Answer:
Some particles went through vacant regions of the atom, while others were redirected by concentrated clusters of positive charge within the atoms.
Explanation:
In Rutherford's experiment, particles either passed straight through the gold foil or were deflected by the positively charged nucleus.
This response is accurate because the particles moved through vacant regions of the atom (not just spaces among atoms), with some being deflected by zones of concentrated positive charge (the nucleus).
In metaphase, anaphase and telophase of meiosis 2 before cytokinesis the condition prevails.
Explanation:
Meiosis is the cell division process that occurs in gamete precursor cells to create gametes. It's a reduction division since the progenitor cells are diploid while the gametes are haploid.
During meiotic division, the cells first go through DNA replication that doubles the DNA content of each chromosome.
Then, via meiosis I, the cell experiences reduction division, transforming the diploid cell into a haploid cell. Thus, a cell with 10 chromosomes becomes one with 5 chromosomes. However, the DNA amount per chromosome remains doubled. This is corrected by the second meiotic division, where each chromosome splits into chromatids with a standard DNA content.
So at each stage of meiosis II,
until cytokinesis occurs, the cells should remain in a haploid state with double the DNA content. [[TAG_45]]
Answer and Explanation:
- In which area (quadrant, etc.) will the physician examine Juan's abdomen?
Ordinarily, the spleen cannot be detected due to its small size. However, if enlarged, it becomes palpable. Its location is beneath the thoracic cage (rib cage) on the left, lying between the 8th and 11th ribs, which corresponds to the left upper quadrant (left hemi-belly).
- Which other organs might be impacted by Juan's enlarged spleen?
The enlargement of the spleen along with liver inflammation indicates mono. Such swelling could influence nearby organs like the stomach, which may be compressed and shifted.
- Why is Juan's spleen swelling rather than his stomach or kidneys?
The spleen plays a crucial role in the immune system, aiding the body in combating infections and filtering out aged blood cells. It can enlarge due to an accumulation of blood cells. When excessively retained, the spleen expands, leading to anemia. An improperly functioning spleen eliminates too many red blood cells while accumulating others.
Since the stomach and kidneys are not involved in blood filtering, they remain unaffected by such accumulation.
These organisms developed exclusively within these nations. They evolved in Australia and New Zealand due to the isolation of these countries, which prevents the introduction of crops or animals from other areas. A significant ocean barrier separates these regions from others, resulting in a unique evolutionary process.
