Answer:
The reagents needed are Br₂ and FeBr₃
Explanation:
In order to make 3-bromo-5-isopropyltoluene starting with m-isopropyltoluene we need to add Bromine (Br₂) and Iron(III) bromide (FeBr₃).
Please see attached picture for the resulting product, 3-bromo-5-isopropyltoluene.
B.) exposure to seasonal changes
C.) exposure to human activity
D.) exposure to moonlight
a. helium (He)
b. fluorine (F)
c. carbon (C)
d. nitrogen (N)
b. changes to pressure
c. changes to precipitation
d. all of the above
Which of the following is not released by trees into the atmosphere?
a. oxygen
b. water vapor
c. ozone
d. none of the above
1. Answer is d. all of the above.
Climate can be defined as the data collection of weather conditions of a long period of time in a certain area. The weather conditions that affect to the climate are temperature, precipitation, atmospheric pressure, wind and so on. Any changes in weather can change the global climate.
2. Answer is c. ozone.
Trees release oxygen and water vapor into the atmosphere but not ozone. The oxygen gas is released by trees as the by-product of photosynthesis. This is the natural way of production of oxygen gas. Water vapor can be released due to the transpiration of trees.
1. The correct answer is option D. all of the above.
Global climate change will bring changes in temperature such as heat waves, droughts, volcanic eruption, deforestation, extinction of species due to large shift in temperatures, changes in precipitation such as heavy snowfall, ocean acidification, and ozone depletion.
2. The correct answer is option C, ozone.
Ozone is not released by trees into the atmosphere. Plants have chlorophyll and in the presence of sunlight plants uses sunlight and carbon dioxide to form glucose and oxygen.
6CO₂ + 6H₂O -> C₆H₁₂O₆ + 6O₂
During transpiration plants exhale water vapor through the stomata, tiny pores that are found on the surface of the leaves.
Thus trees never release ozone into the atmosphere.
This is an example of negative mutation. Negative mutations produce a phenotype that acts antagonistically to the wild-type phenotype. On the other hand positive mutation produce a phenotype that acts synergistically to the wild-type phenotype.
The negative mutation will negatively affect the long term survival of the butterfly species as the mutation makes the new butterfly offsprings more visible to predators.
Carbon −4
Nitrogen +5
Oxygen −2
