Briefly describe the phases of cell division

Answers

Answer:

Prophase: Chromosomes become visible as paired chromatids and the nuclear envelope disappears

Metaphase: Sister chromatids are aligned in the middle

Anaphase: Chromatids are split apart and move toward opposite ends.

Telophase: Reverse of prophase and mitosis ends.

Explanation:

More: (If the answer was too breif)

Prophase

• Chromatin condenses into

chromosomes

• Appear as sister chromatids

• Nucleoli disappear

• Mitotic spindle begins to form

• Centrosomes begin to move to opposite ends

• Nuclear envelope begins to breakdown or fragment

Metaphase:

• Centrosomes at opposite ends and mitotic spindle

fully formed

• Sister chromatids (chromosomes) align across

the middle and spidle are attached to both sides

Anaphase:

• Sister chromatids (chromosomes) are split apart and move away toward opposite ends

• Cytokinesis begins during the later stages of anaphase

• Cleavage furrow develops when cytokinesis begins

Telophase:

• Chromosomes become less condensed

• Spindle disappears

• Nuclear envelope forms

• Mitosis ends

• Two daughter nuclei have formed

• Cytokinesis continues

• Usually finishes after telophase

Deforestation is a source of anthropogenic, or human caused carbon dioxide emissions because cannot consume carbon dioxide moleculesGiven that plants and trees reduce the amount carbon dioxide in the atmosphere, what does this indicate about the relative rates of photosynthesis and respiration in plants

Answers

Answer:

Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. The carbon cycle. Most of Earth’s carbon is stored in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles. NOAA technicians service a buoy in the Pacific Ocean designed to provide real-time data for ocean, weather and climate prediction. NOAA buoys measure carbon dioxide NOAA observing buoys validate findings from NASA’s new satellite for measuring carbon dioxide Listen to the podcast Carbon storage and exchange Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths. Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources. Processes such as erosion release this carbon back into the atmosphere very slowly, while volcanic activity can release it very quickly. Burning fossil fuels in cars or power plants is another way this carbon can be released into the atmospheric reservoir quickly.
