Energy and matter are conserved as they can be changed into different forms. This is known as Law of conservation.
What is the Law of conservation of energy and matter ?
The law of conservation of matter and energy states that matter/energy is neither created nor destroyed but can only be transformed from one form to another.
When wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted. This proves the law of conservation of mass. In a torch, the chemical energy of the batteries is converted into electrical energy, which is converted into light and heat energy. This proves the law of conservation of energy.To know more about Law of conservation here

In what year should we expect ocean pH to adversely affect zooplankton population?
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.

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%
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).

a. What information could be useful to include in a warning on an e-cigarette ad?
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?
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:
