Answer:no. In nature, some plants and single-celled organisms, such as bacteria, produce genetically identical offspring through a process called asexual reproduction. In asexual reproduction, a new individual is generated from a copy of a single cell from the parent organism.
Natural clones, also known as identical twins, occur in humans and other mammals. These twins are produced when a fertilized egg splits, creating two or more embryos that carry almost identical DNA. Identical twins have nearly the same genetic makeup as each other, but they are genetically different from either parent
Gene cloning produces copies of genes or segments of DNA. Reproductive cloning produces copies of whole animals. Therapeutic cloning produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues.
Gene cloning, also known as DNA cloning, is a very different process from reproductive and therapeutic cloning. Reproductive and therapeutic cloning share many of the same techniques, but are done for different purposes.
Explanation:
Latitude is a geographical coordinate that is used to locate the north and the south position of a location on the earth's surface.
Explanation
- Latitude can be defined as an angle that varies from 0 degree at the equator to 90 degree at the poles.
- Latitude affects the temperature of the earth in the following ways :-
- As a person moves away from the equator the temperature of the regions away from the equator falls this is because the region receives less sunlight.
- The shape of the earth is not round it is spheroid that is the reason all the regions on the surface of the earth do not receive the same amount of sunlight.
From the above given options the 2 correct choices are
- Latitude determines the duration of the day:The areas at the equator (i.e at 0 degree latitude) the length of the day is said to be 12 hours,now as the latitude increases to 80 degree (i.e at the polar circles) the length of the day increases to 24 hours or decreases to zero.
- Latitude creates Polar and temperate zones:There are three types of latitude zones-Arctic,temperate and tropic zone.Latitude is considered as an important parameter in the classification of zones as it correlates to the amount of sunlight a region receives.

Immotile flowering plants accomplish fertilization with the help of Insects and other pollen from organisms that carry pollen to other flowers.
Explanation:
- The transfer of pollen from anther to the stigma of flower is called pollination.
- Pollination is of two types: a) Self pollination b) cross-pollination
- Transfer of pollen from anther to the stigma of same flower or flower of same plant is called self pollination.
- Transfer of pollen from anther to the stigma of different plant is called Cross-pollination.
- Pollination is the process by which angiosperms carry out sexual reproduction.
- Since, plants are immobile they need some agents for pollination like, <u>insects birds, wind, water etc </u>
