Hey, i don’t see the diagram if you repost the question i will be able to help
I had to look for the missing options of this question and here is my answer:
Osteocyte is the term that describes the cells of the bone. These cells are formed in the mesenchyme. Once the bone matures, the processes then take place inside the Lacunae and the Canaliculi, respectively. Therefore, we can say that the structure that allows the provision of nutrients and removal of wastes from osteocytes would be the canaliculi.
Answer: what are the options?

Answer:
Population (No) Population (Nt)
20,000,000 20,820,000
20,820,000 22,000,000
22,000,000 23,735,000
23,735,000 25,843,000
25,843,000 28,183,000
Explanation:
The change in Gilders population could include factors like prosperous economy and improved healthcare. This is due to the fact that as the birth rates increase the death rates decrease. Improved healthcare has slowed down the death rate. Secondly, the prosperous economy contributes to amount of immigrants coming in and out of this country.
Answer:
<u>Sister chromatids are identical forms of chromatids of a chromosomes. They are mostly formed by semi-conservative replication of DNA molecule of a single chromosome.Thus they are like </u><u>'photocopies' </u><u> of original parent chromosomes; joined together at the Centromere</u>.
They are exactly similar in all ramification; with the same gene and allele compositions..
<u>However; slight differences arise between the two identical sisters due to </u><u>mutation</u><u> from</u><u> errors </u><u>at replication;and also in the length of telomere repeats.</u>
Non-sister chromatids are dissimilar forms of chromatids of a chromosomes formed when each half of a chromosome at fertilisation from separate haploid sex-cells, of each parent. fused.They contain different genetic composition;because they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.
<u>However, they are genetically similar in composition; if they are contained in homologous chromosomes</u>. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by chromosomal crossing-over between the non-sister chromatids on the chromosomes ; therefore identical genetic characteristics are shared .
