Answer:

Genetic diversity

Explanation:

Genetic diversity is when a population of a species, humans, in this case, have different genes between different individuals. One person may have blue eyes while the others have brown. This shows diversity within the gene pool.

Genetic diversity is also important to the survival of a species. Two-parent reproduction leads to genetic diversity. Having different alleles within a population allows for adaptation. On the other hand, one-parent reproduction does not allow for genetic diversity. This hinders the species because it does not let species to slowly improve the gene pool through natural selection and adaptation.

What are some negative impacts of having this life cycle that might have contributed to a decline in the dragonfly population?
KonstantinChe [14]

Answer:

Dragonflies are important for our environment.

Explanation:

Dragon flies belongs to the ancient family of insects. They are found on every parts of the world and have been from around 300 millions years ago. There are more than 5000 different species of them found in different parts of the world. Conserving dragonflies is important as they considered as a valuable environmental indicators.

Dragon flies are found in the areas where water is available and near grasslands. Their life cycle is an example of an incomplete metamorphosis. The dragon flies lays their eggs near the water or in the water. Dragon flies spends most of the life time as a nymph in the water where they turn into an adult and leave the water. The dragon flies rely on the aquatic ecosystems all through their life. Thus dragonflies are an important indicators of the environment and water quality.

Most of the life cycle of the dragon flies depend on the availability of water and its quality. Polluting water and destroying their habitat will result in the decline of the population of the dragon flies.

In which phase do sister chromatids line up in the middle of the cell, (in 'single-file', without a homologous partner)? Group o
ipn [44]

Answer:

The correct answer is ''METAPHASE I.''      

Explanation:

Metaphase I is the stage in which chromosomal studies are generally performed, because its morphology is very clear. The chromosomes, moved by the mitotic spindle, are placed in the center, between the two asters and form the so-called metaphase plate, in which the chromosomes are positioned in such a way that the kinetochore of each sister chromatid are oriented towards the opposite poles. Keeping chromosomes on the cell equator implies a balance between the forces of the microtubules that tend to move the kinetochores toward opposite poles, so positioning them in the center involves a great deal of energy.In each kinetochore, between 20-30 microtubules can be anchored, which exert traction force towards the pole from which they come, so the metaphase plate is maintained by the balance between the opposite forces of the poles on the chromosomes, which hold their sister chromatids by centromeric cohesin.
