Julio is studying the evolutionary history of desert cottontail rabbits, sea otters, and grizzly bears. All three species share
krek1111 [17]

Answer:

One way that Julio can explain such differences is that their environments are very similar and therefore the traits that were best suited for their survival were passed on from generation to generation. The traits that each species developed differently would have been due to their diet. Each species has a different diet and certain traits allow them to more easily hunt/gather the food that they need to survive. For example, grizzly bears and sea otters both eat fish as their main diet and therefore have both developed canine teeth, while rabbit teeth are different due to them only eating vegetation.

Please help im having trouble with biology
shusha [124]
Okay, to start off, the basic difference between prokaryotic cells and eukaryotic cells is prokaryotic cells are cells without a nucleus, and eukaryotic cells are cells that contain a nucleus.

So based off that information alone, you can answer #1. Cell A does not have a nucleus (big circle shape), while Cell B does. Therefore, Cell A is the prokaryotic cell.

As for #2, prokaryotic cells and eukaryotic cells DO have similarities despite their differences. For instance, they both have some of the same organelles, like the plasma membrane, ribosomes, cytoplasm, and DNA.

Finally for #3, two differences are that #1, prokaryotic cells have nucleoids while eukaryotic cells have a nucleus, and #2, prokaryotes have circular DNA while eukaryotes have linear DNA. 

Your best bet is finding a visual aid in a textbook or online to help you, so you can better identify organelles and eukaryotic/prokaryotic cells. Also, there are some cheesy videos out there on YouTube which I was forced to sit through in Bio class last year such as the Amoeba Sister's youtube channel which could help. Hope this helped!

What are nodes, internodes, apical buds, &amp; axillary buds?
xxMikexx [17]
Axillary buds are found at the insertion point of leaves and lateral branches in the nodes and give rise to lateral branches and flowers. Internodes are the stem regions between nodes. They lack lateral organs. It can be said that the stem is made up of nodes, internodes and axillary buds tidily arranged.
