Osmosis is also used for preserving fruits and meats, though the process is quite different for the two. In the case of fruit, osmosis is used to dehydrate it, whereas in the preservation of meat, osmosis draws salt into it, thus preventing the intrusion of bacteria.
how does the colour of star help to find its age
Answer:
As stars age, they run out of hydrogen to burn, decreasing the amount of energy they emit. Thus, younger stars can appear bluer while older ones appear more red, and in this way, a star's color can tell us something about that star's age.

what is the effect of water temperature on corals from inshore and offshore reefs?
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.

Answer:
Agricultural, Commercial, Public, and Domestic
The three main areas where water may be used in a society is agricultural, domestic and household activities.
What are uses of water?Our communities rely heavily on water to function. There wouldn't be any local commerce or industry without water. Public swimming pools, city parks, and firefighting all require a lot of water.
To deliver a consistent supply of water to our taps each day, a variety of pipes, canals, and pumping stations operated by our public water systems are necessary.
Every day at home, the typical American household uses more than 300 gallons of water. About 70% of this use takes place indoors.

What are the roles of the nucleus, cytoplasm, mitochondria, and the cell membrane in eukaryotic cells? in your own words nothing from the internet
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.
what cells release histamine during allergic responses
Answer:
Histamine is a substance that is released by the body during an allergic reaction. Mast cells, which are a type of white blood cell, release the histamine, and this triggers a process which is most commonly referred to as the “inflammatory immune reaction”.
Explanation:
Antihistamine solutions can reduce allergies. I am allergic to mosquito bites.
The cells release histamine during allergic responses are the mast cells.

The chemiosmotic hypothesis states that the energy for the production of ATP during photosynthesis comes from the Mitochondria.
The mitochondria is regarded as very important and the power(energy) house of the cell as a lot of ATP synthesis activities takes place in this organelle.
The hypothesis was used to prove that most of the ATP production that takes place in respiring cells comes from the electrochemical gradient present across the inner membranes of mitochondria.
ATP is formed from the break down of the molecules rich in energy such as glucose and the use of energy of NADH and FADH₂ which are formed from its breakdown.
