In glycolysis ____
is oxidized, and ____ is reduced.
A) Nad+....glucose
B) glucose.....Nad+
C) ATP.......ADP
nadph and atp are two molecules produced during the light-capturing reactions of photosynthesis. what are these molecules used for later in photosynthesis in the calvin cycle?
Given the characteristics of the Calvin cycle, we can conclude that NADPH and ATP will be used to reduce carbon dioxide to sugar.
The Calvin cycle is known as a light-independent reaction, meaning it can occur during the dark phase of photosynthesis. It is often called the carbon reduction cycle, given that it does just that. In this cycle, carbon is reduced into a sugar known as G3P. In order to do this, it requires NADPH and ATP.
As with most reactions at a cellular level, it requires ATP. This molecule is that of Adenosine triphosphate and is often known as the "molecular currency" given how common it is as a requirement for reactions to take place. ATP is the source of energy for the Calvin cycle.
Meanwhile, NADPH is also required for the Calvin cycle. The main function of the Calvin cycle is to reduce carbon dioxide through a series of steps in order to produce G3P. In order to reduce CO2, hydrogen atoms are necessary. NADPH acts as a carrier of these hydrogen atoms, offering the ions needed for the reduction to take place.

Describe the genetic components of the genetic material containing two variants of each chromosome pair, one from each parent. Give an example of the inputs and outputs of mitosis.
Answer:
Human cells contain two sets of chromosomes, one set inherited from each parent. Each cell normally contains 23 pairs of chromosomes, which consist of 22 autosomes (numbered 1 through 22) and one pair of sex chromosomes (XX or XY). However, sperm and ova normally contain half as much genetic material: only one copy of each chromosome. Each chromosome contains many genes, the basic physical and functional units of heredity.

How does refrigeration of food prevent it from spoilage?
Refrigeration preserves food by slowing down the growth and reproduction of microorganisms as well as the action of enzymes which cause food to rot. Freezing food slows down decomposition by turning residual moisture into ice, inhibiting the growth of most bacterial species.

which part of electromagnetic spectrum drives the photosynthetic process in plants?
Answer:
visible ligth
Explanation:
Visible light ranges from low blue to far-red light and is described as the wavelengths between 380 nm and 750 nm, although this varies between individuals. The region between 400 nm and 700 nm is what plants use to drive photosynthesis and is typically referred to as Photosynthetically Active Radiation (PAR).
Which of the following was developed following Griffith's 1928 experiment. A. Some pathogenic bacteria cannot be heat-killed. Bacterial virulence is related to temperature resistance. B. Streptococcus pneumoniae causes disease. C. DNA from dead encapsulated bacteria can transform living un-encapsulated bacteria into living encapsulated bacteria. D. Dead encapsulated bacteria can cause disease.
Answer:
I believe A is the answer, but I'm not positive.
Explanation:
Griffith demonstrated in 1928 that the ability to synthesis a capsule and consequently become virulent can be transferred from heat-inactivated “smooth” strains to surviving but avirulent “rough” strains of S. pneumoniae. Therefore, option (A) is correct.
What was Griffith's experiment?British bacteriologist Frederick Griffith's 1928 bacteria experiment was the first to demonstrate the "transforming principle," which led to the realization that DNA serves as the carrier of genetic information.
Griffith tried injecting mice with heat-killed S bacteria as part of his investigations (that is, S bacteria that had been heated to high temperatures, causing the cells to die). Unsurprisingly, the mice were not harmed by the heat-killed S bacterium.
The first study demonstrating that bacteria are capable of transferring genetic information through a process known as transformation was conducted by Frederick Griffith.

approximately how many nucleosomes are required to organize this region of dna into the 10nm fiber structure?
Answer:
Answer is 512 nucleosomes.
Explanation:
DNA is the genetic material that is compressed and stored in the nucleus of the cell. Approximately 512 nucleosomes would be required to organize 92,672 base pairs long region.
What are nucleosomes?Nucleosomes are the packaging units of the genetic material that comprises the DNA segments wrapped along with the histone proteins in a compacted manner. This allows the genetic material to be condensed into smaller volumes.
Given,
Genome size = 92,672 base pairs
Linker DNA = 35 bp
The total number of base pairs = number of base pairs in nucleosome core + linker DNA
= 146 + 35
= 181
The number of nucleosomes can be calculated as:
Nucleosomes = Genome size ÷ total number of base pair
= 92,672 ÷ 181
= 512
Therefore, there are 512 nucleosomes are present in the Drosophila.

Explain how Earth's magnetic field is generated.
Answer:
The magnetic field is generated by electric currents due to the motion of convection currents of a mixture of molten iron and nickel in the Earth's outer core: these convection currents are caused by heat escaping from the core, a natural process called a geodynamo.
Answer:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet

What is protein?
Proteins are among the most prevalent organic molecules in biological systems and have a much wider range of structural and functional variations. Many thousands of proteins, each serving a different purpose, can be found in a single cell.
All proteins are composed of one or more chains of amino acids, despite the fact that their structures and activities differ substantially from one another.
In biological reactions, enzymes function as catalysts, accelerating the reactions. Each enzyme may distinguish between one or more substrates, or the molecules that act as the catalysts for the reactions they catalyze.
Therefore, Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.
