Answer:
150.
Explanation:
150 flies are expected to have normal body color and to be eyeless in F2 generation. The reason for that population is the ratio of the species produced. The ratio of the species are 9:3:3:1. Ratio 9 refers to first parent while 1 refers to second parent and the middle 3's represent the hybrid formed. So the population of first parent is 450 and population of second parent is 50 while the population of two hybrids are 150 each.
The plants remaining would be the only plants then will come as the animals die because they cant eat plants because all the plants are gone then will come us which we will die because there aren't any animals to thrive on
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.
If they are trying to convert any measurements or just measure out the chemicals, it wouldn't be very familiar to them so they could make a mistake that can result of too much or too little of the chemicals, which can make the chemicals react differently.
