As the number of organisms increase so does their tropic levels. As one organism eats the other energy is being transferred to that organism. The larger the food chain the lesser the organism' s would be because they would lose energy while trying to hunt and catch their prey and other activities. The food chain usually ends at the tertiary consumer or the fourth link because if it goes on like that there would be less energy hence these organisms would most likely starve and gradually die.
Two sister chromatids are held together by the centromere
<h3>The Chromosome</h3>
The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.
Each of the sister chromatids carries an allele of the same gene.
The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.

Answer:
The collisions release heat, which results in the heating and subsequent melting, sinking, and rising of materials.
Explanation:
The collisions literally release heat (kinetic energy). Energy from collision increased temperature, causing materials to melt.
I believe the polysaccharide that provides rigidity and strength in plants would be cellulose. As this is one of the essential components found in the cell wall of plant cells.
Answer:
This question lacks options, options are:
A) ATP
B) NADP
C) Pryuvate
D) glucose
E) acetyl-CoA.
The correct answer is C) Pyruvate.
Explanation:
Pyruvate is a very important compound for the cell since it is a key substrate for energy production and glucose synthesis (neo-glycogenesis), that is, pyruvate is the end product of glucose breakdown in glycolysis. Before entering the mitochondria, it can be converted to lactate, through an anaerobic reaction (in the absence or under oxygen supply) of low performance in energy production, when the main pathway is interfered with. It can also be converted to the amino acid alanine. Within the mitochondria, it can be transformed, by pyruvate dehydrogenase (PDH), into acetyl-coenzyme A (acetyl-CoA), the entry point (substrate) of the Krebs cycle. In addition, by means of pyruvate carboxylase, it can be transformed into oxalacetate, which constitutes the first step in neoglycogenesis.
