Researchers use a computer model to simulate an oil spill in the ocean. The model predicts which areas of the shoreline will be most impacted by an oil spill if it occurs in a certain area. What are two limitiations of this model? A. It does not predict a situation that might cause an oil spill to happen. B. It does not show how an oil spill might spread from one area to another. C. It cannot be used to evaluate how an oil spill might affect multiple areas of shoreline. D. It does not show how each species of wildlife would be affected by the oil spill.
Answers
It does not predict a situation that might cause an oil spill to happen.
When oil debris reaches shorelines and shorelines, it interacts with sediments such as beach sand and gravel, rocks and rocks, plants, terrestrial wildlife, and human habitats, causing both erosion and pollution. Waves, currents, and wind bring the oil ashore with waves and tides.
Under certain circumstances, oil spills can be very harmful to seabirds turtles, and mammals, and can also harm fish and crustaceans. Oil destroys the insulating abilities of fur-bearing mammals such as sea otters and the water repellency of bird feathers, exposing them to harsh elements. Coral reefs Corals are also very sensitive to oil contamination. Various studies have shown that damaged coral reefs regenerate very slowly. Oil pollution can also affect entire communities.

Explain what the acoustic measure H1-A3 is. Additionally discuss why a large value of the measure H1-A3 would reflect a breathy voice. (Hint: consider using these terms: vocal fold closure, spectral tilt).
Answers
The acoustic measure H1-A3 represents the difference in frequency between the first harmonic (H1) and the third formant (A3) in a speech signal.
The first harmonic is the lowest frequency component of the voice signal, while the third formant is a resonance frequency that is related to the shape and size of the vocal tract.
A large value of H1-A3 indicates that the third formant is higher in frequency than the first harmonic, which is a characteristic of breathy voice quality.
This is because breathy phonation is associated with incomplete vocal fold closure, which results in a weaker and more turbulent airflow through the vocal tract.
This causes a change in the spectral tilt, which in turn leads to an increase in the frequency of the third formant relative to the first harmonic, resulting in a larger H1-A3 value.

At which location is contact metamorphism least likely to occur
1. divergent boundary
2. convergent boundary
3 .transform boundary
Answers
Contact metamorphism is the result of rising of hot magma, where by contact, other previously solidified rocks also metamorphize. This events occurs in convergent and divergent plate boundaries.
-------------------------------------
Contact metamorphism refers to a localized metamorphism. It occurs in the vicinity of intrusive igneous rocks and results from the term effects of hot magma.
Contact metamorphism occurs under elevated temperatures and low-pressure conditions. It is closely related to magmatism.
It occurs in oceanic dorsals, where the extremely hot magma rising to the surface metamorphizes other previously solidified magmatic rocks.
It is very common to find this metamorphism at both convergent and divergent plate boundaries, where molten rock is produced.
I. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. Also, collisions create volcanic arches and continental arches. In these boundaries, blueschists form by contact and regional metamorphisms.
II. Divergent: New crust is created by the rising molten materials coming from the mantle when two plates separate. A stream of hot material creates a new seabed between the separating plates, producing the sea bottom expansion. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. Chlorite and plagioclase metamorphic rocks are formed by contact metamorphism.

Name three different cells in a leaf that contain chloroplast. Please help
Answers
The LEAF as a photosynthetic organ includes the following cells which contains CHLOROPLASTS
• the palisade mesophyll
• the spongy mesophyll and
• the stomatal guard cells
The LEAFS are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the CHLOROPLASTS of these plant. CHLOROPLASTS are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous CHLOROPLASTS and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain CHLOROPLASTS.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains CHLOROPLASTS which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains CHLOROPLASTS are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.

Two species of barnacles live in shallow areas of the ocean. One species tends to live at the top of rocks and the other lives in the lower areas. Explain how this illustrates the COMPETITIVE EXCLUSION PRINCIPLE?
Answers
The situation in question illustrates the competitive exclusion principle by demonstrating how the two species were forced to occupy different locations due to the fact that they share the same niche (meaning that they occupy the same role in an ecosystem).
The competitive exclusion principle states that two species that occupy the same niche cannot co-exist in the same ecosystem. At the very least, they cannot co-exist while maintaining a stable population value. What this means is that since the two species of barnacles have the same niche, which is to feed on plankton using the same methods, they cannot occupy the same location.
This principle is demonstrated by the question that was given because it shows that despite being in close proximity, the two species of barnacle, which share the same niche, have differentiated to occupy different locations in order to avoid competing for the food source present in one.

Their function is to absorb the sunlight energy to mediate the electron excitation and transport and therefore produce chemical energy which are ATP and NADPH.
