Explanation:
Eclipse occurs when the shadow of planetary body is cast on another body. This makes part of the planetary body where the shadow is cast to experience darkness.
- Solar eclipse occurs when the moon comes between the sun and the earth.
- This causes the shadow of the moon to be cast on the earth.
- Since the moon is smaller than the earth and the earth is spherical in shape, some part of the earth will experience the eclipse.
- Other parts facing the sun will have daylight normally.
- Not all parts of the earth faces the sun at all times due to the shape and rotation of the earth on its axis. Only the part facing the sun and where the moon shadow falls will experience the eclipse.
- The moon is also smaller than the earth and the sun and so its shadow cannot cover the whole earth. It cannot perfectly obstruct light from falling on earth.

Answer:
How cloning works: In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed. ... This young animal is referred to as a clone.
Basics of cloning:
Isolation of target DNA fragments (often referred to as inserts)
Ligation of inserts into an appropriate cloning vector, creating recombinant molecules (e.g., plasmids)
Transformation of recombinant plasmids into bacteria or other suitable host for propagation.
Screening/selection of hosts containing the intended recombinant plasmid .
Explanation:
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 respirationoxygen is combined with hydrogen to form water.
