What subatomic particle’s number uniquely defines an element and is its atomic number?
💡 Explanation:The atomic number (Z) of an element is defined by the number of protons in the nucleus. Changing the number of protons changes the element itself. The number of neutrons can change to form an isotope, and the number of electrons can change to form an ion, neither of which changes the fundamental identity (element) of the atom.

💡 Explanation:Modern data-driven safety policies for sports fields prioritize the objective biophysical properties, such as traction and firmness, tested by devices. This approach is adopted because medical studies often show no statistically significant differences in injury rates solely attributable to the general surface type (e.g., grass versus synthetic).

When downloading a large file, which protocol primarily ensures that data packets arrive in the correct sequence and are acknowledged?
💡 Explanation:Transmission Control Protocol (TCP) is a core transport layer protocol responsible for reliable, ordered, and error-checked delivery of data streams. It establishes a connection, segments data, retransmits lost packets, and ensures data arrives in the correct sequence (acknowledged). User Datagram Protocol (UDP) is also transport layer but is connectionless and unreliable, prioritizing speed over guaranteed delivery. IP handles addressing and routing, while HTTP is an application layer protocol that typically uses TCP.
