Answer:
C
Explanation:
because the plants are farther down lol
Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.
What are fossils?The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.
The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.
The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.
Therefore, option C. the plants existed prior to the Brachiopods.

Identy three advantages and three disadvantages of bioplastics
Explanation:
Advantages of bioplastics
1.Less oil is used to produce petrochemical (oil-based) plastics which pose a great risk to the environment.
2.The common bioplastics can be injection molded and shaped to take the same form as traditional thermoplastics. In some cases, the bioplastics are stronger and lighter, too, so they are not necessarily only suitable for very niche applications.
3.Bioplastics are more marketable, for example, their usage may improve the value-add of a product through a green marketing campaign. After all, studies have shown that ‘80% of European customers want to buy products with a minimal impact on the environment,’ so bioplastics may represent a useful argument for brands.
Disadvantages of bioplastics
1.First, bioplastics are generally NOT cost-competitive compared to their oil-based counterparts. They are generally two or three times more expensive than the major conventional plastics such as PE or PET, and their production is plagued by low yields and being expensive. This disadvantage should be less acute when manufacturing plants become larger and benefit from economies of scale. A good example is Braskem’s 200,000-tonne bio polyethylene plant (equivalent to about 20% of the world’s current bioplastics production).
2.There is a concern that bioplastics based on terrestrial crops could harm food supplies; however, new innovations using food waste could be helpful in this regard and the concerns would seem to be unfounded as: ‘Perhaps 300,000 hectares are used to grow the crops which the industry processes into plastics. For comparison, this is about 0.02% of the world’s total naturally irrigated area available for cultivation. Even if half the world’s plastics were made from crops grown on food land, the industry would only require 3% of the world’s cultivated acreage.’
3.Crop-based bioplastics require fertile land, water, fertilizers, and are reliant on weather conditions. This means that the supply of raw materials for bioplastics are at risk of natural phenomena, such as drought.
Answer:
Three advantages of bioplastics:
1. Saving fossil fule
2. Reduction of greenhouse gas emission
3. Reclamation of by-products
Three disadvantages of bioplastics:
1. It won't biodegrade in a landfill
2. It contaminate plastic recycling streams
3. It encourage people to litter more

Fire reproduces if a spark from the original fire as it lands on another object. is it evidence or reasoning?
Answer:
reasoning
Explanation:
Fire reproduces if a spark from the original fire as it lands on another object is reasoning.
What is the reasoning?Reasoning is the ability or process of thinking and process thing in a logical and factual way. The use of a reason for a situation is reasoning and it is a sensible way of thinking.
Fire needs oxygen to spark up and fire up. When there are good ventilation and fire breaks up and burns with full light and heat. If the spark of fire burns other objects, it also burned up due to fire. This is the proper and factual reason for burning a fire.
Evidence is when given some evidence for the given statement but in the statement, the evidence is not given, just a reason is given for the burning of fire.

what is role of the stomach in the human digestion system
Explanation:
The stomach is a hollow organ, or "container," that holds food while it is being mixed with stomach enzymes. These enzymes continue the process of breaking down food into a usable form. Cells in the lining of the stomach secrete a strong acid and powerful enzymes that are responsible for the breakdown process. When the contents of the stomach are processed enough, they’re released into the small intestine.
Answer:
first the stomach secretes the gastric juice which is made up of digestive enzymes and digest the hydrochloric acid and plays a big role in digesting nutrients.

Scientists have determined that the pH of seawater can’t physically drop below approximately 7.9 because of its chemical properties. For this reason, some people argue that the term “ocean acidification” is not quite accurate. Do you agree? Explain your reasoning using the pH scale and these graphs showing the acidity trends in Bermuda, Hawaii, and the Canary Islands.
Answer:
The word acidification can be misleading because a pH of 7.9 is still considered slightly alkaline. However, as the graphs in these three locations show, as CO2 rises, the pH drops, moving in the direction of the acidic end of the pH scale.
Explanation:
“Ocean acidification” is occurs in various parts of the world.
I don't agree with the statement that “ocean acidification” is not quite accurate because it happened due to more release of carbondioxide gas in the atmosphere which is dissolved in the ocean or sea water.
When the carbondioxide gas dissolved in water, it produces carbonic acid which definitely changes the pH of the ocean water tends to acidic so in my opinion ocean acidification occurs in various parts of the world.

Complete a dichotomous key for the 10 leaves on the common leaves sheet
A dichotomous key might be considered a significantly useful tool to classify organisms. The key provides an easy and fast way for identification by describing different morphological traits, leading you to the correct taxonomic classification.
When you have an organism -or part of it-, and you need to identify it taxonomically, you use a dichotomous key. The key provides morphological descriptions about different taxonomic groups in an easy way to identify these traits in your individual.
It is simple to read a dichotomous key. The term dichotomous refers to how information is provided. You will always have two options (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism. The key describes specific morphological traits of organisms that are useful for differentiation.
Probably you might need an atlas or a dictionary to understand some of the technical terminologies. You will also need to carefully observe your specimen, to get to distinguish different traits. If the specimen is too small you might need a loup.
Let us analyze simple example using a group of 5 organisms. Let us assume that you do not know their names, and you need to know what is the individual in the red circle (You will find it in the attached files).
Dichotomous key
Statement 1a ----------- The organism is a vertebrate ----------- Frog
Statement 1b------------ The organism is invertebrate ----------- Go to 2
Statement 2a ---------- The organism has a multisegmented
and elongated body, with too many ----- centipede
legs.
Statement 2b ---------- The organism has a relatively short body
and with fewer legs ------------------------------ Go to 3
Statement 3a ----------- The organism has 8 legs ----------------------- Spider
Statement 3b ----------- The organism has 6 legs ----------------------- Ant
As you can see, this a very simple example, but ilustrates how the key provides enough information for you to reah the correct option.
