Answer:
Sister chromatids are identical copies of chromatids from chromosomes. They are typically produced through the semi-conservative replication of a single chromosome's DNA. Thus, they can be viewed as'photocopies' of the original parental chromosomes, linked together at the centromere.
They are entirely identical in every aspect, sharing the same genes and allele configurations.
Still, minor variations can occur between the identical sister chromatids due tomutations fromerrors during replication, and differences can also arise in the lengths of telomere repeats.
Non-sister chromatids differ as they arise from separate haploid sex cells during fertilization. These chromatids come from distinct parents and possess different genetic compositions since they do not lie on the same homologous chromosomes. This is why crossing-over results in genetic variation.
However, they may still exhibit genetic similarities if they are part of homologous chromosomes. This is because Synapsis of the bivalents in these chromosomes permits the exchange of genetic material through crossing-over between non-sister chromatids, thereby sharing identical genetic traits.
Explanation:
The process of photosynthesis is largely similar for plants in desert and temperate climates, with the main distinction being that desert plants absorb carbon dioxide during the night, storing it as an organic acid.
Response:
The skeletal system's bones collaborate with the muscular system's muscles.
Clarification: The system composed of muscles and bones allows for movement.
(I hope this is useful; you could also look for the same question as someone might have already addressed it.)

Carbon dioxide is produced during cement production as a result of burning fossil fuels.
