Answer:
The tissues of a leaf needs to have the ability to resist changes in their natural environment so that they can survive
Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air and gets rid of carbon dioxide.
None of those options are correct.
Fungi produce,naturally, antibiotics that will kill or inhibit the growth of bacteria.
This is useful for them to limit competition in their natural environment but it's also useful for us because it will kill bacteria that cause us infections.
The only thing scientists had to do is isolate that antibiotic.
Some antibiotics that were developed from fungi: penicillin and cephalosporins.
To answer this question you must break apart the words given on the right.
“Eco” means life and production. So an ecologist would be someone who studies life and it’s processes. So the correct answer for the first blank would be C. Life Science.
A chemist is one who interacts with day to day elements and sciences that is tactile. So the most appropriate answer would be B. Physical science.
A geologist is someone who studies the earth. As the part of the word “geo,” meaning earth, suggests. So the correct answer here would be A. Earth science.
Finally, “Astro” means space .Astrology is the study of the stars and the sky, for example. So, D. Space science would be the best answer for an astronaut.
I hope all of these are helpful. :)
The pH of blood if pco2 drops to 35.0 mmHg is 7.459
The pH of the blood can be calculated using the Henderson- Hasselbalch equation, which explains the relationship between acid dissociation constant pKa and pH in biological and chemical systems.
pH = pK + log ( HCO3- / ( 0.03 * PCO2 ) )
pK is 6.1 for the bicarbonate buffer system.
HCO3- = 24mm
PCO2 = 35.0 mmhg
pH = 6.1 + log ( 24 / 0.03 * 35.0 )
= 6.1 + log ( 24 / 1.05 )
= 6.1 + log 22.8571
= 6.1 + 1.3590
= 7.459
Hence, the pH of blood is 7.459
