These sub units collectively ensure the process of  translation of protein my ensuing the correct  synchronisation of condoms not he smaller nit of ribosomes with the anti codons on the tRNA with the  to give a designated protein.

Therefore if there is mutation -deletion or substitution  in the codons and anti codons,.this may affect bring frame shift which affects the protein translated leading to  wrong protein formation.

Mitochondria is the organelle that gives the sperm  power to swim.Therefore the protein that  codes for mitochondrial is faulty and this affects the the tail from swimming properly.since ribosomes is the source of protein this is the correct answer

Angiosperm are plants which is known for flowering plant on the earth. The flower is reproductive parts of the angiosperm plant. They are including 4 basic parts of the flower: Carpel, Stamens, Sepals and Petals.

During angiosperm plant reproduction, 2 structure are formed which are known as the Endosperm and a Zygote. Later a Zygote will grow and form a embryo and the endosperm is known for food source of plant embryo. Endosperm and Zygote forming process is known as double fertilization and it is a unique process found in angiosperms.

Steps involved in double fertilization are:

1) The pollen tube processing to release 2 sperm cells into an unfertilized ovule.

2) When one sperm cell fuses with the eggs to the formation of zygote and another sperm fuses with the 2 polar nuclei to the formation of endosperm this process is known as double fertilization.

3) After the completion of double fertilization, a fruit and seed develop.
