In EARTHWORM carbon dioxide and NITROGENOUS WASTES are the main waste materials. The carbon dioxide is excreted out from the BODY through its moist skin by the process of diffusion. The nitrogenous wastes are excreted out of the body by special excretory organs called nephridia (singular nephridium).

(i) These UMBRELLA - like organisms are called gilled mushrooms which are edible spore-producing fruiting bodies. These organisms are fungi and they GROW on decaying ORGANIC matter
(ii) No , all species of mushrooms are not edible as some as some of these species are HIGHLY poisonous. Agaricus compestris is a common edible mushroom
(iii) Mushroom are rich in minerals, VITAMINS, etc.

The Golgi apparatus, also known as the Golgi COMPLEX, Golgi BODY, or simply the Golgi, is an organelle found in most eukaryotic cells. Part of the endomembrane system in the cytoplasm, it packages proteins into membrane-bound VESICLES inside the cell before the vesicles are sent to their DESTINATION

Dehydration is simply the removal of water from aqueous-fixed tissue. Since most fixatives are aqueous, this step is NECESSARY to prepare the tissue for embedding in non-aqueous media like paraffin. Alcohols are most commonly used in the laboratory for tissue dehydration, since they are miscible with aqueous fixatives like 10% formalin. In this step, the alcohol penetrates tissue quickly and the water is replaced with alcohol. Since alcohols act rapidly and may shrink and HARDEN tissue too much, care must be taken when CALCULATING the amount of time needed in the dehydration step. This step is performed at room temperature. Ethyl alcohol and isopropyl alcohol are used most often, with METHANOL and butanol being used to some DEGREE in special techniques. Since most alcohols (with the exception of isopropyl alcohol) and paraffin are NOT miscible, another step, known as clearing, is introduced.Explanation:Dehydration of tissues is the important process because of the paraffin, in which the tissues are embedded, is not miscible with water and does not penetrate the tissue effectively. Hence water in the tissue should be removed before embedding; this process is called as dehydration. Tissues are generally soft after fixation and thus for satisfactory staining and the right degree of hardening, the tissue is treated with the dehydrating agent.THE IDEAL TECHNIQUE OF DEHYDRATIONWater is extracted from the tissues by passing them through the graded alcohol as 70%, 80%, 90% and then Absolute alcohol. This technique prevents the mechanical damage to delicate intracellular structures, which may occur due to the rapid passage of water from the cells to the dehydrating medium.

Moreover, it also makes you a man of habit. This creates a very good IMPRESSION in front of others. Punctuality is an etiquette which encourages us to complete our work in a timely fashion. It also makes us realize the importance of time. A person who is punctual will ALWAYS know how to respect their time and others as well.Importance of PunctualityPunctuality is of great importance, it is truly underestimated and must be given UTMOST importance. When a person becomes punctual, everything else falls into place. You get discipline in life and also earn the respect of the others.Subsequently, a punctual person works on time without any hindrance. The people who are employed in armies and navies are given rigorous training to become disciplined and punctual. They pay no heed to any circumstances be it RAIN or thunder, they care about their punctuality.Furthermore, punctuality pushes the person to achieve success at faster rates than others. We must develop this quality in children from an early age which will MAKE it easy for everyone to lead a better life. When a person is punctual, they get utmost respect and admiration by society and reach greater heights than an unpunctual person.

PlantaeThese are Eukaryotic, MULTICELLULAR organisms with a cell wall that is made up of cellulose. They are autotrophs and synthesize their own FOOD through the process of photosynthesis. This kingdom includes all PLANTS.

orm PHOTOSYNTHESIS, plants need three things: CARBON DIOXIDE, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny HOLES in a plant's LEAVES, flowers, branches, stems, and roots. Plants also require water to make their food.

Budding is also known on a multicellular level; an animal example is the hydra, which reproduces by budding. The buds GROW into fully MATURED individuals which EVENTUALLY break away from the parent organism. Internal budding is a process of asexual reproduction, favoured by parasites such as TOXOPLASMA gondii...hσpє ít hєlps uh..

tion:hlo mate here's your answer Why do we call our heart myogenic?AnswerVerified90K+ ViewsHint: Some special types of muscle cells are present in the heart that are capable of generating regular impulses without any activation from the outside of the heart.Complete answer:In the heart, entire pumping (of blood) activity is done by the contraction of muscles. Thesecontractions in the human heart are activated by a specialized altered muscle of the heart known as the sinoatrial node (SA node) which is positioned in the right atrium. The SA node has the inherent capability to generate a wave of contraction and also controls the heartbeat. This is the REASON it is termed as the pacemaker of the heart. As the heartbeat is TRIGGERED by the sinoatrial node, and the impulse of contraction originates in the heart, the human heart is thus known as myogenic.In humans, the Heart is situated inside the thoracic cavity and is protected by the chest bone. The human heart consists of FOUR chambers namely left and right atrium and also left and right ventricle. In the heart oxygenated blood flows from Lungs to the left atrium and from there it flows into the left ventricle. From the left ventricle, oxygenated blood is pumped into the various parts of the body. The deoxygenated blood from the whole body is collected into the right atrium, from where it flows into the right ventricle and finally pumps towards the lungs for oxygenation.As the heartbeat is triggered by the sinoatrial node, and the impulse of contraction originates in the heart, the human heart is thus known as myogenic.i hope its help you MARK as brainlist ok

tion:The Harappan civilization is known as the earliest civilization of south-Asia subcontinent. It flourished during third second millennium B.C. It covers an appreciably larger area than the early dynastic Egypt or Sumer. Like other ci vilization Harappan civilization seems to have grown out of the skillful exploitation of the rivers valley resources in the north -western region of the Indo-Pakistan subcontinent. The Harappan sites provided evidences of systemic town planning, fortificati ons, elaborate drainage system, granaries etc. which throw light on the surplus economy, standardization of brick size, weight and measures, geometric instruments, linear scales and plumb-bobs. The Harappans were the first who gave the IDEA of the welfare of workers for the first time by establishing separate workers. Which now has become a necessity in welfare state. A unique type of hydraulic architecture is another legacy of the Harappan civilization. The Harappan people constructed their houses on immense platforms of mud or mud bricks. The Harappan cities were equipped with numerous wells, bathrooms and an intricate system of drains. The elites who lived in different parts of the cities did not constructed elaborate centralized places or temples as was common in Mesopotamia and Egypt, but they maintained well planned cities with massive walls and gateways to protect the citizens and to control trade. The evidence found during 185 excavations revealed that the Harappan civilization EVOLVED from local culture that had its roots, extending back thousands of years to the earliest fa rming and pastoral communities. Harappan civilization was spread over vast area. Its SETTLEMENT RUNS broadly from Sutkagendor in Makran (Pakistan) in the west to Hulas in District Saha ranpur U.P. (India) and Rehman Dheri (North Pakistant) in the north, Diamabad in Maharashtra (India) in the south and covers about 2,17,557 SQ. km. Kenoyer estimated it about 6,80,000 sq. km. The earliest civilization of south-Asia is known as Indus Valley Civilization because a large number of sites were discovered in the Indus valley. The term Indus civilization was given by Sir John Marshall in 1926. The south Asian archaeologist S.P. Gupta called it Indus Saraswati or Saraswati (Hakra) civilization. He discovered a large number of Harappan sites in the Saraswati (Hakra) and its tributaries region.
