In each case, individual cell reactions are transmitted via inter cellular signals to neighbouring cells and integrated to generate a global cellular response at the level of tissues, organ and body. Water is the most abundant molecule in cells, accounting for 70% or more of total cell mass. The base pairs in DNA and RNA strands are connected by hydrogen bonds. Examples include calcium signal passing through gap junctions in cardiac muscle tissue to synchronize beating of cardiomyocytes and supracellular actin cables that synchronize cell movements in development. The steroid hormone receptors act by directly influencing gene expression. Insects eat plants, birds eat insects, bacteria and fungi in the soil decompose birds and other organisms when they die, and plants obtain vital nutrients from the soil. Plant cells are also responsible for acting as a source of energy for plants through photosynthesis. -Genetic diversity and adaptation. : Hibernating during winter, have thick coat of fur etc. -Gas exchange.

It is responsible for the production of gametes, which are the cells necessary for sexual reproduction, and for the fertilization and development of offspring. Tes Global Ltd is In this argument, human behavior is learned through the influence of society, aforementioned biological processes, as they are, of course, crucial to life. This can be shown by mutualism which is an interaction between two different species of living organisms in which both parties benefit. Since the Earths natural resources are limited, it necessary for species of all kingdoms to fight in order to gain enough nutrients in order to not only live but thrive and go on to produce future generations. There are many different types of interactions that can take place in which some organisms benefit and some are harmed.
