He first divided all living organisms in 2 groups
Animal or Plant
He then put these into subgroups
Animal subgroups: land, water, air
Plant subgroups, small medium or large
Not a very specific approach to taxonomy but it was used for well over 100 years
The answer bnb is true becuase without desity in anything nothing would circulate
The Type O blood group is commonly called as universal donor because any blood group can receive the O blood group. The blood group O has no antigen. Due to the absence of antigen it doesn't agglutinate when come in contact with other blood groups in the plasma.
The agglutination reaction happens when opposite antigen and antibody reacts with each other. e.g.- Blood group A contains antigen A and antibody b and the blood group B contains antigen B and antibody a. Agglutination reaction occurs when the antigen A reacts with antibody a. As O blood group has no antigen, agglutination reaction doesn't occur.
The hereditary form of hypertension is detected when the adrenal gland produces too much aldosterone.
<u>Explanation:</u>
Hypertension is an important risk factor for several cardiovascular disease. If prolonged it damages the blood vessels causing malfunctioning of the heart, kidneys and brain. Hypertension can be caused due to various genetic or environmental factors.
There are cases where familial hypertension are detected. This is caused due to the mutation in a single gene which is passed on to the generations where even in young age the children are seen affected with hypertension.
This in medical terms is termed as familial hyperaldosteronism type II. This is occurred due to the mutation in CLCN2 gene. It tends to produce too much of aldosterone hormone which causes high blood pressure.
Fluorescent in situ hybridization (Fish) is a method employing a fluorescent dye covalently bonded to a specific nucleic acid probe identifying or tracking organisms in the environment. Fluorescent in situ hybridization (fish) can be used to determine; how many salmonella typhimurium cells are present in a sample of unpasteurized apple juice, the phylogenetic diversity of an environmental sample and also whether a specific piece of mRNA is being produced.
