A researcher observes two species of frogs in the same area. Both species have a similar diet. One species breeds in fast-moving

streams, while the other species breeds in ponds. Both species are similar in appearance and have very similar DNA. Which information provides the best evidence that these two species descended from a common ancestor

Answer:

Similar DNA provides us the information that these two species are come from the same ancestors.

Explanation:

DNA is a genetic material which provides us more information about the organisms. In the above example of frogs, both have same DNA and body structure but they are living in two different habitat i. e. one is living in standing water and other is living in fast flowing water. These two species have many characteristics common except habitat so we can say that both species are evolve from the same ancestor.

One gene in the human genome may be expressed at a much higher level than another. Can differences in types of cis elements pres
Oksana_A [137]

Answer:

No, CREs usually don't account for differences in gene expression levels.

Explanation:

<em>Cis</em>-regulatory elements (CREs) are non-coding DNA regions that regulate adjacent gene <em>transcription</em>. They usually do it by binding to transcription factors. They are in charge of influencing the rate of which transcription occurs, and less with how much a gene is expressed. On the other hand, trans-regulatory elements are DNA sequences that encode for upstream regulators that can modify or regulate <em>gene expression levels</em>.

Therefore, cis elements are not really in charge of expression levels, mostly transcription rates of single genes, rather. Trans elements are more involved in expression levels.

What types of materials require a vesicle for export or a food vacuole for import?
Korvikt [17]

Macromolecules or large particles are carried across the cell membrane via vesicles or other intracellular structures. Pinocytosis and efflux are the two types of vesicle transport.

<h3>How does a vesicle leave the cell with its cargo?</h3>

Exocytosis is the process by which cells move components from within the cell to the extracellular fluid. Exocytosis occurs when a vesicle's plasma membrane fuses with it, expelling its contents outside the cell.

The Golgi, also known as the Golgi complex, is a flattening, layered organelle that looks like a stack of pancakes. The Golgi body modifies and packages proteins and carbohydrates into lattice vesicles for "exportation" from the cell.
