Answer:
C
Explanation:
Membranes will allow and inhibit certain ions/molecules. I don't believe it can distinguish whether the molecules are harmful or beneficial!
Answer:
(a) number of strands (n) = time (t) ÷ proportionality constant (k)
(b) The time needed for the bacterial to double its initial size is 3.36 hours.
Explanation:
(a) Let the rate (time) be represented by t and the amount (number) of strands of bacteria be represented by n
t is proportional to n, therefore, t = kn (k is the proportionality constant)
Since t = kn, then, n = t/k
(b) Initial amount of strands = 300
Amount of strands after 2 hours = 300 + (300 × 20/100) = 300 + 60 = 360
k = t/n = 2/360 = 0.0056 hour/strand
Double of the initial size is 600 (300×2 = 600)
Time (t) needed for the bacterial to double its initial size = kn = 0.0056×600 = 3.36 hours
A wind blowing would be the right solution, as it's not an example of which value and energy cycling's happening through living items. Mortal sitting vegetables involve energy transfer between diverse trophic levels.
There would still be a 50% chance for the offspring to be Heterozygous (Hybrid), but then there would be another 50% chance for the offspring to be Homozygous recessive (True-breeding short plants)
Answer: They are the stop codon
Explanation: At the end of and mRNA squence there are three nucleotides that tell the ribosome to end the protein being made.
