Answer:
<em>D) lining up of chromosomes in the cell</em>
Explanation:
Prophase can be described as the first stage of cell division. During this phase, The chromatin material condenses and becomes compact so that the chromosomes become visible. The nuclear envelope disintegrates and the nucleolus disappears. Hence, the choices mentioned in option A, B and C occur by the end of prophase.
Metaphase is the third phase of cell division. During this phase, the chromosomes line themselves in the centre of the cell. Hence, the lining of the chromosome does not occur by the end of prophase. This occurs during the third stage.
A. Log and replant ¼ of the forest every 15 years.
Explanation:
As Sam utilizes simulation technology to demonstrate the greenhouse tactics that can maintain the woodlands and deliver an endurable source of food and wood, as it has already been given that the simulation needs a regeneration rate of 60 years.
The tactics that would allow the fast regeneration and longevity of the forest preserves would stand to log and replant one-fourth of the forest every fifteen years. Hence providing the most sustainable wood resource.
Answer:
a. Trisomic
Explanation:
A trisomy is a genomic phenomenon whereby a particular chromosome is present in three copies. In this case, the trisomy involves the chromosome P, being this species a tetraploid with 5 pairs of homologous chromosomes (2n = 10). In humans, the trisomy for chromosome 21 is one of the most common types of aneuploidies that lead to the Down syndrome by producing alterations in gene expression patterns that are associated with changes in the phenotype
Honestly im just trying to get my points
Because they feel tickle. :-)
