Answer:
Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.
Explanation:
Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.
Answer:
Nature and Nurture
Explanation:
Dr Bartholomew believes that behaviour is because of nurture, meaning that it is based on where you are raised or who raised you.
Dr. Tiburon on te other hand believe that behaiour is something that you inherit from birth and therefore believes in nature.
Answer:
Mitochondria The eukaryotic cell structure where cellular respiration occurs because they are are organelles whose membranes are specialized for aerobic respiration.
In today's society, the theory of Darwin - the theory of evolution, which states that all organisms have evolved from simple organisms to more and more complex organisms all the way to us, is favoured and viewed as something that seems to be true, at least when considering all the available evidence.
All deuterostomes are triploblastic and have three tissue layers.
