Answer:
a high cardiac output and high peripheral resistance
Explanation:
Two factors affect the strength of the blood and consequently the blood pressure: cardiac output and peripheral resistance.
Blood pressure is determined by the product of cardiac output and peripheral vascular resistance. In normal individuals there is a spectrum of variation in cardiac output with concomitant peripheral resistance responses for a given blood pressure level. However, increased heart rate results in increased cardiac output, which increases blood pressure, leading to hypertension.
Answer:
Plants can't use N2 as is so the first option is wrong. They do have relationships with bacteria that live in nodules of the root and convert the nitrogen into ammonia, a usable form for the plants. So the second option is correct. There are bacteria living in the soil as well that convert nitrogen to ammonia so technically option 3 is also correct. Again, nitrogen if present in water would be in the form N2 which is not usable by plants so 4 is wrong.
These are correct:
use bacteria to convert nitrogen to usable form
In obtain usable nitrogen compounds from the soil
Bacterial cells don’t have nucleus so they are prokaryotic. Eukaryotic cells have a nucleus.
to reproduce simply because they need to reproduce
