If oxygen levels in the Bay dropped by 90%, the most obvious effect would probably be a decline in fish numbers.

All of the Chesapeake Bay's living things, including the fish, crabs, and worms that burrow into the muddy bottom, require oxygen to thrive just like people do. The majority of scientists concur that dissolved oxygen levels in the Bay must be at least 5.0 mg/L for organisms to survive and grow. However, an animal's oxygen requirements vary based on its size, complexity, and environment.

Worms and clams require dissolved oxygen concentrations of at least 1 mg/L to survive in the muddy bottom of the Bay, where oxygen levels are naturally low.

Dissolved oxygen requirements for bottom-dwelling fish, crabs, and oysters are 3 mg/L or higher.

Migratory fish that are spawning, along with their eggs and larvae, require up to 6 mg/L throughout these delicate life stages.

More oxygen can be held in water the colder it gets. The amount of oxygen that may dissolve in the water decreases as it gets warmer. Salinity plays a significant role in determining the volume of oxygen that a body of water can contain, with fresh water having a higher capacity.

When there are excessive amounts of bacteria or algae in the water, oxygen levels may also be diminished. Once the algae have completed their life cycle and have passed away, bacteria eat them. The bacteria also ingest the oxygen dissolved in the water during this process of decomposition. This can result in lower physiologically accessible oxygen levels, which, in some situations, can cause fish deaths and the demise of other aquatic species.

The radiometric dating of sedimentary rock is not exact due to the fact that sedimentary rock is made up of weathered and eroded bits of other rocks, including igneous rocks.

Radiometric dating relies on measuring the abundance of radioactive isotopes and their decay products within a rock sample. However, in the case of sedimentary rock, the minerals within the rock are typically not the original components but rather fragments from different sources. These fragments may have different ages and could have undergone various geological processes before being deposited as sedimentary rock.

As a result, the different minerals and fragments within the sedimentary rock may have different isotopic compositions and ages. When attempting to date a sedimentary rock using radiometric methods, it becomes challenging to accurately determine the initial composition of the minerals and the timing of their formation.

The most common type of fossils found in Fauna 2 is (A) the Trilobite, which belongs to the class Trilobita. Trilobites were marine arthropods that lived between the Early Cambrian and Late Permian periods. They were abundant and diverse, and their fossils are important for understanding the evolution of arthropods and the ancient marine ecosystems in which they lived.

Trilobites had hard exoskeletons that allowed them to be well preserved as fossils. Their fossils are found in a variety of sedimentary rocks, including shales, limestones, and sandstones. They are usually found as isolated exoskeletons or fragments, but sometimes complete specimens are found in a characteristic curled-up posture.

Although other types of fossils such as snails, bryozoans, forams, and cephalopods are also found in Fauna 2, trilobites are by far the most common and distinctive fossils found in this period.

Therefore, the (A) trilobites are the most common type of fossils. So, it is the correct option.

Two key characteristics of the maturity stage are market saturation and price competition. Here option A and C are the correct answer.

The maturity stage is the third stage of the product life cycle, following the introduction and growth stages. It is characterized by slower sales growth, increased competition, and a need for companies to defend their market share.

Market saturation: In this stage, the market for the product becomes saturated, meaning that most potential customers have already purchased the product. Sales growth slows down as a result, and companies need to find new ways to maintain their market share.

Price competition: As more companies enter the market and competition increases, pricing becomes more competitive. Companies may need to lower their prices to remain competitive, which can lead to lower profit margins.

A reaction requires 2.5 moles of zinc oxide, equal to 202.5 grams.

The mole scale is needed as an indication of the amount of substance or compound, mole is the gram of substance divided by the relative molecular mass (Mr). The formula for calculating the moles of a compound is n = gram/Mr

in question:

2.5 mol of zinc oxide: n = 2.5 mol

Mr zinc oxide : Mr = 81 gram/mol

Then grams of zinc oxide are:

n = grams/Mr

grams = Mr x n

grams = 81 grams/mol x 2.5 mol

grams = 202.5 grams

So, grams of zinc oxide is 202.5 gr.
