because without the heart , blood cant transport to our any of our body because heart is the one who pump the blood and without the heart there is no blood
We aren't humans without one. The heart pumps blood and this is needed for our oxygen to pass through. Without one, we cannot tell if the baby of an pregnant woman is breating or not. Without the heart, we will not be alive. Hope this answer helps.
the ability of organisms to produce different phenotypes under different environmental conditions (phenotypic plasticity) has been an object of evolutionary and ecological studies since the neodarwinian synthesis. yet, until lately, our knowledge in this field was limited to statistical approaches based on the classical tools of quantitative genetics. in recent years, however, a new dialog between organismal biologists and researchers interested in uncovering the mechanistic details of physiological and phenotypic responses has yielded several new insights. some classic examples of phenotypic plasticity have now been traced to specific alterations in dna transcription and rna translation rates, and to changes in patterns of protein expression. conversely, the explicit use of evolutionary and ecological theory is helping us to put a panoply of molecular data into a coherent historical and organismal perspective.

a kitchen utensil is a small hand held tool used for food preparation. common kitchen tasks include cutting food items to size, heating food on an open fire or on a stove, baking, grinding, mixing, blending, and measuring; different utensils are made for each task. a general purpose utensil such as a chef's knife may be used for a variety of foods; other kitchen utensils are highly specialized and may be used only in connection with preparation of a particular type of food, such as an egg separator or an apple corer. some specialized utensils are used when an operation is to be repeated many times, or when the cook has limited dexterity or mobility. the number of utensils in a household kitchen varies with time and the style of cooking.
