Answer:
To conduct an investigation on the effect of organic materials and fertilizers on soil texture, you can follow these steps:
Define the independent and dependent variables:
Independent variable: type of organic material or fertilizer used (e.g. compost, manure, chemical fertilizer)
Dependent variable: soil texture (e.g. water-holding capacity, porosity, bulk density)
Design the experiment:
Choose a representative soil sample and divide it into several equal portions.
Treat each portion with a different organic material or fertilizer.
Control for extraneous variables by maintaining consistent environmental conditions (e.g. temperature, moisture levels) for each soil sample.
Collect and analyze data:
Measure the dependent variable (soil texture) for each soil sample after a set period of time (e.g. after 2 weeks).
Compare the soil texture of the treated samples to the control (untreated) sample.
Use statistical analysis to determine if any significant differences exist between the treatments and the control.

How does competition affect an ecosystem?
Sea anemones compete for the territory in tide pools
Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource (such as food, water, and territory) used by both can be a factor. Competition both within and between species is an important topic in ecology, especially community ecology. Competition is one of many interacting biotic and abiotic factors that affect community structure. Competition among members of the same species is known as intraspecific competition, while competition between individuals of different species is known as interspecific competition. Competition is not always straightforward, and can occur in both a direct and indirect fashion.
According to the competitive exclusion principle, species less suited to compete for resources should either adapt or die out, although competitive exclusion is rarely found in natural ecosystems. According to evolutionary theory, this competition within and between species for resources is important in natural selection. However, competition may play less of a role than expansion among larger clades; this is termed the 'Room to Roam' hypothesis.

The state of a medium helps determine the speed of sound passing through medium
Answers
True. The speed at which sound travels through a medium is determined by the properties of that medium.
What do you mean by sound?
Sound is a type of energy made by vibrations that travel through the air or another medium, like water. It is sensed by our ears and interpreted by our brains. Sound is made up of waves that have different frequencies, which determine the pitch and loudness of a sound.
Factors such as temperature, pressure, composition, and density can all affect the speed of sound in the medium. For example, sound travels faster through warmer air than through colder air, and faster through denser materials than through less dense materials.

Earth than the Su
b. The Moon has a smaller mass than Earth and
the Sun
C. The Moon has a higher density than the Sun
d. The Moon is closer to Earth than the Sun
Answers
Answer:
D
Explanation:
The moon is closer to the Earth so the gravitational pull of the moon has a greater effect on the tides.
The influence of the Moon on the tides on Earth is greater than that of the Sun. This is because the Moon is closer to Earth than the Sun. Thus, the correct option is D.
What are tides?Tides may be defined as a prolonged period of waves that migrate through the ocean in response to the forces endeavor by the moon and sun to the Earth significantly.
Tides generally occur due to the rising and declining of the surface of bodies of water provoked by the attraction of the moon and the sun.
The influence of the tides depends on the distance between the sites of attraction. Due to this the influence of the Moon on the tides on Earth is greater than that of the Sun because the Moon is closer to Earth than the Sun.
Therefore, the correct option for this question is D.

What do you think Niagara waterfall and all other waterfalls have in common?
Answers
Just about every type of waterfall usually has cascades shortly upstream or downstream from it.
What are the advantages of waterfalls?A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf.
The advantages of waterfall development are that it allows for departmentalization and control. A schedule can be set with deadlines for each stage of development and a product can proceed through the development process model phases one by one.
So without waterfalls and their purification of water, we would have no fish to eat, and other animals that live in water would die which would affect the Eco system. Waterfalls also help in turning waste that runs in the water into nutrients which help plants to grow.

By combining information from multiple sources, astronomers can develop a more complete understanding of space.If carbon was the most common element found in the moons and planets, the missing element that would make them similar to Earth is oxygen. Oxygen is a crucial element in the carbon cycle because it combines with carbon to form carbon dioxide, which is then used by plants for photosynthesis. Without oxygen, the carbon cycle cannot function properly, making the planet or moon unsuitable for supporting life as we know it.The electromagnetic spectrum helps us find out the make-up of stars by analyzing the patterns of radiation they emit. Different elements emit radiation at different wavelengths, allowing astronomers to identify the elements present in a star based on the spectrum of radiation it emits.Determining the elements that a planet or moon is made up of can provide valuable information about its geological history and potential for supporting life.

giving 40 points! please help soon <33
Answers
Answer:
use ch.at gpt for homework answers
Explanation:
Let's denote the width of the park as "w" miles. According to the given information, the length of the park is 1/2 miles and the area of the park is 6/8 square miles.
The area of a rectangle is given by the formula: Area = Length × Width
Given that the length of the park is 1/2 miles and the area of the park is 6/8 square miles, we can set up the following equation:
1/2 * w = 6/8
To solve for "w", we can multiply both sides of the equation by 2 (to eliminate the fraction):
2 * (1/2 * w) = 2 * (6/8)
w = 12/8
Now, we can simplify the fraction w = 12/8:
w = (12 ÷ 4) / (8 ÷ 4)
w = 3/2
So, the width of the park is 3/2 miles.
