Answer:
C
Explanation:
The meninges are the membranous tissues that cover the spinal cord and the brain, providing support and protection to these organs. They are of three layers.
A) The Dura mater
B) The arachnoid mater
C) The pia mater
The Dura is the outermost meningeal layer and lies directly under the vertebral column bones and skull. The subdural space is the space between the Dura mater and the Arachnoid mater.
The Arachnoid mater lies in the middle of the Dura and Pia mater. Under the Arachnoid layer is the subarachnoid space which contains the cerebrospinal fluid. The cerebrospinal fluid acts as a shock absorber and a cushion to the brain and spinal cord.
The Pia mater lies under the subarachnoid space and directly on the spinal cord and brain and is highly vascularised.
Transcription starts at the template strand of DNA where mRNA attaches and is constructed from 5’ to 3’ direction. The nucleotides of the DNA strand is attached to either A, U, G, C ribosomal nucleotides. mRNA Dissembles when it reaches a terminating codon and then it attaches to ribosomal RNA where tRNA carries the amino and mRNA caries the code to construct proteins with the ribosome.
The species likely living in an ecosystem on the other side of the mountain farthest from the coast is the cactus.
- Cacti are evergreen plants. Their stems might be meaty or succulent, cylindrical or flattened.
- The stems are green in colour and photosynthetic, usually fulfilling this job instead of leaves, which are scarce or nonexistent in most adult cacti.
Most cactus species are well-defended by spiky bristles and spines that repel most animals.
- Cacti are xerophytic plants, which means they are physiologically and morphologically suited to the high water shortages of dry ecosystems like deserts.
- Cacti's xerophytic adaptations include (1) succulent, water-retaining stems, (2) a thick, waxy cuticle, and few or no leaves to decrease water losses through transpiration.

The given statement is False
Bleach such as chlorine when mixed in fertilizers acts as a killing agent for plants .The bleach runoff is not affected by the fertilizers containing bleach as they do not kill the Aquatic flora. Marine bleaching is caused due to high temperature of water not because of the fertilizers. In marine bleaching the coral will expel algae when the temperature of water is high. These results in discoloration of corals making them white and they can survive in this condition. This proves that the bleaching inside the marine system is because of high temperature not because of runoff.
