would occur if we were suddenly thrown back into the “Dark ages” with no use of technology
Answers
So there are a lot of people who say that the Dark Ages, lasting about 1,000 years, set humans back technologically. However, some say that since the Dark Ages really only affected Western Europe, and not the Middle East or Asia, it wouldn't make a difference.
If there had been no "Dark Ages" there would have been no Renaissance. Historians actually argue about when Renaissance started, and the answer is than it is not possible to pinpoint a date. The Crusade did more to bring the eastern world to western Europe than they did to divide.

Answers
Answer:
C
Explanation:
Scientists use computer models to study complicated events and to
a. perform experiments
b. state theories
c. change theories and laws
d. make predictions
Answers
Answer:
The correct answer is - d. make predictions.
Explanation:
Computer models are scientific models that help in analyzing complex systems. Scientists use these to analyze data and on the basis of these data computer models are able to predict the outcome of the problem or can tell what will happen in the future.
These are very helpful in complex systems and are made on the basis of the data collected and are the basis of the models. Weather forecast can be predicted on the provided data.
Several human populations spread throughout the Sahara desert have multiple mutations in Gene R that confers heat tolerance. Independently, a small population of humans in the Mojave desert of California have a unique mutation in Gene Z that also confers heat tolerance. The evolution of adaptation of heat tolerance across all of these populations would be considered an example of _________
Answers
Answer:
Variation
Explanation:
Migration into a population from other populations with varying gene frequencies, evolution, or adaptation of heat tolerance is a cause of variation. The allele frequency of the resulting hybrid population would be right in the middle of its original value and the donor population's frequency. In tropical and subtropical ecosystems (Sahara deserts), high temperatures are a significant restriction to human population productivity; they induce morphological and physiological modifications at all times, resulting in significant yield losses but the ability and evolution of human species to cope in this region is as a result of variation.

Approximately 55%of an adult female body weight is water if a woman body contains 38 kg of water what is the woman's total weight
Answers
Answer: 69kg
Explanation:
Let the total weight of the woman be represented by x. Based on the information given, we can derive an equation which will be:
55% of x = 38kg
55/100 × x = 38kg
0.55 × x = 38kg
0.55x = 38kg
Divide through by 0.55
x = 38kg/0.55
x = 69.09099
x = 69kg
Therefore, the woman's total weight is 69kg.
An experiment similar to the 1952 Hershey and Chase experiments was done in which radioisotope 35S was added to a bacteriophage replicating within its bacterial host. The new phage particles were carefully isolated and used to infect fresh bacterial cells and no radioisotopes were utilized. Based on this information, where would you expect to find the 35S radioisotope immediately after infection
Answers
Answer:
inside the phage ghosts outside the bacterial cells.
Explanation:
According to Hershey & Chase- Experiments, the radioisotope 35S is frequently associated with protein since sulfur is a protein component. The radioactive sulfur is absorbed into the protein coat because it already contained sulfur (35S). The radioactive marker 35S was integrated into the Bacteriophage protein coat and remained as phage ghosts outside the bacterial cells.

Eukaryotic organisms are species that have defined nucleus and membrane limited organelles. Total 11% or 250,000 are described while 97% or 8490000 are yet to be described.
What is the population of the eukaryotes?Eukaryotes are the largest and the most dominating species that includes kingdom plants, animals, fungi and protists. A total of 8.74 million eukaryote species on Earth are present from which only 250,000 are described.
Eukaryotes are the species that are well-defined organisms that contain the genetic material enclosed within the nuclear membrane and the organelles are also enclosed.
With new discoveries and findings, many new species are described that are grouped into one of the kingdoms based on their properties and features.
Therefore, 8.74 million eukaryote species are present on Earth.

Explanation:
1. DNA
2.A , G , C and T
3.The 3-dimensional double helix structure of DNA, correctly elucidated by James Watson and Francis Crick. Complementary bases are held together as a pair by hydrogen bonds.
4.Chargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA.
5.Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.
6. 1869
7.The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.
8. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
9. A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. ... Every person has two copies of each gene, one inherited from each parent.
10. 20
11. A group of disorders that cause red blood cells to become misshapen and break down.
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anaemia) and can block blood flow causing pain (sickle cell crisis).
12. Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin).
13. The Human Genome Project was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying and mapping all of the genes of the human genome from both a physical and a functional standpoint.

Your student is trying to create a "Gene X" knockout mouse by introducing a recombinant construct into embryonic stem (ES) cells, selecting transformants, and introducing the transformed cells into mouse blastocysts. He designed his construct as follows: NeoR region of homology to Gene X---HSV tk--- region of homology to Gene X where Neo is the neomycin-resistance gene and HSV tk is the Herpes Simplex virus thymidine kinase gene. He transforms the ES cells and exposes them to G418 and ganciclovir. Explain to your student why he failed to recover transformed ES cells. Choose the two correct statements. a. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be sensitive to ganciclovir and neomycin, and would die.
b. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be resistant to ganciclovir, but sensitive to neomycin, and would die.
c. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to ganciclovir, but resistant to neomycin, and would die.
d. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to neomycin and ganciclovir, and would die.
e. His construct incorporated into the mouse DNA by homologous recombination. These cells would be sensitive to neomycin, but resistant to ganciclovir, and would die.
f. His construct incorporated into the mouse DNA by illegitimate recombination. These cells would be resistant to neomycin, but sensitive to ganciclovir, and would die.
