Answer:
The correct answer is - The axis must be tilted at a certain angle that." remains unchanged.
Explanation:
On the earth there ae many seasons but there are four major season, winter, summer, spring and autumn. The main reason that leads to all four season is the tilt of the sun at a specific angle that remain unchanged which leads to change in the distance to the sun at specific time of the year which result in different rays of sun the part. So, whatever hemisphere or part tilted towards the sun leads to different season for instance:
North pole tilted towards the sun - summer in northern hemisphere
south pole tilted towards the sun - winter in northern hemisphere
Answer:
Option A, Offshore Drilling
Explanation:
In the process of offshore drilling, oil is extracted from the wells which are located at the surface of ocean floor.
Different types of oil rigs are used for oil extraction depending on the depth of the ocean.
It is a good mode of extracting oil from sources that have remained untapped since long. With the new technology, several nations have been able to explore this oil reserve and have become independent in terms of energy
Hence, option A is correct
Apply a water-soluble lubricant to the nares.
Nares is simply the medical term for nostrils and the irritation is likely due to the NG tube rubbing the interior of the nares. Applying a lubricant will reduce the irritating friction. re-positioning either the NG tube or the client might cause temporary relief, but would most likely cause another part of the nares to become irritated, compounding the problem. The lubrication deals with the root cause of the irritation.
The following are the disadvantages of sexual reproduction:
1. Sexual reproduction requires a male and female partner, without the two coming together reproduction can not take place. Getting a partner might be difficult if there is disparity between the number of males and females in the area.
2. Sexual reproduction takes time and energy. The process is labour intensive and time consuming. For example, the male animal needs to court the female animal and build emotional connection before copulation can occur. Not all copulations are successful at the first attempt, some animals may have to copulate several time before fertilization occur.
3. Sexual reproduction reproduce fewer offspring than asexual reproduction.
4. Sexual reproduction can prevent favourable genes from being passed to the offspring.
