a) testiable

b) falisable

c)both of the abov e

d) none of the above

In an experiment, the hypothesis is If the wavelength of the light shining on a plant is shortened, the rate of photosynthesis is slowed down. This hypothesis is testiable  and falisable

Explanation:

Various conditions will influence the pace of photosynthesis, concentrate on following three:

(1) Temperature: Photosynthesis is constrained by enzymes (organic impetuses), and enzymes are delicate to changes in temperature. As temperature builds, the pace of photosynthesis increments since reactants have increasingly dynamic vitality thus more crashes will occur. The rate will increment until the ideal temperature is come to. In the event that the temperature continues expanding past this point, enzymes will denature and hence the pace of photosynthesis will drop.

(2) Light intensity: Light is consumed by chlorophyll in plants, which convert light vitality into substance vitality or ATP. As the light intensity builds, the pace of photosynthesis increments until a specific moment that all the accessible chlorophyll gets soaked with light (they are working at the greatest limit). Now, the photosynthetic rate will level.

(3) Carbon dioxide focus: Carbon dioxide is associated with the obsession of carbon to make natural particles. As carbon dioxide fixation increments, so do the pace of photosynthesis, since increasingly natural particles can be created. At a specific focus, the pace of photosynthesis will level on the grounds that the enzymes liable for carbon obsession are working at full limit.

From the above factors explanation, it proves that hypothesis might be right and wrong both.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
