Pros - Gets a lot of sunlight
Cons - Might get dehydrated
Answer: well they give nutrients to the body to help the human body to grow and stay healthy.
Adenosine triphosphate (ATP) is the fuel for muscle contraction. In muscle cells, ATP is used for the active transport of calcium ions (Ca2+) and the movement of motor proteins.
- The condition of skeletal muscle fatigue can be best explained by insufficient intracellular quantities of ATP due to excessive consumption.
- Muscle cells contain a high amount of mitochondria because they need to create more ATP to function than other cells.
- During skeletal muscle fatigue, ATP is resynthesized by the oxidation of carbohydrates and the anaerobic use of phosphocreatine.

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 .
