Which researcher proposed that dreams are a chance for problem solving? A. Sigmund Freud B. Matthew Wilson C. Rosalind Cartwright D. J. Allan Hobson
Answer:
The answer is Rosalind Cartwright.
Explanation:
A researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.
What is Problem-solving?Problem-solving may be defined as an instance of illustrating a problem that significantly determines the consequences of the problem along with identification, prioritization, and selection of alternatives for a solution; and implementing a solution.
Rosalind Cartwright was a neuroscientist who proposed the theory of dreams with respect to the chance for problem-solving. She hypothesized the complete mechanisms of dreaming which is particularly based on REM sleep. It is a way to process emotions, experienced during the day.
Therefore, a researcher who proposed dreams which are a chance for problem-solving is Rosalind Cartwright. Thus, the correct option for this question is C.

Which role of protists has the most positive effect on maintaining the plant population in an ecosystem?
Answer:
Protists decompose dead materials, returning nutrients to the soil.
Explanation:
The role of protists that has the most positive effect on maintaining the plant population in an ecosystem is that they are primary producers.
What are protists?A protist is a single-celled organism that exists within various environments, such as water, soil, and animal hosts. They may also be either heterotrophs or autotrophs, based on their feeding habits.
Protists that are heterotrophic consume other organisms or dead organic material to obtain the nutrients they need to survive, while those that are autotrophic are primary producers that use energy from the sun to convert carbon dioxide into organic compounds, which then make up the foundation of many food chains.
Proteins that are primary producers have the most positive effect on preserving plant populations in an ecosystem. They play an essential role in maintaining the plant population in an ecosystem by serving as the main source of food for herbivores.
The food chain in any ecosystem begins with primary producers, such as protists, which transform energy from the sun into organic matter, making them an essential component of the ecosystem.

This illustration of a cell has a label. If there were no label, how could you tell that this cell is a plant cell and not an animal cell?
Group of answer choices
The cell has a nucleus.
The cell is surrounded by a cell membrane.
The cell is surrounded by a cell wall.
The cell contains cytoplasm.
Answer:
the cell is surrounded by a cell wall
Explanation:
only plant cells have a cell wall.
Answer:
The cell is surrounded by a cell wall
Explanation:
FIrst off, we can eliminate the first option because all cells have a nucleus.
Second off, all cells have a cell membrane, but animal cells DON'T have cell walls, which makes it option 3.
Finally, it's not "The cell contains cytoplasm due to both animal and plant cells having them.

why might one type of coal contain more energy than another type of coal?
I think because of the strength of the coal, and the material. That makes a big difference, opinion wise.
Because it has a higher carbon content and/or a greater amount of other energy-rich components such as hydrogen and sulfur.
Why some coals have more energy than others?The amount of energy in coal can vary due to differences in the organic matter from which the coal was formed, such as the amount of plant material, the type of plants, and the amount of time the plant material was exposed to heat and pressure.
Additionally, the formation process of coal can also affect the energy content, with coal formed under higher pressures and temperatures typically containing more energy than coal formed under lower pressures and temperatures.

How does greenhouse effect, affects biodiversity and gradual extinction
Answer:
Greenhouse gases let the sun’s light shine onto the Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth’s climate comfortable. Without it, surface temperatures would be cooler by about 33 degrees Celsius (60 degrees Fahrenheit), and many life forms would freeze.
Explanation:
Essential nutrients move through a cell membrane by both passive transport and active transport. Which of the following correctly describes the transport of materials across a cell membrane?
Answer:
This question lacks options, the options are:
A). Active transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
B). Passive transport requires chemical energy to move nutrients from areas of low concentration to areas of high concentration.
C). Active transport moves nutrients from areas of high concentration to areas of low concentration without the use of chemical energy.
D). Passive transport moves nutrients from areas of low concentration to areas of high concentration without the use of chemical energy.
The answer is A
Explanation:
Transport of materials across a cell occurs via passive transport or active transport depending on whether energy input is required or not to facilitate the movement.
- Passive transport is the transport of materials e.g nutrients from areas of high concentration to areas of low concentration i.e down a concentration gradient, without the use of chemical energy (ATP).
- On the other hand, active transport requires chemical energy (ATP) to move nutrients from areas of low concentration to areas of high concentration i.e against concentration gradient.

What would happen if the Golgi bodies in the cell were destroyed?
The cell would not be able to digest or break down the materials left over from protein creation.
Explanation:
Without a Golgi apparatus, there would be no lysosomes in a cell. Subsequently, the cell would not be able to digest or break down the materials left over from protein creation. This would create a lot of excess junk within the cell. If this happened, the cell wouldn't be able to live for very long.
