The oxygen by-product of photosynthesis is created by the splitting of <u>water</u> molecules to replace the electrons ejected from the reaction center of photosynthesis ii.
Photosynthesis is a process whereby organisms containing plastids like green plants and other microorganisms make glucose using carbon dioxide, water and energy from sunlight.
A significant by-product of this process is oxygen, used by animals for respiration. Photosynthesis is of two stages; the light stage, also called photosynthesis i and the dark stage, also called photosynthesis ii.
During the light stage, the energy from sunlight is used to split water molecule into electrons, hydrogen protons and oxygen. The electrons are transported by carriers and used up in the reaction center of photosynthesis ii, while the oxygen is given of as a by-product.

I am assuming you mean the nutrient groups of macronutrients and micronutrients.
Macronutrients:
<em>fats</em>
<em>carbohydrates</em>
Micronutrients:
<em>calcium </em>
<em>zinc</em>
<em>vitamins</em>
Hope this helped :)
Answer:
A. loss of sensation to pressure and touch
Explanation:
Posterior column-medial lemniscus pathway also known as the dorsal column–medial lemniscus pathway (DMLP) is a pathway involved in recognition of sensory simulations and is found in central nervous system.
It is involved in conveying different sensations like like touch and vibration from skin and joints. Therefore, it can be said that the pathway plays significant role in perception of sensory information from different parts of the body. If any damage occurs to the pathway it can result in loss of sense of touch and vibration which is ultimately a lack of ability of a person to sense a touch or pressure in the body.
Hope it helps!
A plant without chlorophyll would not be able to photosynthesise because chlorophyll serves to absorb sunlight, which is used to break apart the bonds in water during photosynthesis. A plant that is unable to photosynthesise is not able to create glucose, hence it would likely die unless it was receiving glucose through another source. This is because the plant relies on the energy it gets from breaking down glucose for important internal functions.
<span>The correct answer is A. Photosynthesis. To conduct photosynthesis, you need chloroplasts and these are found in the leaves which is why the leaves are green. Roots don't have them and they aren't exposed to the sun and don't create energy using photosynthesis. They do however absorb nutrients from the soil.</span>
