6. If you are given a piece of white marble and a piece of white quartzite what test can
you do to determine which is which? What results will you get?
Answers
Answer:
Quartzite is a metamorphic rock formed when quartz-rich sandstone or chert has been exposed to high temperatures and pressures. Such conditions fuse the quartz grains together forming a dense, hard, equigranular rock. The name quartzite implies not only a high degree of induration (hardness), but also a high quartz content. Quartzite generally comprises greater than 90% percent quartz, and some examples, containing up to 99% quartz, and are the largest and purest concentrations of silica in the Earth's crust. Although a quartz-rich sandstone can look similar to quartzite, a fresh broken surface of quartzite will show breakage across quartz grains, whereas the sandstone will break around quartz grains. Quartzite also tends to have a sugary appearance and glassy lustre. The variety of colours displayed by quartzite are a consequence of minor amounts of impurities being incorporated with the quartz during metamorphism. Although quartzite can sometimes appear superficially similar to marble, a piece of quartzite will not be able to be scratched by a metal blade, and quartzite will not fizz on contact with dilute hydrochloric acid.Explanation:

In what year should we expect ocean pH to adversely affect zooplankton population?
Answers
The year we should expect ocean pH to adversely affect zooplankton population is 2030.
What are zooplanktons?Zooplankton is a small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
Ocean acidification may affect zooplankton directly by decreasing in pH, as well as indirectly by trophic pathways, where changes in carbon availability or pH effects on primary producers may cascade up the food web thereby altering ecosystem functioning and community composition.

Explain how nitrate ions help plants to grow.
Answers
Answer:
Explanation:
Both nitrate ions and ammonium ions can be taken up by plants (some prefer one to the other). These ions provide nitrogen for the plant to make its own amino acids for protein synthesis. Except in very high nitrogen soils, the addition of extra nitrate will stimulate plant growth.
Nitrogen is an essential macronutrient that is a component of many essential molecules, such as amino acids, proteins, nucleic acids, and chlorophyll.
What are the roles of nitrate in the growth of plants?Nitrate ions are essential nutrients for plant growth and development. Nitrogen is the fourth most abundant element in plants and is crucial for the growth of leaves, stems, and roots.
Plants require nitrogen in the form of nitrate because it is the most oxidized. It is an easily available form of nitrogen for plants to take up from the soil. Nitrate is absorbed by plants through their roots and transported to the plant cells, where it is used to synthesize amino acids, proteins, and other essential molecules.
Nitrate plays a crucial role in the process of photosynthesis, which is the process by which plants convert sunlight into energy.

What do you mean by energy pyramids?"It is a graphical representation of the energy found within the trophic levels of an ecosystem."The producers have highest energy whereas the top-level organisms would have the lowest energy because energy decreases by 10% while moving from lowest to upper levels.So, the energy pyramid is always upright.Hence, the correct option is A.

19. Use a Punnett Square to simulate a Bb x Bb cross between two flowers.
What is the probability that one of the offspring from that cross will have only the b factor:
a. 50%
b. 75%
c. 100%
d. 25%
Answers
25 % is the probability that one of the offspring from that cross will have only the b factor. So, the correct option is (D).
What is Punnett Square?
A Punnett square is defined as a specialized tool derived from the laws of probability that is used to predict the likely offspring from a cross or mating between two parents.
An example of a Punnett square which is shown in the attached image shows the results of a cross between two purple flowers, each with a dominant factor and a recessive factor.
Only one in four plants or 25% of the plants had white flowers (bb) containing only b while The other 75% have purple flowers (Bb, Bb), because the purple factor (B) is the dominant factor. This shows that purple color is the dominant trait in the plant.
Thus, 25 % is the probability that one of the offspring from that cross will have only the b factor. So, the correct option is (D).

Why do classification systems change over time?
O Scientists find new evidence in their studies.
O Scientists use old methods of classification.
O Scientists repeat experiments and find no changes.
O Scientists find similar evidence to previous work.
Answers
Classification systems change over time because scientists find new evidence in their studies. So, the correct option is (A).
What is Classification System?There are many types of classification systems that are used for different purposes. The classification of organisms takes place in the form of a classification system called Linnaean classification.
Linnaean classification involves the use of organisms grouped using a hierarchy called taxa which includes taxonomic levels and taxonomic groups that animals are placed in based on their characteristics and even shared ancestry.
The different levels of biological classification are as follows:
Species » Genus » Family » Order » Class » Phylum » Kingdom » Domain
It changes over time as scientific studies find new evidence.
Thus, classification systems change over time because scientists find new evidence in their studies. So, the correct option is (A).
