Energy moves from one trophic level to another as organisms feed on one another.
Explanation:
Energy flows from one trophic level to another in a food chain. according to the ten percent law, only ten percent of the total energy passes onto the next trophic level. While studying the energy flow model two aspects should be taken under consideration. Firstly, the flow of energy is unidirectional and passes on from autotrophs to primary consumer and then secontary, tertiary so on. Secondly the amount of energy decreases at succesive trophic level.

Answer:
<em>Food and shelter are the most likely limiting factors in this case.</em>
Explanation:
In a forest, the huge trees act as a source of shelter for the animals that live in that habitat. It protects the animals from the heat of the Sun and extreme cold conditions.
The tress in the forest are the primary source of food for almost all the organisms that live in the forest. Cutting down trees will lead to food scarcity for the animals which inhabit that forest. As a result, the animals will either have to migrate or they will become die due to lack of food.
Hence, food and shelter are the limiting factors in this case.
Answer:
a. positive; negative
Explanation:
Transcription is the process of forming an RNA molecule from a DNA template molecule. In this process, the strands of DNA separate and one serves as a template for RNA, while the other is inactive. At the end of the transcript, the tapes that have been split back together again.
The transcription process is divided into three steps: initiation, stretching and termination
During the stretching phase, transcription chain elongation occurs. In this phase the enzyme called RNA polymerase starts to move through the DNA molecule, unwinding its helix and producing an increasingly lengthened RNA molecule. The already transcribed DNA is rewound almost immediately, recomposing its double helix. This process is called the elongation phase.
During this process, it is believed that positive supercoils are generated ahead of the transcription bubble and and the negative supercoils behind it.
Answer: Increase the surface area.
Explanation:
The mitochondria is an important cell organelle that is found in both the plant cell and animal cell.
It basically aids in the production of ATP, hence also known as the power house of the cell.
The mitochondria is a double membrane system in which the inner membrane of mitochondria helps in increasing the surface area for integral proteins.
It helps in embedding the proteins in the folding known as cristae.
