In hen internal fertilisation is there and here the chances of the young ones survival is more , but in fish the external fertilisation takes place , many eggs get eaten by big fishes and many get destroyed by extreme pressure and other conditions and only less eggs develop into adult fish and have less life span so thats why fish lay more eggs and hen lays only 1 egg.

And in hen internal fertilization takes place and the baby hatch from the egg has more survival chance as compared to those in case of a fish. Hence, hen lay only one egg and fish lay many eggs .

The case of fertilization in fish eggs is not much, so when fish lays thousands of eggs at a time , then many of them get eaten by big fishes/animals, many get destroyed due to extreme pressure and other conditions and then the few left- get fertilized and a new offspring (baby fish) is formed .

Due to f-electrons in inner cell, Shielding effect decrease which cause decrease in size from 2nd transition series to 3rd transition series....So elements of both period elements hv about same atomic and ionic radii.this is called lanthenoid contraction

Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.

Matter is everything around you. Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume).

Yes , zero displacement is possible if an object has moved through a distance. Suppose a body is moving in a a circular path and starts moving from point a and it returns back at same point after completing one revolution then the distance will be equal to its circumference while displacement will be zero.
