Which of the following is NOT one of the Nervous System Functions?. Single choice.
Neko [114]

Answer:

4. Absorb extra fluid between the cells

Explanation:

The nervous system (SN) is a complex system that acts to receive sensory information through nerves, transmit this information via the spinal cord and finally process it in the brain. The SN has three main roles: sensory input, processing and motor output. The SN can be divided into the central nervous system (composed of the brain and spinal cord), and the peripheral nervous system (composed of those nerves located outside the brain and spinal cord). Moreover, the extracellular fluid between the cells comprises four types of fluids: 1-intravascular fluid (blood), 2-interstitial fluid, 3--transcellular fluid and 4-cerebrospinal fluid. The excess of these fluids is absorbed by the capillaries of the lymphatic system.

MA_775_DIABLO [31]

Answer:

The correct answer is D participation in the study will contribute to a better understanding of factors that may contribute to dementia.

Explanation:

Alzheimer"s disease is one the of principle neurodegenerative disorder caused by the mutation of tau protein and also occurs due to the accumulation of mis folded proteins or prions proteins.

     The one of the most common form of dementia is alzheimer"s disease which severely affect the brain basically the thinking power of brain.

    As cynthia"s family has a history of early onset Alzheimer"s disease which has affected some of her family members.That"s why cynthia wants to participate in this study to point out the factors which are responsible for the occurrence of this disease in her family.

A group of cells is assayed for DNA content immediately following mitosis and is found to have an average of 4 picograms of DNA
damaskus [11]

Answer:

b: 8;8

Explanation:

Mitotic or meiotic cell division constitute the m phase of the cell cycle. At the end of the m phase, the new cells enter the interphase stage of the cell cycle. The interphase is further sub-divided into;

  • <em>the G_0 phase,</em>
  • <em>the G_1 phase,</em>
  • <em>the S phase; and</em>
  • <em>the G_2 phase</em>.

The G_0 phase is essentially a resting phase. Cells that do not need to divide except when necessary move into this phase after exiting the m phase.

Actively dividing cells enter the G_1 phase after exiting the m phase. Cell development and growth takes place. From there, the cells enter the S phase where DNA replication/synthesis takes place. The cells then enter the G_2 phase where proteins are synthesized in preparation for division or m phase.

At the S phase, the amount of DNA a cell carries is doubled but the chromosome number remains the same. For example, if a cell enters the S phase with 2 g of DNA containing 10 chromosomes, at the end of S phase, the amount of DNA would have come 4 g while the number of chromosomes will remain 10.

Hence, if the average amount of DNA in the assayed cells immediately after mitosis is 4 picograms, the amount would be 8 picograms at the end of S phase and will still remains 8 picograms at the end of G_2 phase.

The correct option is b.
