true? i dont understand what you are asking?......
Answer: Symptoms of potassium deficiency appear on the lower portion of the plant first with chlorosis (yellowing) at the leaf margins followed by necrosis (death). Potassium deficiency can be caused by soil pH, extreme liming or calcium rich areas of fields, lack of soil oxygen or true soil deficiency.
If you talk about the process of fission in the nuclear field then the most used is U-235 because is the easiest to use. Have in mind that the majority of uses of uranium is U-238 but the easiest to be used is U-235
Answer:
Relative dating is the technique to calculate the age of an ancient materials in comparison to another material's age. Layer A is less older, if layer B lies beneath it. Layer A may be 2.5 to 3 million years old.
Explanation:
Before discovery of radioactive carbon dating method, geologists make use of relative dating method in order to determine the age of rock or fossils. The relative dating procedure often referred to as stratigraphy. Though this procedure is not capable of predict absolute age or dating. In relative dating, is mainly based on the fact that the older rock layers will be deeper in respect to the less older rock layer.
Answer:
Biochemistry is integrated into the Health science field.
Explanation:
For Health Science, you are dealing with the human body. To solve issues in the human body, you need to understand how it works. This would include both biology and chemistry. Biochemistry just so happens to be a combination of both,and is sometimes called biological chemistry. It is the study of chemical processes within and relating to living organisms, and is usually taken by students who aren't taking Organic Chemistry. Health science has a lot of work in helping athletes train and get back into the game after injuries. If you go along with this example, then you'll understand where biochemistry comes into play. In order to help the athlete heal, you have to be able to understand how your muscles, bones, or even immune system work on a microscopic level. Chemistry comes into play if you have to consider how medications they might be taking may be affecting them, or how their hormones are coming into play.
