Genes and Genomes
Every cell contains a complete set of genetic instructions—the genome—encoded in DNA and organized into genes packaged on chromosomes. A gene is a specific DNA sequence that encodes a functional product (usually a protein or an RNA). Genetic variation (mutations) underlies phenotypic differences, while environmental factors also contribute to traits .

Handoff Strategies in Cellular Networks
Handoff strategies are essential in cellular networks to maintain call quality when a mobile device moves from one cell to another. The Mobile Switching Center (MSC) facilitates the seamless transfer of calls, ensuring minimal disruption to users.
1. Handoff Prioritization:
Handoffs are given priority over new call requests. This is crucial for maintaining ongoing conversations without interruption.
Ensuring successful and infrequent handoffs is important
Kcat = Vmax/ (Et)...... V0 = Vmax [S] / (ɑKM + [S])........
KI - dissociation constant for the inhibitor from the enzyme
Competetive Inhibiters: Affects the slope of the line, Y intercept (1/ Vmax) does not change, Km does Change (when A is high slope gets steeper and line moves closer to origin)
UnCompetetive Inhibiters: Apparent Km changes and Vmax changes (Parellel)
Mix: A is bigger and more competitive. a is less the uncompeteive. a is equal then non competeive.

1. Differentiate executeQuery() and executeUpdate() with example:
The method executeQuery() is used when you want to retrieve data from the database, typically using a SELECT statement. It returns a ResultSet object which contains the data returned by the query.
Example:
ResultSet rs = statement.executeQuery
("SELECT * FROM users");
while (rs.next()) {
System.out.println(rs.getString("username"));
}
The method executeUpdate(
Question Bank Topic 1 with Solutions – Net Value Functions Question Bank #1 – Net Value Functions: L03 – Engineering Economics & Net Value Applications Review Questions Recall the nanoRIMS example discussed in lecture. If the net value of buying the nanoparticles is $0 (the reference), determine the net value per week of having a grad student make the nanoparticles based on the following information: Benefit = $896/week Cost = Cost of consumable supplies per week Ingredients
...1. Functions of I/O Interface and Its Need
Functions of I/O Interface:
Synchronizes the speed difference between CPU and I/O devices.
Selects and addresses the appropriate I/O device for communication.
Provides control and timing signals for data transfer.
Buffers data during transfer, managing data flow between CPU and devices.
Converts data formats (e.g., serial to parallel, digital to analog and vice versa).
Detects and reports errors during data transfer.
Handles interrupts to inform CPU when

Software Engineering is called a layered technology because it is built on a foundation with multiple layers, each supporting the one above it. The layers are:

1. Shape Memory Alloys (SMAs)
Definition
Shape Memory Alloys R metallic materials that can recover their original shape after deformation when exposed 2 a specific stimulus, usually heat.
The most common example is Nickel-Titanium (Nitinol), known 4 its shape memory & superelastic behavior.
Mechanism
a. Phase Transformation
SMAs operate through a solid-state transformation between 2 phases:
