<span>Let's look at all the statements:Which of the following statements is true?
Parts of an ecosystem only include biotic factors such as plants and animals. - this is not true, it also includes abiotic factors, such as stones
If a common plant in an ecosystem becomes diseased, the ecosystem may become unbalanced. - this is the true statement! it could be a source of food for other animals, and thus it could influence the population of other species
Abiotic factors include decomposers such as fungi and bacteria. - this is false, those are biotic factors.
Tundras have a high diversity of species. - this is not true - compared to the rain forest, for example, tundras are not very diverse</span>

Hope this helps!

Answer:
Observations; control. 
Explanation:
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an  observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology. 
On the other hand, a control experiment  can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same  situation by the scientist without involving or using the suspected condition.
Hence, science rejects any hypothesis not supported by observations and the results of control experiments.
<em>This ultimately implies that, for any hypothesis to be acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems.</em>
 
        
             
        
        
        
Explanation:
Primary succession starts off with the modification of a previously unoccupied area along with increasing variation- this occurs in barren areas devoid of life like sand dunes, and lava flows. Communities in a primary succession include:
-barren rock
-bacteria and fungi
-mosses and lichen
Further Explanation:
Succession involves small scale changes within a community that occur repeatedly over the life of that community.
Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:
- colonizing species exploiting uninhabited areas (Primary succession)
- becoming a habitable and increasingly complex community
- there is increased diversity of organisms (Secondary)
The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.
However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.

Answer is : C, increase the surface to allow more space for ATP synthesis.
As it produces large amounts of ATP through oxidative metabolism of pyruvates, which are produced by glycolysis.
The main job of mitochondria is to perform cellular respiration.  This means it takes in nutrients from the cell, breaks it down, and turns it into energy.  This energy is then in turn used by the cell to carry out various functions.
Each cell contains a different number of mitochondria The number present is dependent upon how much energy the cell requires.  The more energy a cell needs the more mitochondria that will be present. Cells have the ability to produce more mitochondria as needed.  They also can combine mitochondria to make larger ones.
The most prominent roles of mitochondria are to produce the energy currency of the cell, ATP (i.e., phosphorylation of ADP),  through respiration, and to regulate cellular metabolism.The central set of reactions involved in ATP production are collectively known  as the citric acid cycle, or the Krebs cycle. However, the mitochondrion has many other functions in addition to the production of ATP.
