An important piece of information in the management of a person infected with a chronic virus such as HIV is his/her "viral load" or how many virus particles can be detected. If before PCR, a patient had a viral load of 1.6 x 104 viral particles. What would be the amount of DNA in the sample after the completion of the first PCR cycle?
Answers
Answer:
the answer is 3.2 x 10⁴
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology to exponentially amplify a specific DNA sample from a small amount of DNA. For this purpose, the PCR technique uses: 1- a DNA polymerase enzyme in order to synthesize new DNA copies and 2- one pair of DNA oligonucleotides (primers) which are complementary to the ends of the target DNA sequence. During each round of PCR, the double-stranded DNA template is unwound and each strand is used to synthesize a new DNA strand, thereby forming two new double-stranded DNA molecules. In consequence, each round of PCR doubles the amount of DNA.

( biochemistry )
Answers
Answer:
Hydrolysis
Explanation:
Hydrolysis is a reaction that needs water to breakdown macromolecules into simpler units.
Macromolecules are giant polymers made up of several repeating monomeric units.
These units are too complex for the body to digest and derive nutritional benefits from them. During hydrolysis, the complex is broken down into monomers. The monomeric units are absorbable and useful for the body.At the complete end of cellular repiration, how many molecules of ATP are produced? A. 15 B. 34 C. 38 D. 26
C.38
Answers
Answer:
C.38
Explanation:
During aerobic cellular respiration, one molecule of glucose is broken down in the presence of oxygen to produce approximately 38 molecules of ATP. Light energy is converted into chemical energy in the process of photostnthesis- the resulting carbohydrate moecule incorporates linorganic carbon, and water to produce oxygen and glucose.
ATP or adenosine trohosphate is a high energy molecule, used as a type of energy currency in cells. In respiration, glucose is converted to pyruvate- this molecule's derivatives are then oxidized and reduced to harvest energy as ATP.
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP
glucose+ oxygen → carbon dioxide+ water+ energy

O Terrestrial and eukaryotic
Answers
Photosynthtic and multicellular correctly describes distinguishing characteristics of the Kingdom Plantae.
What are the characteristice of kingdom Plantae?Kingdom Plantae includes all the plants. They are eukaryotic, multicellular and autotrophic organisms. The plant cell contains a rigid cell wall. Plants have chloroplast and chlorophyll pigment, which is required for photosynthesis.
They are non-motile. They make their own food and hence are called autotrophs. They reproduce asexually by vegetative propagation or sexually. These are multicellular eukaryotes.
Kingdom Plantae is broadly composed of four evolutionarily related groups: bryophytes (mosses), (seedless vascular plants), gymnosperms (cone bearing seed plants), and angiosperms (flowering seed plants).

Temperature changes led CO2 changes
Methane played the dominant role in the warming and cooling
Plate tectonics played the dominant role in the warming and cooling
CO2 changes led temperature changes
Answers
Answer:
Explanation:
The history of humanity from the initial appearance of genus Homo over 2,000,000 years ago to the advent and expansion of the modern human bieings that we are today evoled from many years ago some say from the begining of time— it is connected to climate variation and change. Human biens has experienced nearly two full glacial-interglacial cycles, but its global geographical expansion, massive population increase, cultural diversification, and worldwide ecological domination began only during the last glacial period and accelerated during the last glacial-interglacial transition. The first bipedal apes appeared in a time of climatic transition and variation, and Homo erectus, an extinct species possibly ancestral to modern humans, originated during the colder Pleistocene Epoch and survived both the transition period and multiple glacial-interglacial cycles. Thus, it can be said that climate variation has been the midwife of humanity and its various cultures and civilizations.
Answer: involve rapid, nonlinear, reactions of ice volume, CO2, and temperature to external astronomical forcing. The precise timing of events may be modulated by millennial‐scale climate change that can lead to a contrasting timing of maximum interglacial intensity in each hemisphere. A variety of temporal trends is observed, such that maxima in the main records are observed either early or late in different interglacials. The end of an interglacial (glacial inception) is a slower process involving a global sequence of changes. Interglacials have been typically 10–30 ka long. The combination of minimal reduction in northern summer insolation over the next few orbital cycles, owing to low eccentricity, and high atmospheric greenhouse gas concentrations implies that the next glacial inception is many tens of millennia in the future.
1 Introduction—Interglacials of the Last 800 ka
Earth's climate of the last 800 ka (1 ka = 1000 years) is the latest stage in a slow cooling that has been in progress for the last ~50 Ma (1 Ma = 1 million years) [Zachos et al., 2008]. During this cooling, ice sheets formed on the Antarctic continent ~40 Ma ago, while the first signs of Northern Hemisphere (NH) glaciation appeared much more recently. Only at the start of the Quaternary Period and the Pleistocene Epoch, ~2.6 Ma ago, did alternations between cold glacial periods with ice on the NH continents, and warmer intervals with little or no NH continental ice, first appear, reflected in the appearance of ice‐rafted debris

Which is the best choice for a genetic transformation: a bacterium, earthworm, fish, or mouse?
Answers
Answer:
A bacterium would be the best choice in this case
Explanation:
Bacteria are small, single-celled organisms which reproduce quickly and easily; it is made of only one cell, it reproduces every 20 minutes, it does not make people sick, it cannot survive outside the lab, etc.
Among the options given, the best choice for a genetic transformation is implemented for a bacterium. Thus, the correct option for this question is A.
What is Transformation?Transformation may be defined as a process of horizontal gene transfer through which some bacteria take up foreign genetic material (unaided DNA) from the environment. This technique was first reported in Streptococcus pneumoniae by Griffith in 1928.
The population of bacteria utilizes three techniques in order to reproduce and permits genetic variations. They are conjugation, transformation, and transduction. Bacteria are small, single-celled organisms that reproduce quickly and easily in nature.
Transformation is the genetic alteration of a cell resulting from the direct uptake and incorporation of exogenous genetic material from a surrounding atmosphere.
Therefore, the best choice for a genetic transformation is implemented for a bacterium. Thus, the correct option for this question is A.

What is Hemoglobin?The amount of hemoglobin in your blood can be measured using a hemoglobin test. Red blood cells include a protein called hemoglobin, which distributes oxygen to your body's organs and tissues while returning carbon dioxide to your lungs.
A low red blood cell count indicates a low hemoglobin level, which can be determined by a hemoglobin test (anemia). Vitamin deficiencies, hemorrhage, and chronic disorders are just a few of the numerous potential causes of anemia.
If a hemoglobin test reveals a higher-than-normal level, there are a number of possible explanations, including the blood condition polycythemia vera, high altitude living, smoking, and dehydration.
