Explain the reactions from
Glycolysis, link reactions,
Krebs cycle to Electron
transport chain

Answers

Explanation:

Glycolysis is the stage where glucose is broken down into 2 pyruvates (3 carbon compounds). This occurs in the cytoplasm and produces 2 ATP molecules. The pyruvates enters the mitochondria and enters the link reactions where it combines with co enzyme A (CoA). Decarboxylation ( removal of CO2) and dehydrogenation (removal of H) occurs here. Since CO2 is removed from the pyruvate it means a carbon is removed. This produces a 2 carbon compounds called acetyl. The acetyl compound is what combines with the CoA to form a compound called acetylCoA. This compound then enters the Krebs cycle.

The CoA co enzyme leaves and the acetyl reacts with a four carbon compound called oxaloacetate. This then forms a 6 carbon compound compound called citrate. A series of dehydrogenation and decarboxylation reactions occur to convert the 6 carbon compound back to oxalaoactate( the 4 carbon sugar). An ATP molecule is formed during one spin of the Krebs cycle.

The electron transport chain is where the reduced NAD (formed from dehydrogenation in glycolyisis, the link reactions and Krebs cycle) and Reduced FAD ( formed from dehydrogenation in the krebs cycle). molecules pass along a series of electrom carriers where they release energy that will be used to make ATP. Oxygen is the last electron carriers

(b) The ash helps crops to grow bcuz it is rich in minerals, such as magnesium ions ,but it is deficient in nitrate ions.

Explain why nitrate ions and and magnesium ions are important for plants.

Answers

Answer:

B. The ash helps crops to grow because it is rich in minerals, such as magnesium ions, but it is deficient in nitrate ions.

Explanation:

After the forest is being burned, ash and carbon dioxide increase on the surface of the ground. It is good for the plant to grow because the plant uses carbon dioxide for photosynthesis, and its root absorbs energy from the ground where ash is very good for the plant to grow.

Discuss how destructive fishing practices damage coral reefs.

please explain. this is a written answer. only answer if you are 100%

Answers

Answer:

Apart from poisoning the fish, this toxic fishing activity kills animals that are essential to the aquatic environment, such as corals, and provide food and shelter for a number of marine species. One square meter of coral reef is lost with every fish captured using this method. Also, overfishing has the potential to deplete main reef habitats and damage coral habitat. In many places, rapid human population growth, increased demand, the use of more advanced fishery technology, and insufficient maintenance and regulation have resulted in the extinction of key coral species and habitat damage.

BTW, I used my own words

Answer:

When poisoning the fish other animals around in the aquatic envoiroment like for example corals, which porvide food and shelter for many species of underwater creatures. If this is not stopped coral reefs will become extint which is really bad not only for the species which feed and live there but also to the enviorment.

Answers

Answer:

Due to non-functioning of protein.

Explanation:

The cell division of cancer cells like these are misregulated because they can't be control by the proteins that is responsible for the control cell division. The cancer cells can multiply without any growth control factors, or growth-stimulating protein signals that control its growth. There are some proteins that is responsible for control of cell division but due to mutation that protein of substance stop working and the cancer cell grows uncontrollable.

Please summarize to answer, how do cells undergo differentiation to form the numerous types of cells in the body?
Cellular differentiation, or simply cell differentiation, is the process through which a cell undergoes changes in gene expression to become a more specific type of cell. The process of cell differentiation allows multi-cellular organisms to create uniquely functional cell trt42ypes and body plans. The process of cell differentiation is driven by genetics, and their interaction with the environment.
All organisms begin from a single cell. This single cell carries the DNA coding for all the proteins the adult organism will use. However, if this cell expressed all of these proteins at once it would not be functional. This cell must divide repeatedly, and the cells must begin the process of cell differentiation as they divide. The cell lines begin to emerge, and the cells get more and more specific. Eventually, an entire organism is formed with hundreds of different cell types from this process of cell differentiation.
The original mass of cells, which have not undergone differentiation, are known as stem cells. Unlike normal cell division, which creates two identical daughter cells, the division of stem cells is asymmetric cell division. In this case, one of the cells remains identical to the parent stem cell. In the other cell, chemical triggers activate the process of cell differentiation, and the cell will start to express the DNA of a specific cell type. Stem cells which can differentiate into entire organisms are known as embryonic stem cells and are said to be totipotent.
By contrast, the body also has many cells which are only pluripotent. These cells have already undergone some cell differentiation. These stem cells can only divide into a narrow range of cell types. Bone marrow, for instance, contains somatic stem cells which can only become red blood cells. These cells are necessary for the constant replenishment of blood cells, which are mostly inactive besides their oxygen-carrying ability.
Cell Differentiation Examples
In Animals
After the process of fertilization in animals, a single-celled organism called the zygote is formed. The zygote is totipotent, and will eventually become an entire organism. Even the largest animal on Earth, the blue whale, starts as a single cell. The complex tissues and organ systems, which are completely different in their form and function, all come from the zygote. The process of cell differentiation starts early within the organism. By the time the gastrula has formed, the cells have already started expressing various portions of the DNA.
These changes drive the first folding processes within the embryo. As the tissues continue to form, some cells begin releasing hormones, or chemical triggers which signal various cells to react. Hormone signals direct the expression of DNA in various body parts, which drives their cell differentiation further. In humans it only takes a little over a month for a rudimentary heart and circulatory system to form.
As the systems continue to form, many of the stem cells lose their totipotency, themselves undergoing cell differentiation. This allows for faster production of specialized cells, which the growing organism needs to sustain its growth and enter the world with success. Through cell differentiation, tissues as different as brain tissue and muscle are formed from the same single cell.

One of the pieces of evidence for evolution that Charles Darwin collected on his travels aboard the HMS Beagle was the observation of fossils of extinct animals and similar, but noticeably different species. Giant ground sloth fossils were very similar in shape to the bones of sloths that inhabited the regions of South America he was exploring. The main difference was the size, as the ground sloth fossils were significantly larger that the bones of the sloths he captured alive. What was a conclusion that Darwin was able to arrive to based on this piece of evidence

Answers

Answer: Darwin was able to arrive at a conclusion that there was no relationship between the fossils of the ground sloth and the bones of the captured sloths that currently reside in South America.

Explanation:

Evolution is defined as the sum total of adaptive changes that have taken place over a very long period of time. It leads to the development of new species from earlier ones. Evolution is an extremely slow process. It is difficult to obtain direct evidence of evolution in action. However, scientist such as Darwin, have gathered a great deal of indirect evidence that supports the theory of evolution. These evidence comes from many sources including:

--> fossils records

--> biochemical similarities

--> molecular records

--> Comparative anatomy and

--> embryology.

FOSSILS RECORDS shows the existence of species that are now in extinct which lived on Earth during different periods of the planet's history. They provide evidence that organisms from the past are not the same as those found today due to adaptive changes that has occurred over a long period of time on the organism in order to survive in its environment.

There was no relationship between the sloths because of the difference in BONE MASS.
