The statement that describes the ability of the cell membrane to allow various substance to move through is that the cell membrane is preamble and allows only certain substances to pass through.
Explanation:
The plasma membrane is preamble, hydrophobic molecules and small polar molecules diffuse through lipid layer. The integral membrane proteins enable large polar molecules to pass through the membrane.
Some molecules can cross the membrane like hydrocarbons and oxygen. Whereas the large molecules like glucose and sugars cannot cross. The water pass through lipid.

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"
<em>both producers and consumers are the part of ecosystem but finally either directly or indirectly they become food of the decomposers that may be micro-organisms or the larger parasite or saprophyte ..
organisms taking food from living host are parasite while taking food from dead matter are saprophytes..</em>
Hey there!
Here is your answer:
Since there are not options im going to go with what i know:
<u>(Alleles)</u>
<span><u>heterozygous: A,a</u>
</span><u>homozygous: a,a</u>
<u>Therefore the Punnett square should look like this:</u>
<u>A, a</u>
<u>a IA,a I a,a</u>
<u>a IA, a I a, a</u>
Therefore the answer is 50% A,a , and 50% a, a!
If you need anymore help feel free to ask me!
Hope this helps!
