Answer:

Option d, a 2-base deletion

Explanation:

In a frame shift mutation, number of base (in a multiple of three) gets deleted. When a single nucleotide is lost, the gene loses its important function.

However, when nucleotide bases are lost in pair of three (as codon) or in some number which are multiple of three such as 6, 9, 12 etc. a gene still has the ability to restore is vital function.  

Hence, option d is correct.

Answer:

This is a well conserved sequence.

Explanation: BLAST a way to match or align a string of DNA or protein sequence to those that are already in a database. The way that this is done is by using statistics carefully to calculate the significance of the match. The BLAST result will produce 4 categories Max Score, Total Score, Query cover, E-Value Percent Identity. The Accession will indicate database of the sequence. In this Sequence: AAGACCCGCCGGGAGGCAGAGGACCTGCAGGGTGAGCCAACCGCCCATTGCT covers over 98.08% identity to the coding sequence (cds) of insulin. This sequence appears to be in a conserved region for many of the listed organism. This suggest that this part of the coding sequence for this protein is highly conserved

Predict how an unusually prolonged drought might affect a biological community
erik [133]

Primary consumers (such as grazers and browsers) of the biological community will put pressure on the primary producers (these are plants) since the primary producers have limited resources (water) to reproduce due to the drought. The primary producers hence become scarce and cause the primary consumers to compete for limited resources. This causes the primary producers to reduce in population. Reduction in their population causes limited resources for secondary consumers and this cascades up the food web to tertiary consumers.
