Answer:

Protein synthesis occurs in the nucleus (transcription stage) and on the ribosome (translation stage)

Photosynthesis occurs in the chloroplast

Respiration in the mitochondria

Explanation:

The protein synthesis occurs in the ribosomes, the photosynthesis in the chloroplast, and the cellular respiration in the mitochondria of the cell.

The ribosomes play an important role in the cells. They translate the information present in the genetic code of the mRNA into a sequence of amino acids There are two types of ribosomes. These are the 70S and 80S types present in prokaryotic and eukaryotic cells respectively.

The mitochondria are known as the powerhouse of the cell and are responsible for producing all the cell’s ATP which is essential for the functioning of a cell.

The chloroplast is found in plant cells and in some prokaryotic algae as well. The main function of the chloroplast is to carry out the process of photosynthesis. This process is essential for the survival of not only plants but all the life forms that are dependent on them for energy in some or the other way.

Mesozoic Era

Explanation:

The "Mesozoic Era" is divided into three periods: Triassic, Jurassic and Cretaceous. During the last period (Cretaceous), which was considered the longest, the extinction of reptiles occurred and the new mammals appeared. This event was also known as the "Cretaceous-Paleogene Extinction Event." Around 3/4 of plants and animals died. Such event became significant boundary that laid between the Cenozoic Era and the Mesozoic Era. This made it significant in geologic history.

Alveolar Surface Tension is Reduced by Pulmonary Surfactant. A lipoprotein substance known as surfactant is secreted by type II alveolar cells.

While breathing in and out, oxygen and nutrients are exchanged between the blood and alveoli in the lungs. When oxygen is inhaled from the air, it gets to the body's tissues via the alveoli, blood, and structures inside the body.

An alveolus is made up of an extracellular matrix encircled by capillaries, a layer of simple columnar mucosa (very thin, flattened cells), and also an epithelial layer. The alveolar membrane, sometimes known as the oxygen diffuses, which permits the exchange of gases, includes the epithelial lining.

The phenotypic proportions which would be expected if the genes for red eyes and for white-banded wings were located on different chromosomes are:

(a)

The distance between the genes is four map units.

The rate of recombination between the genes for red eyes and those for white-banded wings is 4%.

(b)

The F1 heterozygote inherited a chromosome with alleles for red eyes and white-banded wings (re wb) from one parent and a chromosome with alleles for wild-type eyes and wild-type wings (re+ wb+) from the other parent. These are therefore the phenotypes of the nonrecombinant progeny, present in the highest numbers. The recombinants are the 19 with red eyes, wild-type wings and 16 with wild-type eyes, and white-banded wings.

A homozygous dominant genotype refers to an organism with two dominant alleles for a characteristic. This genotype is denoted by the letter BB using the example of eye colour. Heterozygous genotype refers to an organism with one dominant allele and one recessive allele.

Because purple is dominant to white in this case, all the progeny from this cross will be purple because they are all heterozygotes (Pp). Therefore, there is no chance that a child will have white blossoms. Purple flowers, 50% Pp (heterozygous), 25% PP (homozygous dominant), and 50% Pp make up the F2 generation (homozygous recessive, white flowers). The white trait returns in this way in the second generation. Purple to white is the phenotype, which is 3:1. Heterozygous refers to a plant with the genotype Pp (HET uhr OH ZIE guhs).

To reduce one molecule of O2 it takes 4 electrons.

Electron transfer is the last process of aerobic respiration that occurs in the inner membrane of mitochondria. In electron transport, the process of making ATP occurs which will later be used by cells to carry out activities in the body. The material for making ATP comes from NADH and FADH2 which are produced in glycolysis, oxidative decarboxylation, and the Krebs cycle. O2 acts as the final electron acceptor which will later form H2O which will be removed from the cell.

In electron transport, NADH and FADH are utilized in a series of oxidation-reduction reactions until finally used to reduce O2 to H2O. This redox reaction involving various protein complexes in the mitochondrial inner membrane is referred to as oxidative phosphorylation. The energy released in this redox process is converted into a high-energy molecule, namely ATP. To reduce one molecule of O2 it takes 4 electrons.

Fecal microbiota transplantation (FMT) is a procedure where healthy fecal matter is transferred from a donor into the gastrointestinal tract of a patient. It is used to treat various gastrointestinal conditions, including slow transit constipation (STC). STC is a condition where the movement of stool through the colon is slow and leads to infrequent or difficult bowel movements. Soluble dietary fiber is a type of fiber that dissolves in water and forms a gel-like substance in the digestive tract. It helps add bulk to the stool and promotes regular bowel movements. In the pilot study you mentioned, researchers investigated the effectiveness of combining FMT with soluble dietary fiber for the treatment of STC. The study aimed to evaluate whether this combination could improve symptoms and increase bowel movement frequency in STC patients. The exact details and results of the pilot study are not provided, as you only mentioned the study's title. However, it is likely that the researchers performed the study on a small group of STC patients and assessed the effects of FMT combined with soluble dietary fiber on their bowel movement patterns, symptom severity, and overall quality of life. To get more detailed information about the specific study, it would be helpful to refer to the original research article or consult with a medical professional who can provide a comprehensive analysis of the study's findings.

Fiber is a type of material in the form of component pieces that form a complete elongated network. The most common example of fiber is found in fabrics.

Quarterly​ time frame best describes when earthquakes occur.

An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.

Earthquakes are the result of sudden movement along faults within the Earth. The movement releases stored-up 'elastic strain' energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

Over 80 per cent of large earthquakes occur around the edges of the Pacific Ocean, an area known as the 'Ring of Fire'; this where the Pacific plate is being subducted beneath the surrounding plates.
