Cancer Unit
Different types of cancers and where they originate
Melanoma= skin
Leukemia = white blood cell in bone marrow
Carcinoma= Lining of internal organ or skin
sarcoma= connective tissue
Lymphona= cells and tissue of the immune system
Difference between prokaryotes and eukaryotes
Prokaryotic Cells=Bacteria and Archaea,
DNA, but no nucleus (have a nucleoidregion).
Ribosomes synthesize proteins.
Plasma Membrane (barrier betweenoutside and inside)
Cytoplasm (fluid inside cell)
Cell...
1. Basic Concepts
Population: Entire group of interest
Sample: Subset of population
Parameter: Describes population (e.g., μ)
Statistic: Describes sample (e.g., x̄)
Descriptive Statistics: Organizing/summarizing data
Inferential Statistics: Drawing conclusions about population from sample
2. Data Types & Measurement Levels
Level Properties Examples
Nominal Categories only Gender, colors
Ordinal Ordered categories Ratings (good/fair/poor)
Interval Ordered, equal intervals, no tru zero Temperature...
Q.3 What are the differences between NameNode and DataNode?
NameNode is the master node in HDFS, while DataNode is the slave node.
NameNode stores metadata like file names, directory structure, permissions, etc.
DataNode stores the actual data blocks of the files.
NameNode manages the namespace and regulates access to files.
DataNode performs read and write operations on HDFS blocks.
There is only one active NameNode (with a standby for high availability).
There are usually many DataNodes
Stress: Circumstances that threaten or are perceived to threaten one’s well-being and tax coping abilities.
Common stressors: Frustration, conflict, change, pressure.
| Type | Description |
|---|---|
| Frustration | Occurs when pursuit of a goal is blocked. |
| Conflict | When two or more incompatible motivations compete. Examples: 🔹 Approach-Approach – two good choices. 🔹 Avoidance-Avoidance – two bad choices. 🔹 Approach-Avoidance – one choice |
The Spiral Model, proposed by Barry Boehm in 1986, is a software development process model that combines elements of both the Waterfall Model and Prototyping. It is mainly used for large, complex, and high-risk projects where requirements are not well understood from the beginning.
Each loop (iteration) of the spiral represents a phase in the software process and includes four major activities:
Planning:
Identify objectives,
EXP-6
#include <iostream>
#include <cstring>
using namespace std;
int z = 0, i = 0, j = 0, c = 0;
char a[16], ac[20], stk[15], act[10];
void check() {
strcpy(ac, "REDUCE TO E -> ");
for (z = 0; z < c; z++) {
if (stk[z] == '4') {
cout << ac << "4" << endl;
stk[z] = 'E';
stk[z + 1] = '\0';
cout << "$" << stk << "\t" << a << "$\t";
}
Chapter 13 covers bacterial genome replication and expression. Griffith’s transformation experiment demonstrated that non-virulent bacteria could become virulent by absorbing DNA from dead virulent cells, proving that DNA is the genetic material. The Hershey and Chase experiment used radioactive labeling (phosphorus for DNA and sulfur for protein) to confirm that only DNA enters bacterial cells during phage infection, further establishing DNA as the genetic material. DNA has a double-helix structure
