The stage where the doubling time will be the shortest will be the one where replication is taking place the fastest. This phase is known as the exponential phase. This phase is characterized by exponential growth rates of a bacterial colony.
This phase occurs due the excess amount of resources that are present compared to the amount necessary to sustain the bacterial colony. Therefore, not being limited by resources, the bacteria multiply rapidly. However, the resources then run out due to which replication stop, bringing on the lag phase. Finally, the bacteria begin to starve and die off due to the lack of resources, bringing about the death phase.
The set of species derived from one common ancestor.
To build phylogenetic trees, a variety of data can be employed, including genetic information, mitochondrial DNA sequences, ribosomal RNA genes, and any relevant genes, as well as morphological information such as structural characteristics, organ kinds, and specific skeletal arrangements
<h3>What is a Phylogenetic tree ?</h3>
A phylogenetic tree, also called a phylogeny, is a diagram that shows the evolutionary branches from which various species, creatures, or genes have descended from one another.
- A phylogenetic tree can be used to track a species' evolutionary history back via the tree's branches and find their common ancestors along the way.
- A lineage may preserve some of its ancestors' characteristics over time, but it will also change over time to accommodate the environment.

Hello again!
One limiting factor is the climate changes that the mammoths faced. They “stressed the mammoth population”
Another could be the humans as they arrived, the mammoths had gone extinct
Lastly the mammoths needed a lot of space as they were very big.
Hope this helped
Physical science deals with lens for cameras and binoculars.
Explanation:
Physical science is a branch of science that deals with the study of intimate natural objects such as it includes physics, astronomy and chemistry related subjects.
A lens is a transparent material that refracts light rays so that image can be formed. A lens has two curved surface which are made up of plastic or glasses which are concave and convex in nature. A converging lens is used to produce images.
Thus Nancy is dealing with physical science as she designs lens for binoculars and cameras.
For question number 1, there is one phenotype only with homozygous allele which are recessive and dominant of both parents. For question number 2, the answer is letter B. plants with both red and blue flowers because it is codominant so the trait will express both alleles. For question number 3, the answer is letter C. four genetically identical cells because it is from two daughter cells which undergo meiosis that results into 4 identical cells that are needed for somatic cells in our body. For question number 4, the answer is the leading strand is copied in the 5’ to 3’ direction and the lagging strand is copied in the 3’ to 5 because it is based in the ends of each nucleotides that is carrying the genes. For question number 5, the answer is gene regulation which is used by cells to increase of decrease specific gene products or RNA.
