Answer:
The dependant variable is the growth of the plants.
Explanation:
The independent variable is what changes the dependent variable.
for example, the type of salt concentration ( Independent variable ) is/ isn't going to change the growth ( dependant variable ) of the plant.
The dependant variable is the growth of the plants.This is the outcome of the experiment in which salt affects the growth of plants.
What are plants?Plants are the eukaryotes means they are multicellular organisms and they belong to the kingdom Plantae. So, the scientific name of plants are Plantae and its domain is Eukaryota.
The plants are of many types such as shrubs, herbs, mosses, ferns, trees and they grow on a particular place by absorbing inorganic substances and water from the soil through the roots.
Plant are also known as autotrophs as they prepares there own food in the presence of sunlight. Due to chlorophyll present in them the plants shows green colour.
Plants are also known as producers because they produce food to feed others.
Therefore, the dependant variable is the growth of the plants.This is the outcome of the experiment in which salt affects the growth of plants.

All pros when conducting a lab experiment except?
a) the scientist can manipulate variables
b) the scientist can control all of the variables
Answer:
I personally believe that lab experiments are useful and an effective way to test and gather data. Even though they can often lack ecological validity and mundane realism they can easily be replicated and results can be retested, helping to prove/disprove data, ultimately leading to the creation of practical applications.
That psychologist can make statements about cause and effect because they involve the deliberate manipulation of one variable while trying to keep the other variables constant, unlike non-experimental methods.Lab experiments can also be replicated due to the standardised procedures and measures, ultimately making it easier to check the reliability of the research/results and prove/disprove results if the research is conducted by another researcher.

the frequency of a drum note is 20Hz. what does this tell you about the drum skin movement
Answer:
The drum skin oscillates 20 times per second
Explanation:
The frequency of a note is dependent on the mechanical activities that occur when it is produced. A drum is beaten in this case. The oscillation of the drum skin transfers sound waves to the air particles which move at the same frequency before reaching our ears.
If the frequency of the sound wave is 20 Hz this means that the wave is oscillating 20 times in one second. For the drum to produce such a sound, the skin must have been oscillating at the same frequency of 20 oscillations per second too.

Explanation:
who created the earth
Explanation:
Hey, there!
It's not obvious that who created the Earth.
Noone can say the answer of who created Earth because Earth wasn't created by any human or any specific creatures.. So, let me give some information about creation of Earth. Many hypothesis has been given by our great astronomers and philosophers. Here, i'm gonna describe some:
Old planetesimal hypothesis: According to this hypothesis there was a huge gaseous mass and comet collided together as a result, a very large amount of matter was thrown out of the sun, which later on cooled and planets are formed.Nebular hypothesis: According to this hypothesis the sun, the earth and other planets were formed by a large whirling cloud of hot gases and dust. When the cloud cooled and grew smaller, it began to spin faster. As the surface of the cloud cooled by radiation, a ring a matter was formed at the equatorial region of it.New plantesimal hypothesis: According to this hypothesis, the gaseous mass didn't collied with comet but they came closer to one another and due to gravity of comet, great tidal rose on gaseous mass. The materials rise up as a large spiral arms. Then the spiral arms were cooled down and broke away from the main mass. Then they were considered to be planets and main mass as the sun. It is modern of old plantesimal hypothesis. Tidal hypothesis: According to this hypothesis, it was also supposed that a comet passed through and had exerted a tidal pull upon a mass. The outer part of the filament escaped into space, inner part came back into the gaseous mass and middle part formed different sizes, which were planets and remaining were sun.Dust-cloud hypothesis: This hypothesis is different tgan above. It says tgat all planets were formed by large cloud of dust and gases. The light of stars pushed the atoms of gases and dust to form a large particals. These particals were attracted to eachother by gravity and began to crowd together. Eventually, a huge ball of materials formed the sun and the solar enegry was produced by nuclear reaction. Other particals remain near the sun and started revolving around it. The huge whirlpools originated in the rotating clouds which formed the smaller gaseous glodsand dust to form planets.This is how the earth was originated or created according to different hypothesis. so, there is no any single people or things that created the earth.

Rachel wants to test how sunlight impacts plant growth over time she will add billing amount of light to different sets of plans what is the independent variable
Answer: sunlight.
Explanation: When trying to establish the level or extent of correlation or relationship which exists between two variables, the variables are classed as independent and dependent variables. The independent variable is referred to as the variable which causes a change in the value of the other variable (dependent variable). It is also known as the explanatory or predictor variable as it lead to changes in the dependent or predicted variable. In the scenario above, the independent variable is sunlight whose impact leads to changes in the growth level of the plant.
