Answer:
D
Explanation:
During metaphase of cell division, the chromosomes line up in the metaphase plate and the spindle fibers from the poles extend and attach to the centromeres of the chromosomes. The spindle then contracts and pull different chromosomes to the opposite poles of the cell before the parent cell divides. If spindle fibers do not form, then the chromosomes will not separate during anaphase.
Therefore, the final cell after mitosis will be a cell with double the number of chromosomes -because if you remember, during interphase, genetic material is replicated so each daughter cell can have its copy-. Due to quality control in the process of cell divisison, this cell will mostly undergo apoptosis, otherwise, it could develop into cancer.
1. Enzyme is the molecule that serves to make reactions work. Enzymes are biochemical catalysts that catalyses chemical reactions in a cell by acting on substrates and convert them to products. Their rate of action increases with increase in substrate concentration, reaching optimum when all active sites of the enzyme are engaged.
2. Plastid are the tiny sacs in the cell that may contain starch. Plastid are major cell organelles found in the cells of plants and algae. Plastids are site for the manufacture and storage of important chemical compounds used by the cell. They often contain pigments used in photosynthesis, and the types of pigments present can change or determine cells color.
3. Lysosome are packets within the cell that contain digestive enzymes. Lysosomes are one of many organelles found in animal cells. they are tiny like sacs filled with enzymes that enables the cell to process nutrients. They contain digestive enzymes which helps in the digestion of worn out organelles, food particles and engulfed viruses or bacteria.
4. Mitochondrion is a structure within a cell that is responsible for production of energy. Energy in a cell is produced through a process of cellular respiration which involves use of nutrients with oxygen gas to yield energy inform of ATP, water and carbon dioxide. The process takes place in the mitochondrion where oxygen acts as proton acceptor in the electron transport chain coupled by production of energy.
5. An Organelle is a small structure that serves specialized functions. A cell is made up of various organelles that help it perform its functions. Each organelle is specialized to perform as specific function different from other organelles, for example ribosomes is an organelle involved in the manufacture of proteins.
6. Golgi apparatus are group of flattened sacs that package and export materials out of the cell. Golgi apparatus also called golgi complex or golgi body, is a membrane bound organelle in eukaryotic cells that is made up by a series of flattened, stacked pouches called cisternae. They are responsible for transporting, modifying, and packaging proteins and lipids into vesicles.
7. Vesicles are tiny sacs connected to the Endoplasmic reticulum and Golgi apparatus. Vesicles are small structures within a cell, or extracellular, consisting of fluid enclosed by a lipid bi-layer. they form naturally during the process of secretion (exocytosis), uptake (endocytosis) and transport of materials within the cytoplasm.
Answer:
Explanation:
A sequence of flowing lava, pyroclastic flows, volcanic eruptions, caldera-forming events, and earthquakes changed the landscape of Yellowstone forever. The pressure exerted by the magma chamber has resulted in measurable ground deformation in certain parts of Yellowstone known as resurgent pressure domes.
Fire Activity also causes the Yellowstone to change. As the number of very large wildfires and total acres burned annually increases, there is an increasing frequency of warm spring and summer temperatures, reduced winter precipitation, and early snowmelt in the Western United States during the last 20 years.
In 1995, the wolf population increased in Yellowstone, causing the deer population to decrease and to change their behavior. When threatened by wolves, deer graze less and move about to aerate the soil.
In the 70 years since the wolves left Yellowstone, the entire ecosystem had collapsed into chaos, with coyotes running riot, and elks overgrazing willows and aspens. Without those trees, songbirds declined, beavers could not build their dams, and riverbanks eroded.
