Answer:

C) are sequence-specific DNA endonucleases

B) degrade foreign DNA that enters a bacterium.

Explanation:

Restriction enzymes are the proteins that cut the DNA at a specific sequence.

<u>Restriction enzymes are also known as restriction endonuclease produced by bacteria that recognizes a specific sequence on DNA and split it by catalyzing the hydrolysis or addition of water molecule. </u>So, Restriction enzymes are sequence-specific DNA endonucleases.

The biological role of restriction enzymes is to restrict the entry of foreign DNA into the bacterium. <u>Restriction enzymes have the ability to restrict the number of bacteriophage strains that affect bacteria.</u>

Hence, the correct options are "C and B"

Sandra is an avid hiker. She’s found three rocks while hiking near the Camden Gorge. Help her identify which type of rocks they
MaRussiya [10]

Rock A = It is a metamorphic rock that  experienced tremendous heat  and  pressure due to massive,  moving tectonic plates.

Metamorphic rocks are rocks that have been somewhat squished and transformed by heat and pressure. These rocks often have different layers as the rocks go through pressure and are literally look like rocks that have been piled up and then stuck together. The best indicator of this rock being a metamorphic rock is the wavy elongated stripes. The stripes are created from the different rock elements being pressed together over time.

Rock B = It is a sedimentary rock made  primarily from lithification of  organic material.

Sedimentary rocks are rocks that have been formed by different substances that come together due to the different weather conditions. The best indicator of this being a sedimentary rock is how the rock came together and looks like a bunch of shells were glued together.

Rock C = It is an igneous rock that  was formed above  Earth’s surface.

Most igneous rocks have smooth outer layers. These rocks are often made with solidified magma from volcanoes. The best indicator of this being an igneous rock is the indication of it being a solidified piece of magma.

The transport of molecules of a particular solute from inside an animal cell across the cell membrane to the extracellular fluid
Leona [35]

Answer:

the concentration of the solute is lower inside the cell than outside it

Explanation:

This question depicts the process of ACTIVE TRANSPORT, which is the movement of a substance against concentration gradient, hence, requires energy input (ATP) to occur. In this case, transporting a solute from inside an animal cell to the extracellular fluid across the cell membrane always requires energy.

This is because the concentration of solute inside the cell is much lower than that of the extracellular fluid, hence, to move the solutes against this concentration gradient (low to high), energy in form of ATP is required.
