what are chromosomes, chromosome structure
Hi, today's learning about chromosomes. So let me first define you what are chromosomes ? The chromosome are rod like or cilia like structures which formed by abstract of chromatin fibres during corpuscle analysis and reproduction for candid administration of ancestral material.
A chromosome consists of two agnate accoutrement alleged chromatids. Number of chromosomes, there is a anchored chromosome in anniversary species. In a lot of organisms, chromosome occurs in akin pairs. From anniversary pair, one of the chromosomes belongs to ancestor ancestor while the added belongs to mother parent. Presence of two sets of chromosomes or genomes is alleged diploid (2 n)
The two locations of the chromatids are absorbed to anniversary at a point alleged centromere. The two locations of a chromatid on either ancillary of a centromere are alleged arms.
This is all about chromosomes. Do post your comments.

Some learning about law of conservation of energy:
Now am going to write about law of conservation of energy. So let us start learning with what is law of conservation of energy?
The Law of Conservation of Activity states that "the absolute activity of an abandoned arrangement is conserved or said to be connected over time". It can as well be said that "energy cannot be created or destroyed , but it can be adapted from one anatomy to addition form".
Conservation agency to aftereffect in no net accident of a accurate component. So the law says that there is no accident of activity in any abandoned system. According to the account of the law the absolute activity in the cosmos if anchored and it cannot be decreased or increased. You can also get help from chemistry problems online.
The activity can be adapted from one anatomy to addition anatomy for example: in the agitation of coal, the actinic activity is adapted into chemical energy. The activity either charcoal in one or the added form, but is not absent completely.
This is all about law of conservation of energy. If you have any doubts or comments post it here.

Know about composition of urine:
Today I will give you some learning on formation of urine and urine composition. So let us start learning.
Composition of urine :
An average sized human adult produce 1-2 litres / 24. However, the amount per day varies considerably.Approximately 95% of the volume of normal urine is due to water. An boilerplate sized animal developed aftermath 1-2 litres / 24. However, the bulk per day varies considerably.Approximately 95% of the aggregate of accustomed urine is due to water.
The added apparatus of accustomed urine are the solutes that are attenuated in the baptize basic of the urine. These solutes can be disconnected into two categories according to their actinic structure.They are amoebic atom and asleep ions. Formation of urine involves some steps . Tubular beard is a additional way by which substances are removed from claret and added to tubular fluid.
Hydrogen ions, potassium ions, creatinine, and drugs such as penicillin are some of substances that are confused by alive carriage from claret into distal bizarre tubule.
In end, urine contains (1) substances that accept undergone glomerular filtration but accept not been reabsorbed, and (2) substances that accept undergone tubular secretion.

Natural Resources:
The word resource is used to describe the materials present in large quantities and held in reserve for future use. Natural resources are those which which occur naturally within environments. Many of them are essential for our survival.
Some examples for natural resources are: Air, Water, Minerals etc.
Natural resources are classified in different ways. Mainly there are two types of natural resources, They are:
Nonrenewable natural resources are those which can not be renewed are called nonrenewable natural resources. Nonrenewable natural resources are listed as: Fossil fuels, oil, coal, diamonds etc.

Be aware about causes of environmental pollution:
We always keep on complaining about the problem of pollution but we hardly do anything to stop pollution. Pollution is one of the major causes of global warming and it is gradually killing us and our mother earth. We are well aware of the causes of pollution if we really one to resist pollution, we need to control these causes.
We have to work out together for this.
Looking at the water pollution pictures i get tears in my eyes. When water is such a necessity for our life and it is polluted, how long can we live with the polluted water. Not only water but the air we inhale is polluted. So nothing is pollution free.
In order to save our earth or in one sense save our life, we need to resist pollution. So i will urge you to come forward to resist it. Trees purifies air and so cutting trees are harmful. If we will to stop pollution we can, so why not start it.
You might be thinking me as a social service person but i am not. I am just a common person who is selfish and wants to save oneself and it is only possible with the control of pollution. So save yourself, save your home i.e, mother earth. Join with me and start working to resist pollution.

Know about energy laws:
I thought about writing about what is kinetic energy and potential energy. But then i changed my mind and turned to the law of energy.
Almost all of us have heard about the law of conservation of energy. This law states that energy can neither be created nor destroyed, it can only be transformed. Many experiments were been done in order to prove this law.
We all study about these things earlier in school but somehow going back to these, it refreshes our learning and help us to know the subject better. I hope i have helped you at least to some extent on this law.
Next time i will move to some other concepts of science, till then both you and i will explore more about the laws of energy.

structure of nephron:
This writing will all about the structure of nephron. NEPHRON is the structural and anatomic assemblage of branch and anniversary branch consists of 1.2 actor nephrons.
Anniversary nephrons is composed of a bunch of capillaries,called glomerulus and a tube alleged renal tubule.
The dark end of the tubule which invaginates the glomerular capillaries to anatomy the Malphigian corpuscle is alleged Bowman's capsule. Glomerulus is the bunch of capillaries formed from the afferent arterioles. These are amidst actual carefully by the belly band of Bowman's capsule.
