Answer:
1. C. environmental scientists
Explanation:
Environmental scientists serve on matters like the perception of surface methods, assessing alternative energy methods, pollution control and moderation, natural source administration, and the consequences of global atmosphere difference. Environmental issues most ever involve an interaction of environmental, biochemical, and life methods. Environmental specialists bring a methods suggestion to the judgment of environmental obstacles. Key components of an efficient environmental expert involve the capacity to associate space, and time associations as well as quantitative study.
2. A
3. B
Answer:
All the above participate in the ammonia excretion
Explanation:
The amino groups present in the amino acids are required to form the urea. The ammonia disposal takes place un the liver by the urea formation and is excreted in the kidneys by urine. When free ammonia is produced in peripheral tissues, it is transported to the liver by glucose -alanine cycle, alanine in transported in the blood to the liver, where is converted into pyruvate.
Another pathway is by glutamine synthase/glutaminase system. The storage and transport of ammonia to the liver is glutamine from glutamate by glutamine synthetase: NH3 + glutamate → glutamine once in the liver glutamine is transformed into glutamate again by glutaminase enzyme: glutamine → NH3 + glutamate.
In the liver takes place the urea cycle, the amino acids transported into the liver can be converted to aspartate. This aspartate enters the urea cycle forming an intermediate of the cycle, and the final product is urea that is excreted by urine.
Answer:
it's 4/15
Explanation:
because we need to diminish 2/3 on 1'5 to find the pattern then dimininsh 1/5 again to the difference of the first 2 fraction to get the answers
Answer:
b. Ebola and Lassa are both caused by viruses.
Explanation:
Ebola fever is caused by the Ebola virus which is an enveloped virus and is a member of<em> Filoviridae</em>. Ebola virus infection is 80% fatal. The incubation period for pathogen ranges from 2 to 21 days. Symptoms of the infection are fever, muscle and joint ache, stomach pain, bleeding, etc. Lassa hemorrhagic fever is caused by the Lassa virus. Infection with the Lassa virus causes fever, malfunctioning of the gastrointestinal system and bleeding.
