What is the relationship of nitrogen and grass
fredd [130]

Nitrogen is the major nutrient required by grass and is used to stimulate high growth rates and is key to achieving high yields, however if too much nitrogen is applied this can have a negative effects on quality.

High rates of nitrogen can also cause problems with silage fermentation due to excess nitrate having a negative impact on the fermentation process and will produce silage that is less palatable and the animals will be less keen to eat it.

<span> <span> </span> </span> <span> Nitrate is generally taken up by grasses quicker than it is incorporated into proteins and until used this excess known as luxury uptake is stored in the leaves. Excess nitrate will be present if insufficient time is allowed between application and mowing and can also occur under conditions of poor growth eg low light levels, cool temperatures. It is also a problem if there is a dry spell after application, when nitrate cannot be taken up by the roots, followed by a period of wet weather that results in luxury uptake. The plant cannot convert it to protein quickly enough so it accumulates in the plant. </span>

High rates of nitrogen may cause a reduction in crop sugars as they are used to provide energy for the increased rate of plant growth and for the manufacture of plant proteins and this increased growth rate may in turn lead to lower crop dry matter content although in practice this is often not significant.

Excess nitrate can be avoided by following the Grassland Rule to apply nitrogen at the rate of no more than 2.5 kg N/ha/day.

Which of the following are chemoreceptors? hair cells in the cochlea receptors in the aortic and carotid bodies baroreceptors in
Mrac [35]

Answer:

The receptors in the aortic and carotid bodies are chemoreceptors.

Explanation:

Chemoreceptors are specialized cells that are responsible for detecting and converting chemical signals into biological signals, to relay that information to the brain, where they will finally be interpreted. Among them we find the peripheral chemoreceptors, which are the aortic bodies, located along the wall of the aortic arch and innervated by the vagus nerve, and the carotid bodies, located in the neck. . Carotid bodies are stimulated by variations in the concentration of oxygen and carbon dioxide in the blood, as well as variations in blood pH. When the pH decreases the CO2 increases and the oxygen decreases, they activate the chemoreceptors to increase breathing.

Answer:

mitosis

Explanation:

Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created. The single zygote cell never grows or divides my mitosis. It can only divide by meiosis to produce haploid cells once more, which then produce the main adult body.
