Answer:
The DNA is more closer to bacteria.
Explanation:
Mitochondria and chloroplast are considered as semi-autonomous organelle because they contain their own genetic material. The mitochondria and chloroplast evolution can be explained by the endosymbiont theory.
The DNA of mitochondria and chloroplast are more closely related to bacterial chromosome rather than eukaryotic chromosome. Both the organelle and bacterial DNA are double stranded and their translation can be inhibited by the chloramphenicol. Some of their replicating enzymes also show similar characteristics.
Thus, the DNA is more closer to bacteria.
The answer is <span>a. most living organisms can survive in environments with several different temperature and salinity levels.
</span>Aquatic plants and animals depend on dissolved oxygen for respiration. The other abiotic factors that impact their life in an aquatic ecosystem are temperature, salinity, and flow and they determine the quality of their life. <u>It is not true that most living organisms can survive in environments with several different temperature and salinity levels.</u> On the contrary, a few species can live in <span>environments with several different temperature and salinity levels, for example, some bacteria. The most organism can survive in a specific range of abiotic factors.</span>
Answer:
C. Aldosterone increases sodium reabsorption by increasing the number of Na+-K+ ATPase pumps in the luminal membrane of the proximal tubule.
Explanation:
- Aldosterone hormone is produced by the adrenal gland and mainly carries out its functions in the kidney.Through the aldosterone hormone the body is able to retain more water for the kidney is able to hold more sodium.
- When the plasma sodium levels decrease and the plasma potassium levels increase the production of aldosterone hormone is stimulated for sodium is needed in the .body to maintain the high water levels in the body.
Answer:
The correct answer would be levodopa/carbidopa.
Tolcapone is a drug used as an adjunct to levodopa/carbidopa combination medication.
These drugs are used to treat the symptoms of Parkinson's disease.
Tolcapone is used to inhibit enzyme COMT (catechol-O-methyl transferase).
In the brain, levodopa is converted into dopamine which helps in controlling the movement.
Carbidopa helps in preventing the breakdown of levodopa in the blood which allows more levodopa to enter the brain. In addition, it helps in reducing the side-effects associated with levodopa such as vomiting, nausea et cetera.
