Briefly describe the phases of cell division
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

Two students conduct the same experiment, but they get different results. What should the students do next? A. The students should check their procedure and tools for sources of error. B. Both students should throw out their data and start over. C. The students should compare data with other students and then use the data from the student who was closest to the rest of the class. D. The students should find the average of each data set and each report the average data.
Answer:
D is the answer
Explanation:
hope it helps
Hey there!
Let's solve your problem:
The answer is: A
If two students do the same experiment, but get different results, they should not throw it away. It may be a phenomenon and they both got different results. They should not compare to the rest of the class either. Finding the average of the data would not help either. The answer is A

A student is trying to model an ocean environment. What is the MOST important factor the student should add to the aquarium in order to make sure that the model is accurate?
A.starfish
B.seaweed
C.salt water
D.coral reef
Answer:
C: salt water
Explanation:
everything would be dead if there was no water
The most important factor while preparing a model of an ocean environment is Salt water. Marine ecosystems show high salinity. Thus, the correct option is C.
What is Ocean environment?Ocean ecosystems or environments are characterized by the important factors which include the availability of light, food and nutrients. Oceans have some unique properties which include high salinity, the freezing point which is slightly lower than that of fresh water, density which is slightly higher than other waterbodies, electrical conductivity which is much higher, and the slightly basic nature.
Oceans are important as they feed us, regulates the climate, and generate most of the oxygen which we use for breathing. They also serve as the foundation for much of the world's economy, supports important sectors from tourism to fisheries to the international markets.
Therefore, the correct option is C.

What is eutrophication
Answer:
Eutrophication, dystrophication or hypertrophication, is when a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae. This process may result in oxygen depletion of the water body after the bacterial degradation of the algae.

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
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.Explanation:

Answer:
I really don't know I'm sorry dude but I needs the points
Answer:
The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.
