what is the water intake of chlorophytes
Answers
Answer:
Huge amount.
Explanation:
There is higher water intake of chlorophytes because the chlorophytes prepare their own food by using water and carbondioxide just like plants in the process of photosynthesis. These chlorophytes have chlorophyll which able these algae to make their food from sunlight and they can't live without water of dry places. Chlorophyte is also known as Prasinophyte which is a green algae. So due to photosynthesis, the chlorophytes needs high amount of water for making food.
Mediterranean forests, dry woodlands, and shrublands often have plants called sclerophytes living in them. What adaptation do these plants have that help them survive in this biome?
Answers
Answer:
he special characteristics that enable plants and animals to be successful in a particular environment are called adaptations. Camouflage, as in a toad's ability to blend in with its surroundings, is a common example of an adaptation. The spines on cycad leaves, keep animals from eating them.
Explanation:
Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.

O oxigênio é importante um gás na quebra de ligações entre os átomos que formam a glicose para a produção de energia. Por que a presença de ferro no nosso organismo é importante para este processo?
Answers
Answer:
It transport oxygen from lungs to the cells.
Explanation:
The presence of iron in our body is very important for this process because iron is responsible for the transportation of oxygen. Hemoglobin is made up of iron that takes oxygen from the lungs to each and every cell. Iron is an essential element for the formation of blood in human body. About 70 percent of body's iron is found in the red blood cells of our blood called hemoglobin and in the muscle cells called myoglobin. So we can say that iron is very important for the release of energy in the process of respiration.

Answers
Answer:
4)WRITE FULL FORM OF IUPAC.
Explanation:
1.Dry ice is the solid form of carbon dioxide. It is used primarily as a cooling agent, but is also used in fog machines at theatres for dramatic effects. Its advantages include lower temperature than that of water ice and not leaving any residue.
2.The Haber process, also called the Haber–Bosch process, is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today. It is named after its inventors, the German chemists Fritz Haber and Carl Bosch, who developed it in the first decade of the 20th century.
3.Ammonia gas
Ammonia gas is used as a developer in diazotype method to make blue prints.
4.The International Union of Pure and Applied Chemistry (IUPAC /ˈaɪjuːpæk, ˈjuː-/) is an international federation of National Adhering Organizations that represents chemists in individual countries.
5. All metals have some amount of resistivity to electrical currents, which is why they require a power source to push the current through. The lower the level of resistivity, the more electrical conductivity a metal has. Copper has low resistivity, and therefore is an excellent conductor.
6.gold and silver are used to make ornaments because in they are the least reactive and do not react with any thing . Gold and silver are ductile (cam be made into thin wires ) and they have a metallic lustre.
7. I am too smalll I am frecking 10 yrs

6)Silver is used to make mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts and batteries.
7)Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality.
