The correct answer is (B) chemosynthesis and marine snow are the two ways that organisms on the bottom of deep sea food chains acquire energy.
What is the meaning of chemosynthesis and marine show?
Chemosynthesis is the utilization of energy supplied by inorganic chemical processes to make food in bacteria and other organisms. To generate a sugar, all chemosynthetic organisms require energy provided by chemical processes, although various species employ different methods.
Marine snow is a shower of biological particles that falls from the upper ocean to the deep sea. Marine snow refers to biological material that descends from higher in the water column. Some flakes fall for several weeks before reaching the ocean floor.

Explanation:
The femur is the single bone of the thigh. The patella is the kneecap and articulates with the distal femur. The tibia is the larger, weight-bearing bone located on the medial side of the leg, and the fibula is the thin bone of the lateral leg. The bones of the foot are divided into three groups.
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 .
