Answer:
The correct answer is - by absorbing too much sodium and water into the cells in the respiratory system.
Explanation:
Cystic fibrosis or CF is a genetic disorder that is caused by the presence of two defective genes that leads to the production of thick and sticky mucus in an individual that affects the respiratory and digestive system by clogging mucus in it.
Due to defective genes, there is an abnormal electrolyte transport system develops in which cells of the respiratory system including the lungs absorb an excessive amount of salt (sodium) and water. It all caused by deletion of the three letters which means an amino acid from a gene that leads to the disruption of the protein that controls the production of the mucus and abnormal electrolyte transport.
Answer:
Answer is C. Damage to C3, C4 or C5.
Explanation:
C1 - C7 are used to represent the number of vertebrae found at the cervical region of the vertebrae canal or column. The vertebrae column comprises off various vertebrae that protect the spinal cord,which starts from the neck region to the tail region.
The C3, C4 and C5 are at the midsection of the cervical region of the spine , and they provide support for the neck and the head.
These vertebrae contain nerves which if affected will cause a serious pain. which can actually affect his breathing. Because, the spinal nerves around the spinal cord are linked to the brain.
Answer:
The correct answer is - all of the above.
Explanation:
Rheumatoid arthritis (RA) causes aggravation of the linning of the joints, particularly in the hands, knee, and fingers. Signs and side effects incorporate red, swollen, excruciating joints, and diminished flexibility and mobility. Articular cartilage is damaged and fibrous tissue invades
If left untreated, it can make extreme harm to the joints and serious complexities in the significant organs. In it, fibrous tissues ossify and bones fuse Rheumatoid joint inflammation is an immune system illness and osteoarthritis is brought about by impacts of maturing. The synovial membrane becomes inflamed and thickens, forming a mass.
The correct answer is - all of the above.
The correct option is (a) 2 → 4 → 1 → 3
A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.
<h3>
What is genetic variation in population?</h3>
- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
- Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
