Write the role of following digestive glands in brief ---- 1) Liver 2) Pancreas |
|
Answer» An alimentary canal and digestive glands are parts of HUMAN digestive system. The various parts of the alimentary canal includes mouth, teeth, esophagus, pharynx, stomach, small intestine (duodenum, JEJUNUM and ileum), large intestine, anus. Digestive glands includes salivary glands, PANCREAS, liver, gastric glands and intestinal glands. Out of these, salivary glands, pancreas and liver are major glands. The main function of salivary gland is to produce saliva which aids in digestion. Hepatic cells of liver secrete BILE that pass into the gallbladder through the hepatic ducts. The hepatic duct from the liver and cystic duct from the gallbladder forms the common bile duct. Pancreas secretes the digestive enzymes into the small intestine in the form of pancreatic juice. |

Describemegasporogenesis. with diagram |
|
Answer» tion:Megasporogenesis refers to the DEVELOPMENT of megaspores from the megasporocyte, the cell that undergoes meiosis. Meiosis of the megasporocyte nucleus results in the formation of four HAPLOID megaspore nuclei. In most taxa, meiosis is followed by cytokinesis, resulting in four megaspore cells. This pattern is termed monosporic megasporogene - sis; because of the four megaspores PRODUCED, only one of them contributes to the FEMALE GAMETOPHYTE . In some angiosperm taxa, however, cytokinesis occurs after the first meiotic division, but not the second, resulting in two cells, each of which contain two haploid nuclei. This developmental pattern is termed bisporic megasporogenesis because one of the binucleate cells, containing two megaspore nuclei, contributes to the female gametophyte . Finally, in other taxa cytokinesis does not occur at all after meiosis, resulting in a single cell with four haploid nuclei. Because all four haploid megaspore nuclei contribute to the female gametophyte, this pattern is termed tetrasporic megasporogenesis for diagram u can look into ncert |

WHAT IS SPACED PRACTICE? and how can we UNDERSTAND THE SPACED PRACTICE METHOD ? |
| Answer» SPACED practice is a study technique where students review material over a long period of time. This gives their minds time to form connections between the IDEAS and concepts so knowledge can be built upon and easily RECALLED later.Explanation:Before you understand how the spacing study method works, there’s another important part of the equation: the forgetting curve. The forgetting curve is how much knowledge is lost over time when our brains don’t put in any effort to remember it. Just learning something once isn’t enough. Your child NEEDS to revisit that material and review it over time in order for it to really stick. Unless your child works to review the material he or she has learned, most of that material will be forgotten in a matter of DAYS or weeks. This is where spaced practice comes in. | |
