|
Answer» Answer: Define mycorrhiza. How it is beneficial for plants? Mycorrhiza is a symbiotic association between fungi and roots of higher plants. Benefits of mycorrhiza : The fungus DECOMPOSING the organic matter present in the vicinity of roots of higher plants provides nutrients to the root. Besides this, fungus also helps the roots in absorbing and retaininng the nutrients. Name two methods by which INSECTS can damage a crop? Generally insect pests attack the plants in three ways: (1) They cut the root, stem and leaf, (2) they suck the cell SAP from various parts of the plant and (3) they bore into stem and fruits Why leguminous plants are used in crop rotation? Leguminous crops are desired in crop rotation because these crops have the ability to fix atmospheric NITROGEN into the soil and hence can reduce the COST of nitrogenous fertilizer and is not harmful to the soil. |

Kartagener syndrome is a hereditary disease in which protein associated with the microtubules is lacking from cilia and flagella. How do you think Kartagener syndrome will affect a man’s ability to father a child? How might it effect his respiratory health? |
|
Answer» Answer: Primary ciliary dyskinesia is a disorder characterized by chronic respiratory tract infections, abnormally positioned internal organs, and the inability to have children (infertility). The signs and symptoms of this condition are CAUSED by abnormal cilia and flagella. Cilia are microscopic, finger-like projections that stick out from the surface of CELLS. They are found in the linings of the airway, the reproductive system, and other organs and tissues. Flagella are tail-like structures, similar to cilia, that propel sperm cells forward. In the respiratory tract, cilia move back and forth in a coordinated way to move mucus towards the throat. This movement of mucus helps to eliminate fluid, bacteria, and particles from the lungs. Most babies with primary ciliary dyskinesia experience breathing problems at birth, which suggests that cilia play an important role in clearing fetal fluid from the lungs. Beginning in early childhood, affected individuals develop frequent respiratory tract infections. Without properly functioning cilia in the airway, bacteria remain in the respiratory tract and cause infection. People with primary ciliary dyskinesia also have year-round nasal congestion and a chronic cough. Chronic respiratory tract infections can result in a condition called bronchiectasis, which damages the passages, called bronchi, leading from the windpipe to the lungs and can cause life-threatening breathing problems. Some individuals with primary ciliary dyskinesia have abnormally placed organs within their chest and abdomen. These abnormalities arise early in embryonic development when the differences between the left and right sides of the body are established. About 50 PERCENT of people with primary ciliary dyskinesia have a mirror-image reversal of their internal organs (situs inversus totalis). For example, in these individuals the heart is on the right side of the body instead of on the left. Situs inversus totalis does not cause any apparent health problems. When someone with primary ciliary dyskinesia has situs inversus totalis, they are often said to have Kartagener syndrome. Approximately 12 percent of people with primary ciliary dyskinesia have a condition known as heterotaxy syndrome or situs ambiguus, which is characterized by abnormalities of the heart, liver, intestines, or spleen. These organs MAY be structurally abnormal or improperly positioned. In addition, affected individuals may lack a spleen (asplenia) or have multiple spleens (polysplenia). Heterotaxy syndrome results from problems establishing the left and right sides of the body during embryonic development. The SEVERITY of heterotaxy varies widely among affected individuals. Primary ciliary dyskinesia can also lead to infertility. Vigorous movements of the flagella are necessary to propel the sperm cells forward to the female egg cell. Because their sperm do not move properly, males with primary ciliary dyskinesia are usually unable to father children. Infertility occurs in some affected females and is likely due to abnormal cilia in the fallopian tubes. Another feature of primary ciliary dyskinesia is recurrent ear infections (otitis media), especially in young children. Otitis media can lead to permanent hearing loss if untreated. The ear infections are likely related to abnormal cilia within the inner ear. Rarely, individuals with primary ciliary dyskinesia have an accumulation of fluid in the brain (hydrocephalus), likely due to abnormal cilia in the brain. |

Why is mitosis called equational division and meiosis called reductional division? |
|
Answer» Explanation: because in mitosis each daughter cell gets EQUAL SETS of chromosomes that the parent cell has so the number of chromosomes is equally divided and so it is called equational DIVISION while in meiosis, the daughter cell gets only half the sets of chromosomes that the parent cell has so the number of chromosomes is REDUCED hence it is called REDUCTIONAL division |

bird need to keep their body light to help inflying hence they show presence of some organs only on one side how their skeleton helps in reducing their weight |
Answer» Explanation:The bird skeleton is not heavy, it’s lightweight, and it has ENOUGH WITHSTANDING power and stress handling power. The KIND of bone arrangement and hallow BONES makes the skeleton lighter to fly and allows the more oxygen to absorb from the surrounding ATMOSPHERE for a more energetic and smooth flow. The other important factor is an eye, the eye makes them be in balance in the atmosphere, it can focus on all 360 degrees for any hindrance. Hence it flies safely. |
