What is science?
Some of the earliest archaeological evidence for scientific reasoning seems to be tens of thousands of years old, and science may be as old as the human species. In the period between 3000 and 1200 BCE, Mesopotamia and Ancient Egypt produced the earliest written records inside the history of science. Greek natural philosophy of classical antiquity, where formal attempts were made and provide explanations of events inside the physical world based on natural causes, was influenced by their contributions to mathematics, astronomy, as well as medicine. The knowledge of Greek worldviews declined in Western Europe during the early Middle Ages (400–1000 CE) following the fall of the Western Roman Empire, but it was preserved in the Muslim world during the Islamic Golden Age as well as later by attempts of Byzantine Greek scholars who brought Greek manuscripts from the waning Byzantine Empire to Western Europe in the Renaissance.

Why humans can't live off sunlight. Shine's experiment received alot of criticism
Answer:
Humans can't live off sunlight (among other reasons)because we don't have chlorophyll in our bodies. Chlorophyll takes the sun's energy and converts it into useable energy for plants to use. Adding energy to anything is not beneficial unless there is a mechanism to convert that energy into a useful form.

Scientific knowledge is durable yet subject to change
Science is a social activity
Scientific knowledge is a body of trustworthy new information about the world that has been gathered via experimentation and data collection.
Two points in the definition of science need to be emphasised. Science is a body of knowledge, first and foremost. It is a method by which knowledge is created, according to the second point. Therefore, a collection of trustworthy new information about the world that has been discovered through experimentation and data collection can be referred to as scientific knowledge.
All of the scientific knowledge we have is a result of our own observations. Because humans are inherently fascinated about many things in the physical world, we try to look into them and discover solutions. The process of organising and evaluating gathered data to potentially explain a phenomenon is known as scientific research. It is carried out precisely and repeatedly in order for empirical data to demonstrate the veracity of the outcomes.

Which level sets the stage for the overall productivity of an ecological
energy pyramid? Why is this the case?
Bottom level sets the stage for the overall productivity of an ecological energy pyramid.
A graphical representation of the biomass or bioproductivity at each trophic level in a given ecosystem is known as an ecological pyramid. An energy pyramid, also known as a trophic or ecological pyramid, is a graphical representation of the energy contained within an ecosystem's trophic levels. The producers are at the bottom and largest level of the pyramid, and they contain the most energy.
Environmental pyramids are useful because they graphically depict the relationship between producers and consumers. To calculate energy, content, biomass, or population, the organism at that trophic level must be estimated. A trophic level, as opposed to a species, denotes a functional level.

A. Seed shape is a non-Mendelian trait.
B. It is not an inherited trait.
C. Wrinkled seeds are recessive.
D. Seed shape is controlled by four genes.
Answer:
C. Wrinkled seeds are recessive.
Explanation:
During F1, one dominant and one recessive allele for a gene resulted in the dominant phenotype.
F2 resulted in a homozygous recessive, which refers to the genotype of an organism with two recessive alleles.
Answer:
c) Wrinkled seeds are recessive.
Explanation:
In Mendel's experiment, wrinkled seeds show up in F2 generation, even though they were not present in F₁ generation because Wrinkled seeds are recessive.
Mendel proved that 25% of the F2 generation is recessive and it cannot be seen in the F1 generation. Therefore, the option (c) is correct answer.
Explain how matter and energy interact within an ecosystem.
Provide evidence from each source to support your explanation.
As per the statement energy and matter interacts in ecosystem in following manner.
Energy flows across an ecosystem, while matter cycles within it. Let's take a closer look at how various living activities influence the movement of energy and matter in ecosystems to better understand why this is the case.
What is energy and matter?Matter is the material substance that constitutes the observable universe and, together with energy, forms the basis of all objective phenomena. Energy, in physics, is the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms.
When producers engage in photosynthesis, they draw energy from the sun and store it as chemical potential energy, which is how energy enters an ecosystem. During this procedure, environmental debris (in the form ofO2 Organic molecules are formed by ingesting O) and rearranging it (sugars). These organic molecules can either be stored as biomass or used to power the producers' biological functions through cellular respiration, which produces heat and gases.
Decomposers receive matter and energy from dead producers, consumers, and the waste they make. Matter is converted back into inorganic forms by decomposers so that it can be recycled in the ecosystem.
So, the energy that comes from sunlight entering an ecosystem eventually leaves the ecosystem as heat. As atoms are mixed and recombined in various ways, on the other hand, the matter in an ecosystem is continuously renewed.

Plants, algae and other photosynthetic organisms use energy from the sun to make their own food using the process known as photosynthesis.
Photosynthesis has two phases in which the synthesis of food is accomplished. The light-dependent reactions and the light-independent reactions. All of these occur in the chloroplast of the cell.
The light-dependent reactions actually captures the sunlight energy and convert it into the usable form of energy by plant like ATP and NADPH. The light-independent reactions then use this chemical form of energy to actually synthesize the food in the form of glucose. Thus, the sunlight energy is very essential to initiate the whole process of photosynthesis.

The hydrolytic enzymes are most likely to accumulate in which of the following cellular structures?
a. Nucleus
b. Mitochondrion
c. Smooth endoplasmic reticulum
d. Golgi Apparatus
Answer:
In principle, the lysosomes are the responsible for accumulating of hydrolytic enzymes, so if the drug did not prevent the formation of lysosomes, the accumulation of hydrolytic enzymes would be in charge of the lysosomes.
But in the statement it says that the drug with which the cell is being treated prevents the formation of lysosomes, and in this case, the organelle that is most likely to perform the function of accumulating hydrolytic enzymes is the golgi apparatus.

1.Optimization of the data analysis.
2.Sequencing the entire genome.

One of the greatest scientific achievements in history is the Human Genome Project. An international team of scientists undertook the project as a biological odyssey to thoroughly examine the entire DNA (also known as a genome) of a particular group of organisms.
What is Human Genome Project?
All of the human genes were sequenced as part of the Human Genome Project, an international research endeavor. The lengthy undertaking was started in 1990 and finished in 2003. Accurately sequencing the human genome's 3 billion nucleotide base pairs was one of the project's objectives. The identification and mapping of every human gene found in the DNA sequence was a secondary objective. (Right now, scientists believe there to be between 20,000 and 25,000 genes.) The Human Genome Project also sought to publicly archive all of the sequence data gathered in online databases.Facts of human genome project:
The Human Genome Project was a significant international scientific undertaking with the primary objective of producing the first sequence of the human genome.Over 90% of the human genome was covered by the genome sequence the Human Genome Project generated in 2003. It was as close to completion as the DNA sequencing methods at the time would have allowed.The effort was essential for advancing regulations and winning more support for the free exchange of scientific information.The sequencing of the human genome has raised concerns and problems, which has led to a heightened focus on ethics in scientific research.The project was unusual for biomedical research because the researchers' work was motivated by the desire to discover a new aspect of the biological universe rather than by developing a theory or hypothesis first.Hence this is all about Human genome project.
