We need the options in order to answer
Answer:
Option A
Explanation:
The vestibular system is a part of the inner ear that provides the most important contribution to the sense of balance and coordinating movement with balance. This system is made up of two parts which are the three semicircular canals and the two otolith organs. The two otolith organs are the saccule and the utricle. The utricle is sensitive to changes with regards to horizontal movement and the saccule provides information about vertical acceleration. They are able to do this due to their orientation in the inner ear providing spatial orientation with regards to movement and balance. the three semi circular canals includes the horizontl, poterior and the superior semicircular canals. they provide sensory inputs.
Fossil molds and casts preserve a three-dimensional impression of remains buried in sediment. Cast fossils occur when mold fossils are filled in with minerals that harden over time, creating a fossilized replica of the original organism. Mold fossil-A fossil formed when an animal, plant, or other organism dies and is covered by sediment, its flesh decays and bones deteriorate due to chemical reactions, and a cavity remains below the ground surface.
Answer:
Nucleus (as nuclear DNA),mitochondrial(mitochondrial DNA) and chloroplasts.
DNA is packed tightly around protein called Histones, in Eukaryotes cells;so that many molecules can easily be held together as chromosomes.
Chromosomes are thread-like structure in nucleus of cells.The histones provide support to the DNA molecule
The part DNA molecule coded for by a polypeptide is GENE, therefore in the nucleus of cells, DNA contains GENE,and the gene and DNA are packed in chromosomes,DNA appears as circular DNA mitochondria
