Figure 1.8 Which of the following statements is false?
A. Tissues exist within organs which exist within organ systems.
B. Communities exist within populations which exist within ecosystems.
C. Organelles exist within cells which exist within tissues.
D. Communities exist within ecosystems which exist in the biosphere.

Introduction:
Biological organization is a definite series of biological structures and systems that defines life. In it, each level represents the organizational complexity. Every level is termed as the object, and each object is composed of the previous level's object.
Answer to Problem 1ACQ
Correct answer:
Among the answers given, the correct answer is option (b), communities exist within population which reside in the ecosystems.
Explanation of Solution
Explanation/justification for the correct answer:
Option (b) is communities exist within population which resides in the ecosystem. Many populationtogether form the communities. So, communities do not form the population, but populations form the communities. Further, ecosystem is composed of many communities not of populations. Hence, this option is correct.
Explanation for incorrect answer:
Option (a) is tissues exist within organs which exist within organ system. The living body is composed of many organs which together forms the organ system. Further, the organs are composed of various tissues. So, tissues form the organs and organs in turn forms the organ system. hence, this option is incorrect.
Option (c) is organelles exist in cells andthey form the tissues. Cell is the fundamental unit of the life. Cell contains many organelles in its cytoplasm and their function is to maintain life by processing metabolism. Many cells then form the tissues. Hence, this option is incorrect.
Option (d) is communities form the ecosystem which exist in biosphere. Different communities come together to form the ecosystem. Many ecosystems combine to form the biosphere. Hence, this option is incorrect.
Option (b), communities exist within population which reside in the ecosystems, is the correct answer.

- Molecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA? Thank youarrow_forwardMolecular Biology Question Explain why the cell doesn’t need 61 tRNAs (one for each codon). Please help. Thank youarrow_forwardMolecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB.
