Answer:
Adaptations to a common environment and examples of convergent evolution
Explanation:
Convergent evolution is a process by which two independent and phylogenetically separated organisms, get to develop similar structures or behavior to survive. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.
Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need of different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.
In the exposed example, Ichthyosaurs (reptile) and fishes are separated species on evolutive time, corresponding to different phylogenetic lineages. Both of them inhabit the same aquatic environment. Pressures of the habitat acted on them and modeling their phenotypes. These species need to adapt to living in water, moving, feeding, scaping, chasing, etc. So both species arrived at the same solution. They developed dorsal fins and tails, which are important to stabilize the body in the water while swimming, making it more hydrodynamic and getting to propel better.
A physical property is any property that can be measured without changing the composition of matter. Physical properties are used to observe and describe matter.
Deoxyribose is the substances along with sugar and phosphates . The rungs of the ladder are made up of 5 nitrogenous bases adenine, thymine, cytosine, and guanine.
<span>The answer is a sexual reproduction. This is due to the formation
of gametes that enable the variation of the offspring of the parents. Firstly,
each gamete contributes half the genetic material (alleles)from either parent.
The dominant alleles will show in the phenotype of the c=ofspirng. Additionally,
during meiosis (the process that makes gametes), recombination of genetic
material can occur hence transferring unique combination of genes from that of
the parent. Therefore, there are many possible combinations of gametes that
gives the offspring variance from the parents</span>
