What do does it mean to have a commercial market for space travel and what benefits could come from having one?
Answer:
The commercial market for space travel have generated multiple benefits for scientific experiments.
Explanation:
The flight of NASA astronauts onboard commercial spaceships to the International Space Station may be at risk, but the payoffs from low-cost flights to the orbital station and the increased experimental use of the microgravity environment are expected to be significant. Scientific studies, such as the production of vaccines, are now taking place onboard the space station, so providing more cost-effective means of entering earth orbit could fundamentally change other industries, such as medicinal and materials engineering.

Explanation:
5. In your everyday life, you have probably noticed that certain instruments are ideal for certain situations. For example, you would use a spoon rather than a fork to eat soup because a spoon is shaped for scooping, while soup would slip between the tines of a fork. The use of ideal instruments also applies in science. In what situation(s) would the use of a light microscope be ideal, and why
Answer:
A light microscope, particularly when the cell has indeed been spattered to disclose information, would've been ideal when examining a small living organism.
Explanation:
A light microscope is a laboratory biology instrument or device that uses transparent sensors to illuminate and exacerbate and enlarge, very small objects. Individuals use lenses to center light on the test sample, thereby amplifying it to produce an image. The experiment is usually located near the respective.
It does this by producing a magnified image using a series of glass lenses, which first focuses a laser light on or through an object, then conveys objective lenses to expand the created image.
Explanation:
A light microscope would be ideal for viewing significantly small living organisms, such as bacteria , viruses, and other single celled organisms. A microscope is device especially made to magnify the size of object or the beings. So, it helps to the study the details of the tiniest of the things.

Just considering one locus (a specific location on a DNA strand), evidence at a crime scene shows a genotype of 5, 9 STR repeats at this locus. The general population frequencies for the alleles 5 and 9 are 0.100 and 0.300, respectively. How frequent would the genotype 5, 9 be expected to be in the general population
Answer:
0.1 x 0.3 = 0.03 = 3%
Explanation:
Assuming a process of random mating in the population, it is possible to infer that the genotype frequencies will be the product of the allele frequencies. The random mating is one of the postulates of the Hardy-Weinberg Law, which is widely used in population genetics to estimate genotypic frequencies when populations are expected to be in an equilibrium state (it is also expected by default in human populations). In this case, the genotype frequencies will be certainly low (3%), thereby this locus may be useful to investigate a police case.

Suppose a team of researchers becomes the first to synthesize organic molecules out of inorganic molecules. The conditions to which they subject their samples of inorganic molecules include periods of intense sunlight and radiation followed by periods of extreme cold—temperatures near that of outer space. After many such cycles of intense energy bombardment and cold, the researchers observe the development of organic molecules. If the findings of the researchers prove to be accurate, which features of their findings might challenge the primordial soup theory? Which aspects of the primordial soup theory would need to be adjusted in light of this new evidence? Why
Answer:
Primitive Earth where life emerged was subjected to extreme conditions
Explanation:
The origin of life is still an issue of intense debate today, although most researchers believe that life emerged from primitive organisms generated by the synthesis of organic compounds in early Earth. In line with this theory, it has been shown that membrane-forming compounds can be formed in extreme conditions (i.e., UV rays, extreme temperature, etc). It is believed that such conditions recreated in a laboratory were similar to the early Earth about 3,900 million years ago, thereby supporting the idea of the 'primordial soup theory' proposed by John Burdon Sanderson Haldane in 1929.
Iodine-131, a beta emitter, is one such product of nuclear fission, extremely dangerous because it is typically produced in huge quantities and because it is incorporated in the human body in the thyroid gland. The half-life of 1311 is 8.04 days. What fraction (expressed as a decimal number) of the 1311 produced in a nuclear accident would remain after 60.0 days?
Answer:
0.00568
Explanation:
Recall that the fraction of radioactive material left after a time (t) is obtained from the formula;
N/No = (1/2)^t/t1/2
Where;
N= mass of radioactive material left after a time t
No= mass of radioactive material initially present
t= time taken for N mass of radioactive substance to remain = 60.0 days
t1/2= half-life of the radioactive substance= 8.04 days
Note that the required fraction is N/No, hence;
N/No= (1/2)^60.0/8.04
N/No= (1/2)^7.46
N/No = 0.00568

The examples of negative feedback among the given options are 1. A child whose thymus gland is building an immune system that gets stronger each day.
3. When someone's pancreas stops producing the hormone that lowers blood sugar because the person hasn't eaten recently.
4. When someone's pancreas hormone increases every time they eat but decreases when they aren't eating.
Negative feedback is a regulatory mechanism in the body that works to maintain homeostasis by counteracting or reversing changes in the body's internal environment.
It helps to keep various physiological processes within a narrow range and prevent excessive fluctuations.
1, the child's thymus gland building an immune system that gets stronger each day is an example of negative feedback. As the child grows, the thymus gland stimulates the production of immune cells (such as T cells) to strengthen the immune system, which is a response to the body's needs.
3, when someone's pancreas stops producing the hormone that lowers blood sugar because the person hasn't eaten recently, it demonstrates negative feedback.
4, when someone's pancreas hormone increases every time they eat but decreases when they aren't eating, it also illustrates negative feedback. After a meal, the pancreas releases insulin to facilitate glucose uptake by cells, reducing blood sugar levels.

Tracey knows that proteinuria (protein in the urine) after intense exercise is physiological (normal). However, protein is typically not present in urine. Why is that?
Answer:
Normally, protein should not be found in the urine. A person who has protein in the urine is said to have proteinuria.
Explanation
Strenuous exercise increases glomerular filtration of low-molecular-weight proteins (β2-microglobulin), which overwhelm the reabsorbing capacity of the tubular apparatus, causing temporary dysfunction and tubular proteinuria. Exercise-induced proteinuria is generally benign and a function of the intensity—rather than the duration—of exercise.1 It occurs most often among athletes participating in such sports as running, swimming, rowing, football, or boxing.2 It’s also transient—lasting 24 to 48 hours.1 Recognizing exercise-induced proteinuria is fairly straightforward—once you know what to look for.

Energy is released from ATP when every phosphate bond is broken. the last phosphate bond is broken. all three phosphate bonds are formed. the last phosphate bond is formed.
Answer:
the last phosphate bond is broken
Explanation:
Adenosine triphosphate, commonly known as ATP, is a high energy storage molecule. It is the form of energy usable by living cells to carry out their various life functions. ATP is synthesized in living systems during the process of cellular respiration.
ATP is a chemical compound that contains an Adenine base, ribose sugar, collectively called Adenosine, and three phosphate groups. Hence, the name Adenosine triphosphate. The stored energy in ATP is released when the bond holding the last phosphate group is broken. This releases a phosphate group and Adenosine diphosphate (ADP) molecule.

C. A prokaryote
D. A plant
Answer:
C. A prokaryote
Explanation:
A prokaryote is an organism that consists of a single cell that does not have a nucleus or membrane-bound organelles.
A prokaryote is an organism whose cells do not have a membrane-bound nucleus. Therefore, option (C) is correct.
What is a prokaryote cell?
Prokaryotes are unicellular organisms, such as bacteria and archaea, which lack many of the organelles found in eukaryotic cells, including a nucleus. In prokaryotic cells, the genetic material is contained in a single circular chromosome located in the cytoplasm, which is not separated from the rest of the cell by a nuclear membrane.
The lack of a nucleus is one of the defining characteristics of prokaryotic cells, which are distinct from eukaryotic cells found in animals, plants, fungi, and protists, which all have a nucleus and other membrane-bound organelles.
