Marine biology is the scientific study of organisms in the ocean or other marine bodies of water. There are a few sub fields, including phycology, invertebrate zoology, and ichthyology.
The Microbes are known as organisms the 3 focal ones are
Bacteria - eg. salmonella, Diarrhoeal, shigellae and more they are common diseases u can find in bacterial water
Fungus - this causes athletes foot which is rather disgusting, it infects your feet, it can happen by sharing same towel with an infected person AND it makes moulds you see in expired food.
Virus - these microbes spread and they are like HIV/AIDS, they only infect living organisms the cells, rabies, influenza (the flu), cough but the difference is HIV can kill you
Nerve endings are broken down in the human body and not calculated (such as different organs, skin, etc.) Please go onto: www.google.com Ask your question.
Well, if the allele is recessive then it will only be expressed if there is no dominant allele present. Like blue eyes. We will say that B is the dominant brown eye gene and b is the recessive blue eye gene. For almost all chromosomes in you cells (all if you are female) there will be a pair. So, you will have two copies of the gene, in this case eye color. You will get one from your mother and one from your father. If you got the brown eyes from your mother but blue from your father you would have this pair Bb, B will always show up so your eyes will be brown. If both of your parents gave you a gene for blue eyes you would have this pair, bb. There is no brown eye gene to express so you eyes will be blue. On to your question. In males the sex chromosomes are not a matched pair. You will inherit the full chromosome, called X, from your mother and a partial chromosome, called Y from your father. The Y does not carry very many genes and so any genes on your X will be expressed even if they are recessive. Take the gene for hemophilia, we will call it h. If your father is not a hemophiliac then his single X will be H, the healthy dominant gene. Your mother in this case is a carrier. She has two X chromosomes, Hh, but the H is dominant so she is not a hemophiliac either. Your sister could either be HH or Hh, she will always get an H from your father's X. She will either be healthy or a carrier but never a hemophiliac. Your brother on the other hand is in some danger. He will not inherit your father's healthy X chromosome. He will get your father's Y. So, the only X he will get will come from your mother. He has a 50% chance of getting the H and a 50% chance of getting the h. If he gets the h from your mother that will be his only H/h gene because he only has one X chromosome. He will be a hemophiliac. Gene-linked conditions carried on the X chromosome, like hemophila or color-blindness, are called sex-linked because they are linked to the chromosomes that determine sex. The only way a girl could be a hemophiliac would be if her father was one and her mother was a carrier. She would then have a 50% chance to inherit her mother's h gene and she would have a 100% chance to inherit her father's h gene. But, the parents would know the father was a hemophiliac and would most likely either adopt or have the mother tested to see if she carried the gene before trying for a baby. In essence, women have a back-up parachute on their other X. Men don't have another X so they don't have a back-up. Hope this helps!
To take a pulse, hold the wrist with only your two fingers pressed gently on the inside of the wrist. Palpate gently until you feel the pulse pulsating, and then count the number of pulse you feel for one minute. You can also do this by pressing your two fingers just under the chin bone on either side of the neck.
Here is a general standard of pulse rate (PR). Resting Pulse Rate PR < 40 BMP - Below healthy resting heart rates. PR 40-60 BPM - Resting heart rate for sleeping. PR 60-100 BPM - Healthy adult resting heart rate. PR 100 BPM - 220 BPM - Acceptable if measured during exercise. Not acceptable if resting heart rate. PR > 220 BPM - Abnormally high heart rate.
