Plant cells can be identified by their rigid cell wall, chloroplasts, a large central vacuole, and plastids, unlike animal cells that lack these structures but have organelles such as centrioles and lysosomes.
Explanation:When distinguishing between plant cells and animal cells, several key cellular structures can be observed. Plant cells have a rigid cell wall made of cellulose that surrounds the plasma membrane, which helps in maintaining a distinct shape and providing structural support that enables plants to grow upright. In contrast, animal cells lack this cell wall.
One of the most definitive features of plant cells is the presence of chloroplasts, which are the sites of photosynthesis, a process unique to plants and some protists that converts solar energy into chemical energy. Animal cells do not have chloroplasts. Additionally, plant cells often contain a single large central vacuole that holds materials and wastes, and helps to maintain proper pressure within the plant cells to provide structure and support. Animal cells may have small vacuoles, but not a large central one as seen in plant cells.
Another difference is that plant cells have plasmodesmata, which are channels between the cell walls of adjacent plant cells, facilitating communication and transport between them. They also possess various kinds of plastids like chloroplasts, leucoplasts, and chromoplasts that are involved in processes such as photosynthesis, storage, and imparting color. However, animal cells contain other organelles like centrioles and lysosomes that are absent in plant cells.

What three factors led to the overthrow of the Chaldean empire? Explain.
One of the factors that lead to the downfall of the Chaldean empire was the Persian invasion. Although Belshazzar tried to fend off the Persian army, it was too massive to hold off. Another factor would be that Belshazzar was also betrayed by Gobryas, which lead the forces against the Persian army even at greater advantage. Other than the governor, there were also other parties in the state that were also against the Chaldean kingdom. Lastly, there were also the foreign Jew exiles whom Cyrus the Great allowed autonomy and freedom to go back to their homes. From there, it was Cyrus the Great who brought the fall of the Chaldean empire.

What can happen when you have taken much more than the normal amounts of vitamins?
Answer:
Taking vitamins is a daily routine that has millions of people around the world. However, taking too many vitamins can lead to an overdose and be dangerous to health.
Explanation:
For example, water-soluble vitamins (vitamin B1, B2, B3, etc.) are excreted from the body and are not stored in the tissues. However, an overdose of some of these vitamins can induce side effects, such as irreversible nerve damage, or liver damage.
Meanwhile, fat-soluble vitamins (vitamin A, D, K, etc.) do not dissolve in water and can be stored in your body's tissues. Due to the accumulation of these vitamins, they are likely to produce toxicity or harmful effects much more than water-soluble vitamins.

The Aleutian Trench is an area where the oceanic Pacific Plate is converging with the continental North American Plate. What can you conclude is happening in this area?
Final answer:
In the Aleutian Trench, subduction of the Pacific Plate beneath the North American Plate causes frequent earthquakes and volcanic activity, and is part of the seismically active Ring of Fire.
Explanation:
The Aleutian Trench is a region where the oceanic Pacific Plate is converging with the continental North American Plate. In this area, a process called subduction is occurring, where the denser oceanic plate is sliding beneath the less dense continental plate. This subduction leads to frequent earthquake and volcanic activity due to the melting of the subducted plate that forms magma, which can then rise to the surface to create volcanic cones. Additionally, the subduction zone in the Aleutian Trench area is part of a larger zone known as the Ring of Fire, characterized by high seismic activity and numerous volcanoes encircling the Pacific Ocean.
