These bones are called the ossicles. When the eardrum vibrates, it shakes three little bones called the ossicles. These are the smallest bones in your body.
Answer:
1) Build walls along steep slopes -> Prevent soil erosion
2) Purify water to remove industrial byproducts and other waste products -> Prevent aquatic ecosystems from declining
3) Introduce tough laws to ban activities such as hunting, fishing, and poaching -> Prevent explotation of species
Explanation:
1) Build walls along steep slopes -> Prevent soil erosion
In steep slopes, the risk of erosion is more elevated in comparison to other land formations. Preventing soil erosion is fundamental to prevent detrimental damage to the environment, infrastructure, and even communities of a certain region. Building walls, terraces, and adding vegetation to steep slopes highly contribute to the prevention of erosion.
2) Purify water to remove industrial byproducts and other waste products -> Prevent aquatic ecosystems from declining
First and foremost, mitigating aquatic pollution - industrial waste and products - is essential to keep an aquatic ecosystem healthy. In addition, methods of water purification as well as biotechnological application such as the use of bacterial strains that consume pollutants is fundamental to remove industrial waste and prevent the decline of freshwater and marine species.
3) Introduce tough laws to ban activities such as hunting, fishing, and poaching -> Prevent explotation of species
Overhunting and overfishing leads to the decline of economically and ecologically-important species. The introduction of new laws that ban illegal hunting, overfishing, and poaching in addition to natural protected areas lead to the prevention of the explotation of species, enabling them to thrive and reproduce in their habitats.

I got it right on edmentum
They are not valid because the student did not control all the variables that can affect plant growth
They are valid because the dependent variable caused a change in the independent variable.
They are not valid because the time frame to grow a plant is too short.
They are valid because the dependent variable caused a change in the independent variable.
Answer: Option C
Explanation:
The validity of a student’s result is basically based on how the dependent variable caused a change in the independent variable. A dependent variable is one which a scientist produce a variable and finds means to explain it in a proper way. An independent variable is one that is formed to compliment the dependent variable.
When the independent variable increases it causes decrease or increase in dependent variable. A intermediate or intervening variable is found which helps explain about the changes happening between the Independent and interdependent variable.
Answer:
Option (c) ''They are valid because the dependent variable caused a change in the independent variable'' is the correct answer.
Explanation:
The dependent variable is the one which is the center of observation. It is changed during the reaction and affected by it. When we measure the value of the reaction we always measure the dependent variable.
The independent variable is the one that is changed to cause the change in the value of the dependent variable. We can say that the dependent variable depends on independent for its reaction.
So dependent and independent variables are correlated with each other which tells the authenticity of the experiment.
Slits are necessary at the bottom of a seed box because they allow the water to flow through and irrigate. Happy I could help :)
Minerals have the property of cleavage to split into different parts, particular colors to particular minerals, and magnetism due to presence of electrons. Thus, the correct option is D.
Minerals are the elements which are found in the Earth crust and in foods that our body need to undergo development and function. Some of the essential minerals for health of a living organism include calcium, phosphorus, potassium, sodium, chloride, copper, iodine, etc.
Minerals show the property of cleavage, through this large pieces of minerals breaks into smaller ones which can be further used in different processes.
Different minerals have different colors which can be changed due to environmental conditions and reactions.
Minerals show magnetism. It is property responsible for the magnetic behavior of minerals due to presence of electrons in the valence shells.
Therefore, the correct option is D.
