Explanation:

The mitochondrion (/ˌmaɪtəˈkɒndrɪən/, plural mitochondria) is a semi autonomous double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.

Existing rocks may be heated enough so that the molecules are released from their structure and can move around.

Field study

Explanation:

I took the quiz and got it right. Hope this helps :)

The type of research method that would best answer the given question is field study. The correct option is C.

Field studies are research activities that take place outside of your office or lab, in the context of the user.

There are numerous field-study methods and activities to choose from. Field studies also differ significantly in terms of how the researcher interacts (or does not interact) with participants.

Field research is a qualitative research method that involves observing and interacting with people in their natural settings in order to understand and interpret the social interactions of groups of people, communities, and society.

Field studies provide students with first-hand experiences that promote critical thinking, long-term retention, transferability, positive attitudes toward science, appreciation for nature, and increased scientific curiosity.

Field study is the type of research method that would best answer the given question "How many rivers in Florida have nitrate pollution in them?”

Thus, the correct option is C.

Explanation:

Answer:

Your answer is- Irritability

Irritability is the ability of an organism to respond to the external stimulus. The organism exhibit movement on receiving the stimulus from the internal or the external environment. The most common example of irritability is shown by the Mimosa plant which folds the leaflets when touched. The stimulus is passed on to the entire branch and then whole plant and all the leaflets close.

Answer: Polymerization

Explanation: The linking up of monomers is called polymerization. It is the long chains that give polymers their unique properties.

Answer:

There are no options in this question, however, the equation can be provided. The answer is:

2Na + 2H2O --> 2NaOH + H2

Explanation:

This question is deacribing the equation between sodium (Na) and water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The equation originally is as follows:

Na + H2O --> NaOH + H2

From the above equation, one would notice that it is not balanced because the number of atoms of each element is not the same on both sides of the equation. Hence, to balance the equation, a coefficient is used to make sure the same number of atoms of each element are on both sides.

We have;

2Na + 2H2O --> 2NaOH + H2

Answer:

After 70 years without wolves, the reintroduction caused unanticipated change in Yellowstone's ecosystem and even its physical geography. ... The healthier bear population then killed more elk, contributing to the cycle the wolves started.

Explanation:

The reintroduction of wolves had several positive effects on the ecosystem.

The reintroduction of wolves caused a trophic cascade of events in the Yellowstone national park. This resulted in an increase in the population of beavers and also brought back several forms of vegetation.

The killing of wolves in the 1930s resulted in the shifting of predatory pressure on the elk population. But, they were much less active in winter. They browsed on cottonwood plants and aspen.

But now, the predatory pressure came back on wolves. This keeps the elks more active. This also resulted in an increase in vegetation.

The reintroduction of wolves also resulted in the increase in the population of beavers because of the recovery of willow strands reflourished due to the activeness of the elk.

Therefore, the reintroduction of the wolf population greatly impacted the ecosystem of the Yellowstone national park causing a ripple of positive effects.

Explanation:

While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created. The Electron Transport Chain makes energy ... At the end of the chain the electrons are taken up by oxygen molecules to make water. This is why oxygen is known as the final electron acceptor.

Answer:

Explanation:

during electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space. A chemiosmotic gradient causes hydrogen ions to flow back across the mitochondrial membrane into the matrix through ATP synthase, producing ATP
