Explain the relationship between homologous chromosomes and the relationship between sister chromatids. how are these relationships different from one another?

Homologous chromosomes are similar in size and shape. they have the same genes and originate from different parents. Sister chromatids are found in replicated and contain exact copies of the single double helica; molecule of DNA.

Actually homologous chromosomes can be defined as the chromosomes same in shape and size, and carry the genes of contrasting chaacteristics..Chromatids whic separate in metaphase of cell division are sister chromatids.

i am positive it is c. condensing but i may be wrong

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
