Answer:
I believe the answer is D
The answer is D because they speard apart or interact in all boundaries.
The mass percent of oxygen in Barium perchlorate is is 38%.
The molecular mass of Barium perchlorate (Ba(ClO4)2) is 336.2282 g/mol.
Percent composition of Oxygen will be = [(Molecular mass of Oxygen X 8)/ Molecular mass of Barium perchlorate] X 100%
= [(15.99 X 8)/336.2282] X 100% = 38%
No, the biodiversity is not as high in a city park as it is in a farm or rainforest
because, in an urban city park, only the species with the most general habitat and resource requirements have generally remained in the urban park.
<h3>What is Biodiversity ?</h3>
“Biodiversity” not only refers to the number of individual species, but also the genetic variety within and between species and the diversity of ecosystems and regions.
- City Parks are less likely to have biodiversity richness as compared to a farm or a rainforest.
- This is because these parts are artificially created and a lot of naturally occurring flora and fauna are modified in the process. This results in dilution of biodiversity-rich place.

Answer:
The correct answer is - option a. positive.
Explanation:
Nittarte reduction is the test for the determinantion of the production of nitrate reductase enzyme through various test. One of the test is trommsdroff test.
This test involves trommsdroff reagent and dilute sulfuric acid that produce blue color if the reduction occurs and reductase present. This color is formed due to the conversion of ammonia to nitrate.
The correct answer is - option a. positive.
