Introduction :
Birth rate: The number of live births per 1000 individuals of the population per year.
Death rate: The number of deaths per 1000 individuals of the population per year.
PGR (
PGR mainly depends upon Birth rate, Death rate, immigration, and emigration.

Answer to Problem 29A
Correct answer :
The correct answer is option (B) 1.6 percent.
Explanation of Solution
Explanation/justification for the correct answer :
Data given:
Birth rate: 24 in year 2004 that is 24 live births per 1000 people in 2004
Death rate: 8 in year 2004 that is 8 deaths per 1000 people in 2004
Population growth rate (PGR) = [(Births-Deaths)/1000]*100
= [(24-8)/1000]*100
= [(16)/1000]*100
= (0.016)*100
= 1.6%
Hence, PGR of Asia (excluding China) in 2004 is 1.6%.
Explanation for incorrect answer :
Option (A) 0.16 percent is the wrong answer.
Option (C) 16 percent is the wrong answer.
Option (D) 160 percent is the wrong answer.

- What is this?arrow_forwardMolecular 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?

- Molecular 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. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
