The cell membrane in humans and animals behaves most like the second option. A police officer who allows select people to enter and leave a crime scene. The cell membrane allows particles through to the cell that are vital for the cell to function, while keeping out unwanted substances.

Answer:
Enzyme Active Site and Substrate Specificity
Enzymes bind with chemical reactants called substrates. There may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. In some reactions, a single-reactant substrate is broken down into multiple products.
Explanation:
In transcription, the mRNA strand is formed by complementary base pairing of the template DNA strand. However we should note that the nitrogenous bases in mRNA are Adenine, Guanine, Cytosine and
Uracil
, while those in DNA are Adenine, Guanine, Cytosine and
Thymine
.
So the mRNA strand would be formed by matching the
A in DNA with U in mRNA
,
T in DNA with A in mRNA
,
C in DNA with G in mRNA
and
<span>G in DNA with C in mRNA</span>
The answer is B) Detritivore
I don't get your question, this can be helpful though
To explore the Hardy-Weinberg equation, we can examine a simple genetic locus at which there are two alleles, A and a. The Hardy-Weinberg equation is expressed as: p² + 2pq + q² = 1. where p is the frequency of the "A" allele and q is the frequency of the "a" allele in the population.
Goodluck
