(b) Identify the dependent variable in the experiments. Identify a control group missing from the second experiment. Justify the
hammer [34]

Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.

A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.

A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.

A bacterial infection of the periodontium that causes rapid attatchment loss and poor response to periodontal therapy has a grade of Aggressive periodontal disease

<h3>Periodontium </h3>

The cementum, gingiva, periodontal ligament (PDL), and alveolar bone make up the complex structure known as the periodontium. The periodontium's main purposes are to protect the underlying structures of the tooth from the oral microflora and to enable the tooth to connect to the bone.

An orthokeratinized or parakeratinized stratified squamous epithelium makes up the gingival epithelium. The gingiva, which has connective tissue and epithelial components, covers the supracrestal root surface and the alveolar bone. As it lines the gingival sulcus close to the tooth surface (enamel or cementum) and subsequently joins to it with hemidesmosomes, the gingival (oral) epithelium develops into the sulcular epithelium and junctional epithelium.

What is true about two different cell types in the body?
Irina18 [472]

Answer:

Read It and Understand

Explanation:

There are over 200 different cell types in the human body. Each type of cells is specialised to carry out a particular function, either solely, but usually by forming a particular tissue. Different tissues then combine and form specific organs, where the organ is like a factory where every type of cell has its own job.
