Answer:

•Biodiversity refers to variability.

•   The diverse forms of organism need classification

.•   The evolutionary history decides the phylogenetic classification.

•   H. Whittaker proposed the five kingdom system of classification

•   A distinct name is a need for identification.

•   Common names are unscientific.

•   Binomial nomenclature is scientific naming of organisms.

•   Taxonomic hierarchy is the framework of classification which helps in appropriate placing of organisms.

1. Monera•   These are prokaryotic, UNICELLULAR, autotrophic or heterotropic organisms.

2. Protista•   These are unicellular and eukaryotic, autotrophic or heterotrophic organisms.

•   They are further classified as protistan algae, slimemoulds, and protozoa.

3. Fungi•   Multicellular and eukaryotic organisms having plant like and animal like features. They may be parasitic or saprophytic.

4. Plantae•   These are multicellular, eukaryotic and autotrophic organisms. They are further classified.

•   Thallophyta – Thallus like body, mostly autotrophic and aquatic.

•   Bryophyta – Simple plants with no vascular system. They are amphibious.

•   Pteridophytes – They are land plants with true vascular system.

•   Gymnosperms – They are land plants bearing NAKED SEEDS.

•   Angiosperms – They are flowering plants with seeds covered by fruits.

5. Animalia•   These are multicellular, eukaryotic and heterotrophic organisms. They are further classified.

•   Porifera – PORE bearing organisms.

•   Coelenterata – Organisms with hollow gut

.•   Platyhelminthes – unsegmented flat worms.

•   Nematoda – Unsegmented round worms.

•   Annelida – Metamerically segmented worms.

•   Arthropoda – These are animals with jointed appendages.

•   Mollusca – Soft bodied animals.

•   Echinodermata – SPINY skinned animals.

•   Chordata – Dorsal nerve cord, notochord and gill slits.

Answer:

A new species of bacteria has been discovered on a man in Cornwall. The bacteria was found on a 64 year old man seeking TREATMENT for cellulitis. When researchers attempted to find the cause of this skin infection, they found the bacteria, which although similar to others, had not been seen before

Researchers named the new species Staphylococcus cornubiensis after the medieval name for Cornwall, Cornubia.

The discovery of S. cornubiensis was reported in the International Journal of Systematic and Evolutionary Microbiology along with evidence that this is a new species.

Lead author Dr Aimee Murray said: “We now need to KNOW how prevalent this new species is in human infections. As some related species are transferred from pets to humans, we also would like to find out whether owning pets, or any other potential risk factors, increase the chance of infection.”

After collecting S. cornubiensis from the skin infection, researchers at the University of Exeter MEDICAL School and the Royal Cornwall Hospital found that it had not been reported before. They think it is part of a group of bacteria known as the Staphylococcus intermedius group (SIG). This is a group of harmful bacteria which are usually passed onto humans from pet dogs.

The SIG group of bacteria contains bacterial species Staphylococcus intermedius and Staphylococcus pseudointermedius, which have been identified as potential zoonotic threats, meaning there is a risk of these bacteria spreading to humans from animals and causing infection.

If an infection is severe, bacteria in the SIG group are usually treated using antibiotics, however resistance to common antibiotics is INCREASING in this bacterial group. Severe infections usually only occur in patients with weakened immune systems, making them more susceptible and less likely to fight off the infection.

According to Doctors John Lee and Richard Bendall, the strain was discovered as the result of a project conducted at the Royal Cornwall Hospital. The hospital HOPES to increase recognition and detection of bacterial infections caused by the SIG group.

Answer:

• In the human heart, contraction is initiated by a special modified heart muscle known as sinoatrial node.
• It is located in the RIGHT atrium. The SA node has the inherent power of GENERATING a wave of contraction and controlling the heart beat.
• Hence, it is known as the pacemaker. Since the heart beat is initiated by the SA node and the impulse of contraction ORIGINATES in the heart itself, the human heart is termed myogenic.
• The HEARTS of vertebrates and molluscs are also myogenic

Explanation:What is Parasitism?

Parasitism is GENERALLY defined as a symbiotic relationship between the two living SPECIES. In this relationship, the parasites gain complete benefits from the host cell in which they are living by causing harm to the host’s cells. The word parasite is derived from the Latin form of the Greek word, meaning “one who eats at the table of another”.

A few examples of parasites are TAPEWORMS, fleas, and BARNACLES. Tapeworms are segmented flatworms that attach themselves to the insides of the intestines of animals such as cows, pigs, and humans. They get food by eating the host’s partly digested food, depriving the host of nutrients.

Types of Parasitism

There are various types of parasitism and are classifications based on their size, characteristics, interactions with their hosts and on their life cycles.

Based on Interaction with host, these are the following types of Parasites

Endoparasites: Parasites that live inside the body of the host are called endoparasites.

Ectoparasites: Parasites that live outside are called ectoparasites.

Epiparasite: Parasites that feed on other parasites are called epiparasite.

Meso Parasites: Parasites living in an intermediate position, being half-ectoparasites and half-endoparasites, are called meso parasites.  

Based on their Life Cycle

Obligate Parasite: Parasites which are completely dependent on the host to complete its life cycle.

Facultative Parasite: Parasites which are dependent but not completely on the host to complete its life cycle.

Social parasites do not directly feed on the tissue of their hosts like true parasites instead they gain benefit from their host by convincing the host to provide food or other benefits.

A good example of a social parasite occurs when there are generalised non-specific mutualisms between classes of ORGANISMS. For example, some plants can behave as “mycorrhizal cheaters”, establishing mycorrhiza-like interactions with a fungal symbiont, but taking carbon from the fungus (which the fungus, in turn, gets from other plants) rather than donating carbon. Another example is the cuckoo bird which leaves its young with a host to raise. This type of parasitism is often called brood parasitism.

Parasitism Dynamics: Due to the nature of the interaction between a host and a parasite many host populations will develop some form of immunity. The development of host population immunity causes either a decline in the parasite population or a genetic mutation in the parasite population to overcome the immunity. This dynamic tends to form a cycle in the parasite population where there are periods of population increases and periods of population decreases.

Advantages and Disadvantages of Parasitism

The host of a parasite gets no advantages. If it did, then the relationship would be mutualistic not parasitic. If one gets advantage and the other is relatively unaffected then the relationship is commensal. Some plants are parasitic (i.e. Mistletoe) and other plants are parasitized.

Many human diseases are caused by parasites (malaria, sleeping sickness etc) so this is clearly a disadvantage but humans can use parasites to their benefit. Many biological controls involve the use of parasites. In short, a parasite is a disadvantage to its host but may play a number of other roles within the ecosystem.

Many parasites cause harmful effects on their host. Such effects comprise:

Wasting

Allergic reactions

Mechanical damage

Irritative reflexes (intestinal contractions: ascaris)

To conclude about parasitism, it is evident that parasitism has very little to offer in terms of benefits. But yes, It helps maintain biodiversity in the ecosystem and controls the population to a large extent. Parasite-host interactions may be important at times. For example, such as parasitoids controlling the body temperatures of their hosts in order to ensure the survival of their offspring, and host choice in fleas being controlled by the off-host environment.

Hope your doubt is cleared.

Explanation:

Mitosis vs. Meiosis: Overview and commonly asked questions

Mitosis

Meiosis

What is the purpose of this process?

In a unicellular organism, the purpose of mitosis is to proliferate asa species. In a multicellular organism, the purpose can be to grow during development, or to repair or regenerate  

adamaged tissue, for example.

To create gametes with only one copy of the organism’s genetic information, in preparation for sexual reproduction. Various steps in meiosis create opportunity for genetic diversity in the daughter cells. This is the raw substrate for evolution.

What is the outcome of this process?

Two diploid cells with identical genetic information.

Four haploid cells with different genetic information.

Which organisms perform this process?

Mitosis is performed by unicellular and multicellular eukaryotes.Bacteria have their own version of mitosis called “binary fission”.This is distinct from meiosis as bacteria typically have one circular chromosome,which is not contained within a nucleus, like eukaryotic chromosomes.

Only organisms which perform sexual reproduction. Archaeaand bacteria do not do this, so it might be tempting to think that unicellularorganisms do not sexually reproduce. However, there are exceptions; buddingyeast will form haploid spores under NUTRITIONAL deprivation.        

How long does this process take?

Mitosis is USUALLY shorter than meiosis. The process can take over 10 hours for mammalian cells in culture [2], budding yeast can take ~80 minutes to complete a cell cycle [3], whilst bacteria can divide every 20 minutes.

Meiosis has various timescales in different organisms, which can be affected by several factors including temperature and environment of the organism, and the amount of nuclear DNA. The process lasts 6 hours in yeast but can last more than 40 years in human females, due to a developmental hold at prophase I, until ovulation. Other examples are 1-2 days in male fruit flies and ~ 24 days in human males. [1]

What is an example of a disease caused by an error in this process?

Uncontrolled mitosis occurs in cancer, where either genes that stop cell division (tumour suppressors) are switched off, or genes that encourage cell division (oncogenes) are overactive.

Errors in meiosis can lead to the wrong number of chromosomes ending up in germ cells, this is called aneuploidy. This can trigger miscarriage, but is occasionally tolerated. One example is Down’s syndrome, caused by trisomy 21. Another example is Klinefelter syndrome, where XY males have an additional X chromosome.

Etymology?

Mitosis is the Greek word for thread, after the thread-like chromosomes that can be seen under the microscope in dye-stained cells during cell division.

Meiosis MEANS a “lessening” in Greek. This refers to the outcome of meiosis, where the genetic information in each new cell is halved.

First described by?

Walther Flemming in his 1882 work “Cell substance, nucleus and cell division.” [5]

Oskar Hertwig described the fusion of egg and sperm in the transparent sea urchin egg in 1876. [4]

Setting the scene for mitosis vs. meiosis

Cell division occurs as a part of the “cell cycle”. Just like your day has a routine from day to night, cells have routines of their own. The cell cycle is generally described as consisting of four MAIN phases: G1, S phase, G2 and mitosis (or meiosis). Cells can also take a break from the grind of the cell cycle, in a state called G0 or senescence (note that some cells are permanently in G0). External growth factors can stimulate cells in G1 or G0 to proceed through the rest of the cycle, an example is Nerve Growth Factor (NGF), which promotes neuron growth. The restriction point is a special “point of no return” in G1 when cells no longer respond to removal of growth factors and will continue to progress to S phase no matter what. There are also internal signals that tell the cell to progress, these proteins are called cyclins and the cyclin that promotes mitosis is called cyclin B. S phase is especially important as this is the point at which the cell’s entire genome is duplicated through the process of semi-conservative DNA replication.

Answer:

the main difference is that in RESPIRATION we TAKE OXYGEN and release or exhale carbon dioxide and in photosynthesis PLANTS take CO2 and release oxygen.

Answer:

mitochondria is the powerhouse of the CELL USE this POWER when NECESSARY ATP molecule

Answer:

We use sprouted seed to demonstrate that CO2 is liberated during RESPIRATION but not green plants... because in green plants both respiration and photosynthesis TAKES PLACE which is difficult to demonstrate....as respiration and photosynthesis occur simultaneously......which confuses us whether th Co2 liberated during respiration or photosynthesis,where as in sprouts primilarly respiration takesplace...and so sprouted SEEDS are used...
