Explanation:
Yes, Sammy is alive. Losing his hand and getting an artificial one doesn't change his life status. Vital organs and biological processes determine life, not limb loss.
Yes, Sammy is alive. The incident of losing his hand and replacing it with an artificial hand does not necessarily mean he is no longer alive. The loss of a body part does not define one's life status. Being alive is determined by the functioning of vital organs and biological processes, which are not affected by the loss of a single limb.
Despite the accident, Sammy's heart is still beating, he can breathe, and his brain is functioning. The artificial hand enhances his quality of life and functionality, but it does not alter his life status. As long as his essential biological functions persist, he remains alive.

Answer:
Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.
Explanation:
Enzymes affect activation energy by significantly lowering it. This reduction in activation energy increases the rate at which chemical reactions occur within cells. As a result, reactions that might occur too slowly or not at all because of high activation energies proceed rapidly in the presence of enzymes, facilitating the complex network of metabolic pathways necessary for life.
Activation energy is the minimum amount of energy required for reactants to transform into products in a chemical reaction. In biochemical processes, this energy barrier can prevent vital reactions from happening at efficient rates. Enzymes serve as biological catalysts that lower this barrier, making it easier for the reaction to occur without the need for excessive heat which is unattainable in living cells. These catalysts work by binding to reactant molecules, stabilizing the transition state, and thereby decreasing the necessary energy for the reaction. For instance, in cellular respiration, glucose is a key reactant transformed into energy. The production of glucose is through photosynthesis, which is an endothermic reaction because it requires energy input from sunlight. Proper nutrition and regular exercise are crucial for maintaining a healthy body as they ensure the availability of necessary substrates and optimized enzyme function for metabolic reactions.

LO 5-3 How does the nervous
system communicate electrica
and chemical messages from
one part to another?
Final answer:
The nervous system communicates through an electrochemical process, where electrical signals within neurons are combined with chemical signals via neurotransmitters across synapses, enabling efficient transmission of messages throughout the body.
Explanation:
How the Nervous System Communicates
The nervous system uses an intricate electrochemical process to communicate messages across different parts of the body. This complex process involves both electrical signals within neurons and chemical messengers known as neurotransmitters to transmit information between neurons. Let's break this process down into understandable parts:
Electrical Signaling: Within a neuron, an electrical signal travels from the dendrites, through the cell body (soma), and along the axon to the nerve terminal.Chemical Signaling: Once the electrical signal reaches the axon's end, it triggers the release of neurotransmitters into the synapse, the gap between neurons. These chemical messengers then bind to receptor sites on the adjacent neuron, effectively transmitting the signal across the gap.This combination of electrical and chemical signaling allows for fast and efficient communication throughout the nervous system, enabling response to stimuli and coordination of activities.Through this powerful electrochemical mechanism, our nervous system controls everything from simple reflexes to complex thoughts and emotions.
