The evidence for the origin of life from INANIMATE matter, was provided through an experiment, conducted in 1953, by Stanley L. Miller and Harold C. Urey. In experiment, they ASSEMBLED an ATMOSPHERE containing molecules like ammonia, methane and hydrogen sulphide, but no oxygen, over water. This was similar to atmosphere that thought to exist on early earth . This was maintained at a temperature just below 100°C and sparks were passed through the mixture of gases to SIMULATE LIGHTNING. At the end of a week, 15% of the carbon from methane, had been converted to simple compounds of carbon including amino acids which make up protein molecules and support the life in basic form. Thus, amply suggesting that life arose afresh on earth .

The proportion of ethnic minorities among the elderly in the United STATES is increasing. The U.S. Census Bureau ESTIMATES that the proportion of ELDERS who are white and non-Hispanic will decline from 87 percent in 1990 to 67 percent in 2050. As compared to the 1990 Census, the population of Hispanic elders is expected to double in 2010, and will be 11 times greater by 2050. Of the 80.1 million elderly PROJECTED for 2050, 8.4 million (10.4 percent) will be black, as compared to 8 percent of elders in 1990.

As shown in detail in the absorption SPECTRA, chlorophyll absorbs light in the red (LONG wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but REFLECTED, MAKING the plant appear green. Chlorophyll is found in the chloroplasts of plants.

A single variety of crop does not POSSES all the desirable characteristics. It is necessary to improve the crop variety. This is done to GET BETTER varieties of crop with the desired qualities. Two Fundamental APPROACHES are adopted to get the desirable characteristics in a single variety. Some of them are

Hybridization  

Genetic Engineering

Hope you that you understood! and also mabye it is the right answer!

These measures include:

HAND Washing.

Infection control standard, contact, droplet and AIRBORNE precautions.

In ADDITION, many genetic studies and experiments have been conducted on what is known as the “Cinderella” of genetics – Drosophilla  Melanogaster (Fruit FLY). ... Drosophila has been used as model organism right from the beginning of the 20th century, in the very EARLY years of the development of the field of genetics.

There are over 2,500 species of Drosophila and, of these, D. melanogaster is the one that has been extensively exploited for research.

Drosophila is one of the most suitable model systems for genetic work due to its short life cycle of about 10 to 11 days at 22 degree C, and high reproductive POTENTIAL.  It produces a large number of PROGENY, which is required for statistical analysis of the results.

This TYPE of POLLINATION is KNOWN as SELF pollination

The cross explained is a DIHYBRID cross which exhibits simultaneous inheritance of two characters. This is ALSO called as dihybrid inheritance.
Dihybrid inheritance is the experimentation of two characteristics with their four CONTRASTING traits.
For instance, dihybrid inheritance involves a pea PLANT producing axial and violet flowers (AA and WW) crossing with a plant producing terminal and WHITE flowers (aa and ww).
F1 progeny produces axial and violet flowers (A and a, W and w ) in which axial and violet are dominant traits.

Answer:

Genral characteristic

They are eukaryotic and multicellular

Their cells have cellulose walls

Majority have transport system.

They have photosynthesis hence autotrophic.

Reproduction is both asexual and sexual

They show alternation of generation

This kingdom is divided into three divisions namely Bryophyta, Pteridophyta and Spermatphyta.

1. DIVISION Bryophyta

These include mosses and liverworts.

General characteristic

They are thalloids as in liverworts or differentiated into simple-leaf like and stemlike structures

They lack vascular transport system

They contain chlorophyll hence photosynthetic.

They have developed rhizoids for anchoring and absorbing water together with dissolved mineral salts.

Show alternations of generations

Male gametes are produced by antheridia and female gametes by archegonia. Fertilisation depends on availability of water.

They are terrestrial growing on dump substratum eg rocks, walls and marshes

2. Division Pteridophyta

These include the ferns and horsetails. They show a greater variety and a greater ability than bryophyte.

General characteristics

They have roots, stems and leaves but no flowers

Leaves are compound with leaflets known as pinna.

They posses clearly defined vascular system( Having xylem and Phloem)

They show alternation of generations

Sexual reproduction

They have spirongira

Spermatophyta

3. Division Spermatophyta

This division comprises all the seed bearing plants. They are familiar green plants which produce seeds through flowers or cones.

General characteristics

The plant has roots, stems, leaves and seed bearing structures

They produce seeds

They have chlorophyll hence photosynthetic

They have vascular tissue is highly developed with xylem tissue consisting of both xylem tissue and tracheids.

The division SPERMATOPHYTE consists of two main subdivisions:

Gymnospermatophyta

Angiospermatophyta.

Gymnospermatophyta

Characteristics

They bear cones of two TYPES, male and female

After fertilization seeds are not enclosed in a fruit wall.

They show some xerophytic characteristics such as rolled leaves, needle-SHAPED leaves, sunken stomata and thick waxy leaves

Xylem consists mainly tracheids while phloem does not have companion cells.

This subdiviosn has three main classes

Class Coniferales

They include all the common gymnosperms naturally found in areas with little water.

They have needle-like shaped leaves with a thick waxy cuticle

Mature naked seeds occur at bases of female cones some months after pollination

Class Cycadales

Cycadeles resemble palms superficially.

They have long compound leaves which are clustered at the apex of a thick ussualy short and unbranched stems.

They have cones which are borne at the apex of the trunk among leaves.

Class Ginkgoales

Members of this class are very rare. They have deciduous with fan-like leaves. Examples include Ginkgo biloba species in china

2. Angiospermatophyta.

This is the most advanced group found almost everywhere. They include grasses, herbs, shrubs and trees.

Characteristics

They are flower bearing and are usually bisexual.

Seeds are enclosed in an ovary which develops into a fruit.

Xylem has tracheids and vessels while phloem has companion cells.

They exhibit double fertilization.

This group is divided into Two Classes

a) Class Dicotyledonae

These are plant whose embryo of seeds has two cotyledons.

Their leaves are broad and have networks of veins

Cross section of stems REVEALS vascular bundles arranged in rings

They have taproot system

Centrally placed star-shaped xylem with phloem alternating with arms of the xylem

Their flowers have floral parts in five or fours

Examples are herbs, shrubs, and trees. The herbs include plants with all stems such as beans, cabbages, tomatoes and black jack while the shrubs include plants with fairly thick stems such as coffee, tea and cocoa

b) Class Monocotyledonae

Their seeds have an embryo with one cotyledon

Relatively narrow leaves with parallel veins

The cross section of the stem reveals scattered vascular veins

No vascular cambium hence no secondary growth

Viruses are the smallest biological particle (the tiniest are only 20 nm in diameter). However, they are not biological organisms so they are not CLASSIFIED in any kingdom of living things. They do not have any ORGANELLES and cannot respire or perform metabolic functions. Viruses are MERELY strands of DNA or RNA surrounded by a protective PROTEIN coat called a capsid. Viruses only come to life when they have invaded a cell. Outside of a host cell, viruses are completely inert.

Algae and fungi both are EUKARYOTIC organisms, which are classified under kingdom Protistaand kingdom Fungi. Kingdom Protista contains protozoans and MOLDS in addition to algae. Algae play a VITAL role in ecosystems as primary producers and producers of oxygen GASSES. Fungi grow as chains of cells called fungal hyphae. Both algae and fungi form thallus. The main difference between algae and fungi is that algae are autotrophs, containing chlorophyllsfor photosynthesis whereas fungi are heterotrophs, obtaining organic material from the sources in the external environment...

Cells are self duplicating , self-contained UNITS and some cells are totipotent .
Totipotency: (totus_entire,potential_power)
it is capacity or the POTENTIAL of living nucleated cell to differentiate into any other type of cell and thus can FORM a complete NEW organisms.

Decomposition in plants. The PRIMARY decomposers of most dead plant MATERIAL are fungi. Dead LEAVES fall from trees and herbaceous plants collapse to the ground after they have produced seeds, forming a layer of litter on the soil SURFACE.
