Explanation:

Answer:A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. ... Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral.

Coastal oceans are commonly defined as the areas from the shoreline to the outer edge of the continental margin. They connect the continents to the open ocean and serve as a link for transporting organic and inorganic, natural and anthropogenic material from land to sea.

Coastal oceans in tropical areas have similar characteristics to their temperate counterparts. ... Coral reefs are biologically diverse and rich habitats that occur in relatively nutrient-poor environments along coastlines. Areas that have too many nutrients often harbor too much algal growth to sustain coral growth.,

Explanation:

Food and liquids are processed by the digestive system. After nutrients are absorbed during digestion, the excretory system removes solid waste products, or feces, through the rectum. The excretory system also works with the respiratory and circulatory systems and removes carbon dioxide (CO2) from the body.

Homeostasis, which refers to the body's capacity to maintain a steady internal environment despite changes in the external environment, is a state that is maintained by the respiratory, circulatory, lymphatic, excretory, and digestive systems working in concert. Although each of these systems has a unique job to do, they are all interrelated and dependent on one another to keep the body running smoothly.

The digestive system is in charge of converting food into nutrients that the body can absorb. It consists of the liver, pancreas, small and large intestines, stomach, mouth, oesophagus, and stomach. After then, the circulatory system delivers nutrients to the body's cells.

The kidneys, ureters, bladder, and urethra are part of it. The circulatory system and the excretory system collaborate closely to move waste materials to the kidneys for filtering and expulsion from the body.

The respiratory system is in charge of supplying the body with oxygen and expelling carbon dioxide. It consists of the lungs, trachea, bronchi, nose, and mouth. The respiratory system collaborates with the circulatory system to eliminate carbon dioxide and provide oxygen to the body's cells.

Nutrients, oxygen, and waste products are moved throughout the body through the circulatory system. It consists of the blood, blood vessels, and the heart. To provide nutrition and oxygen to the cells and eliminate waste, the circulatory system collaborates closely with the respiratory and digestive systems.

It is the job of the lymphatic system to remove extra fluid from bodily tissues and transport it back to the circulatory system. It consists of lymphatic organs like the spleen and thymus, lymph nodes, and lymphatic arteries. The lymphatic system contributes to immunological function and aids in the body's defence against illnesses and infections.

Overall, through controlling the body's internal environment, these systems cooperate to preserve homeostasis. For instance, the excretory system eliminates waste while the digestive system supplies nutrients for the body. These nutrients and waste materials are delivered to and removed from the body's cells via the circulatory system. The lymphatic system helps the body fight infections while the respiratory system supplies oxygen for cellular respiration.

Increase transcription of a gene - Activator

DNA binding protein - Ribosome

Block the promoter region of a gene - Repressor

Found associated with the gene encoding HCI production in a skin cell - mRNA

Found associated with the genes encoding hemoglobin in a red blood cell - mRNA

Explanation:

Hemoglobin is an iron containing compound present in red blood cells which carries oxygen in the body. mRNA molecule contains exon coding for two proteins. mRNA molecule becomes associated with four to six ribosomes.

The statements on the left are correctly matched with the choices given on the right are:

A gene is a basic unit of heredity and a sequence of nucleotides in DNA that encodes the synthesis of a gene product, either RNA or protein.

An activator is known to increase the transcription of a gene, while a repressor binds to the promoter region and inhibits the transcription process. The molecules of mRNA get associated with the gene HBA, HBB which encodes for hemoglobin in red blood cells. Ribosomes and polymerases are known for DNA binding protein.

Therefore, above are all the statements on the left that are correctly matched with the choices given on the right.

What is trophic level in ecosystem?

Trophic level is defined as the ranking of an organism in the food chain and which differ from a value of 1 for primary producers to 5 for marine  humans or mammals.

Racoon is mammal and omnivorous whereas the snake is carnivorous animal.  In a pond ecosystems, the biomass pyramid is inverted.

Answer:

Explanation:

Proteins, such as RNA (ribonucleic acid) polymerase, were loaded into lane 2. TFIIB and TFIID are two forms of TFII. These proteins attach to the fragment of DNA. Furthermore, these proteins shield DNA from the DNase enzyme, which may trigger DNA to split. As a result of the above findings, we may conclude that the inserting proteins(RNA polymerase, TFIID and TR 8 proteins) cover the area between 500 and 800 bp (base pair) in the DNase I footprinting experiment.

As a consequence, the length duration is 300bp since the promoter area is about 500-800bp and is not digested by DNase after incubation of inserting proteins.
