during the light reactions of photosynthesis protons are actively transported:
Answer:
During photosynthesis a proton gradient is maintained by the active pumping of protons across the thylakoid membrane into the lumen of the thylakoid. ... The light dependent reactions require photosynthetic pigments that are found embedded in the thylakoid membrane.
During photosynthesis a proton gradient is maintained by the active pumping of protons across the thylakoid membrane into the lumen of the thylakoid.
What is light reaction?The initial step of the photosynthesis process is called the light reaction, and it is at this stage that solar energy is turned into chemical energy in the form of ATP and NADPH. Both the protein complexes and the molecules of the pigment contribute to the synthesis of NADPH and ATP.
The thylakoid discs are the locations of the light response that takes place. There, oxygen (O2) is produced as a byproduct of the oxidation of water (H20). After being released from water, the electrons are then transferred to ATP and NADPH. Outside of the thylakoids is where the dark reaction takes place.

Earthquake and faults
Answer:
Hey mate.....
Explanation:
This is ur answer.....
Earthquakes occur on faults. A fault is a thin zone of crushed rock separating blocks of the earth's crust. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other. The fault surface can be vertical, horizontal, or at some angle to the surface of the earth.

B) latent
C) patent
D) plastic
Fingerprints in modern times are now used in detecting criminals from crime scenes. Fingerprints derived from these crime scenes can be obtained and visualized.
The type of fingerprint this is is a latent fingerprint.
Latent fingerprints can also be referred to as invisible type of fingerprints.To enable their use, they must be visualized through the use of various techniques which include dusting/iodine/super glue. Latent fingerprints are the most common type of fingerprints usually found at a crime scene. They are also much harder to detect and lift than any other type of fingerprints.Learn more about fingerprints: https://brainly.com/question/2114460
What is the difference between permanent gases and variable gases in the atmosphere?
Answer:
the difference is that permanent gases have larger residence times and Variable gases have shorter residence times
the difference between permanent gases and variable gases in the atmosphere is permanent gases are gases that have a very low dew point.
What are the characteristics of the atmosphere?The Earth's atmosphere is basically composed of a mixture of gases, being 78% Nitrogen, 21% Oxygen and 1% Argon. In addition, traces of carbon dioxide, water vapor and other gases are found, but in very small amounts.
In this way, permanent gases are gases that have a very low dew point.

Explanation:
what process can lead to an individual having too many or two few chromosomes?
The process which can lead to an individual having too many or two few
chromosome is as a result of mutation which occurs during meiosis.
Meiosis is the type of cell division which occurs in reproduction and the
production of sex cells such as sperm and egg. This process results in the
production of four unique daughter cells.
The homologous chromosomes not being properly distributed in the
process could lead to such types of error.

Regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.
Stem cells are specific cells capable of generating new specialized types of cells, thereby allowing the regeneration of damaged tissues.For example, hematopoietic stem cells can be used to generate new red blood cells whose function is to transport oxygen in the bloodstream.Regenerative cells can be used in tissue engineering in order to restore the function and structure of damaged organs.In conclusion, regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.

Publishing can play a major factor in how a scientist is regarded. This is because the number of publications scientists produce can affect who gets a raise, who gets hired, who gets fired, and who gets funding to do more experiments. Consequently, a phenomenon is known as “salami-slicing” has arisen in science. Instead of publishing a large comprehensive study containing all the results as one large paper, scientists often slice up the work into the smallest units possible and publish these as several separate papers—often in different journals.
Research the phenomenon of scientific salami slicing, and list at least two possible ethical problems that can arise from this practice.
Explain how this practice can affect the way that scientific information is disseminated to nonscientists.
Create a suggestion for a policy that scientists or science journals could follow that would reduce the amount of salami-slicing that occurs in research. Suggest any problems that the policy might cause.
Salami slicing is the procedure of dividing one single article research into several publications. It is an unethical practice because hampers the healthy competence between scientists for research (job) positions.
In the phenomenon referred to as 'salami slicing', a group of similar research articles published by the same research group are considered 'slices' of the same salami.
This practice can affect not only the work of scientists but also journalists who might report the same results once and again.
A possible solution for this problem is to create a Review Board consisting of experts capable of identifying salami slice articles and then punish the responsible parties.

Why can cells in the bone marrow produce both red and white cells
Answer:
1.Bone marrow produces red blood cells, platelets, and white blood cells. Lymphocytes are produced in the marrow, and play an important part in the body's immune system.
Explanation:
2.After entering the bloodstream, the hematopoietic stem cells travel to the bone marrow. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment.
3.Red blood cells are an important element of blood. Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which they carry to the lungs to be expelled. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts.
