Chao should use a flat shallow pan filled with a thick liquid that can be heated by a hot plate with pieces of thin plastic sheets floating on top of the liquid. This part of the experiment will best depict plate tectonics because of the variables that can be seen
hope this helps
Dr. Pringle suggests that there's only very few large herbivorous species that can survive in certain area. The reason behind his claim is that according to him there will be only enough food for few large species, so there's natural limitations in the food sources, as there should be enough to support them in order for them to survive.
On the other hand, in Mpala, there's 22 large herbivorous species, which directly contradicts Dr. Pringle's hypothesis. The reason why so many large species of herbivores an survive in Mpala and always have enough food for all of them, is that they have all specialized in eating certain types of plants or parts of plants, thus they are not direct competition to one another, and there's always enough food for all of them.
Answer:
d. transcription factors
Explanation:
Transcription factors are the proteins present in cells that are involved in the regulation of gene expression. The transcription factors may increase or decrease the expression of a gene. Therefore, a transcription factor may serve as an activator or repressor for a gene. These proteins bind to a regulatory sequence present near or within a gene, interact with RNA polymerase or other transcription factors and thereby, affect the transcription initiation.
Since binding of dioxin to certain proteins alter the pattern of gene expression in the cells, these proteins are the transcription factors. For instance, dioxin may bind to a transcription factor and up-regulate the expression of genes which in turn regulate the cell division.
Answer:
primer
Explanation:
Most biological reactions rely on the enzyme to speed up the reaction. In the case of DNA replication, this enzyme is DNA polymerase. a; DNA is a double helix made up of two long chains of deoxyribonucleotides. ... b; a primer is used to start this process by giving DNA polymerase something to bind the new nucleotide to. just for you to see.

The ph of smoke disrupts the natural ph of water( which is 7, the neutral ph) in the atmosphere causing it to become acidic . This is dangerous as it will also have effects on rain and soil ph.
