Explanation

Trees as Environmental Buffers:

Climate Regulation: Absorb CO₂, release O₂, and moderate temperatures.

Soil Protection: Prevent erosion and maintain soil health.

Water Cycle: Help in groundwater recharge and reduce flooding.

Explanation

A refrigerator transfers heat from inside to outside using thermodynamic cycles.

It relies on principles like heat absorption, compression, and expansion of refrigerants.

Explanation

• An acid is a substance that donates a proton (H+ ion) in a reaction, increasing the concentration of hydrogen ions in an aqueous solution.
• Examples of acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and acetic acid (CH3COOH).

Explanation

The approximate height of Earth's atmosphere is 6,200 miles (10,000 kilometers).

This is the approximate extent of the exosphere, the outermost layer of the atmosphere, which gradually merges with space. 

Explanation

The Sun has already used up roughly half of its hydrogen fuel in approximately 4.6 billion years.

It is currently in the stable phase of its life cycle, converting hydrogen to helium through nuclear fusion.

In about 5 billion years, the Sun will exhaust its hydrogen fuel and begin its transformation into a red giant.

Explanation

 Morphology:

This field studies the structure of words, including their parts of speech, prefixes, suffixes, and how they are formed.

Syntax:

This field examines how words are put together to form sentences

Etymology:

This field investigates the origin and historical development of words

Explanation

Potential energy and kinetic energy are types of mechanical energy. 

Mechanical energy encompasses both potential energy (stored energy due to position) and kinetic energy (energy of motion). 

Explanation

Soil erosion is primarily caused by the natural forces of water and wind, as well as human activities that disrupt the soil.

These factors can accelerate the process of topsoil removal, leading to land degradation and decreased fertility. 

Explanation

 Non-invasive Genetic Sampling:

This method involves collecting genetic material (like DNA) from animals without direct contact, for example, through scat, hair, or shed skin.

Applications:

Species Identification: Identifying species based on genetic markers.

Individual Identification: Distinguishing between individuals within a population.

Population Size Estimation: Estimating the size of a population using genetic data.

Genetic Diversity Analysis: Assessing the genetic diversity and structure of populations.

Explanation

 Urial males have large horns, curling outwards from the top of the head turning in to end somewhere behind the head; females have shorter, compressed horns.

The horns of the males are up to 100 cm (39 in) long.

The shoulder height of an adult male urial is between 80 and 90 cm (31 and 35 in).
