.Moderngenetic manipulationinvolves scientific procedures to add new DNA to or silencegenesequences in an organism. .Genetic manipulationis, in essence, a process done tomanipulatethe genome of an organism in order to produce desired traits. In the past, this was achieved by selective breeding.

Genetic manipulationis a process where the gene for a particular character is introduced inside the chromosome of a cell. When the gene for a particular character is introduced in a plant cell, a transgenic plant is produced. These transgenic plants exhibit characters governed by the newly introduced gene

genetics is the branch of science that deals with the study of heredity and inheritance of traits from parents to their offsprings. evolution is the process in which organisms change or modifie themselves for better survival.

Genetic manipulation is a process in which genes of desirable characters are taken from a plant and transferred to another plant by the technique of hybridisation.

.Genetic manipulation helps in obtaining desirable agronomic characters liked Dwarfness in cereals and tallness and profuse branching in fodder crops.

.It is useful in developing varieties with higher yield, good quality, biotic and abiotic resistance, short maturity period, wider adoptability and desirable agronomic characteristics.

thank you a lot

Coenzymes are small molecules which cannot by themselves catalyze a reaction but they can help enzymes to do so.coenzymes are organic nonprotein molecules that bind with the protein molecule to form the active enzyme.

i) Terrace cultivation :-Terrace cultivation is the method of growing crops on sides of hills, mountains and steep slopes by planting on graduated terraces built into the slope.

"the study of the mechanisms of temporal and spatial control of gene activity during the development of complex organisms." Thusepigeneticcan be used to describe anything other than DNA sequence that influences the development of an organism.

Reproductive health is a state of complete physical, mental and social well-being, and not merely the absence of reproductive disease or infirmity. Reproductive health deals with the reproductive processes, functions and system at all stages of life.

It's not advisable to do any kind of such activities. and practically it varies from person to person. but still as the child is minor , it is advisable to do anything under supervision of parents.

Ans :- Option (a) Drosera is correct.

Chemonastic movements: The tentacles of Drosera are also stimulated by ammonium salts, phosphates or a drop of water containing proteins. Therefore. tentacle of Drosera also shows chemonastic movements. The one of the sixsensitive hairs on the upper surface of the leaf is stimulated by contact.

Microbes plays an important role in agricultural management because they help to fix the nitrogen by nitrogen fixation which helps the plants to absorb nitrogen easily. and they also helps to decompose the dead and organic matter which is also very useful for plants.

Mint is an example of stolon.

Stolon is a modification of stem which is also known as runner. These are horizontally oriented stem that grow along the soil surface giving rise to roots and aerial branches. E.g.Mentha sp.(mint).

Mint plant reproduces both vegetatively and through seeds. Vegetatively they reproduce by runners or stolons, which produce new roots and shoots at the nodes, in the presence of favourable conditions.

mint is a plant which undergo stolon type of vegetative reproduction.

a new set of roots develop from the node when it Ben's and touch to the soil.

DNA replication is the process of copying the DNA within our cells.The first step in DNA replication is to 'unzip' the double helix structure of the DNA molecule.

In 1958, theMeselson-Stahlexperiment proved that in bacteria DNA replication was semi- conservative.

Difference Between Mosses and Ferns

Definition

Mosses:Mosses are small, nonvascular plants that do not have a true root, stem, and leaves and reproduce by the production of spores in stalked capsules.

Ferns:Ferns are flowerless, vascular plants with leafy fronds that mainly reproduce by the production of spores.

Belong to

Mosses:Mosses belong to the phylum Bryophyta.

Ferns:Ferns belong to the phylum Pteridophyta.

Vascular/Non-vascular Plants

Mosses:Mosses are non-vascular plants.

Ferns:Ferns are vascular plants.

Leaves

Mosses:Mosses consist of a lot of leaflets.

Ferns:Ferns consist of true leaves and stems.

Roots

Mosses:Mosses contains multicellular rhizoids.

Ferns:Ferns contains true roots.

Viviparous animals give birth to offspring instead of laying eggs (called oviparity). Viviparous animals can be found in most all classes of vertebrates and are common to most mammals. Mammals: most including human, but not those laying eggs;

Fossils are the remains or preserved traces of dead plants or animals, which died millions of years ago and some of them are already extinct. The remains or impressions of body part, sometime can be found between different layers of earth under its surface. The study of fossils have helped us to know about the evolution or the link between two species. Fossils tells us how new species are developed from the old. So fossils have an importance in deciding evolutionary relationship.

Pollinationis the act of transferring pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, including plants, is to create offspring for the next generation. One of the ways that plants can produce offspring is by making seeds.

1)Resting potential, the imbalance of electrical charge that exists between the interior of electrically excitable neurons (nerve cells) and their surroundings. ... If the inside of the cell becomes less negative (i.e., thepotential decreases below theresting potential), the process is called depolarization.

2)Action Potential. The resting potential tells about what happens when a neuron is at rest. An action potential occurs when a neuron sends information down an axon, away from the cell body. Neuroscientists use other words, such as a "spike" or an "impulse" for the action potential.

Pollination is the term used to define the transfer of pollen from the male part of the flower, the stamen, to the female part of the flower, the pistil.

HUMANS HAVE AN IMPORTANT ROLE IN OUR ENVIRONMENT.

Croprotation is the practice ofgrowinga series of dissimilar ordifferenttypes ofcropsin thesame areain sequenced seasons. It is done so that thesoilof farms is not used for only one set of nutrients.

Geotropism is the influence of gravity on plant growth or movement. Geotropism guides plant roots to grown downward, or if growing horizontally in shallow topsoil, to occasionally branch and send some roots vertically downward.

Every organism lives by taking nutrition and for a plant to live. minerals and water is necessary.... so to get minerals (as water &minerals are deeper in earth)and water geotropism is done by plants

Geotropism is the growth of an organ in plant under the influence gravitational pull of the earth. Roots exhibit positive geotropism as they grow towards soil. Gravitropism (also known as geotropism) is a turning or growth movement by a plant, fungus, or animal in response to gravity.

colourless unstable toxic gas with a pungent odour and powerful oxidizing properties, formed from oxygen by electrical discharges or ultraviolet light. It differs from normal oxygen (O2) in having three atoms in its molecule (O3).

The root of the plant will show positive geotropism while the shoot of the plant will show negative geotropism.

The root of the plant will show positive geotropism while the shoot will show negative geotropism. The growth of the parts of plants in response to the force of gravity is called the geotropism of the plant. It is the directional growth of an organism in response to gravity.

The word “flora” is used to designate plant life. The word “flora” is derived from the Latin name of Flora, the goddess of plants, flowers. In Roman mythology, Flora epitomised the goddess of flowers and of the season of spring. Flora was a symbol of nature and flowers and fertility in Roman mythology.Fauna is all of the animal life. Fauna’s name derived from “to favour, nurture,” because it was believed by the ancient Roman religion that Fauna is the goddess who nurtures all that is useful to living creatures.

Flora and fauna mean plants and animals. These two forms of life along with other life forms constitute a biota.
