While studying the cells of a newly discovered fungus, you notice that it's organelles resemble those of most eukaryotes, but some of their shapes are a little different. Although you're pretty sure you can identify each organelle, you analyze its chemical composition just to make sure. One organelle is shaped like a ball, and it is composed of proteins, membranes, and nucleic acids. That organelle is most likely the .A) nucleus
B) endoplasmic reticulum
C) chromosome
D) Glogi body
E) lysosome

Explanation:

1. Nucleus is a ball like structure which is found in the  center of the cell only in eukaryotic cell,  true nucleus is absent in prokaryotes.

2. Nucleus contains nucleic acid and is have double membrane which contain pores though which transport of molecules occurs.

3. DNA replication , transcription and RNA splicing occur in the nucleus.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
