The DIGESTIVE system of frog has digestive tract and the accessory organs which help to process the food consumed into small molecules (nutrients) which then can be easily absorbed and then utilized by the cells of the body.

Parts of the digestive system of a frog includes:

Mouth
Pharynx
Oesophagus
Stomach
Small intestine
Large intestine
Cloaca
Accessory organs
Characteristics of Frog’s digestive system:

Frogs have maxillary teeth along their upper JAW which are used to hold food before it is SWALLOWED. These teeth are very weak, and cannot be used to chew or catch and harm agile prey.
The frog uses its sticky, cleft tongue to catch flies and other small moving prey. The tongue normally lies coiled in the mouth, free at the back and attached to the mandible at the front. It can be shot out and retracted at great speed.
Some frogs have no tongue and just stuff food into their mouths with their hands.
The eyes assist in the swallowing of food as they can be retracted through holes in the SKULL and help push food down the throat.
The food then moves through the oesophagus into the stomach where digestive enzymes are added and it is churned up. It then proceeds to the small intestine (duodenum and ileum) where most digestion occurs. Pancreatic juice from the pancreas, and bile, produced by the LIVER and stored in the gallbladder, are secreted into the small intestine, where the fluids digest the food and the nutrients are absorbed. The food residue passes into the large intestine where excess water is removed and the wastes are passed out through the cloca.

One of the most highly produced inorganic chemicals. There are NUMEROUS large-scale ammonia PRODUCTION PLANTS worldwide, producing a total of 131 million tonnes of nitrogen (equivalent to 159 million tonnes of ammonia) in 2010. China produced 32.1% of the worldwide production, followed by India with 8.9%, Russia with 7.9%, and the United States with 6.3%. 80% or more of the ammonia produced is used for fertilizing agricultural crops. Ammonia is also used for the production of plastics, FIBERS, explosives, nitric acid (via the Ostwald process) and intermediates for DYES and pharmaceuticals.

Since the reproduction is asexual, the NEWLY CREATED organism is a clone and is genetically identical to the parent organism. Organisms such as hydrause regenerative cells for reproduction in the PROCESS of budding. In hydra, a bud develops as an outgrowth DUE to repeated cell division at one specific site.

Structurally, PLANT and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound ORGANELLES such as the NUCLEUS, mitochondria, endoplasmic RETICULUM, golgi apparatus, lysosomes, and peroxisomes.

ASEXUAL reproduction takes place in paslmodium via MULTIPLE binary fission in which a single parent cell give birth to many tamets or daughter cells. 

@ vegetative propagation iskind of reproduction in which new plantis grown from vegetative part (all part of plant other than flower becauseit is a reproductivepart.)of the plant.

@ DNA present inside the nucleus of the cell.it is known as chromosomal DNA. it is also present in Mitrochrondria cell.

@Prostate gland & seminal vesicles are the accessory glands of male reproductive system. They secrete fluid known as semen which contains sperms. This fluid makes transport of sperms easier and also provides nutrition to sperms.

@The ovary releases one egg every month. The uterus also prepares itself every month to receive a fertilized egg. The inner uterus lining (endometrium) becomes thick and is supplied with blood to nourish the embryo. If the egg is not fertilized, then the uterus lining is not required. Hence, it breaks down and is released in the form of blood and MUCUS through the vagina. This process lasts for 2-8 days. This cycle occurs every month and is known as menstruation. Hence, the MENSTRUAL cycle is the reproductive cycle in the female body. It begins with the ONSET of puberty.

I THINK EARTH is itself the largest structure made up of LIVING organisms.

When genes are found on different CHROMOSOMES or far apart on the same chromosome, they assort independently and are said to be unlinked.

When genes are close together on the same chromosome, they are said to be linked. That means the alleles, or gene VERSIONS, already together on one chromosome will be inherited as a unit more frequently than not.

We can see if two genes are linked, and how tightly, by using data from GENETIC crosses to calculate the recombination frequency.

By finding recombination frequencies for many gene pairs, we can make LINKAGE maps that show the order and relative distances of the genes on the chromosome.

Reusing is better than RECYCLING because
1) We cannot recycle all TYPES of plastic.
2) We can reuse things whch are in good condition.

The ANSWER is 1.......

basis of natural system of classification are:-

Kingdom

When Linnaeus first described his system, he named only TWO kingdoms – animals and plants. Today, scientists think there are at least five kingdoms – animals, plants, fungi, protists (very simple organisms) and monera (bacteria). Some scientists now support the idea of a sixth kingdom – viruses – but this is being contested and argued around the world.

Phylum

Below the kingdom is the phylum (plural phyla). Within the animal kingdom, major phyla include chordata (animals with a backbone), arthropoda (includes insects) and mollusca (molluscs such as snails). Phyla have also been developed and reorganised since the original work by Linnaeus – as scientists discover more species, more categories and subcategories are put in place.

Class

Each phylum is then divided into classes. Classes within the chordata phylum include mammalia (mammals), reptilia (reptiles) and osteichthyes (fish), among others.

Order

The class will then be subdivided into an order. Within the class mammalia, examples of an order include cetacea (including whales and dolphins), carnivora (carnivores), primates (monkeys, apes and humans) and chiroptera (bats).

Family

From the order, the organism will be classified into a family. Within the order of primates, families include hominidae (great apes and humans), cercopithecidae (old world monkeys such as BABOONS) and hylobatidae (gibbons and lesser apes).

Genus and species

Finally, the classification will come to the genus (plural genera) and species. These are the names that are most commonly used to describe an organism. One outstanding feature of the Linnean classification system is that two names are generally sufficient to differentiate from one organism to the next. An example within the primate family is the genus Homo for all human species (for example, Homo sapiens) or Pongo for the genus of orangutan (for example, Pongo abelii for the Sumatran orangutan or Pongo pygmaeus for the BORNEAN orangutan).

Constant evolution

While this system of classification has existed for over 300 years, it is constantly evolving. Classification in the 1700s was based entirely on the morphological characteristics (what something looks like) of the organism. Those that looked most alike were put CLOSEST together in each category. This can be depicted as a tree, with the diverging branches showing how DIFFERENT the species become as you move out from the kingdoms (trunk).

Hlo mate

It is a system of classification which TAKES into CONSIDERATION comparable study of a number of characters so as to bring out natural similarities and dissimilarities and HENCE natural relationships among the organisms.

The system employs those characters which are relatively constant. They include morphological characters, ANATOMICAL characters, cytological characters, physiology, ontogeny or development, reproduction, cytochemistry and bio­chemistry, experimental taxonomy, etc.

Seed development culminates in programmed cell death (PCD) and hardening of organs enclosing the embryo (e.g., pericarp, seed coat) providing essentially a physical SHIELD for protection during STORAGE in the soil. We examined the proposal that dead organs enclosing embryos are unique entities that store and release upon hydration ACTIVE proteins that might increase seed persistence in soil, germination and seedling establishment. Proteome ANALYSES of dead seed coats of Brassicaceae species revealed hundreds of proteins being STORED in the seed coat and released upon hydration, many are stress-associated proteins such as nucleases, proteases and chitinases. Functional analysis revealed that dead seed coats function as long-term storage for multiple active hydrolytic enzymes (e.g., nucleases) that can persist in active forms for decades. Substances released from the dead seed coat of the annual desert plant Anastatica hierochuntica displayed strong antimicrobial activity. Our data highlighted a previously unrecognized feature of dead organs enclosing embryos (e.g., seed coat) functioning not only as a physical shield for embryo protection but also as a long-term storage for active proteins and other substances that are released upon hydration to the “seedsphere” and could contribute to seed persistence in the soil, germination and seedling establishment.
