What's a question that could be answered by observing chromosomes of different species of animals

Answers

Answer 1
Answer:

Answer:

we can ask questions related to karyotype, such as: how many chromosomes a certain species have? known as chromosome count, how large are the chromosomes of one species compared to another? what are the taxonomic relationships between some species?

Explanation:

when we observe chromosomes, we´re describing the karyotype, which varies among different species, the study of the karyotype is known as karyology, and thought some techniques such as stainings, can provide information such as number of chromosomes, positioning of centromeres, differences in size or distribution of heterochromatic region, taxonomic relationships, among other. in humans, there are 46 chromosomes, and we can see for example the sex chromosomes, and determine the sex and other physical characteristics
Answer 2
Answer: 1. what clue  to the presence of certain genetic disorders can be seen in  karyotype?                                                                                                               2. why might a lab worker attempting to diagnose a genetic disorder prefer to work with photographs of  chromosomes rather than the chromosome themselves?                                                                                                             3.why would it be much difficult to construct a karyotype of unstained chromosomes?

Forested land in the Amazon basin is currently being cleared for agriculture, just as land in the Midwestern U.S. was cleared for agriculture in the 19th century. The growth of plants is influenced by soil fertility, the naturally-occurring concentration of plant nutrients in the soil. Which statement below do you think best describes the relative soil fertility levels in Amazonian soils and soils in the agricultural Midwest?a. Amazonian soils have higher fertility than Midwestern soils
b. Amazonian soils have lower fertility than Midwestern soils
c. Amazonian soils have roughly equal fertility as Midwestern soils

Answers

Answer:

The correct answer is statement b.

Explanation:

This is due to the fact that the reduction of the vast majority of forest land, that is, mainly in Brazil has resulted in the extinction of the unknown and the familiar species. This has also declined the biological diversity and thus has immensely affected the fertility of the soil.  

The soil has turned shallow and thus are less fertile in comparison to the Mid-Western United States. The Midwestern parts of the United States possess variety of soils, which are produced due to the glacial deposits and thus provides more fertility to the soil.
