Hence, it is called a\xa0blind sac.\xa0The main functions of the cecum are to absorb fluids and salts that remain after completion of intestinal digestion and absorption and to mix its contents with a lubricating substance, mucus. The internal wall of the cecum is composed of a thick mucous membrane, through which\xa0water\xa0and salts are absorbed. | |

What is reductive amination and transamination? |
| Answer» The key difference between reductive amination and transamination is that the reductive amination is the conversion of a carbonyl group into an amine group whereas the transamination is the transfer of an amine group from one molecule to another.Amination is the process that we can use to introduce an amine group to a molecule. The reductive amination and transamination are two forms of amination processes. Therefore, these processes also involve in the introduction of an amine group to a molecule, but in different pathways; reductive amination involves the conversion of an existing group into an amine group whereas transamination involves the transferring of an amine group. | |

These are commonly known as the waste disposal system of the cell which degrades and then removes all the wastes from the cell. | |

Where are the malleus attached at a opposite end |
| Answer» The\xa0malleus\xa0or hammer is a hammer-shaped small bone or ossicle of the middle ear which connects with the incus and is\xa0attached to\xa0the inner surface of the eardrum. The word is Latin for hammer or mallet. It transmits the sound vibrations from the eardrum to the incus. First, sound waves enter the external acoustic meatus, or ear canal, and vibrate the tympanic membrane that is located at the end of this canal. On the opposite side of the tympanic membrane, the medial side, the malleus is attached with its handle. This is where a series of movements of the auditory ossicles begins. | |

Where in a brain are the visual impulses analyse or recognized |
| Answer» Visual\xa0information from the retina is relayed through the lateral geniculate nucleus of the thalamus to the primary\xa0visual\xa0cortex — a thin sheet of tissue (less than one-tenth of an inch thick), a bit larger than a half-dollar, which is located in the occipital lobe in the back of the\xa0brain. The occipital lobe, known as the\xa0visual\xa0processing center, contains the\xa0visual\xa0cortex. Similar to the parietal lobe, the occipital lobe\xa0receives\xa0information from the retina and then uses past\xa0visual\xa0experiences to interpret and recognize the stimuli. | |

| Answer» Sensory\xa0neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism\'s environment into internal electrical impulses. For example, some\xa0sensory\xa0neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction.\xa0A sensory system is a part of the\xa0nervous system\xa0responsible for\xa0processing\xa0sensory information. A sensory system consists of sensory receptors, neural pathways, and parts of the brain involved in sensory perception. | |

What is pacemaker |
| Answer» Pace maker is a neuro muscular structure which produces and regulates cardiac impulses. Natural pacemaker is sino-atrial node (SA node).The SAN is a patch of cardiac musculature tissue present in the right upper corner of the right atrium. It has the ability to generate action potentials without any external stimuli, i.e., it is autoexcitable. The SAN can generate the maximum number of action potentials, i.e., 70-75 min–1, and is responsible for initiating and maintaining the rhythmic contractile activity of the heart. | |

In\xa0Closed Vascular Bundles, there is direct contact\xa0between\xa0phloem and xylem and Interfascicular cambium is absent.\xa0Open vascular bundles are\xa0the characteristic of dicotyledons (dicots). The cambium present between\xa0xylem\xa0and phloem is called FASCICULAR CAMBIUM. In\xa0closed vascular bundles, the cambium\xa0will\xa0be absent (fascicular cambium absent) and they\xa0do\xa0not show secondary growth (closed\xa0for secondary growth). | |

How does periderm formation take place in the dicot stem? |
| Answer» Periderm is composed of the phellogen, phellem, and phelloderm.During secondary growth, the outer epidermal layer and the cortical layer are broken because of the cambium. To replace them, the cells of the cortex turn meristematic, giving rise to cork cambium or phellogen. It is composed of thin-walled, narrow and rectangular cells.Phellogen cuts off cells on its either side. The cells cut off toward the outside give rise to the phellem or cork. The suberin deposits in its cell wall make it impervious to water. The inner cells give rise to the secondary cortex or phelloderm. The secondary cortex is parenchymatous. | |

Four similarity between blood and lymph.... |
| Answer» Blood is a red coloured liquid which circulates in our body. It is red because it contains a pigment called haemoglobin in its red cells.\xa0The main components of blood are:(i) Plasma: It carries all the dissolved substances such as proteins, digested food, common salt etc from one part to another part of the body.(ii) Red blood corpuscles (RBC): It carries oxygen from the lungs to all the cells of the body.(iii) White blood corpuscles (WBC): It fights infection and protects us from diseases.(iv) Platelets: It helps in the coagulation of blood in a cut or wound.Functions of blood:(i) It carries oxygen from the lungs to different parts of the body.(ii) It carries carbon dioxide from the body cells to the lungs for breathing out.(iii) It carries digested food from the small intestine to all the parts of the body.(iv) It carries waste product called urea from the liver to the kidneys for excretion in the form of urine.(v) It protects the body from diseases.Lymph is a light yellow liquid. It is a medium of circulation in human body which flows only in one direction - from body tissues to the heart. The functions of lymph are:(i) It takes part in the nutritive process of the body.(ii) It protects the body by killing the germs drained out of the body tissues with the help of lymphocytes contained in the lymph nodes, by making antibodies.(iii) It helps in removing the waste products like fragments of dead cells etc. | |

Reproduction system of cokroach |

Answer» Right..... hmm I know.. ? vhi toh yll inna dimag kismay hai Jo Sci, commerce nd arts subke question solve ker de including Junior class also. ? ? She use google ....and even she also reply maximum questions of 6th to 8th standard .....you can check.... by the way yogita ingle you answer every question whether the question is from science, commerce or arts.. Will you please tell us which stream you belongs to?? you type such a long answer yrr how??.. itna toh mai exam may V ni likhti. ? Itna bda answer type kiye ho Male Reproductive System: The male reproductive system of cockroach consists of a pair of testes. The testes lie on each lateral side in the 4th – 6th abdominal segments. A thin vas deferens arises from each testis. It opens into ejaculatory duct through seminal vesicle. The ejaculatory duct opens into male gonopore which is situated ventral to ****. A typical mushroom-shaped gland is present in the 6th-7th abdominal segments. It is an accessory reproductive gland. Male gonapophysis or phallomeres represent the external genitalia. These are made up of chitin. They are asymmetrical structures and surround the male gonopore. The sperms are stored in the seminal vesicles. The sperms are glued together in the form of bundles called spermatophores. Spermatophores are discharged during copulation.Female Reproductive System: The female reproductive system of cockroach consists of two large ovaries. The ovaries lie laterally in the 2nd – 6th abdominal segments. Each ovary is formed of a group of eight ovarian tubules or ovarioles. They contain a chain of developing ova. Oviducts from each ovary unite into a single median oviduct. This is also called ****** and it opens into the genital chamber. A pair of spermatheca is present in the 6th segment which opens into the genital chamber.Fertilization: Sperms are transferred through spermatophores. The fertilized eggs are encased in capsules; called ootheca. An ootheca is a dark reddish to blackish brown capsule. It is about 8 mm long. The oothecae are dropped or glued to a suitable surface; usually at a place with high relative humidity or near a food source. On an average, 9 – 10 ootehcae are produced by a female. Each ootheca contains 14 – 16 eggs. Development is indirect and is paurometabolous. Development through nymph stage is called paurometabolous. The nymph resembles the adults. The nymph grows by moulting about 13 times to reach the adult form. Wing pads are seen in the penultimate stage of development but wings are present only in adults. |
