V125BC [204]

Answer:

1) Skull and Vertebral column

2) Meninges

3) Cerebrospinal fluid.

Explanation:

Central Nervous system:

CNS is the abbreviation of Central Nervous system. CNS controls the whole body functions so it is the most important component of the body. CNS consist of two parts 1) Brain and 2) Spinal cord

Both of these organs are very important and hence need to be protected. Nature provided these organs with certain protective mechanisms these includes

1) Skull and Vertebral column:

Skull is present around brain and vertebral column is present around spinal cord. These structure provides mechanical support to soft parts of CNS.

2) Meninges:

These are the membranes that provide antiseptic environment to the brain and hence protect it from microbes and other harmful substances.

3) Cerebrospinal fluid:

This fluid is present inside meninges which nourishes the brain and protect it from mechanical stresses.

Bad White [126]

Answer:

Use the CAM pathway

Explanation:

  • Xerophytes are plants  that have adapted to arid climates. They have evolutionary developed adaptations to reduce the rate of transpiration so as to conserve water.
  • Among the adaptations include; thick cuticle, small, thick leaves, reducing the surface area relative to the volume of the leaf, etc.
  • Additionally, they use CAM pathway as an alternative photosynthetic pathway to minimize water loss.

The sporophyte of an unknown plant species grows as a separate plant than the gametophyte. The plant produces both female and fl
N76 [4]

Answer:

The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".

Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.

They show alternation of generation in which sporophyte is the dominant stage.

The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.

The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.

The gametes fertilize to produce a diploid zygote.

The zygote divides mitotically and matures into the diploid sporophyte.
