Dual visual system:
Dual visual system is nothing but the different visual systems that our brain is meant to direct.
The two visual systems are
- Dorsal Stream
- Ventral Stream
Dorsal Stream:
Dorsal stream is mainly referred as a vision of action. This visual system is involved in moment by moment analysis. It is also known as where stream.
Ventral Stream:
Ventral stream is mainly referred to as the vision of perception. This visual system is meant to analyse and recognize shape and object etc. It is also known as What stream
Blindness:
Blindness is a defined as the lack of vision. Such type of vision loss can't be corrected either by contact lens or through glasses.
There are two type of blindness,
- Temporary Blindness
- Permanent Blindness
Temporary blindness is a condition where the vision of an individual vision is limited.
Permanent Blindness is a condition where an individual can't see anything even the light
The term used to describe the number of individuals moving into a population is Immigration.

Explanation:
The homeotic genes refer to evolutionarily conserved genes that modulate the development of different structures in organisms of the same groups (in this case, plants). Moreover, homeobox genes are genes that encode transcription factors involved in the regulation of development in eukaryotic organisms. The knotted1 (<em>kn1</em>) gene is a plant homeobox gene is a member of the <em>kn1</em> homeobox (<em>knox</em>) gene family, which is responsible for maintaining indeterminacy and preventing cellular differentiation. In maize, <em>kn1</em> plays a key role in maintaining the cells of the shoot apical meristem in an undifferentiated state, being mainly expressed in shoot meristems during postembryonic stages of shoot development. It has been observed that maize mutant plants where <em>kn1</em> is ectopically expressed (i.e., in tissues in which this gene is not normally expressed) exhibit proximal-distal patterning defects.
En las arqueas, generalmente se encuentra en la forma L-isomérica, mientras que las bacterias y eucariotas tienen la forma D-isomérica. Una segunda diferencia es la presencia de un enlace éter en oposición a los lípidos enlazados a éster que se encuentran en eubacterias y eucariotas.
Answer:
Given enough pressure,organic matter can also become natural gas. Heat and pressure are two main forces that transform organic matter into fossil fuels
