  • Phylum Mollusca is the second largest animal phylum.
  • They are bilaterally symmetrical, triploblastic and coelomate animal.
  • Body is covered by a calcareous shell and is unsegmented with a distinct head, muscular foot and visceral hump.
  • A soft and spongy layer of skin forms a mantle over the visceral hump, the space between the hump and the mantle is called the mantle cavity in which feather like gills are present.
  • The anterior head region has sensory tentacles and the mouth contains a file-like rasping organ for feeding, called
  • They are usually dioecious and oviparous with indirect development.

Examples- Pila (Apple snail), Pinctada (Pearl oyster).

Non-chordates are animals without a notochord – the rod-like elastic structure that supports the body. This phylum consists of a small group of worm-like, marine species with an organ-system level of organization.

NON-CHORDATES

(i)Notochord is absent

(ii)Gill slits are absent

(iii)Exo skelton are present

(iv)Haemoglobin when present is in the blood plasma

(v)Example- Platyhelminthes, Nematodes, Molluscs

Multiple fission

1. Forms two daughter individuals

1. Forms many daughter individuals

2. Divides only once

2. Divides repeatedly

3. No residue is left

3. Residue is left

4. Takes place in favourable conditions

4. Takes place in favourable as well as unfavourable conditions

5. Immortality is present

5. Immortality is absent

Example: Amoeba reproduces by binary fission

Mahatma Gandhi believed in the ideology of Swedeshi ie, to use everything that is made in India. During the colonial period, the British had discouraged the Indian textile industries and promoted the British made goods especially the textiles. This lead to the closure of several Indian hand loom industries and many weavers were hit hard. Gandhi and other leaders in order to promote swedeshi goods encouraged the people to spin yarn and weave Khadi. This hit the British textile industries hard and provided work to many Indian artisans and weavers.

Let the no at tenths place= x And the no at ones place=y :. the no will be (10x+y) A/Q 7(10x+y)=4(10y+x) 70x+7y=40y+4x 66x=33y x=y/2 Given the difference between them is 3. Since x is less then y-x=3 Put the value of x y-y/2=3 y=6 : . x=3 Hence, the original no is 36 and the reverse no is 63.

I am asking dynamo rule... Not dynamo

Yogita Ingle 5 years, 3 months ago

Dynamo is an electric generator. It produces direct current by converting mechanical energy into electricl energy . It consists of a strong electromagnet between the poles of which is rotated an armature , consisting of a number of coils suitably wound. It is based on the principle of electromagnetic induction.

Vishal Upadhyay 5 years, 3 months ago

Generators that produces direct current with the use of a commutator are called Dynamos.

Ethanol is liquid at room temperature with pleasant odour while ethanoic acid has vinegar like smell. The melting point of ethanoic acid is 17℃. Ethanol does not react with sodium bicarbonate but ethanoic reacts with sodium bicarbonate releasing CO2 gas. Ethanol does not change the color of blue litmus paper while ethanoic acid change the color of blue litmus to red.

The major limitations of Newlands' law of octaves are- It was applicable to only lighter elements having atomic masses upto 40u, i.e., upto calcium. After calcium, the first and the eighth element did not have similar properties. Those elements that were discovered after Newland's octaves did not follow the law of octaves.  Some similar elements have been separated from one another while some dissimilar elements have been placed in the same column. That my answer?✌

In biology, regeneration is the process of renewal, restoration, and tissue growth that makes genomes, cells, organisms, and ecosystems resilient to natural fluctuations or events that cause disturbance or damage.[1] Every species is capable of regeneration, from bacteria to humans.[2][3] Regeneration can either be complete[4] where the new tissue is the same as the lost tissue,[4] or incomplete[5] where after the necrotic tissue comes fibrosis.[5] At its most elementary level, regeneration is mediated by the molecular processes of gene regulation and involves the cellular processes of cell proliferation, morphogenesis and cell differentiation.[6][7] Regeneration in biology, however, mainly refers to the morphogenic processes that characterize the phenotypic plasticity of traits allowing multi-cellular organisms to repair and maintain the integrity of their physiological and morphological states. Above the genetic level, regeneration is fundamentally regulated by asexual cellular processes.[8] Regeneration is different from reproduction. For example, hydra perform regeneration but reproduce by the method of budding. The hydra and the planarian flatworm have long served as model organisms for their highly adaptive regenerative capabilities.[9] Once wounded, their cells become activated and restore the organs back to their pre-existing state.[10] The Caudata ("urodeles"; salamanders and newts), an order of tailed amphibians, is possibly the most adept vertebrate group at regeneration, given their capability of regenerating limbs, tails, jaws, eyes and a variety of internal structures.[2] The regeneration of organs is a common and widespread adaptive capability among metazoan creatures.[9] In a related context, some animals are able to reproduce asexually through fragmentation, budding, or fission.[8] A planarian parent, for example, will constrict, split in the middle, and each half generates a new end to form two clones of the original.[11] Echinoderms (such as the sea star), crayfish, many reptiles, and amphibians exhibit remarkable examples of tissue regeneration. The case of autotomy, for example, serves as a defensive function as the animal detaches a limb or tail to avoid capture. After the limb or tail has been autotomized, cells move into action and the tissues will regenerate.[12][13][14] In some cases a shed limb can itself regenerate a new individual.[15] Limited regeneration of limbs occurs in most fishes and salamanders, and tail regeneration takes place in larval frogs and toads (but not adults). The whole limb of a salamander or a triton will grow again and again after amputation. In reptiles, chelonians, crocodilians and snakes are unable to regenerate lost parts, but many (not all) kinds of lizards, geckos and iguanas possess regeneration capacity in a high degree. Usually, it involves dropping a section of their tail and regenerating it as part of a defense mechanism. While escaping a predator, if the predator catches the tail, it will disconnect

Sania Maria Biju 5 years, 3 months ago

REGENERATION : When the simple animals like Hydra ,Planaria develop a new individual from their broken older part it is as regeneration. It is carried out by specialised cells which divide and differentiate to form the complete individual. These cells multiply and from this mass of cells other parts are generated. Regeneration follows an organised sequence referred to as DEVELOPMENT.

Following are the various advantages of tissue culture technique:

  1. The plantlets are obtained in a very short time with a small amount of plant tissue.

  2. The new plants produced are disease-free.

  3. The plants can be grown throughout the year, irrespective of the season.

  4. A large space is not required to grow plants by tissue culture technique.

  5. The production of new varieties in the market place speeds up.

  6. This technique is being used for the production of ornamental plants such as dahlia, chrysanthemum, orchids, etc.

Variation is the change in characters or traits of an individual which has not existed in their parents.
Variations can be of many types. If mutation occurs, there is a sudden change in the number or structure of genes or chromosomes. This change lasts generation after generation. For example, in the atomic bombing of Hiroshima and Nagasaki in 1945, the structure of genes of people changed. This is lasting till now. Moreover in disasters like Radioactive leakage, mutations can occur.
Variations lead to Evolution. This fact has lead to development of humans from ape.

Variation, in biology, any difference between cells, individual organisms, or groups of organisms of any species caused either by genetic differences (genotypic variation) or by the effect of environmental factors on the expression of the genetic potentials (phenotypic variation).... hope it would be helpful✌
