composed of three units: base, sugar (monosaccharide) and phosphate. Bases are found in both DNA and RNA. As seen below, they are adenine, cytosine, guanine, thymine, and uracil.
Hope this helps!!!!!!

Answer now it is easier for animals to adapt
Explanation:
Answer:
genes for flower color and edge shape are linked. They do not assort independently.
Explanation:
<u>Available data:</u>
- test cross between a purple-flowered pea plant having serrated leaves and a white-flowered pea plant having smooth edges.
- serrated leaves → dominant trait
- smooth edges → recessive trait
- purple color → dominant trait
- white color → recessive trait
- F1: 4 purple-serrated:1 purple-smooth:1 white-serrated:4 white-smooth.
There are two genes involved in the cross. The expected ratios are 1:1:1:1 because we assume genes assort independently. However, we see a different phenotypic distribution. When phenotypic ratios differ from the expected ones, it means that genes are linked.
To know if two genes are linked in the same chromosome, we must observe the progeny distribution. If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. But if instead of this distribution, we observe a different one, that is that phenotypes appear in different proportions, we can assume that genes are linked in the double heterozygote parent
