Let v1 be the speed of light in medium 1 and v2 be the speed of light in medium 2. The refractive index of medium 2 with respect to medium 1 is given by the ratio of the speed of light in medium 1 and the speed of light in medium 2. This is usually represented by the symbol n21.

Cooking utensils have the copper coating at the bottom because copper is a good conductor of heat.

Gagandeep Singh 1 day, 11 hours ago

Utensils have copper coating at their bottom because copper is a good thermal conductor. It helps the food to get cooked faster due to its high thermal conductivity. Hence utensils have copper coating at the bottom

Sameer Kumar 1 day, 12 hours ago

The utensils of ancient time is made up of copper because that time we are unable to use the steel and Aluminium. And now we know that how is the utensils formed by the help of Steel and copper is expensive than steel and Aluminium so we use aluminium and copper utensils. Copper utensils are used in ancient time not now

Heterotrophic is a type of nutrition where organism depend on other organism for their food. In these mode of nutrition plant or animal does not make their own food rather than depending on other for their food. Heterotrophic nutrition are of 3 types-- Saprophytic,holozoic,parasitic...

Heterotrophic nutrition is a type of nutrition in which organisms depend upon other organisms for food to survive. Heterotrophic organisms have to take in all the organic substances they need to survive. we are also dependent because we also take vegetables and fruits and from animals we take meat, milk,fisheries. All animals, fungi, and non-photosynthesizing plants are heterotrophic. In contrast, green plants, red algae, brown algae, and cyanobacteria are all autotrophs, which use photosynthesis to produce their own food from sunlight

DNA is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. DNA is a nucleic acid along with certain proteins and carbohydrates. Nucleic acids compose the three major macromolecules essential for all known forms of life. Most DNA, molecules consist of two biopolymer strands coiled around each other to form a double helix. The two DNA strands are known as polynucleotides since, they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase.

The remains of animals or plants that lived in the past are known as fossils. The fossil bird Archaeopteryx looks like a bird, but it has many other features that are also present in reptiles. This is because Archaeopteryx  had feathered wings like those of birds, but teeth and tail like those of reptiles. Thus, the study of fossils provide evidence for evolution.

The increase in the electric potential as one goes up through a height of 50 cm is 5 V.

Explanation:

Given values in the question :

             E = 10 n/c

             E is A uniform electric field

             Change in height, ds = 50 cm  

             "ds" is a height  

Converting height centimeter to meter  :

(i.e ) One centimeter is one-hundred  of a metre.

       It would take 100 cm long to equal a single meter in length .

                              

Change in electric potential, dv = E.ds    

                                               dv = 10×0.5

                                               dv = 5 v

Thus, 5V raise the electric potential as one climbs up to 50 cm in height.

Homologous Organs

Analaogous Organs

Homologous organs have similar origin  n basic structure but perform different functions in different organisms

Analogous organs are different in basic structure but perform same functions.

Homologous organs show divergent evolution

Analogous organs show convergent evolution.

They develop in related organisms.

They develop in unrelated organisms.

Example- Forelimb of a frog and man seem to be built from the same basic design of bones but they perform different functions.

Example- Wings of birds and bats look similar. But in birds wings are covered by feathers all along the arm but the wings of bats is skin folds stretched between elongated fingers.

Advantages :

1}These are the main source of power generation.

2}These projects control the floods because water can be stored in them. These projects have converted many, 'rivers of sorrows' into 'rivers of boon'.

3}Thes projects are the main source of irrigation and also help in conserving soil.

Disadvantages:

1}Dams also fragment rivers making it difficult for aquatic fauna to migrate for spawning, i.e , to produce eggs.

2}It resulted in displacement of local communities.

3}The multipurpose projects induced earthquake, caused waterborne diseases.

Dominant trait: The trait which can express its effect over contrasting trait is called a dominant trait. It is expressed even in the presence of one copy of an allele for a particular character in the gene, i.e., it is expressed in the heterozygous condition.

Example: Yy represents dominant trait for yellow seed colour. Seed is yellow even when single copy is dominant allele Y is present.
