Explanation

 MOT is widely used in autonomous vehicles, surveillance, sports analytics, and biological studies (e.g., tracking animal movement).

Key Aspects of MOT:

Detection – Identifying multiple objects in each frame.

Association – Matching detected objects across frames to maintain consistent tracking.

Prediction – Estimating object positions in future frames (e.g., using Kalman filters).

Data Fusion – Combining information from multiple sources (e.g., LiDAR, cameras) for more accurate tracking.

Explanation

 Human sex hormones, also known as sex steroids, are made up of steroids specifically derived from cholesterol. 

Steroid Hormones:

Sex hormones, like testosterone, estrogen, and progesterone, belong to a class of hormones called steroid hormones.

Cholesterol as Precursor:

These hormones are synthesized from cholesterol, a type of lipid. 

Explanation

The enzyme responsible for joining Okazaki fragments during DNA replication is DNA ligase. 

Explanation

Let the circumference of the circle = perimeter of the square = P  

- Circumference of circle = 2πr  

- Perimeter of square = 4a (a = side of square)  

So, 2πr = 4a ⇒ a = (πr)/2

- Area of circle = πr²  

- Area of square = a² = (πr/2)² = (π²r²)/4

Now compare:

πr² (circle) vs. (π²r²)/4 (square)  

Divide both sides:  

(πr²) / ((π²r²)/4) = 4/π > 1 ⇒ area of circle > area of square.

Explanation

 The sensitivity of blood tissue to radiation primarily depends on the mitotic rate of cells.

Cells that divide rapidly, such as blood-forming cells in the bone marrow, are more vulnerable to radiation damage.

This is because radiation mainly affects DNA replication and cell division, making highly mitotic cells more susceptible to its effects
