Answer:
The history of botany examines the human effort to understand life on Earth by tracing the historical development of the discipline of botany—that part of natural science dealing with organisms traditionally treated as plants.
Some traditional tools of botanical science
Rudimentary botanical science began with empirically-based plant lore passed from generation to generation in the oral traditions of paleolithic hunter-gatherers. The first written records of plants were made in the Neolithic Revolution about 10,000 years ago as writing was developed in the settled agricultural communities where plants and animals were first domesticated. The first writings that show human curiosity about plants themselves, rather than the uses that could be made of them, appear in ancient Greece and ancient India. In Ancient Greece, the teachings of Aristotle's student Theophrastus at the Lyceum in ancient Athens in about 350 BC are considered the starting point for Western botany. In ancient India, the Vŗkşăyurvĕda, attributed to Parăśara, is also considered one of the earliest texts to describe various branches of botany.[1]
In Europe, botanical science was soon overshadowed by a medieval preoccupation with the medicinal properties of plants that lasted more than 1000 years. During this time, the medicinal works of classical antiquity were reproduced in manuscripts and books called herbals. In China and the Arab world, the Greco-Roman work on medicinal plants was preserved and extended.
You will need the following materials to build the model:
1 piece of card stock, 8 inches × 11 inches
1 sheet of printer paper, 8 inches × 11 inches
1 piece of cardboard, 8 inches × 11 inches
a long, shallow plastic container, around 30 inches long, 15 inches wide, and 5 inches deep
tape or glue
a small plate or tray
water
a ruler
a small bag of sand, about 2 pounds
Note that you will need these same materials for task 2. Hold on to them after completing task 1.
Hypothesis and Data Collection
Part A
Select one sheet of card stock, one sheet of printer paper, and one sheet of cardboard.
Use a ruler to draw two rectangles on each sheet. The first rectangle should be 1 inch × 6 inches. The second rectangle should be 2 inches × 3 inches.
Cut out all the rectangles.
Follow the diagram to fold the pieces into houses. Each 6-inch piece will form the walls of a house, and each 3-inch piece will form the roof.
two pieces of paper folded to form the roof and walls of a house
Secure the walls and roof with tape or glue. You should have three houses: one house made of printer paper, one of card stock, and the last of cardboard.
The rest of this activity can get messy. If possible, set up your model outdoors.
Next, use the sand to make a slope on one side of the plastic container. Shape the sand to resemble a sea coast.
Place your houses on the flat surface of the sand. They should be parallel to each other and positioned at the same distance from the end of the slope.
Fill the other side of the plastic container with water.
Place your plate or tray vertically in the water as shown in the diagram. Answer the question below.
a tank containing water and sand and a plate being pushed downward
What will happen to the sand and houses when you push the plate in the water? Do you think one type of house will change more than the others? Write down your prediction.
Now push the plate down and observe what happens on the shore. Repeat the action three to four more times, and watch the sand and the houses. Write down your observations.
Were your predictions about the sand and houses correct?

Explain the process of budding that occurs in some yeasts..
Budding in Yeast.
Yeast cells reproduce asexually by an asymmetric division process called budding. In yeast, budding usually occurs during the abundant supply of nutrition. In this process of reproduction, a small bud arises as an outgrowth of the parent body. The newly created bud divides and grows into a new cell.

Using the five types of relationships discussed in this Lesson, write a paragraph showing these types of relationships with humans. For example, two people might be in competition for the same job.
The types of relationships are predation, competition, commensalism, parasitism, and mutualism. They are more common between animals or organisms than with humans.
The constant interaction that species or organisms have to survive or benefit can be classified into five types of relationships. These are predation, competition, and the three types of symbiosis.
Competition is when two or more species compete for a resource that they need. An example with humans would be two people competing for a scholarship. Predation is when one organism eats the other, this could be a man hunting a deer or fishing. It happens between humans and animals.Commensalism is one of the three types of symbiosis, it is when a species benefits from another one, but this does not affect the benefactor. An example with humans would be the relationship between a patient and a doctor.Parasitism is a relationship where one species benefits from the other harming the other. An example would be a human that lives off the income of another person.In a mutualism relationship, the two organisms benefit from the other; it is an equal relationship. An example between humans would be a friendship.
In conclusion, the types of relationships between different species or the same species can be beneficial for both of them or not. They depend on the resources that each of them needs.

Answer:
There are five relationships that were discussed in this lesson: predation, parasitism, mutualism, commensalism, and competition. An example of predation would be when a human hunts for a deer. An example of competition would be when there is a tournament, and two or more people go against each other. Commensalism could be when you work under a boss and they benefit from you and you aren't harmed. Mutualism is like when you have friends and you both benefit from each other. You pick each other up when you are down, etc. If you have a dog and it gets lice on it that's an example of parasitism. Everyone has different effects.

Which best defines color?
a physical property of matter related to a material’s ability to reflect light
a physical property of matter related to how a material interacts with different wavelengths of light
a chemical property of matter related to a material’s ability to reflect light
a chemical property of matter related to how a material interacts with different wavelengths of light
Answer: It's A.
Explanation: The definition of color is a component of light which is separated when it is reflected off of an object. The appearance of objects or light sources described in terms of the individual's perception of them, involving hue, lightness, and saturation for objects, and hue, brightness, and saturation for light sources.
A color can be best defined as the physical property of matter which is related to a material's ability to reflect light. Thus, the correct option is A.
What is a Color?
Color is the physical property of an object or substance with respect to the amount of light reflected by the object. It is determined visually by the measurement of hue, saturation, and brightness of the reflected light by an object.
Physical properties of the matter may be subdivided into intensive and extensive properties. An intensive property of matter include color, density, temperature, and melting point. It is a bulk property that does not depend on the sample size but the quality of the sample. Reflectivity is a physical property of matter which is related to the amount of light that a material reflects on absorption of light.
Therefore, the correct option is A.

Why is burning fossil fuels not considered carbon neutral
Answer:
Maybe this will help
Explanation:
Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.
