Answer:
The answer Mitochondria and chloroplasts
Explanation:
Answer:
For growing bacteria it is necessary water, a source of carbon and nitrogen, some inorganic salts.
Explanation:
There are plenty of kind of bacteria, even, all of them need water to dissolved their nutrients and to remove the wastes outside of the bacteria body. The source of carbon could be carbon dioxide for some bacteria that do not need a lot of it. In the other hand, there are other bacteria that are feed based on glucose, fructose or another carbohydrate.
Nitrogen sources normally come from air as gaseous element or some inorganic salts like nitrates.
Other bacteria need specific elements like phosphorous, sulfur, zinc, copper, etc.

Answer:
C
Explanation:
This is placing a cell in hyper tonic solution.Therefore, the water potential of the cells is higher than the environment. Hence it lose water to the environment which has a lower water potential, but higher solute potential.
Therefore the loss of fluid by the cell leads to shrinking of the cytosol and it containing organelles. Later the cells collapse.

Esto es colocar las células en una solución hipertónica. Por lo tanto, el potencial hídrico de las células es mayor que el del medio ambiente. Por lo tanto, perder agua al medio ambiente reducirá el potencial hídrico, pero aumentará el potencial de soluto.
Por lo tanto, la pérdida de líquido por parte de la célula conduce a la contracción del citosol y que contiene orgánulos.
Answer:
A) It is the recognition site for a specific transcription factor
Explanation:
Promoter is non-coding DNA sequence responsible for initiation of transcription, as a first and most import step in the regulation of gene expression. Usually changing of promoter nucleotide sequence can lead to loss of promoter function.
In eukaryotic cell, promoter is associated with with other regulatory regions such as enhancers, silencers, insulators. The structure of eukaryotic promoter includes the binding site for the enzyme RNA polymerase, site for the binding of regulation factors (such as TATA box), the transcription start site.
Answer:
they all stay but move 1 and 5 .. 1 goes to 4 and 5 goes to 1
