The correct answer is option C

The formation of new layer of floor in the ocean is called seafloor spreading. It is a geological process which is caused due to the volcanic activity.

In this the new oceanic crust is formed due to the volcanic activity and the older rocks move away from the mid oceanic ridge.

The new layer formed lies in the middle of the ocean and the older rocks or floor moves aside.

This process occurs due to the divergent plates and the gap between them increases forming new oceanic ridge.

Answer:

A) A medicine that is personalized towards an individual's DNA.

B) These new technologies will be a benefit towards human health because they will be more effective and will not be as hazardous.

2) The sequencing of the human genome changed the way doctors are analyzing personal disease and risk because they are now able to diagnose the disease risk factors, provide better treatment for patients, determine which type of disease it is more accurately, how much of a dose of medicine the patient needs, and figure out genetic disorders.

3) He is worried that people might be moving too fast regarding these developments and wants them to proceed slowly and carefully so there is no room for error.

4) Some benefits would be protection from other certain diseases, I can fix any sort of genetic disorder, and order it so I can become stronger. However, I’m concerned that there will be risks in the sequencing process, which will change my genome for the worse.

5) Many potential biomarkers have yet to be verified and qualified for use, the FDA has yet to set a regulatory approval pathway for these products, the success of personalized medicine is contingent the ability of scientists and healthcare providers to capture, manage, store, and provide access to data and medical information, in order for personalized medicine to succeed, healthcare providers, patients, and insurers must learn how it works, and there are many privacy, confidentiality and fair-use concerns.

6 It could influence the use of these technologies because rather than focusing on helping people, they will only think about the money, leading them to do it carelessly and recklessly.

A) I think that using the information in a person's genome to treat disease is a good idea because it is much more effective in preventing disease and can fix any sort of genetic disorder much more easily.

B) I think this should be controlled. To address the potential for loss of genetic privacy, make it so that person gives their consent and you only take what is needed without having to look at the whole genome.

Match the following organs and organ systems. 1.digestive system brain 2.central nervous system tracheal system 3.respiratory sy

Amiraneli [1.4K]

The correct macthing of the organs with their organ systems is as follows.

1. Digestive system - intestines.

2. Central nervous system - brain.

3. Respiratory system - tracheal system.

4. Excretory system - bladder.

Digestive system is made up of the alimentary canal consisting of the digestive organs and the glands. Among the digestive organs, the intestines play a major role in the process of digestion. The small intestine is the site of complete digestion which is associated with the pancreas and liver. The large intestine is involved the absorption of water from the digested food and remaining waste material is stored and thrown out of the body during defecation.

The central nervous system is made up of the brain and the spinal cord. The brain makes the largest part and the functional of the central nervous system. It controls most of the activities of the body. It is made up of three parts called the cerebrum, cerebellum and medualla oblongata and is protected by the skull.

The respiratory system is divided into the upper respiratory tract consisting of the nasal cavity, pharynx and larynx, and the lower respiratory tract consisting of the trachea, bronchi, bronchioles and the alveoli. The trachea or the wind pipe is a cylindrical tube infront of the oesophagus, supported by 16-20 C-shaped hyaline cartilage. It serves as a passage for air to move in and out of the lungs.

The excretory system is made up of a pair of kidneys, a pair of ureters, an urinary bladder and an urethra. The urine produced by the kidney flows through the ureters and is collected in the urinary bladder. A spinchter (a ring of muscle) guards the opening of the bladder into the urethra and relaxes only at the time of urination under the impulse from the brain.
