what is the effect of water temperature on corals from inshore and offshore reefs?
Answers
Answer:
When the water gets too warm, the algae can no longer live inside corals, so they leave. The corals then turn from green to white, called coral bleaching. Climate change has been causing the Earth's air and oceans to get warmer. With warmer oceans, coral bleaching is becoming more widespread.
Explanation:
When the water temperature rises too high, algae can no longer live inside corals and leave. Coral bleaching occurs when the corals turn from green to white.
What are coral reefs?A coral reef is an underwater ecosystem characterized by corals that build reefs. Reefs are made up of coral polyp territories hosted along by calcium carbonate.
The vast bulk of coral reefs are mainly composed of stony corals, which have polyps that coalesce together.
Coral reefs grow in shallow water with temperatures ranging from 68° F to 97° F. The Indo-West Pacific biogeographic region contains more than 90% of the world's coral reefs.
When the temperature of the water rises too high, algae can no longer live inside corals and must leave. Coral bleaching occurs when corals alter color from green to white.
The Earth's air and oceans are becoming warmer as a result of climate change. Coral bleaching is becoming more common as the oceans warm.
Thus, this is the effect of water temperature on corals from inshore and offshore reefs.

where are the motor proteins that move chromosomes toward the poles of the mitotic spindle located?
Answers
Answer:
They are at or near the ends of the microtubules. I hope this helps you! :D
Microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.
What are motor protein?Motor protein are defined as a group of molecules with the ability to travel across the cytoplasm of animal cells. Molecular motors called motor proteins move along the cytoskeletal filaments of the cell by hydrolyzing ATP. They provide a variety of tasks for biological systems, such as facilitating intracellular trafficking along biopolymer filament tracks and regulating filament sliding during muscle contraction.
Microtubules are defined as the cytoskeleton is made up of tubular-structured polymers, which are present throughout the cytoplasm. Microtubules play a variety of roles in dividing cells, including the construction of the mitotic spindle and axon extension in neurons.
Thus, microtubules near the cell plate are the motor proteins that move chromosomes toward the poles of the mitotic spindle located.

What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells? in your own words nothing from the internet
Answers
Answer:
What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells?
Explanation:
1.The cell membrane holds the cell's internal contents from its environment
2.the nucleus, the cell's "brain", holds the cell's DNA in the form of chromosomes, and makes protein codes that tell the other organelles to function in a certain way once the codes are made into literal proteins and passed around the cell
3.The cytoplasm is the gelly fluid inside the cell. It is the place for chemical reaction, and provides a place where other organelles can operate within the cell properly, and the cytoplasm keeps the cells from moving around.
4. The main job of the mitochondria is to convert nutrients into energy through cellular respiration, making ATP. the mitochondria are known as the powerhouse of the cell. In addition to supplying energy, the mitochondria is involved in a range of other processes,like signalling, cellular differentiation, cell death, as well as control of the cell division cycle and cell growth.
