Levels of biological organization

Levels of biological organizations
The study of biology at different levels is called biological organizations.
Biological level starts from the very basic level of sub-atomic and atomic particles to the organisms itself .After that community population and entire world are studied.

1 Atomic and sub atomic level

All the living and non living organisms are made up of atoms.these atoms are composed of subatomic particles like proton electron and neutron.

2.
Molecular level

The atoms combine with each other to form molecules.molecules are formed by ionic or covalent bonds.most of the biological molecules contain hydrogen carbon Nitrogen,Phosphorus and sulphur.there are two types of biological may lecules

A.Micromolecules

They have low molecular weight.like CO2, H2O etc

B.Macromolecules

They have high molecular weight like starch,protein etc

*Organic molecules

Contain both carbon and hydrogen together are called organic molecules

*inorganic molecules

Without carbon and hydrogen together are called inorganic molecules.
An organism is made up of a large number of different types of micro and macromolecules.some of theses molecules are glucose,amino acids,fatty acids,glycerol, and nucleotides like ATP,ADP,and AMP etc

Neurotransmitters and receptors

Image
Neurotransmitters and receptors Did you know there are billions of neurons—and trillions of synapses—in your amazing brain? ^1 1 start superscript, 1, end superscript  (No wonder you can learn anything, including neurobiology!) Most of your synapses are  chemical synapses , meaning that information is carried by chemical messengers from one neuron to the next. In the article on synapses, we discussed how synaptic transmission works. Here, we’ll focus on  neurotransmitters , the chemical messengers released from neurons at synapses so that they can “talk” to neighboring cells. We’ll also look at the receptor proteins that let the target cell “hear” the message. Neurotransmitters: Conventional and unconventional There are many different kinds of neurotransmitters, and new ones are still being discovered! Over the years, the very idea of what makes something a neurotransmitter has changed and broadened. Because the definition has expanded, some recently discovered n

The Importance of Animal Physiology

The Importance of  Animal Physiology Why is the study of animal physiology important to you and to people in general? Not the least of the reasons is the one we have already emphasized—namely, that a full understanding and appreciation of all the marvels and other phenomena of the animal world depends on an analysis of how animals work. The study of physiology draws us beyond surface impressions into the inner workings of animals, and nearly always this venture is not only a voyage of discovery, but also one of revelation. The study of physiology also has enormous practical applications because physiology is a principal discipline in the understanding of health and disease. The analysis of many human diseases—ranging from aching joints to heart failure—depends on understanding how the “human machine” works. A physician who studies heart disease, for instance, needs to know the forces that make blood flow into the heart chambers between one heartbeat and the next. The physician also

What are chromosomes?

Image
Chromosome Chromosome During cell division the chromatin material change into thread like structure called chromosome. Chromosomes are also called physical basis of hereditary. On the chromosomes small bodies are located call genes. There are thousands of genes are present in an organisms.Genes are the unit of heredity. These genes contain hereditary character which are transfered from one generation to another by the help of chromosomes. Chromosomes were discovered by a biologist waldyer in 1876. After that in  1908 Sutton identified the function of chromosomes,that they take part in the transfer of hereditary characters.      ( Next post will be about Structure of chromosomes)
