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
The first one, is :
Embryology - The branch of biology and medicine concerned with the study of embryos and their development.
The second one is:
Vestial Traits - An anatomical feature or behavior that no longer seems to have a purpose in the current form of an organism of the given species.
You can work out the concentration of H+ ions (denoted as [H+]) easily on a calculator if you know the pH, which you do. The easiest way to work out [H+] is to do
. In your case, the maths here would be
, which gets you an answer of 1.58x
, or 0.000158. For 6.2 it would be
, which gives you 6.31x
, or 0.00000063. As you can see, the concentration of H+ ions is greater in pH 3.8.
To put it simply, the [H+] decreases the higher up the pH scale you go, and increases as you go lower, but now you know the maths to work it out for yourself too.
1.GMO's have both pros and cons.
Pros like 1) GM crops have more nutrients, are resistant to pesticides and grow quickly. 2) Artificially bringing change by manipulating the DNA will save many years of research as observed with traditional breeding methods.
Cons like 1) Some cases of health risk like liver and kidney problem has been observed with the use of GM crops. GMOs can also affect those with allergies. Enough research is not done on health effects. 2) Higher levels of toxins could be produced with the insertion of a foreign plant gene.
2. According to my opinion, GMOs should be used to solve human problems but it should be brought after proper research being done. The most important role of GM crops is to ensure that there is enough to eat. Since the global population is expected to reach more than nine billion by 2050, there will be increasing demand for food. Although agricultural productivity has improved drastically, production might not be sufficient to meet demand unless we start using significantly more land, fertilizer, and water. Further the change in climate will make the situation worse. So under such conditions if we can use GM crops which are more tolerant to such harsh conditions and use less fertilizers then it's a boon definitely.
