Option A. Since the process of photosynthesis makes new energy, the combined energy in the bonds of O₂ and C₆H₁₂O₆ is greater than that in the bonds of CO₂ and H₂O.
In plants, carbon dioxide enters the indoors of a leaf thru pores referred to as stomata and diffuses into the stroma of the chloroplast—the web page of the Calvin cycle reactions, in which sugar is synthesized. These reactions also are referred to as the mild-independent reactions due to the fact they may be now no longer immediately pushed via way of means of mild.
In the Calvin cycle, carbon atoms from are fixed (included into natural molecules) and used to construct three-carbon sugars. This method is fueled via way of means of, and based on, ATP and NADPH from the mild reactions. Unlike the mild reactions, which take location withinside the thylakoid membrane, the reactions of the Calvin cycle take location withinside the stroma (the internal area of chloroplasts).

What is the human genome project and its purpose?
Answer:
it's an ambitious research effort aimed at deciphering the chemical makeup of the entire human genetic code
Explanation:
purpose : to accurately sequence the 3 billion nucleotide base pairs in the human genome. A second goal was to map and identify all of the human genes present in the DNA sequence.
ORRR
1.Optimization of the data analysis.
2.Sequencing the entire genome.
3.Identification of the complete human 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.

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.

Science cannot answer questions about what people should do. best describes the limits of science.
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.

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.

Why is cyanide a universal poison effective in all organisms with mitochondria?
Answer:
For every organism where mitochondria act as a powerhouse of a cell, ATP that is Adenosine Tri Phosphate is produced during aerobic respiration (i.e respiration that takes place in presence of oxygen). Cyanide interrupts this chain thus ATP production staggers which will further weaken the mitochondria and will bring metabolic reactions to an end.
Cyanide is a deadly poison that can disperse itself so fast that it can dispense throughout the body in a matter of seconds as it prevents the cell from the usage of oxygen.
Cyanide is a deadly poison that can disperse itself so fast that it can dispense throughout the body in a matter of seconds as it prevents the cell from the usage of oxygen.

Answer:C
Explanation:
Bat activity can be affected by artificial lighting. Because bats often rest during the day and hunt at night, they use their sense of hearing to help locate prey in the dark. A hunting bat emits high-pitched sound waves that reflect off insects. The external structure of the bat′s ear, which is composed of cartilage, funnels the reflected sound waves to the inner ear. The bat′s brain then identifies the location of an insect based on the amount of time it takes for the reflected sound waves to reach the bat′s ears. A group of researchers set up a study using white, green, and red lights in an otherwise dark natural habitat. The researchers measured the activity of two types of bats by recording the number of times a bat passed by. The researchers took measurements for five days in both early summer and late summer for four years.
Use the information above to determine which systems interact with each other when a bat hunts. Select the two correct answers.
A)The bat′s nervous system tells the bat where its prey is located.
B)The bat′s muscular system allows the bat to fly and catch the prey.
C)The bat uses its respiratory system to produce sounds.
D)The bat can use its skeletal system to produce sounds and locate prey.
E)The bat can use its nervous system to fly and catch prey.

6. Phenylketonuria (PKU) is an inherited disease determined by a recessive allele. If
a woman and her husband are both carriers, what is the probability of their
offspring having phenylketonuria?
Answer:
25%
Explanation:
Phenylketonuria is inherited as autosomal recessive trait . Since both the woman and her husband are the carrier of the disease their genotype would be Aa , where A is the dominant allele and a is recessive.
We can make a Punnet square as ,
[tex]\boxed{\begin{array}{c|c|c} \sf{ } & \sf A &\sf a \\\\ \sf A & \sf AA &\sf Aa \\\\ \sf a & \sf Aa &\sf aa \end{array}}[/tex]
From this , we can see that only one offspring would receive both the recessive allele and would be affected from the disease.
Hence the probability of their offspring of having PKU will be ,
