The correct structure is shown below,
According to rules the longest carbon chain is selected, and numbering is started from side nearer to carbonyl group. As the parent name goes to ketone, so among alkyne and halogen second priority is given to alkyne and 3rd to halogen
So, the name shoul carry following words,
3- one (for ketone)
5-yne (for Alkyne)
7-Bromo (for Halogen)
Result: So the structure is as follow,
Answer:
A. Blood would leak backwards through the damaged valves due to gravity, causing lower leg swelling.
Explanation:
The passage of blood is always in a single direction in the vein due to the presence of valves in the veins.
Any kind of vein injury or vein rupture, causes the valves in the veins to not function in an appropriate manner. The injury might result in inappropriate opening and closing of these valves. The inappropriate functioning of the valves causes the blood to flow backwards. This will eventually lead to blood pooling and putting more pressure on the lower leg veins. hence, there would be swelling in the lower legs.
B. 245 million
from the end of Carboniferous Period to the beginning of the Triassic period
Answer:
its D
Explanation:
Its D cause plants use their roots to get water and the vascualar tissues are found in the root most of the time.
Answer:
Climate models can show the composition of the atmosphere in the future.
Explanation:
Climate models help predict how the average conditions will change in a region and they also serve as an extension of weather forecasting. They are quite broad and can make analysis and predictions over long time spans.
These models are generated from some set of mathematical principles with different data points numbering over a thousand. These large data points help increase the accuracy of the models.
