Answer:
c. It is a systemic inflammatory disease.
Explanation:
One of the main characteristics of rheumatoid arthritis is that is a systemic inflammatory disease. This disease can affect the entire body and is not just localized to the individual's joints. In many cases the disease has been known to attack an individual's skin, eyes, lings, heart and even the blood vessels within the individual's system.
Answer:
It can cause air and groundwater pollution.
Explanation:
All other answers are benefits. Renewable and abundant sources won't run out for a <em>long </em>time, if ever. Reducing greenhouse emissions is good for the environment.
Answer:
A) proteins in the cell will include lysine instead of phenylalanine at amino acid positions specified by the codon UUU.
Explanation:
Anticodon is the name given to each set of nucleotides complementary to the triads of nucleotides found in mRNA. As you may already know, each nucleotide is formed by a nitrogenous base; in the case of RNA, the nitrogenous bases are adenine (A), uracilla (U), guanine (G) and cytosine (C), each nitrogenous base binds with its complementary nitrogen base. For this reason, a codon formed by the UUU crack will have as its anticodon a crack formed by AAA.
Based on this, we can conclude that in a mutant bacteria that binds lysine to tRNAs with the AAA anticodon instead of normal phenylalanine, proteins in the cell will include lysine instead of phenylalanine at the amino acid positions specified by the UUU codon.
Answer:
The majority of marine organisms are found in coastal regions.
Explanation:
The majority of marine organisms are found in coastal regions because ocean flows bring nutrient-rich water into coastal areas. Marine coasts are the type of environments that change through the weathering process and change in sea levels. Coastlines mostly consist of continental shelves that contain relatively shallow waters of having 200-meter depths only.
Since water is shallow here, photosynthetic processes are possible for marine life, which attracts more organisms to their primary food sources. Since the land is near shallow waters, discharges of nutrients from the soil are brought into the sea for the marine organisms so that they can use it. Aside from these reasons, cyclic upwellings in the sea also provide fresh and nutrient-rich waters for several species.
Answer: These villi increase the surface area for more efficient food absorption. Within these villi, are present numerous blood vessels that absorb the digested food and carry it to the bloodstream. It is hence from the bloodstream, the absorbed food is delivered to each and every cell of the body.
The process of exchanging gases (carbon dioxide for oxygen) occurs at the lung alveoli. Alveoli are coated with a moist film that dissolves air in the lungs. Oxygen diffuses across the thin epithelium of the alveoli sacs into the blood within the surrounding capillaries.
In exocytosis, a cell releases substances into its environment. During exocytosis, vesicles that contain substances are moved to the cell membrane and fuse with it. This cell membrane function has three results: the total surface of the membrane increases, toxins or waste products are eliminated, and proteins become part of the plasma membrane.
