Biology
1 answer:
snow_lady [41]3 years ago
7 0

Answer:

e. bacteria producing vitamin K

Explanation:

Microbial antagonism basically refers as microbes versus microbes i-e the indigenous microflora serve a beneficial role by preventing other microbes from becoming established in or colonizing a particular anatomic location in the body.

As all the options mentioned, refers to the microbial antagonism except option E as the normal microbes protect the host by :

1) Producing acids.

2) Bactreocin production

3) By occupying the niches that the pathogens may occupy.

But the microbes cant compete with other microbes by  producing vitamins and growth factors that can be utilized by the host.

Hence option E is the right answer.

Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary produ
Katen [24]

Answer:

The answer is C.

Explanation:

Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.

The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.

Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.

Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.

Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.

I hope this answer helps.
