I think the correct answer from the choices listed above is option C. The continent that was not covered by ice during the Pleistocene ice age. This is because the southern location of this nation made it much harder for ice to form, even during this time. Hope this answers the question.
A= U, G= C, T= A You can reverse it as well to find the codons
Loess is a geologically material which is usually yellowish or brown in color and consisting of tiny mineral particles brought by wind to the places where they now lie. It is a sedimentary deposit of mineral particles which are finer than sand but coarser than dust or clay, deposited by the wind. Loess is a type of silt which forms fertile topsoil in some parts of the world. The soil has few clay particles to hold it together. It is composed mainly of quartz crystals which slide easily against each other, and is therefore very subject to erosion.
Answer: B. The population using long sticks has mostly long sticks in its environment
Explanation:
Going back to the statement that reiterates the hypothesis after observations about the apes in the Introduction.
Reviewing the findings in this case, on the behavior of using sticks to dig seem to be the focus the experiment and choice length of the stick.
Making a judgment about whether or not the two finding has been supported is next step.
If there are equal numbers of short and long sticks in the environment of each population and the apes chooses one specific we can say their behavior is learned.
If the chimpanzees using short sticks have made the the sticks short by breaking long sticks then we can say this behavior is learned.
When the Young chimpanzees in both populations start out using sticks of many different sizes we can see that these variables of learning is yet to be perfected.
When individuals in the population that don’t use the common stick length for that population catch fewer termites this reveals a randomness in the behavior of interest.
At this point we can say that if the population using long sticks has mostly long sticks in its environment then there is a biased objective in the study and this does not support the hypothesis that the choice of stick length is a learned behavior.
Answer:
DNA packaging contributes to the compaction of the genetic material into cells that are many times smaller and also regulates gene expression and cell replication in living systems.
Explanation:
DNA is a fundamental molecule that contains instructions that make each organism unique. Each chromosome is composed of a very long linear DNA molecule associated with histone proteins that compact the genetic material, which is known as DNA packaging. Transcription and replication require that both strands of the DNA separate. Nonetheless, during DNA packaging, nucleosomes and the folding into chromatin fibers ensure chromosomal DNA is correctly packaged inside smaller nuclei. In consequence, DNA packaging not only enables the compaction of long linear DNA into the cells but also is involved in key biological processes such as gene regulation (transcription) and cell replication.
