approximately what portion of the human genome is composed of repetitive, noncoding sequences?

Answers

Answer 1

Protein-coding genes only make up around 1% of DNA; the remaining 99% are non-coding.

Why does DNA behave as it does?

DNA contains the instructions necessary for a creature to develop, endure, and reproduce. In order to carry out these functions, proteins, which are the complex molecules that do the majority of the job in our bodies, must be made from DNA sequences that can be used as signals.

What is and where is DNA?

Deoxyribonucleic acid, also referred to as DNA, is a sophisticated molecule that houses all the data required for the growth and upkeep of an organism. A living thing's DNA is present in every cell. A multicellular creature's cells really carry almost all of the DNA needed for that organism.

a tumor that has advanced to regional structures is in which stage? 1. stage 1 2. stage 2 3. stage 3 4. stage 4

Answers

A tumor that has advanced to regional structures is in stage 4.

Stage 4 is the most advanced stage of a tumor. At this point, the tumor has spread to surrounding tissue and/or other organs, and is resistant to treatment. Symptoms of stage 4 cancer may include fatigue, pain, and difficulty breathing. Treatment options at this stage may include chemotherapy, radiation, surgery, or a combination of treatments. The goal of treatment is to improve patient quality of life and extend survival.

Tumor is an abnormal growth of cells, which can occur in any part of the body. It can be either benign (non-cancerous) or malignant (cancerous). Benign tumors are usually localized and do not spread to other parts of the body. Malignant tumors, on the other hand, can spread to other parts of the body and cause serious health problems. Treatment for tumors depends on the type and location. Treatment options include surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy and other treatments.

which mass extinction event occurred just before the rapid increase in speciation among mammalian species?

Answers

The Cretaceous-Paleogene mass extinction event, commonly referred to as the K-Pg extinction event, occurred just before the rapid increase in speciation among mammalian species.

The Cretaceous-Paleogene Mass Extinction Event and Its Impact on Mammalian Speciation

The Cretaceous-Paleogene (K-Pg) mass extinction event, which occurred 66 million years ago, was a global event that wiped out the majority of life on Earth. This event is most famously known for the extinction of the dinosaurs, but it also had major impacts on the evolutionary history of mammals.

Before the K-Pg extinction event, there were few mammalian species, but after the event there was a rapid increase in the number of mammalian species. This increase in speciation is thought to be due to the removal of the large dinosaurs, which opened up numerous niches for the smaller mammals to occupy. These new niches allowed for the evolution of new species and the increased diversity of mammals that we see today.

unlike signal transduction in many other sensory receptors, signal transduction in rods:_____.

Answers

Unlike signal transduction in many other sensory receptors, signal transduction in rods results in hyperpolarization of the sensory cell.

Sensory receptors can be found in specialized organs like the eyes, ears, nose, and mouth, as well as internal organs. Thus every receptor form expresses a distinguishable sensory modality that will eventually be combined into a single perceptual frame. This data is obtained through the transformation of energy into an electrical signal by specialized mechanisms. Potassium ions continue to leak out of the cell such as through potassium channels during hyperpolarization. Because potassium ions (positively charged ions) diffuse into the extracellular space, the membrane potential becomes more negative.

The procedure through which a physical or chemical signal is transferred through a cell as a sequence of molecular events, most frequently protein phosphorylation catalyzed by protein kinases, which results in a cellular response is known as signal transduction.

why is lingual lipase of minor importance when discussing nutrition and digestion in adults?

Answers

Lingual lipase is important for infant nutrition. Lingual lipase also reportedly contributes to the digestion of lipids in adults along with gastric lipase, especially in diseases with pancreatic insufficiency such as cystic fibrosis and alcoholic pancreatic insufficiency.

A convenient lipase assay that discriminates between pancreatic and lingual lipase activities was developed to describe some properties of the triglyceride-hydrolyzing activities of lingual lipase (from von Ebners glands) and pancreatic lipase. Secretion of lingual lipase is stimulated by feeding. Gastric contents collected postprandially from patients with cystic fibrosis (CF) contained lipase activity which is probably secreted from pharyngeal tissues. Also, duodenal contents from CF patients contained lipase activity with properties very close to those found in gastric contents from CF patients and controls. Apparently, the serous glands responsible for the secretion of lingual lipase is less affected than the exocrine pancrease in this disease. During fat balance experiments, CF patients utilized around 40% of the dietary lipids and more than 50% of milk lipids given as a test meal were hydrolyzed in the duodenum within 2 hr. In these patients with severe pancreatic insufficiency, we suggest that the lingual lipase is responsible for a considerable proportion of triglyceride hydrolysis. This hydrolysis starts in the stomach and continues in duodenum.

the thickening of the circular layer of the muscular externa at the location indicated by the arrows creates what?

Answers

The thickening of the circular layer of the muscular externa at the location indicated by the arrows creates pyloric sphincter.

The stomach has something called the pylorus, which connects the stomach to the duodenum. The duodenum is the first part of the small intestine. Together, the pylorus and duodenum play an important role in the movement of food through the digestive system.

The pyloric sphincter is a band of smooth muscle that controls the movement of partially digested food and juices from the pylorus to the duodenum.

What is its function?

The pyloric sphincter acts as a sort of gate between the stomach and small intestine. This allows the contents of the stomach to enter the small intestine. It also prevents partially digested food and digestive juices from re-entering the stomach. Helps mix with liquids. This mixture of food and digestive juices is called chyme.

The retina includes two kinds of photoreceptor cells: cones and rods. Cones are in charge of sharp color vision in daylight. In low light, the rods provide vision. The fovea is a comparatively tiny depression approximately 0.3 mm in diameter next to the center of the retina.

The retina of the human eye is an amazing illustration of photoreceptor protein. Many bacteria, including the extremophile bacterium Halohodospira halophila, comprise Photoactive Yellow Protein.

During deglutition, vocalization, and expiration, the lateral cricoarytenoid muscle enables inward rotation of the arytenoid on the cricoid cartilage, shutting the laryngeal airway.

This activity, which brings the arytenoids together, is enhanced by the interarytenoid muscle. When swallowing, voicing, or exhaling, the lateral cricoarytenoid muscle contracts, causing the arytenoid to rotate inward on the cricoid and closing the laryngeal airway.

Oligodendrocytes serve the same purpose in the cns that satellite cells do in the pns.T/F

Answers

The assertion is false. In the CNS, oligodendrocytes perform the same function as Schwann cells do in the PNS. The CNS's internal cavities are lined with ependymal cells. Neurons predominate over neuroglia in the brain.

In the peripheral nervous system (PNS), which is generated from the neural crest, Schwann cells are the oligodendrocyte counterpart. Oligodendrocytes and Schwann cells both play a key role in protecting and supporting axons.

The location is the main distinction. The peripheral nervous system is myelinated by Schwann cells, whereas the central nervous system is myelinated by oligodendrocytes. Additionally, oligodendrocytes have the ability to myelinate many axons, whereas Schwann cells can only do so for one axon per cell.

We can therefore conclude that the assertion is untrue. Similar to how satellite cells function in the PNS, oligodendrocytes have a function in the CNS. The interior cavities of the CNS are lined with ependymal cells. In the brain, neurons outnumber neuroglia in terms of density.
