How are viruses made??? |
|
Answer» Answer: HEY MATE ❤️❤️ Viruses are made by hijacking the host cell machinery. Viruses enter the cell by binding to RECEPTORS on the outside of the host cell. Once inside, the virus uncoats its genome and uses host cell machinery, such as RNA polymerase and ribosomes to read the INSTRUCTIONS and create more viruses. The viruses ASSEMBLE inside the host cell and either burst out, or bud out SLOWLY over time. Either way, the result is detrimental to the host cell whose RESOURCES are now diverted to making more viruses. HOPE HELPFUL FOR YOU ❤️❤️ |

What harmones are involved in the homeostasis of blood sugar |
|
Answer» Answer: HEY HERE IS YOUR ANSWER ❤️❤️ The two MAIN hormones involved in the homeostasis of glucose are insulin and glucagon. Insulin is the hormone of the well-fed state. When we eat a meal rich in carbohydrates the pancreas releases the hormone insulin. It travels through the blood and tells our cells to take up glucose from the blood, particularly cells in the LIVER and muscle. However, when we are in a "starved" state and blood glucose levels are low, the pancreas releases the hormone glucagon. Glucagon does the opposite of insulin and tells cells to break down glucose stores and release it into the blood. The pancreas regulates the BALANCE of glucose in this way to maintain homeostasis. HOPE HELPFUL FOR YOU ❤️❤️ |

Write a short note on double fertilization in angiosperms |
|
Answer» Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves the JOINING of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes (SPERM). It begins when a pollen grain ADHERES to the stigma of the carpel, the female reproductive structure of a FLOWER. The pollen grain then takes in moisture and begins to germinate, forming a pollen tube that extends down toward the ovary through the style. The tip of the pollen tube then enters the ovary and PENETRATES through the micropyle opening in the ovule. The pollen tube proceeds to release the two sperm in the megagametophyte. |

Write about digestive system in human bieng in short |
|
Answer» Chewing, in which food is mixed with saliva, begins the MECHANICAL process of digestion. This produces a bolus which can be swallowed down the esophagus to enter the stomach. Here it is mixed with gastric aciduntil it passes into the duodenum where it is mixed with a number of enzymes produced by the pancreas. Saliva ALSO contains a catalyticenzyme called amylase which starts to act on food in the mouth. Another digestive enzymecalled lingual lipase is secreted by some of the lingual papillae on the tongue and also from serous glands in the main salivary glands. Digestion is helped by the chewing of food carried out by the muscles of mastication, by the teeth, and also by the contractions of peristalsis, and segmentation.Gastric acid, and the production of mucus in the stomach, are essential for the continuation of digestion. Peristalsis is the rhythmic contraction of muscles that begins in the esophagus and continues along the wall of the stomach and the rest of the gastrointestinal tract. This initially results in the production of chymewhich when fully broken down in the small intestine is absorbed as chyle into the lymphatic system. Most of the digestion of food takes place in the small intestine. Water and some minerals are reabsorbed back into the blood in the colon of the LARGE intestine. The waste products of digestion (feces) are defecated from the anus via the RECTUM. |

|
Answer» Answer: ★Respiration is the process in which gas MAY be required or un-required is exchanged between organisms and their habitat. ★The act or process of breathing in which the inhaling of OXYGEN and the exhaling of carbon dioxide takes place. ★The process by which cells use oxygen to break down SUGAR and obtain energy is known as respiration. ★Breathing is the physical process where we inhale and exhale air in and out of your LUNGS. ➡There are 2 types of respiration : ★ Aerobic means respiration with air. This type of respiration needs oxygen. ★Anaerobic means without air respiration means without air. |
