Explanation

The unit of rock that represents all rocks formed during the same geological time scale is a Series. 

Geochronologic Units:

The units of time in the geological time scale are called geochronologic units (e.g., eon, era, period, epoch)

Explanation

Radio telemetry is commonly used to track amphibians

But can only be used on relatively large individuals.

Harmonic direction finding can be used to track smaller animals, but its effectiveness has not been fully evaluated.

Explanation

 Zoological/botanical garden is not included under in situ conservation.

Explanation

 Ineffective in Large Areas – Difficult to cover extensive regions accurately.

Explanation

 It hibernates throughout the winter in the northwestern Himalayas

Currently, it only exists in Asia, mainly confined in the Himalayas of India, Bhutan, Nepal, China, and Pakistan.

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

 The heartbeat is normally initiated by the sinoatrial (SA) node, a group of specialized cells in the right atrium, acting as the heart's natural pacemaker. 

Explanation

Goblet cells are specialized cells that produce and secrete mucus, a key component of the protective mucus layer lining the respiratory and gastrointestinal tracts. 

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. 

Lipid Derived:

Steroid hormones are lipids, meaning they are fat-soluble molecules. 

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.
