The first law of thermodynamics defines the internal energy (E) as equal to the difference of the heat transfer (Q) into a system and the work (W) done by the system.E2-E1=Q-W.Internal energy is the the energy possess by the system just like potential energy which possesed by the body on the height

U know the transcription very well which is the formation of mRNA from DNA.As DNA contains the coded information which is to be trancribed into mRNA,a protein called transcription factor binds to the DNA sequences and helps in the transfer of genetic information from the DNA to mRNA.

Enhancer is that reigon of DNA which binds to the trancription factor and causes the genetic information to be transcribed into mRNA.TATA box is the specific sequence which causes the RNA polymerase to recognize the initiation site.

The TATA box directs the RNA polymersase to the initiation site once the RNA polymerase has bound to the TATA box.

CATA box is the same as TATA box with same function but it is found in Human Immunodeficiency Virus Type 1.Its sequence is CATAAAA.

hello dear

for BITSAT u can refer the ncert BOOKS OF CHEMISTRY AND PHYSICS

CHEMISTRY NCERT INORGANIC CHEMITRY IS VERY GOOD FOR ALL THE COMPETATIVE EXAMS

PHYSICS NCERT THINKS TO REMEMBER ARE VERY USEFULL FOR ALL THE THEORITICAL TYPE OF QUESTIONS

hello dear

coaching at home for physics is outdated book but i suggest u to for the basic books like::

HC verma for problems ,its problem are very useful and it requires a clear cut concept

Resnik halliday refer for theory ,to get the grip over the concept

hey,

lysosomes are found in animal cell containing digestive enzymes

Lysosomes are used for the digestion of macromolecules from phagocytosis (ingestion of other dying cells or larger extracellular material, like foreign invading microbes), endocytosis (where receptor proteins are recycled from the cell surface), and autophagy (wherein old or unneeded organelles or proteins, or microbes that have invaded the cytoplasm are delivered to the lysosome). Autophagy may also lead to autophagic cell death, a form of programmed self-destruction, or autolysis, of the cell, which means that the cell is digesting itself.

hey dear,

there is no such news of there web site that when it is going to be it, so u ll have to wait for them to respond for 5th counseling...as they are busy in NIT agartala HS counseling right now.....

when is series combination::

v² / 3R = 10

when in parallel combination

 P = v² / (R/3)

now solve it

A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to mediate the union of male sperm with female ovum in order to produce seeds. The process begins with pollination, is followed by fertilization, leading to the formation and dispersal of the seeds. For the higher plants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across the landscape. The grouping of flowers on a plant are called the inflorescence.

In addition to serving as the reproductive organs of flowering plants, flowers have long been admired and used by humans, mainly to beautify their environment but also as a source of food.

hey morph in english means structure

term morphology in biology refers to form, structure and configuration of an organism.This includes aspects of the outward appearance (shape, structure, colour, pattern)as well as the form and structure of the internal parts like bones and organs. This is in contrast to physiology, which deals primarily with function.

Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. It can be subdivided into two distinct branches: anatomy is the study of the structure and internal organs of an organism. The study of the external appearance of an organism is called eidonomy, but while predominant early in the history of biology it is little studied in particular anymore as it is ripe with the effects of convergent evolution. It thus yields less new information about organisms than anatomy, and therefore the external appearance of lifeforms is usually studied as part of general investigations in morphology, e.g. in the context of phylogenetic research.
