Not exact matches

Gradually organic chemicals were synthesized and eventually self - replicating complex molecules evolved, enabling the evolution of living cells, leading to multi - cellular organisms, plants and animals.

To help make ideas about energy more concrete, for example, the new unit will use a variety of analogies from more familiar physical systems (e.g., combustion and charging a cellphone battery) to help students understand those same energy - releasing and energy - requiring chemical reactions and energy transfer when they occur in living organisms (e.g., cellular respiration, creating a charge across a membrane in mitochondria and nerve cells) where the reactions are more complex and difficult to observe.

The fields within biology are further divided based on the scale at which organisms are studied and the methods used to study them: biochemistry examines the fundamental chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues and organ systems of an organism; and ecology examines how various organisms interrelate.

Theories about the emergence of life suggest that increasingly complex carbon - based chemistry led to self - replicating molecules — and, eventually, the appearance of the first cellular life forms.

The living organism is often too complex to identify the specific causes of a particular cellular behavior.

Proteins are responsible for the vast majority of the cellular functions that shape life, but like guests at a crowded dinner party, they interact transiently and in complex networks, making it difficult to determine which specific interactions are most important.

Only from these results can the team deduce which conditions are crucial for the development of complex life and whether Earth is the ideal place for the necessary cellular processes.

The HFSP supports novel, innovative and interdisciplinary basic research focused on the complex mechanisms of living organisms; topics range from molecular and cellular approaches to systems and cognitive neuroscience and the interactions between organisms.

Current in vitro hematopoiesis models fail to demonstrate the cellular diversity and complex functions of living bone marrow; hence, most translational studies relevant to the hematologic system are conducted in live animals.

The IncuCyte ® Live - Cell Analysis System continuously analyzes cell function and provides insights into the complex and dynamic cellular processes of immunology.

Mitochondria are the engines that drive cellular life, but these complex machines are vulnerable to a wide range of breakdowns, and hundreds of their component parts remain a functional mystery.

Scientists can hunt for extraterrestrial cellular life forms, such as bacteria or more complex life, by looking for

Scientists can hunt for extraterrestrial cellular life forms, such as bacteria or more complex life, by looking for certain chemicals on a planet or in its atmosphere, but virions do not create by - products like methane or oxygen.

Therefore, key challenges for biology in the twenty - first century are the exploration of the structure and the dynamics of this complex inter - and intra - cellular web of interactions that contribute to the structure and function of a living cell.
