What do U meanExplanation:

tion:Tissue culture, a METHOD of biological RESEARCH in which fragments of tissue from an ANIMAL or plant are TRANSFERRED to an artificial environment in which they can continue to survive and FUNCTION. The cultured tissue may consist of a single cell, a population of cells, or a whole or part of an organ

tion:Division of labour is ADAPTATION of different PARTS of an ORGANISM to carry out different functions. Hence, there are several kinds of TISSUES, each with specific properties to carry out specific function in the body.

The plant having GENOTYPE AABBCC is heterozygous for only one character B. Number of gametes = , where N is the heterozygosity. Since n = 1 so 2 gametes will be FORMED. Those are ABC and AbC. So the two types of gametes will be ABC and AbC.

1)A chromosome is a string of DNA wrapped around associated proteins that give the connected nucleic acid bases a structure. During INTERPHASE of the cell cycle, the chromosome exists in a loose structure, so proteins can be TRANSLATED from the DNA and the DNA can be replicated.2)MITOCHONDRIA are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in NUTRIENTS, breaks them down, and creates ENERGY rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.3)Cytoplasm, the semifluid substance of a cell that is external to the nuclear membrane and internal to the cellular membrane, sometimes described as the nonnuclear content of protoplasm. In eukaryotes (i.e., cells having a nucleus), the cytoplasm contains all of the organelles.4)nuclei is the small, dense center of the atom. The nucleus is composed of protons and neutrons and has a positive electrical charge.

he primary organs of the respiratory system are the lungs, which function to take in oxygen and expel carbon dioxide as we breathe.The gas exchange process is performed by the lungs and respiratory system. Air, a mix of oxygen and other gases, is inhaled.In the throat, the trachea, or windpipe, filters the air. The trachea branches into two bronchi, tubes that lead to the lungs.Once in the lungs, oxygen is moved into the bloodstream. Blood carries the oxygen through the body to where it is needed.Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs.An exchange of oxygen and carbon dioxide takes place in the alveoli, small structures within the lungs. The carbon dioxide, a waste gas, is exhaled and the CYCLE begins again with the next breath.The diaphragm is a dome-shaped muscle below the lungs that CONTROLS breathing. The diaphragm flattens out and pulls forward, drawing air into the lungs for inhalation. During exhalation the diaphragm expands to force air out of the lungs.Adults normally take 12 to 20 breaths PER minute. Strenuous EXERCISE drives the breath RATE up to an average of 45 breaths per minute.

tion:Significance of MitosisIt is responsible for the growth and development of an individual. It maintains the constant number of chromosomes in all body cells of an organism. Mitosis is required for asexual reproduction, vegetative propagation in PLANTS and also responsible for repair and REGENERATION of damaged TISSUES.

tion:LICHEN is an organism that is formed by the SYMBIOTIC association of a fungus and an alga or CYANOBACTERIUM and occurs as crusty patches or bushy growths on tree trunks, bare ground, etc. . The fungus surrounds the algal cells, often enclosing them within COMPLEX fungal TISSUES unique to lichen associations.

Classification of ProtistaKingdom Protista is classified into the following:ProtozoaProtozoans are unicellular organisms. Historically, protozoans were called “animal” protists as they are heterotrophic, and showed animal-like behaviours.There are also parasitic protozoans which live in the cells of larger organisms. Most of the members do not have a predefined shape. For instance, an amoeba can change its shape indefinitely but a paramecium has a definite slipper-like shape. The most well-known examples of protozoans are amoeba, paramecium, euglena. Unlike other members of this group, euglena is a free-living protozoan that has chlorophyll, which means it can make its own food.The protozoans can be divided into four major groups:AMOEBOID protozoans – MOSTLY found in water bodies, either fresh or saline. They have pseudopodia (false feet) which help to change their shape and in capturing and engulfing food. E.g. AmoebaFlagellated protozoans – As the name suggests, the members of this group have flagella. They can be free-living as well as parasitic. E.g. EuglenaCiliated protozoans – They have cilia all over their body which help in LOCOMOTION as well as nutrition. They are ALWAYS aquatic. E.g. ParameciumSporozoans – These organisms are so-called because their life cycle has a spore-like stage. For example, the malarial parasite, Plasmodium.Explanation:please do follow me.

The FOUNDATION of BIOLOGY as it exists today is based on five basic PRINCIPLES. They are the cell theory, gene theory, evolution, homeostasis, and laws of thermodynamics. Cell Theory: all LIVING ORGANISMS are composed of cells.

The structure of neuron: Nerve cells or neurons are the structural and FUNCTIONAL units of the nervous system. It CONSISTS of three major PARTS namely, Cell body, dendrites, Axon. Cell Body: It is irregular in shape or polyhedral. The cell body contains cytoplasm and certain granular bodies called Nissles granules which contain a group of RIBOSOMES for protein synthesis. Dendrites: Dendrites are short fibres which branch repeatedly and protrude out of the cell body. They transmit electrical impulse towards the cyton. Axon: They are long fibres arising from the cell body with the branched distal end. It terminates in bulb-like structures called synaptic knob. It is filled with chemicals called neurotransmitters. Parts of Axon:  a. Axoplasm: It is the cytoplasm of the axon. b. Myelin sheath: It is made up of many layers of Schwann cells. C. Neurilemma: The outermost layer of Schwann cells. d. Nodes of Ranvier: These are gaps left by a myelin sheath.Explanation:

Because if the CELL WALL will present then the surface will be the rigid and HARD and no ANIMAL have rigid and hard surface

but when we talk about the GERM cell that is the pollen grain of the diploid organism which is the onion plant the chromosome number REDUCES to half by MEIOSIS REDUCTION DIVISION. hence the number of chromosomes their present will be eight only

I............. .....

tion:Synapsis (also called SYNDESIS) is the PAIRING of two homologous chromosomes that occurs during MEIOSIS. It allows matching-up of homologous pairs prior to their segregation, and POSSIBLE chromosomal crossover between them. Synapsis TAKES place during prophase I of meiosis.

tion:Annelida and ArthropodaThe CLOSED CIRCULATORY system PUMPS BLOOD throughout the length of the worm's body. Annelids generally have a well-developed body cavity, an excretory system, and a nervous system with a primitive BRAIN.

ion growth is based on FOUR FUNDAMENTAL FACTORS: birth rate, death rate, immigration, and EMIGRATION.

in Hydra Binary fission in Amoeba Asexual reproduction in which a NEW organism DEVELOPS from a BUD in the parent. It is the type of asexual reproduction in which the parent divides to give rise to two daughter organisms.This bud is simply an outgrowth of cells at one particular site. The parent REPLICATES its genetic material and divides it equally between the two daughters.The bud or the new organism remains attached to the parent and gets detached on maturation. Both the CYTOPLASM and the nucleus of the parent divides into two.

which LANGUAGE is it????

tion:Some PLANTS develop adventitious buds on their leaves which get detached and develop new plants. Leaves of Bryophyllum develop SMALL plantlets with adventitious roots ALONG their margins. These get detached and give rise to a complete plant. Thus it is a natural method of vegetative propagation in this plant with the help of leaves. Leaves of some other plants such as Kalanchoe, Begonia and Streptocarpus also develop adventitious buds in their leaves. In some plants such as tapioca, SWEET potato buds present on the roots develop into leafy shoots above ground and adventitious roots at their bases. Vegetative propagation by stem takes place in mint, onion, garlic, banana ETC.

tion:The golgi apparatus is a membrane BOUND ORGANELLE found in most cells. It is responsible for packaging proteins into VESICLES prior to secretion and therefore plays a key role in the SECRETORY pathway.

ITS TRANSPORT FOOD FROM THE LEAVES. TAKING in SUNLIGHT is done by the leaves transporting WATER from the ROOTS to the leaves is done by XYLEM vessels not phloem

PseudocoelomExplanation:Pseudocoelom is a false body CAVITY that is not lined with mesodermal cells. It is FOUND in organisms such as nematodes. COELOM in annelids is schizocoelom that develops from a split in the mesoderm. Therefore, pseudocoelom is not a CHARACTERISTIC of ANNELIDA. So, the correct option is 'Pseudocoelom'.
