Why artificial reproduction in fish?
Some species are becomming rare or are needed but are hard to breed in sufficient numbers. Others (food fish) are needed to supply fish for eating and others are needed to return to the wild. (restocking)
The energy needed for active transport is usually supplied by what?
The energy needed for active transport is usually supplied by Mitochondria and ATP.
What skills are needed to take care of animals?
There are may skills needed to take care of animals such as love. You will need to be responsible and caring as well.
What would happen if electrons from photosystem 2 weren't replaced?
If electrons from photosystem 2 weren't replaced, the electron transport chain would be unable to continue and ATP synthesis would stop. This would disrupt the light-dependent reactions of photosynthesis and prevent the generation of NADPH, which is needed for the synthesis of sugars in the Calvin cycle. Ultimately, this would lead to a decrease in the production of glucose and other organic compounds.
Why did photosystem II evolve first?
This is a speculative area! The most detailed studies and reasoning relevant to this question are perhaps those of Nathan Nelson, who has used genomic analyses of Eubacteria, Archaea, and eukaryotes to draw up a tentative evolutionary tree of photosynthetic reaction centers. His conclusion is that photosystems I and II, or rather, reaction centers of these two types, had a common origin about 2.5 Ga (billion years ago). - - - photosystem II - - - It was Kodak that invented the first, ever, photosystem for every man to use. In those days you needed to buy the camera and after having taken all the shots, you simply returned the camera (intact) to Kodak. Kodak would then make prints of your photos and return it. --- But I think you meant the photosystem used in photosynthesis lol photosystem 1 was discovered first, but it does not mean that it evolved first. Photosystem 2 is actually first in the process of capturing light energy. But as you can see, the answer is mainly a mystery, just like "Which came first, the chicken or the egg?" Hope this helped --
How plants separate H2O?
They use energy of sunlight to dissociate water.Process is called photolysis.It takes place in Photosystem (ii).Photolysis gives electrons needed to neutralize possitively charged P680 reaction centre.This reaction also produces oxygen and protons. 2H2O--->O2+4H+ 4e
How many electrons are needed to fill one orbital?
8 electrons
How many electrons are needed to fill the second outer energy level?
8 electrons
What constitutes an electrons group?
lone pair of electrons & bonded pairs of electrons
Where do fanfares originate from?
From the Middle Ages when military functions needed hosting.
Why filament is needed in CRO?
A filament is needed in a Cathode Ray Oscilloscope (CRO) to emit electrons in the cathode-ray tube. The electrons are accelerated towards the screen to create the electron beam, which is then deflected to produce the display. The filament heats up and emits electrons through thermionic emission, contributing to the functioning of the CRO.
Elements in the same group have similar properties because they have the same?
the same number of electrons needed to fill their octet, the same number of valence electrons,
What is the least number of of electrons needed in shell?
