What pigment in plant cells makes photosynthesis possible?.

To find the number, we can set up the equation:

43 x 3 + 28 = 137

Therefore, the number is 137.

Another division problem with a quotient of 3 and a remainder of 28 could be:

85 ÷ 19 = 3 remainder 28

The most numerous EEC in the GI tract, enterochromaffin (EC) cells are extensively dispersed and can be found in the colon, rectum, appendix, duodenum, jejunum, and gastric antrum.

The gastric glands include enteroendocrine cells, particularly at the base of the glands. The post-ganglionic fibres of the vagus nerve have the ability to release gastrin-releasing peptide under parasympathetic stimulation to induce secretion, which is how the G cells secrete gastrin.

Specialized cells called enteroendocrine cells can be found in the pancreas, stomach, and gastrointestinal system. They respond to a variety of events by producing and releasing hormones.

7.3 kcal/mol of energy  is released when the outermost phosphate bond of ATP is hydrolyzed under standard conditions.

When outermost high energy phosphate bond is hydrolyzed, breaking the the phosphate bond on the end. ATP turns into adenine diphosphate plus an inorganic phosphate. Upon Hydrolysis one phosphate bond releases exactly 7.3 kJ of energy. The hydrolysis of Adenosine monophosphate releases 3.4 to 3.6 kJ of energy.

ATP hydrolysis is also termed as catabolic reaction by which chemical energy that has been stored in the high-energy phosphoanhydride bonds in adenosine triphosphate (ATP) is released after breaking out these bonds.

It is necessary to keep the solution faintly orange during bromination due to monitor the reaction and prevent overbromination.

Bromination is a chemical reaction in which an alkene is reacted with the bromine element. It is necessary to keep the solution faintly orange during bromination due to the following reasons:

1. To monitor the reaction: The reaction of bromine with the alkene should be stopped as soon as the first equivalent of bromine reacts with the double bond. Hence, it is essential to monitor the progress of the reaction by observing the color change. When bromine is added to the alkene solution, it forms a reddish-brown color. The reaction between the alkene and bromine occurs, and the reddish-brown color disappears.

So, if the reddish-brown color disappears, the reaction is complete. However, if the reddish-brown color remains, it means that the reaction is incomplete, and more bromine needs to be added to complete the reaction.

2. To prevent overbromination: The color change is due to the depletion of bromine. If excess bromine is added, it will lead to overbromination of the alkene. Overbromination leads to the formation of polybrominated products, which are not desired. Hence, the solution should be faintly orange to prevent overbromination.

The indispensable amino acid with the lowest recommended daily allowance is tryptophan. Tryptophan is an essential amino acid, meaning that it cannot be produced by the body and must be obtained through diet.

Tryptophan is a precursor to serotonin, a neurotransmitter that plays a role in regulating mood, appetite, sleep, and other physiological processes. Serotonin is often associated with feelings of well-being and happiness.Tryptophan can also be converted into niacin, a B-vitamin essential for energy production, DNA repair, and the functioning of the nervous and digestive systems.

The recommended daily allowance (RDA) for tryptophan is typically around 4 milligrams per kilogram of body weight. However, it is important to note that the specific RDA can vary depending on factors such as age, sex, and individual needs.

The first thing that happens in the human system is that the brain detects that the skin is too cold.

The brain senses the epidermis temperature and sends signals to the nervous system to direct the muscles to shaken and teeth to chatter. The muscles then warm the skin by shaking and chattering teeth. A reflex is a rapid, automatic response to a signal that does not involve conscious thought. The nervous system plays a crucial role in reflexes, as it receives the signals, processes the information, and sends a response to the appropriate muscles or organs. These reflexes are mediated by the spinal cord and do not involve the brain. The brain is the central organ of the nervous system in all vertebrates and most invertebrates. It is located in the head and is responsible for controlling and coordinating the body's functions and responses to the environment. It is the most complex organ in the body, and is composed of billions of nerve cells (neurons) and support cells (glia).

The pericarp, often known as the fruit cover, is made up of both full and unfinished layers. At maturity, the pericarp of all cereal grains is dry and primarily made up of empty cells. It supports and protects the developing endosperm and embryo throughout development. The inner epidermis is the pericarp's deepest layer.

The pericarp's layers each have a specific function in preserving and distributing the fruit's seeds. Some plants lack the fleshy mesocarp layer in their pericarp, including beans and sunflowers. Since they usually dry out and split open to release their seeds, these are regarded as dry fruit.

Fruit pericarp primarily aids in the protection and seed dissemination processes.

Seed Dispersal

The smell and variety of colors of the pericarp greatly aid in the dissemination of seeds. Fruits can be both dry and fleshy, and as a result, different seed dispersal media are used.

Protection of Seed

The periplasm, which is the innermost layer, is crucial for seed nourishment during developmental phases in addition to seed distribution. We are aware that an endocarp is situated closest to the seed and is attached to the ovary's placental layer by an umbilical structure (funiculus).

The statement "The THI-element is part of the operon that controls the synthesis of thymine in mRNA" is False.

Firstly, the THI-element is a regulatory region in bacterial genomes involved in the regulation of thiamine biosynthesis genes. The THI element, a highly conserved RNA secondary structure present in eubacteria and some archaea, has been identified as a potential regulator of thiamin metabolism. A search for THI elements and analysis of operon structures revealed a considerable number of newly identified thiamin-regulated genes, predominantly transporters, in various prokaryotes.

The action associated with the relaxation of a circular muscle is when the sphincter opening gets larger. The correct option is C.

Circular muscles, also known as sphincters, are found throughout the body and are responsible for controlling the opening and closing of various structures, such as blood vessels, digestive tract, and urinary system.

When a circular muscle relaxes, it allows for the widening or enlargement of the opening it surrounds.

For example, when the sphincter muscle in the digestive system relaxes, it opens up, allowing for the passage of food or waste material.

This relaxation and widening of the sphincter opening facilitate the movement of substances through the body. The correct option is C.

distance between the w and ct genes is 16-2 = 14 map units.

distance between the ct and t genes is 35-16 = 19 map units.

Coefficient of coincidence = the observed frequency of double recombinant/ expected frequency of double recombinant.

anticipated frequency of double recombinant =

Map distance between w and ct /100 * map distance between ct and t/100 = 14/100*19/100 = 0.0266

Translation in eukaryotes is more complex compared to bacteria because eukaryotic genes often contain introns that need to be removed by splicing before translation can occur. Eukaryotic mRNA also undergoes post-transcriptional modifications, such as capping and polyadenylation, which are important for translation initiation and stability. Eukaryotes have multiple subcellular compartments, which means that translated proteins may need to be targeted to specific locations within the cell.
