Importance of DNA copying in reproduction is:-
1) It contains information about inheritance from parents to offspring.
2) It codes for proteins required by an individual.
3) If DNA is not copied during reproduction, correct proteins will not be formed and
the structure of the individual will be entirely different.
4) Errors in DNA copying will lead to evolution.
5) It makes the organism look similar to each other.
All the variations in the species do not have equal chances of survival in the environment. The survival of the variations depends upon the nature of variation.

All the variations in the species do not have equal chances of survival in the environment. The survival of the variations depends upon the nature of variation. Different individuals have different chances. Selection of variants by environmental factors forms the basis for evolutionary processes. These variations may lead to increased survival advantages of the individuals due to positive adoption of traits or may merely contribute to the genetic drift.
Trait B appears to own arisen earlier because it is gift in larger fraction of the population. Since agenesis maintain the attribute within the population and make the relation with identical traits as gift in the oldsters.

Convex mirror is preferred as a rear-view mirror in cars and vehicles as it gives a wider field of view, which helps the driver to see most of the traffic behind him. Convex mirrors always form an erect, virtual, and diminished image of the objects placed in front of it.

The mirror that can give an erect and enlarged image of an object is Concave Mirror. When an object is placed between the pole and the principal focus ,the image formed is virtual, erect, and enlarged.

The near point of the eye is the minimum distance of the object from the eye, which can be seen distinctly without strain. For a normal human eye, this distance is 25 cm. The far point of the eye is the maximum distance to which the eye can see the objects clearly. The far point of the normal humanRead more

The far point of the eye is the maximum distance to which the eye can see the objects clearly. The far point of the normal human eye is infinity.
Human eye can see objects clearly only when image is formed at retina. A person with a myopic eye cannot see objects beyond 1.2 m distinctly because, In a myopic eye, the image of a distant object is formed in front of the retina. This defect can be corrected by using a concave lens.

See lessIf a trait A exists in 10% of a population of an asexually reproducing species and a trait B exists in 60% of the same population, which trait is likely to have arisen earlier?
Trait B appears to own arisen earlier because it is gift in larger fraction of the population. Since agenesis maintain the attribute within the population and make the relation with identical traits as gift in the oldsters.

The radius of curvature of a spherical mirror is 20 cm. What is its focal length?
Radius of curvature = 2 x focal length. So, focal length = 1/2 × radius of curvature =1/2×20 cm = 10 cm
Radius of curvature = 2 x focal length.
See lessSo, focal length = 1/2 × radius of curvature
=1/2×20 cm = 10 cm
Define the principal focus of a concave mirror.
The principle focus of concave mirror is a point on its principle axis to which all the light rays which are parallel and close to the axis, converge after reflection from the mirror.
