A scientist wanted to investigate whether light is required for the germination of seeds. She filled two plant pots of the same size with equal amounts of
soil.
Pot 1 was labelled 'LIGHT and Pot 2 'DARK'. Five lettuce seeds were planted
in each of the pots. Both plants were given sufficient water.
Pot 1 was put in direct sunlight. A cardboard box was placed over Pot 2
and no light was allowed to enter.
21.1
Write down a hypothesis for the investigation.
Pleas
it reserved​

The correct hypothesis would be -

"if the light is required for seed germination of seed, then in the absence of light lettuce seed will not germinate"

Explanation:

The hypothesis is always based on a question one wanted to answer. The hypothesis is the possible explanation of a world natural problem. One needs to make his hypothesis on the basis of the research he made.

To test the hypothesis one needs to develop an experiment like here formed an experiment to test if the light is required for the germination of seeds. Thus, hypothesis would be "if the light is required for seed germination of seed, then in the absence of light lettuce seed will not germinate"

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
