Answer: essay part

Explanation: I couldn't list eight products but here is my essay on a wool scarf. may not be the best but here:

_________________________

I chose a wool scarf.

wool is made mainly from the coat of a sheep, however, in other cases they can come from a alpacas, goats, and rabbits.

Sheep that have been domesticated and kept as livestock are frequently seen roaming around farms and other green areas. However, you can find wild sheep throughout North America, Central Europe, and the Middle East. Anywhere from mountains, deserts, or a sizable area can be home to sheep, depending on the species.

Sheep are naturally adapted to upland environments and harsh weather, which enables them to flourish where other mammals might find it difficult to survive. In the Middle East, Asia, Central Europe, and North America, where they live in steep hilly terrain, wild sheep are most frequently encountered.

Sheep are extremely reliant on their owners; they rely on them for food, protection, and health maintenance. Additionally, sheep rely on one another for safety

Wild sheep are susceptible to habitat destruction, poaching, and trophy hunting. Sheep can be found at research facilities and medical colleges where they are exploited for brutal tests. Sheep farmed for their wool, meat, and milk sometimes live in subpar conditions and lambs may even have their tails painfully "docked."

A dentist wants to know whether posters of calming nature scenes will reduce patient anxiety. Which of these is the most important Confounding Variable in this experiment?

a) the age of the patient
b) a reduction of anxiety
c) how crowded the waiting room becomes
d) both a and c

Answers

Answer:

d

Explanation:

The most important confounding variable in this experiment is d) both a and c.

Confounding variables are factors that are not directly controlled or manipulated by the experimenter but can influence the relationship between the independent variable (calming nature scenes) and the dependent variable (patient anxiety). They can introduce alternative explanations for the observed results.

In this experiment, the age of the patient (variable a) and how crowded the waiting room becomes (variable c) are both potential confounding variables. Here's why:

a) The age of the patient: Different age groups may respond differently to calming nature scenes. For example, younger patients might have different levels of anxiety compared to older patients. Age-related factors such as life experiences, previous dental visits, or personal preferences may influence anxiety levels and responses to the nature scenes. If the age distribution is not controlled or accounted for, it could confound the relationship between the nature scenes and anxiety reduction.

c) How crowded the waiting room becomes: The level of crowding in the waiting room can create a different environment and affect patient anxiety levels. A crowded waiting room may increase anxiety due to the lack of personal space or increased social interactions. On the other hand, a less crowded waiting room might provide a more relaxed environment. If the level of crowding is not controlled or accounted for, it could confound the relationship between the nature scenes and anxiety reduction.

Considering both variables a and c as potential confounding variables is important to ensure that any observed effects of the calming nature scenes on patient anxiety are not solely attributed to age or waiting room crowding. Controlling for these variables or including them as factors in the experimental design or analysis can help isolate the true effect of the nature scenes on anxiety reduction.

3. a plant cell will have chlorophyll and cell walls, animal cells lack cell walls and chlorophyll

4. the mitochondria creates energy for the cell through ATP

5. Nucleus

Answer:

Explanation:

1. Which cell is more sophisticated: prokaryotic or eukaryotic?

Eukaryotic Cells are more sophisticated because of multiple factors. One such factor is the fact that Eukaryotic Cells have a nucleus that houses the DNA while the DNA of Prokaryotic Cells are in the cytoplasm. Eukaryotic Cells also have organelles that carry out a variety of functions (Mitochondria, Ribosomes, Endoplasmic Reticulum) whereas Prokaryotic Cells have only the basic organelles (in most cases only Ribosomes).

2. Give one characteristic you could use to determine whether a cell is prokaryotic or eukaryotic.

The presence of a Nucleus. Prokaryotic cells don't have a nucleus, while Eukaryotic Cells do.

3. Give two characteristics you could use to determine whether a cell is a plant or animal cell.

The presence of a central vacuole (plant cells have a central vacuole but animal cells do not).The presence of a cell wall (plant cells have a cell wall but animal cells do not).

4. Explain the function of mitochondria.

The mitochondria are considered the 'powerhouse' of the cell. This is because it is the site of most of the respiratory process which produces energy for the cell in the form of ATP.

5. Give the name of the organelle that manages or controls all the cell functions in a eukaryotic cell.

The Nucleus is considered the 'brain' of the cell because it directs all of the cell's functions.
