Write one experiment to show particulate nature of matter |
|
Answer» Answer: potassium permanganate test Explanation: Matter – is anything that occupies space and has mass. Matter exists in three states namely; solid, LIQUID and gas. Experiment Aim: to demonstrate that matter is made up of smaller PARTICLES Apparatus: Beakers, potassium permanganate crystals, water. Procedure Pour water into the beaker till it is half full Dissolve some potassium permanganate crystals until the SOLUTION is purple Transfer half the solution into another beaker and fill it with water Continue the process with other beakers, comparing the colour of the solution through each dilution. Observation result for CHANGE OF COLOUR IN DILUTION The colour of the solution fades AWAY through each dilution until the solution appears colourless. This shows that the particles of potassium permanganate are spread out evenly in the water. Each dilution spreads them out further as the water molecules increase in number. Hence the purple colour fades away with each dilution until it becomes colourless. Conclusion Potassium permanganate is made up of tiny particles. Also, when some salt particles are put in a flask and water added, it is observed that after shaking the flask to dissolve the salt, the volume of the final solution is less than the original volume of the water plus undissolved salt. This is because salt particles fitted into some spaces between the water molecules. Hence the particles of the solution are more PACKED together, reducing the volume of the solution. This also indicates that the particles of water and those of salt differ in size. |

Geological time scale |
|
Answer» Answer: The Geologic Time Scale (GTS) is an arbitrary chronological arrangement or sequence of geologic events, used as a MEASURE of the relative or absolute duration or age of any part of geologic time, and usually presented in the form of a CHART showing the names of the various rock-stratigraphic, time-stratigraphic, or geologic-time units. The table of geologic time spans presented here agrees primarily with the nomenclature, dantes and STANDARD color codes as set forth by the INTERNATIONAL Commission on Stratigraphy. This, however, only goes BACK as far as the age of the Earth (4.54 billion years). A proposal has been made to formally define the periods of the evolution of the Solar System before the Earth was formed going back to approximately 5 billion years. This is added into our chart as the chaotian period.

Gene battery model kya hota hai or kisne dia tha |
|
Answer» hey mate here is ur answer The Britten–Davidson model, also KNOWN as the gene-battery model,is a hypothesis for the regulation of protein synthesis in EUKARYOTES. Proposed by ROY John Britten and Eric H. Davidson in 1969, the model postulates four classes of DNA sequence: an integrator gene, a producer gene, a receptor site, and a sensor site. The sensor site regulates the integrator gene, responsible for synthesis of activator RNA. The integrator gene cannot synthesize activator RNA unless the sensor site is activated. Activation and deactivation of the sensor site is done by external stimuli, such as hormones. The activator RNA then binds with a nearby receptor site, which stimulates the synthesis of mRNA at the structural gene. pls mark this as brainliest. hpe this hlps U |

A particular garden pea plant produce only violet flowers.how will you determine whether it is homozygous or heterozygous dominant explain with help of cross? |
|
Answer» The PEA plant produces only violet FLOWERS so it would be homozygous (PP). The GENOTYPE of a plant can be ensured by a TEST cross in which the plant is crossed with a homozygous recessive plant i.e. pp, white flowers. The test cross gives all violet flowers showing that the PARENT is homozygous for violet colour. |
