The human body has living cells that interact with other living cells (Food) and inorganic cells (Salt, Oxygen). It also has a lot of chemical reactions that simultaniously happen inside of it.
Inorganic systems usually do not interact with themselves, and the reactions are mostly exterior.
Answer:
The water bottle sign or configuration refers to the shape of the cardiac silhouette on erect frontal chest x-rays in patients who have a very large pericardial effusion. Typically the effusion has accumulated over many weeks to months (e.g. in patients with malignancy) and the pericardium has gradually stretched.
The answer should be allele(s).
Alleles are alternative forms of genes. For example in eye color, there is brown eye allele that produces brown eyes or blue eye alleles that produces blue eyes.
However, note that there may be dominant or recessive alleles. Dominant alleles are always expressed, meanwhile, recessive allele is only expressed when there is no dominant allele existing.
An example is let say brown eye allele is dominant and blue eye allele is recessive. The eye gene is controlled by 2 alleles. If I had one brown eye allele and 1 blue, my eyes will be brown, because brown eye allele is dominant.
Their location, or layer
The cells produce three germ layers:
endoderm- becomes the gut
mesoderm- becomes muscle, skeletal system, some organs, and connective tissure
ectoderm- becomes skin and nervous system
Answer: Blood is slightly more viscous then water, pH is slightly alkaline it is about 8% of ones body total body weight the rest of the options are slightly wrong.
Explanation: Blood is red in colour, a dark red when it is deoxygnated and bright red when oxygenated. Its normal pH is 7,4 making it slightly alkaline and it accounts for 8% of one's total body weight with 92% being water. Its temperatures ranges around our normal body temperature which is 37°C.
