If one were to cut the plasmid DNA with Hindill, Apal, and Smal, how large is each
tiny-mole [99]

A linear shaped piece of DNA strand is obtained when a plasmid is cut HindIII, Apa1, and Sma1.

Explanation:

Restriction enzymes are endonucleases which enzymatic proteins which can cut a DNA at specific sequences at particular recognition sites. The sequences recognized by these enzymes are usually palindromic that occurs for a definite length (6 bp, 4 bp, or 8 bp).

They can either be blunt cutters or sticky end cutters. APA1, SMA1, and HindIII are all restriction enzymes which can cut a circular plasmid at specific locations.

These restriction enzymes bind with the DNA at specific locations and cuts them to give linear strands of DNA either with a blunt or a sticky end.

Which do you think would adapt and survive overtime to a mass extinction? A starfish or an eel?
Harlamova29_29 [7]

Answer:

Starfish

Explanation:

This is an opinion questions, so there really isn't a right or wrong answer.  You could just as easily choose Eel.  Your task is to pick one and defend your reasoning.

I chose starfish because starfish have a long history of demonstrated adaptability to a wide variety of conditions.  Their armored skin protects them from a variety of predators, as does the poison that many of them contain.  They have the ability to regrow limbs, and even regrow entire starfish from certain body parts.  When it comes time to breed, starfish meet together in groups.  Each female releases a few million eggs from the gonads in each of her arms.  Each male then releases billions of sperm from each gonad in each of his arms, thus covering the eggs with sperm to fertilize them.

In order for a sedimentary rock (made of particles) to form, what must occur?
wolverine [178]
First, preexisting rocks must weather/erode, forming the sediment that will eventually form the sedimentary rock. Then, that sediment must settle someplace, and over a long period of time, pressure begins to build. This causes the sediments to become compacted. After a long period of time (and a lot of pressure), the sediments cement together and form a sedimentary rock. In a nutshell, sedimentary rocks form through compaction, cementation, and eventually... lithification.
