Answer:

<u>The soil losses its fertility when we grow many crops again and again on it as the consume all the nutrients present there. it can be restored by growing legumes in the soil or leave it barren for some </u><u>months</u>

Soil loses its fertility or when topsoil is lost due to erosion. ... The cotton took all the nutrients from the soil, and the nutrients were not replaced. Loss of Topsoil: Wherever soil is exposed, wind and water can erode it. Plants can cover and protect the soil in many ways.

Neutrophils They kill and then digest the bacteria and the fungi. They are the most numerous type of the white blood cell and your first line of the defense when the infection strikes.

A high level of neutrophils in the blood is called neutrophilia. This is a sign that your body is infected. Neutrophilia can indicate many underlying conditions and factors, including: Infection, possibly bacteria. They capture and destroy invading microbes through phagocytosis and intracellular degradation, release of granules, and formation of neutrophil extracellular traps upon detection of pathogens. Neutrophils are also involved as inflammatory mediators. What is the most common cause of high neutrophils? infection. This is the most common cause of high neutrophil counts. Most bacterial infections cause elevated neutrophil counts, but not all. Viral infections generally do not cause neutrophilia, but it can occur early in the infection.

A detailed comparison between all of the above details of photosynthesis to the process or subject of your choice

A detailed comparison between all of the above details of photosynthesis to the process or subject of your choice?For example if we are going to do cake we are going to need to get all the ingredients so we could start baking when we start mixing the ingredients the cake is almost ready to be baked. We then put it to a pan and put it in the oven to start to bake, And then we have cake. This is like the process of photosynthesis because photosynthesis takes in sun light and then converts oxygen to glucose. The Cake takes in its ingredients and then it gets bake and it gives us energy

A forest has two groups of plants that appear to be very similar both phenotypically and genotypically. The major difference is
Andru [333]
<span>In order to know whether the plants are members of one population with great diversity or actually members of the same species we can attempt to find out whether they reproduce or not. That's one of the main aspects of two organisms of the same species - fertility.

We could start by setting up some kind of artificial environment where both plants would pollenise at the same time, or we could also collect the pollens from both plants and store it to use them in a different time of the year than that of their production. 

After having the pollens available from both plants we could fertilise a group of both plants with each other's pollens (the actual object of study), and also fertilise a group of both plants with their own pollens (so we can have a control for the quality of the pollens and the plants - in this group it is expected to have offspring, if there isn't we cannot take into account any other results).

After the fertilisation, we should now count the offspring. If there is offspring resulting from the crossed plants, they are probably of the same species. We could also compare these plants with the offspring of the normal crossing to check whether there were major differences (such as health issues, or offspring number) that would lead to conclude that still there wasn't compatibility. 

By creating a hybrid between this two groups, even if they are from the same species, we may have to take also into account that they may have different required conditions than their parent plants.

</span>The study should be repeated a few times or the number of plants involved should be large enough to be statistically relevant.
