Answer:
Iodine and Sulfuric Acid.
Explanation:
During Molisch's test, Sulfuric Acid is used to judge whether or not a carbohydrate is present, and, if so, a purple ring will appear. In the iodine test, iodine is used to confirm starch is in the carbohydrate, and will alert you with a blue ring appearing.
Answer:
In the presence of starch, iodine turns a blue/black color. It is possible to distinguish starch from glucose (and other carbohydrates) using this iodine solution test. For example, if iodine is added to a peeled potato then it will turn black. Benedict's reagent can be used to test for glucose.

In maize, a meiocyte has 20 chromosomes. What will be the number of chromosomes in its somatic cell?
(a) 40
(b) 30
(c) 20
(d) 10
Answer:
20
Explanation:
Meiocytes are diploidsThey have 2n number of chromosomes.Somatic cell also has 2n no of chromosomes .so it remains same 20 chromosomesOrganisms choose to have different traits when they are struggling to survive and reproduce.
A. True! That is why the bed bugs stopped being affected by the insecticide.
B. False! Bed bugs do not choose their genes. Genes are passed on from parents and may have random mutations.
Answer:
Im not sure but i would assume it'd be false

Why are the reactions that occurred in early earth different from modern Earth?
because of the help of a living being in the form of plants/algae that enrich oxygen on earth, then after the oxygen is fulfilled, son, then living creatures such as animals, etc. will develop.
The reactions that occurred in early Earth were different from modern Earth due to several factors related to the planet's initial conditions and its subsequent evolution over billions of years.
1. Atmosphere: The early Earth had a drastically different atmosphere compared to the present one. It was primarily composed of gases like methane, ammonia, and water vapor, lacking significant amounts of oxygen. Modern Earth's atmosphere, on the other hand, is predominantly nitrogen and oxygen, with trace amounts of other gases.
2. Temperature: Early Earth was much hotter than it is now due to intense volcanic activity and the planet's heat from its formation. Over time, as the Earth cooled down, the temperatures became more conducive to different chemical reactions.
3. Surface conditions: The early Earth had a more active and geologically dynamic surface with frequent volcanic eruptions, impacting the types of reactions that could occur. Today, the Earth's surface is relatively stable and has developed diverse ecosystems.
4. Availability of elements: The abundance and distribution of elements on early Earth were different, as various geological and cosmic processes have influenced the planet's elemental composition over time.
5. Biological influence: Life itself has significantly impacted the chemical reactions on Earth. Early life forms, such as cyanobacteria, played a vital role in oxygenating the atmosphere through photosynthesis, which led to significant changes in the chemistry of the Planet.
These factors collectively shaped the early Earth's chemical landscape, fostering reactions that were distinct from those observed in the modern Earth we know today. As the planet evolved, so did its chemical and physical processes, leading to the diverse and complex environment we now inhabit.

Which of the following genotypes would represent a HAIRLESS guinea pig? *
10 points
HH
Hh
hh
Answer:
hh
Explanation:
Hairlessness in guinea pigs (or skinny pigs) is recessive, thus hh.
If you bred two hairless guinea pigs together, their offspring will always be hairless.
However, if you bred a hairless guinea pig with a regular guinea pig, their offspring will always have hair. They'll just carry the gene for hairlessness.
are SARS-CoV-2 infection and transmission study on humans rather than animal models unethical?
Answer:
No. As long as these studies are supervised by ethics committees of human research
Explanation:
In medical research, ethical committees are responsible for ensuring that experimentation and methodological studies on human subjects are carried out in accordance with national and international well-established guidelines. In general, experimentation on human subjects is framed in a line of phased clinical trials. The ethics committees are organizations composed of medical specialists, scientific researchers, non-medical and non-scientific members who work together to ensure the protection of the rights, health and safety of the human subjects involved in such clinical trials.
SARS-CoV-2 infection and transmission studies on humans instead of animal models are ethical thanks to the supervision of the ethics committees.
The answer is no, As long as these studies are supervised by ethics committees of human research.
The ethics committees are organizations composed of medical specialists, scientific researchers, non-medical and non-scientific members who work together to make sure the protection of the rights, health, and safety of the human subjects involved in such clinical trials.
Poor responses from the authorities to the spread of infection, lack of effective measures for prevention, unavailability of promising treatment options, and sufficient diagnostic options have created an alarming for the globe.
The transmission routes from human to human of SARS-CoV-2 can be-The direct transmissionDroplet inhalation transmissionContact transmissionTransmission through salivaTransmission via fecal-oral routes.
In medical research, ethical committees are responsible for ensuring that experimentation and methodological studies on human subjects are carried out in accordance with national and international well-established guidelines.
Therefore, SARS-CoV-2 infection and transmission studies on human trials are ethical so the answer is No.
