In this equation for photosynthesis, what happens to the second reactant in the photosynthetic process? 6CO2 + 6H2O → C6H12O6 + 6O2


Carbon dioxide is broken down in the Calvin cycle.


Water is split to drive NADP to NADPH conversion in the Calvin cycle.


Glucose is formed right after the Calvin cycle.


Oxygen is released as a gas after water is split.

Answers

Answer 1

Answer: The correct answer is- Oxygen is released as a gas after water is split.

Photosynthesis is a process by which green plants and animals synthesize their own food using CO₂ ( carbon dioxide) and H₂O ( water) in the presence of sunlight. It is divided into two phases that is light dependent ( occurs in thylakoid membrane of chloroplast) and light independent phase ( occurs in stroma of chloroplast)

In the first phase, energy from sunlight gets converted to chemical energy that is ATP and NADPH and water is splitted into electrons, protons and molecular oxygen. This occurs at PS II ( photosystem II), which is a structure present in the thylakoid membrane of chloroplast. The electrons released then participate in the electron transport chain.

Molecular oxygen is released in the atmosphere.

Why are the core and mantle still so hot?Which layers of the earth are solid vs. liquid and why?

Answers

The mantle and core of the earth are still hot because of the pressure of the overlying earth layers. The deeper the layer the hotter it is due to higher pressure, in lieu of the fact that temperature and directly proportional. In addition, some of the heat from the time the earth was formed is still trapped inside the earth and nuclear decay of radioactive elements in the regions ensure the earth does not cool.



The mantle and outer core of the earth are liquid while the inner core is solid. The former  layers are liquid because the temperatures in these regions have surpassed the melting point of the elements that make up the layers. However, the inner core remains solid due to the enormous pressure in the region. The pressure is so high it prevents the element in the region from melting.  


Why do water droplets form on the outside of a glass of ice water??

Answers

It is because of condensation. When warm air hits the cold surface, it condenses, leaving droplets of water outside the glass.

Another way of putting it is, when water vapor in the air comes in contact with cold, like ice water, the molecules slow down and get closer together, causing the gaseous water vapor to turn back into liquid water droplets, which is condensation.

Final answer:

Condensation causes water droplets to form on the outside of a glass of ice water. This happens when warm, moist air comes into contact with the cold glass, cooling the air and reducing its ability to hold water vapor. Consequently, water vapor condenses to form water droplets on the glass's surface.

Explanation:

Water droplets form on the outside of a glass of ice water due to a process called condensation. This process occurs when the warm, moist air outside comes in contact with the cold glass pane, causing the air to cool and its capacity to hold water vapor decreases. As a result, water vapor condenses to form liquid water, or droplets, on the exterior of the glass.

The fact that warm, moist air carries more water vapor than cold air is a fundamental principle of physics. It's also important to note that the actual amount of water vapor in the air does not change, only its relative capacity to hold water vapor, due to temperature changes.

A. prophase I of meiosis
B. anaphase of mitosis
C. telophase of mitosis
D. telophase II of meiosis

Answers

It would be Anaphase of mitosis since its the separation between the two chromosomes while the two chromatids on each side move to opposite directions. -maclittleseed

The drug colchicine inhibits the formation of spindle fibers during mitosis. If you treat dividing plant cells with colchicine, what would you expect the result to be? AThe chromosomes are halved during cell division and the result is a cell that has half the number of chromosomes than it would normally have.
B. The chromosomes do not pull apart in an orderly fashion during cell division and the result is two cells with unequal numbers of chromosomes.
C. The chromosomes are separated during prophase and each of the four daughter cells receives a haploid number of chromosomes.
D. The chromosomes do not pull apart during cell division and the result is a cell that has double the number of chromosomes than it would normally have.

Answers

The correct answer is: D. The chromosomes do not pull apart during cell division and the result is a cell that has double the number of chromosomes than it would normally have.

Colchicine is alkaloid produced by many plants and it is mitotic inhibitor. Colchicine inhibits the micro tubules to assemble to form spindle fibers, so consequently, chromosome segregation and the cell division are arrested at metaphase.


Option D) is correct. 'The chromosomes do not pull apart during cell division and the result is a cell that has double the number of chromosomes than it would normally have. '

Researchers and breeders utilize colchicine-induced polyploidy to create new plant varieties with improved characteristics, demonstrating its role in agricultural and biological research.

Colchicine functions as a disruptor of mitosis by inhibiting the formation of spindle fibers, which are essential for chromosome segregation.In the absence of functional spindle fibers, chromosomes fail to separate during cell division.This leads to a condition known as polyploidy, where a cell can end up with double the normal number of chromosomes. Thus, option D) is correct.

In plant cells, treatment with colchicine results in cells with multiple sets of chromosomes, which can have practical applications in plant breeding and genetic research.

Polyploidy induced by colchicine can produce plants with desirable traits such as larger flowers or fruits, increased vigor, or enhanced resistance to diseases.

Scientists often use bacteria to produce recombinant DNA, which in turn is used to create multiple copies of genes or express proteins. When introducing a foreign DNA into bacteria, the DNA fragment is first inserted into a plasmid. A plasmid is a small circular DNA molecule that can replicate independently of the bacterial chromosomal DNA. These plasmids are also known as vectors as they can carry foreign DNA from one organism to another, and, thus, used as a vehicle for gene cloning. Once inserted, the foreign DNA is replicated along with the rest of the bacterial DNA through the division of the bacterial cells.

Answering the student's question, the small circular piece of bacterial DNA, separate from the main chromosome, into which a foreign gene is inserted is called a plasmid. Therefore, the correct option is B. Plasmid.

Answers

Question: What are linked genes?

Answer: genes on the same chromosome that are inherited together

Explanation: this is because these genes are not inherited by themselves

question answered by

(jacmorris04)

Final answer:

Linked genes are genes on the same chromosome that are inherited together during cell division because they are located closely together. These genes often lead to unique patterns of inheritance.

Explanation:

Linked genes are genes that are located on the same chromosome and thus are likely to be inherited together during the cell division process. This is because they are situated so close to one another on the same chromosome that they do not separate independently, a key tenet of Mendelian genetics. Because of this, linked genes often show genetic traits or phenotypes that violate the principle of independent assortment, leading to unique patterns of inheritance.

For example, in fruit flies, the gene for eye color and the gene for wing size are linked genes. This means that if a parent has red eyes and large wings, their offspring are much more likely to also have red eyes and large wings because these traits are often inherited together due to the close proximity of their respective genes on the chromosome.

What is CODIS? How does it work?

Answers

The Combined DNA Index System (CODIS) is the United States national DNA database created and maintained by the Federal Bureau of Investigation. CODIS consists of three levels of information; Local DNA Index Systems (LDIS) where DNA profiles originate, State DNA Index Systems (SDIS) which allows for laboratories within states to share information, and the National DNA Index System (NDIS) which allows states to compare DNA information with one another.

Answer:

CODIS stands for Combined DNA Index Systems and is a computer program that stores the DNA Fingerprint of convicted criminals and missing persons. This program is very useful in forensic science.

Explanation:

CODIS is a computer program maintained by the FBI, which operates databases across the country. These databases contain more than five million profiles. CODIS covers several different indices.

CODIS uses algorithms to compare 13 different locations in STRs, plus one that determines the gender of the person in question. The system has rules and safeguards to protect the privacy of people in the database. Algorithms that point to positive results - which must be confirmed by an analyst - can provide clues to the police or even identify a possible criminal. The downside of using CODIS is that it only covers the profiles it includes - and there are over a million profiles waiting to be included in the system.

All living things use nitrogen to

Answers

Final answer:

All living things use nitrogen to create amino acids, proteins, and nucleic acids. Nitrogen in the atmosphere is unusable for most organisms until it is fixed by certain microorganisms into compounds like nitrates or ammonia. Plants absorb these compounds and are then consumed by animals, passing the nitrogen through the food chain.

Explanation:

All living things use nitrogen to synthesize important biological molecules necessary for life. Nitrogen is critical for the production of amino acids, which are the building blocks of proteins, as well as nucleic acids such as DNA and RNA. While the atmosphere is approximately 79% molecular nitrogen (N2), this form of nitrogen is largely inaccessible to most organisms because they are unable to break the strong triple bond that N2 molecules possess.

Therefore, the nitrogen must be 'fixed' into a more usable form, such as nitrates or ammonia. This nitrogen fixation is performed by certain microorganisms, including those in the species Rhizobium, which are found in root nodules of legumes, and cyanobacteria present in soil and water environments. Once nitrogen is fixed, plants can absorb it and incorporate it into organic compounds. Herbivores and carnivores then obtain their necessary nitrogen by consuming plant material or other animals.

what type of molecule is hemoglobin

Answers

Hemoglobin consists of protein subunits (the "globin" molecules), and these proteins, in turn, are folded chains of a large number of different amino acids called polypeptides. The amino acid sequence of any polypeptide created by a cell is in turn determined by the stretches of DNA called genes.

Final answer:

Hemoglobin is a protein molecule with a heme group that contains iron, essential for oxygen transportation in the blood.

Explanation:

Hemoglobin is a complex protein molecule found in red blood cells, which is crucial for transporting oxygen throughout the body. It consists of four subunits, each made up of a polypeptide chain called globin and a heme group. The heme group contains an iron ion (Fe²⁺) that can bind to oxygen molecules. When all four iron ions in a hemoglobin molecule are bound to oxygen, the blood appears bright red, indicative of oxygenated arterial blood. Hemoglobin's ability to carry oxygen is due to its iron centers, which can only transport oxygen when in their reduced Fe²⁺ state, as oxidation to Fe³⁺ prevents the binding of oxygen.
