Where do plants obtain the oxygen necessary to utilize foods? directly from products of photosynthesis from the splitting of wat
IceJOKER [234]

Answer:

from the splitting of water molecule.

Explanation:

The splitting of water molecules  by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis  of enzymes of Photo system 11.

It involves the splitting of water molecules into;

hydrogen ion/protons.

Oxygen

and electron.

<u> Oxygen is  the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration</u><u>.</u>This is the source of oxygen fro cellular respiration in animals.

the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02  to form carbohydrate in light independent reaction

molecules are attracted to one another by van der waals forces. how do van der waals forces compare with ionic and covalent bond
vitfil [10]
<h2>Answer:</h2>
  1. Ionic bond: It is the bond  formed by the complete transfer of electron from one atom to an other atom.
  2. Covalent bond: It is the bond formed by the mutual sharing of the electrons.
  3. Van der waal: These are weak interactions between one molecules with other polar or non polar molecules to hold to each other by weak force of attraction.
<h2>Explanation:</h2>
  • <u>Similarities between van der waal, ionic bonds and covalent bonds:</u> All of them are a type of inter-molecular forces, in which ionic bonds are stronger than covalent bond and van der walls forces. And covalent bonds are stronger than van der wall forces.
  • <u>Difference between van der waal and ionic bonds:</u> Ionic bonds are formed by complete transfer of electrons from one atom to an other atom. Covalent bond are formed by sharing of electrons while in van der waal, there is a slight attraction when oppositely charged molecules come close to each others.

Result: Van der wall forces are weakest among ionic and covalent bonds.

VladimirAG [237]

Answer:

The two potential difficulties that might have troubled Darwin’s contemporaries are:

1. Lack of transitional forms

2. Shortage of time for the varying forms to evolve.

Explanation:

Two conceivable difficulties that might have given Darwin’s contemporaries some tough work is the timeline given for evolution. This is due to the proposed age of the earth at the time of this study and the confounded numbers of individuals going through evolution.

This results from Darwin highlighting these difficulties in his essay.
