Answer:
a) this means that his weight was 25% more than baby boys his age and 75% less than baby boys his age. He's in the low percentage of weight and his weight is smaller compared to a large percentile of other baby boys.
b) at 8 months old. Where most baby boys' weight would be more than 8 kg and his is barely over 6 kg. This shows that the estimated increase of atleast 500g weight of a baby is not displayed by his chart and it shows he's undergrowth.
A) DNA 1 by chromosomal mutation
DNA 2 by genetic mutation

Answer:
One type of cell that is similar to parent cell.
Explanation:
The cells undergo cell division either by mitosis and meiosis. The meiosis produces four genetically dissimilar daughter cells as the process undergoes recombination event which exchanges the genetic sequence.
The process of recombination does not take place in the mitotic division and also the daughter cell exhibit the same number of chromosome.
In the given question, since the cell with the genotype Aa Bb Cc undergo mitotic division, therefore, the daughter cell will be produced with the same genetic material and no genetically different cells.
Thus, One type of cell that is similar to parent cell is correct.
Answer:
Quorum sensing.
Explanation:
Quorum sensing may be defined as the phenomena by which the bacteria can detect the specific stimuli and respond towards the cell population density. This process helps in coordinating gene expression.
Quorum sensing is used in prokaryotes for the cell to cell signalling and cell communication as well. The main evolution of quorum sensing in bacteria was to relay the information and helps in cell signalling by releasing the specific toxins. From the evolutionary point, the organism that are capable of quorum sensing would survive more in their environment, adapt well in their environment.
Thus, the answer is quorum sensing.
Answer:
A geneticist has devised a strategy to study protein translocation into the endoplasmic reticulum (ER) in yeast cells. She is interested in two different signal sequences that are thought to operate via slightly different translocation mechanisms. Using genetic engineering, she has fused the first signal sequence to a protein whose cytosolic expression is absolutely necessary for cell survival in the selective medium, but is inactive when in the ER. In the same cell, she has also fused the second signal sequence to a toxic protein whose cytosolic expression leads to cell lysis but is harmless when in the ER. Whereas wild-type cells undergo lysis upon the expression of these fusion proteins, she has been able to identify viable mutants, each of which has a loss-of-function mutation in a gene encoding a protein involved in membrane translocation. The products of these genes are probably ...
Explanation:
Involved in the transport of proteins with the first signal sequence but not the second one.
