The chromosome number of the four resulting gametes with respect to the normal haploid number shows <u>n + 1; n + 1; n - 1; n - 1</u> <u>(option A)</u>.
During aligning of all the homologous chromosomes, in the process of meiosis, new cells are formed.
From the total number of chromosomes one chromosome is missing , the resulting chromosomes are +1 and -1. Similarly for the second cell, resulting chromosomes would be +1 and -1.
This makes four gametes i.e. -1 and -1 and +1 and +1 respectively.

The pyramid of numbers only compares the number of organisms present in each trophic level at A PARTICULAR TIME. This pyramid can be inverted if organisms of one trophic lvl is parasitic on organisms of another trophic lvl. or when threre are many small organisms feeding of one trophic level feeding on a large organism of anoyher trophic lvl.
For eg. tree→aphid →protozoa, the pyramid of numbers is upside down
however pyramid of energy is always in a pyramid shaped as it compares the total energy in each trophic level OVER A PERIOD OF TIME. more energy is lost when we mive along a food chain hence the shape is ALWAYS pyramid.
Answer:
b. starch
Explanation: starch is the end product of carbohydrate that is made up of two molecule; amylose and the amylopectin.
Macromolecule are large molecule consisting of a long chain of monomers that are joined or linked together. examples include protein,nucleic acid,amino acids.
