Homework Answers
First Question
The answer will be binary fission.
Explanation: Bacteria reproduce by asexual reproduction method. Binary fission is a type of asexual method in which a single cell of bacteria divides into two identical daughter cells.
Second question
Homologous chromosomes are a pair of chromosomes that have similar structure, length & centromere position. Though they have similar types of genes but they are not genetically identical as one chromosome of the homologous pair is come from male parent & the other is come from female parent.

Time it takes for a particular type of biological cell to divide into two cells is believed to follow a bell-shaped distribution with a mean of 30.2 minutes. In a lab study of 22 such cells, the average time to divide was 28.2 minutes with a standard deviation of 3.5 minutes. Does the study provide sufficient evidence to conclude that the mean division time for such cells is less than 30.2 minutes? Round to 3 decimal places if necessary. You...

Evaluate the statements below and determine which is the BEST
reason that bacterial cells use operons and polycistronic RNA.
Initiation of all genes in a biochemical pathway are regulated simultaneously. O operons are more stable than structural genes that are located singly on a chromosome. Bacterial cells have small genomes that cannot accommodate large numbers of regulatory regions. nscribing gene 0 Bacterial genes are very short, so RNA that is not polycistronic might be mistaken for fragments that should be...

The time in minutes taken by a biological cell to divide into two cells has a normal distribution. When a sample of twenty-nine cells were observed, the mean time taken by them to divide into two was 31.1 minutes with a standard deviation of 3.7 minutes. At α = .01, test the claim that the true mean time is 30 minutes.

When the same chromosome is compared between two different cells, regions of heterochromatin and euchromatin are found in different locations between the two cells. Why does the state of chromatin packaging differ along the length of the same chromosome in two different cells?
