Broca's area

Explanation:

Broca area is the region of the brain that contains neurons involved in speech functioning. It is located in the frontal part of the left hemisphere of the brain,

the broca's area is known and considered to be responsible for controlling the muscles of related movements of lips, tongue, larynx, and pharynx.

Damage to the frontal area can result to speech disorder known as broca aphasia, which can be characterized by deliberate, telegraphic speech with very simple grammatical structure, though the speaker may be quite clear as to what he or she wishes to say and may communicate successfully.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
